Sovereign credit rating agencies react to fiscal signals in under 24 hours — yet the same models show no detectable response to structural capacity investment deficits over a 76-month observation window. This asymmetric signal structure is the core finding. Bond spreads across three comparator pairs (FI-DE, FI-SE, FI-DK) produce no deviation outside the historical interquartile range during the parliamentary processing of Finland's energy strategy review (VNS 8/2025 vp). Each pair carries a distinct confound — eurozone safe-haven premia, Riksbank/ECB monetary divergence, and a large-cap corporate shock — yet the null finding is robust across all three. This pattern is consistent with, but does not prove, a structural limitation: credit rating models optimise for short-term fiscal flow and are blind by design to long-horizon capacity investment quality. The paper further documents three cross-country investment pipeline archetypes that are indistinguishable in bond data despite radically different integration quality: national champion selection (Denmark), EU instrument absorption (Spain, Poland), and permissive attraction without integration (Finland). Energy prices are visible to rating models; energy capacity is not.
The Aether Continuity Institute has documented a structural phenomenon in Finnish institutional decision-making: D-suppression, in which identified risks pass through a three-stage filter (D1: signal → report; D2: report → agenda; D3: agenda → decision) with significant delays at each transition. The energy capacity gap documented in ACI's Finnish energy system structural report provides a concrete case: the risk has been identified, reported, and placed on parliamentary agenda under VNS 8/2025 vp, but no legislative capacity mechanism decision has followed.
The research question is: Do financial markets price D-suppression — the failure of identified risks to become binding decisions — before it manifests in fiscal indicators? This is motivated by a governance accountability argument. If markets detect decision-making capacity gaps with a measurable lead time, this creates a transparent signal that institutional actors cannot plausibly deny.
The null finding produces a secondary motivation: if rating agencies do not penalise capacity investment deficits, the political pressure to build such capacity is systematically reduced. D-suppression is not only a slow decision-making process — it is a process that lacks an external sanction mechanism. This is one reason the Salazar mechanism hypothesis (§4.3) is analytically important: if it operates, the rating framework actively rewards the behaviour that produces D-suppression.
The hypothesis was revised following the pilot data. The original formulation — that markets anticipate D-suppression — is replaced by: bond spreads delay D-suppression pricing, reacting typically with a 2–5 year lag and only after the problem has manifested. The reframed question is: which instrument detects D-suppression earliest, and with what lead time?

The FI-DE spread narrows monotonically: 0.60 pp average in 2023, 0.53 pp in 2024, 0.40 pp in 2025. Distribution: mean 0.505 pp, median 0.50 pp, range 0.35–0.65 pp (Q1: 0.42, Q3: 0.59). The trend is monotonic, not outlier-driven. During the D1-D2 transition (October–December 2025) the spread narrows from 0.40 to 0.35 pp — opposite to the original hypothesis. In early 2026 a minor widening of 0.065 pp occurs at D2/committee phase, within normal variation.
Identification note: FI-DE isolates the common ECB monetary policy but does not fully control for residual components — German Bund liquidity premium, issuance dynamics, inflation expectation differentials. These are second-order relative to the Riksbank problem (§2.3) and unlikely to reverse the null finding. A regression controlling for ECB policy rate and euro-area risk proxy is identified as a v1.1 extension.
FI-DE spread does not detect D-suppression. AAA-Finland is priced close to Germany regardless of energy policy decision latency. The monotonic narrowing reflects fiscal convergence within the eurozone common monetary framework, not D-suppression detection.
FI-SE spread was negative throughout 2020–2021 (range −0.18 to −0.53 pp): Finland's yield was lower than Sweden's. This is a clean monetary policy signal — Riksbank did not cut at ECB pace during COVID. The spread flipped positive in mid-2022 as energy crisis and Riksbank normalisation interacted. In summer 2024 it widened dramatically to 0.88 pp as Riksbank cut aggressively while Finland followed ECB. This placebo period confirms that FI-SE measures Riksbank/ECB divergence, not Finland-specific structural risk.
FI-SE spread is contaminated by monetary policy divergence. Finland's eurozone membership — ceding monetary policy to ECB — makes FI-SE an impure instrument for D-suppression detection. The 2020–2021 negative spread (Finland cheaper than Sweden) validates the instrument's sensitivity to monetary regime differences while confirming its unsuitability as a policy decision proxy.
FI-DK spread was near-zero in 2020–2021 (0.06–0.29 pp), then widened to 0.53–0.73 pp in 2025–2026. Unlike FI-SE, this cannot be attributed to monetary policy divergence — Denmark shadows ECB through ERM II. The most parsimonious explanation is a large-cap corporate shock: Novo Nordisk fell approximately 75% from its mid-2024 peak following competitive pressure from Eli Lilly and US pricing headwinds, prompting Denmark to cut its 2025 GDP growth forecast from 3.0% to 1.4%. The Nokia parallel is direct: just as Nokia's collapse dominated Finnish macroeconomic readings in 2000–2003, Novo Nordisk's correction dominates Danish sovereign risk pricing in 2024–2026. FI-DK cannot be used as a clean energy-policy comparator without controlling for this effect. This interpretation is parsimonious but not formally identified; isolating firm-level effects from sovereign spreads is left for future work.
Each spread pair carries its own confound: FI-DE is contaminated by safe-haven and liquidity premia; FI-SE by Riksbank/ECB monetary divergence; FI-DK by a large-cap corporate shock. Across all three pairs, no spread detects the D1-D2-D3 transition of VNS 8/2025 vp. The null finding is robust to comparator choice.
Sovereign credit rating agencies use five-pillar models assessing institutional quality, economic structure, external position, fiscal strength, and monetary flexibility. Each pillar is scored on realised historical data. Investment pipelines — infrastructure modernisation, energy capacity mechanisms, PtX development — are invisible to the model until they produce measurable GDP or fiscal impact, which may take 5–10 years. S&P's April 2026 statement on Finland is instructive: the agency called for "front-loaded measures" to stabilise debt. Front-loaded means: cut now, do not promise future growth. This incentive structure is structurally opposed to long-term capacity investment.
The 2008 financial crisis is the canonical empirical evidence of credit rating model blindness. Rating agencies assigned AAA to subprime CDOs using backward-looking correlation models that missed building structural gaps. At the sovereign level, Iceland, Ireland, and Spain held AA or above immediately before the crisis. The structural analogy to Finland is instructive but imperfect — it is structural, not empirical equivalence. In 2008, private debt transferred to the public balance sheet; in Finland, public decision-making failure transfers costs to the private sector on a 5–10 year horizon. Both cases share the common structure: the model rewarded short-term apparent stability while structural deterioration accumulated below the detection threshold.
Finland's situation is not idiosyncratic. Three synchronisation mechanisms produce the same allocation blindspot across OECD economies simultaneously:
| Mechanism | How it operates | Effect |
|---|---|---|
| Financial architecture | Pension funds, infrastructure funds, capital markets optimise short-term yield globally | Long-horizon capacity investment does not fit return models |
| Institutional standards | OECD fiscal rules, EU Stability and Growth Pact, EDP optimise short-term budget balance | Category II investments penalised vs. current expenditure reduction |
| Risk pricing models | S&P, Fitch, Scope, Moody's use identical five-pillar frameworks globally | Same blindspot simultaneously in all OECD member states |
This is consistent with ACI's RQM-001 finding (Correlated Continuity Blindspots in OECD Infrastructure Allocation, companion to WP-008/WP-009): the continuity-blind investment filter may be a transnational correlation risk rather than a national policy failure. RQM-001 asks whether a shared selection filter operates beneath conscious policy formation; WP-017's spread analysis provides the bond market answer — the signal does not exist in these instruments.
The ECB's mandate is price stability — not investment capacity or structural resilience. Its single eurozone rate applies equally to Finland (which has not legislated a capacity mechanism) and France (which has). This creates an institutional cushion that hides national decision-making gaps in bond pricing. A country can delay capacity investment indefinitely without its bond yield diverging, as long as its fiscal flow remains within acceptable parameters.
The bond spread blindspot extends beyond absent investment to a subtler failure: investment that occurs without the systemic integration required to generate economic benefit. Finland's wind power capacity provides a concrete illustration. Approximately 7,000 MW has been built or committed — attracted by a permissive regulatory environment. This is a genuine investment success by volume. By another measure, it represents an unresolved coordination failure: no PtX roadmap, no industrial coupling strategy, no data-export framework that would convert variable generation into tradeable value. Single-sector lobbying has substituted for systemic planning. The bond market sees capacity being built; it cannot see that the integration layer is absent.
The same phenomenon is observable in Finnish data centre development: approximately 500 MW is operational with a further 3–5 GW in the investment pipeline. Data centres bring fiscal investment visible to rating models. What is not visible: the systemic integration layer. DT-004 documents that data centres can connect via PPAs without creating new capacity, and that TEM's flexibility mechanism proposal (800 MW by 2030) remains voluntary and market-based — not a mandatory demand-response framework. Capacity is being installed; binding systemic integration is absent. The Salazar mechanism may apply here directly: front-loaded investment improves the fiscal profile; the absence of an integration mandate does not appear in bond pricing. The bond spread cannot distinguish between integrated and unintegrated data centre capacity.
The contrast between Finland and its peers reflects structurally different models of investment pipeline activation. Three archetypes are observable:
| Type | Mechanism | State capacity required | Bond market visibility | Risk |
|---|---|---|---|---|
| I — National champion Denmark |
Active industrial selection + state ownership. Ørsted (state 51%) became the world's largest offshore wind developer. Life Science Strategy 2030 targets DKK 350 billion in annual pharmaceutical exports. Bornholm Energy Island: 3 GW cross-border interconnector, €645 million EU funding. | Strategic planning, ownership management, long-term commitment | Partially visible — investment occurs, export earnings appear in fiscal data | Concentration shock: Novo Nordisk -75% from 2024 peak; Denmark GDP forecast cut 3.0%→1.4% |
| II — EU instrument absorption Spain, Poland |
Systematic access to RRF, cohesion, and structural funds. Poland: €43.7 billion total allocation, largest CEE beneficiary. Spain: large RRF recipient, plan amended and expanded through 2025. | Administrative capacity for milestone compliance, procurement, cross-ministry coordination | Invisible — treated as external transfer, not domestic capacity | Absorption failure: Poland transferred only PLN 10 billion to final beneficiaries by end-2024 despite €23 billion remaining. OECD: "absorption slowed by limits on administrative capacity to spend." |
| III — Permissive attraction without integration Finland |
Regulatory permissiveness attracts private wind capital. 7,000 MW built or committed. No systemic integration layer — PtX, industrial coupling, export strategy absent. Finland's RRF allocation €2.1 billion — modest, reflecting lower administrative pipeline capacity. | Minimal — regulatory clearance only. No integration architecture. | Partially visible — investment occurs | Integration failure: capacity installed but not utilised systemically. Lobby substitution for planning. |
This typology is illustrative rather than formally identified — the three cases are selected to demonstrate the range of archetypes, not to constitute a representative sample. Systematic cross-country comparison would require a standardised IQS measurement framework (registered as WP-018). All three types share a common property visible in the data: bond spreads cannot distinguish between them. All show investment occurring — the spread does not detect whether investment produces systemic benefit or remains unintegrated. The distinction between capacity installed and capacity integrated is precisely the gap that credit rating models cannot close.
| Agency | Rating | Outlook | Last action |
|---|---|---|---|
| Fitch | AA | Stable | Downgraded AA+→AA July 2025 (negative outlook August 2024) |
| Scope | AA+ | Negative | Negative outlook August 2025 |
| S&P | AA+ | Negative | Negative outlook 24 April 2026, 23:04 EEST; next review October 2026 |
| Moody's | Aa1 | Stable | No change — only holdout |
S&P reacted to Finland's fiscal framework review (kehysriihi) in under 24 hours, recording the outlook change at 23:04 EEST on 24 April 2026. The stated rationale: "persistent risks to public finances stemming from low growth, ageing demographics, and rising defence and interest expenditure." Energy appears only as a contextual factor: policymakers must "adapt to the impact that the crisis in the Middle East is having on energy prices." Energy prices are visible to rating models; energy capacity is not.
This asymmetry is the core empirical finding of this paper. When the signal is fiscal and immediate, the reaction is fast and precise. When the signal is structural and long-horizon — capacity investment deficit, integration failure, D-suppression — the reaction is absent within the observation window. The model is not inefficient; it is optimised for a different signal class.
Fiscal signals produce sub-24-hour sovereign rating reactions. Structural capacity signals produce no detectable rating reaction within a 76-month observation window. This asymmetry is not a market failure — it is the predictable output of models optimised for short-term fiscal flow measurement.
The asymmetry finding generates a theoretical implication rather than a directly tested claim. The rating agency framework rewards front-loaded fiscal consolidation and does not positively weight long-term capacity investment pipelines. This creates an asymmetric incentive: a government that cuts Category II investments improves its short-term fiscal profile and may stabilise its outlook, while a government that maintains such investments faces downgrade pressure even if they improve long-term debt-carrying capacity. This is the proposed Salazar mechanism.
The original Salazar hypothesis was framed around a binary shock model: a single rating event penalises capacity investment and compresses the investment horizon. The geopolitical context of 2026 — specifically the persistent R2 regime in Hormuz strait traffic — reveals a structurally more dangerous variant: chronic sub-threshold friction that produces the same outcome as a discrete shock, but without generating a clear political reaction point.
A four-regime model clarifies the distinction:
| Regime | Description | Pricing mechanism | Fiscal effect |
|---|---|---|---|
| R0 Open | Normal traffic, baseline insurance | Base price | Baseline — absorbed by Nordic market integration |
| R1 Restricted | Selective access, risk premia, insurance stress | Risk premium +20–40% | Gradual — industry surcharges begin activating |
| R2 Contested | Military control conflict, partial traffic, oscillating closure risk | Uncertainty premium dominates; markets price expectation not physical flow | Unstable, cyclical — EDP headroom erodes quarter by quarter |
| R3 Blockaded | Effective closure, dual-lock | Physical scarcity | Acute shock — ECB instruments activate |
The current Hormuz situation is R2 — not R3. This distinction is methodologically critical. R3 is paradoxically easier to model: a single shock, clear transmission, measurable political response. R2 operates differently: insurance markets can effectively close a route before a single vessel is threatened; oscillations between partial opening and closing prevent the sustained political response that R3 would trigger; ECB instruments (TPI, OMT) are calibrated for R3 — a persistent R2 friction advances below their activation threshold.
For Finland, the R2 critical zone is approximately TTF above ~50 €/MWh persistently: industrial surcharges activate, corporate tax revenues erode, and the EDP correction path narrows quarter by quarter. No single quarter constitutes a crisis event requiring ECB intervention. Each quarter is "managed" individually. D-suppression continues because no single event forces a decision — the Salazar mechanism operates not through one catastrophic rating action but through cumulative compression of fiscal headroom below the threshold at which structural capacity investment becomes politically defensible.
The binary shock formulation of the Salazar hypothesis understates the mechanism. Geopolitical friction at R2 level produces the same long-run outcome as a discrete R3 event — compressed investment horizons, rating pressure, foregone capacity correction — but does so without a clear political reaction point. This is structurally more dangerous than a single catastrophic event: R3 triggers political response; R2 advances below the detection threshold of both ECB instruments and parliamentary agenda-setting. Chronic under-diagnosis, not catastrophe, is the dominant failure mode.
The regime model generates a concrete quantitative question: at what TTF level and for what duration does Finland's EDP correction path break down computationally? Three parameters are calibrated from 2025–2026 fiscal data.
Parameter 1 — TTF elasticity on industrial tax revenue. Finland's energy-intensive industry (pulp, metals, chemicals) represents approximately €43 billion or 15% of GDP. For this sector, a TTF increase of 10 €/MWh raises production costs by 1.5–2.5% of turnover; with typical operating leverage, this reduces profits by 4.5–7.5%. At Finland's effective corporate tax rate (~15%), each 10 €/MWh TTF increase removes approximately 290–490 M€/year from corporate tax revenues. Elasticity estimate: −30 to −50 M€/year per €/MWh TTF increase.
Parameter 2 — Interest expenditure sensitivity to spread widening. Calibrated from official Valtiokonttori interest rate sensitivity data (api.tutkihallintoa.fi/central-government-debt/v1/interest-rate-sensitivity, retrieved 2026-04-26, updated 2026-04-22). Central government debt end-March 2026: €194.34 billion. Key sensitivity parameters as of March 2026:
| Parameter | Value | Implication |
|---|---|---|
| averageMaturity | 7.77 years | Average time to debt maturity — sets long-run refinancing pace |
| averageFixing | 5.43 years | Average time until interest rate resets — determines annual repricing volume |
| duration | 4.15 years | Modified duration — price sensitivity to rate changes |
The averageFixing of 5.43 years implies annual repricing of 1/5.43 = 18.4% of the portfolio = €35.8 billion per year. Interest cost sensitivity: +10 bps → €36 M€/year (immediate); rising to €194 M€/year as the full portfolio reprices over 5.4 years. Interest expenditure budget 2026: €3.2 billion (TAE 2026).
Debt scope note: VK-DEBT-GDP series (Valtiokonttori) records central government budgetary debt at €187.7 billion (66.7% GDP) at end-2025 — approaching the 1990s crisis peak of 64.8% (1996). This is the base to which VK-SENSITIVITY applies. EDP-reported general government debt (Statistics Finland) is €248 billion (88.5% GDP) and includes municipalities, wellbeing areas, and social security funds. The P2 calibration uses the correct VK central government portfolio for sensitivity calculations.
Empirical validation from VK-INTEREST historical series (1990–2026). The 2022–2023 rate shock provides a natural experiment. Interest expenses rose from €840M (2022) to €2,323M (2023), an increase of €1,483M. Decomposed: rate effect (€24B annual repricing × 350 bps ECB hike) = €840M; volume effect (debt grew €110B→€140B at ~2% average) = €600M; theoretical total = €1,440M against actual €1,483M — within 3%. The VK-SENSITIVITY mechanism is validated empirically. Structural finding from the full 1990–2026 series: interest expenses now exceed €3 billion per year as a permanent structural item, surpassing the 1993 level (€3,088M) in nominal terms. At projected 2028 debt levels (~€220 billion), interest expenditure will reach €3.5–4.0 billion per year at 2.5–3.0% rates — exceeding the EDP correction requirement (€1.4 billion per year) as a fixed structural item regardless of spread movements.
Parameter 3 — EDP correction requirement and available headroom. Finland's general government deficit was 3.4% of GDP in 2025 (€9.6 billion), exceeding the SGP 3% threshold. The EU national escape clause has been activated for Finland for 2025–2028. The SGP correction requirement is approximately 0.5% GDP per year — €1.44 billion annually. Historical R2-condition precedents (Greece, Portugal, Spain 2011–2015) produced 2–4 years of additional time but with increasing conditionality and structural reform requirements.
Stress scenario result — model-calibrated, not observed. Under a stylised R2 scenario of TTF +20 €/MWh persistently and spread +20 bps simultaneously, the combined estimated fiscal impact is €634–1,468 M€/year. Against the EDP correction requirement of approximately €1,440 M€/year, R2 friction would consume 44–102% of available headroom. This range is wide and reflects genuine uncertainty in the underlying coefficients — it is a stress envelope, not a point estimate.
TTF at ~50–60 €/MWh sustained for two or more quarters increases the probability of EDP correction path failure — it does not mechanically determine it. The threshold is conditional on fiscal space remaining below a critical level and spread sensitivity remaining above a critical level simultaneously. What is deterministic is the direction: R2 persistence erodes fiscal headroom quarter by quarter without producing a discrete political reaction point. The trajectory is not stochastic in direction, only in speed.
Observation: Finnish industrial natural gas was approximately 50.1 €/MWh in August 2025 — at the lower bound of the stress envelope, before the Hormuz R2 escalation of Q1 2026. This is a descriptive data point, not a causal claim.
WP-017 v1.6 contains three analytically distinct layers that should not be conflated:
| Layer | Type | Examples | Identifiability |
|---|---|---|---|
| A — Observed data | Direct measurement | Eurostat bond spreads, S&P rating action timestamp, TTF price, Finnish gas price 50.1 €/MWh | High — directly measurable |
| B — Model-calibrated coefficients | Structural estimates from macro aggregates | P1 TTF elasticity (−30 to −50 M€/€/MWh), P2 spread sensitivity (26–248 M€/10bps) | Medium — estimable from observed aggregates, sensitive to structural assumptions |
| C — Latent regime boundaries | Inferred from structural reasoning | P3 critical threshold (50–60 €/MWh), R0/R1/R2/R3 regime boundaries, D-suppression detection threshold | Low — not directly observable; inferred from institutional behavior and fiscal constraint interaction |
The Salazar mechanism hypothesis becomes a measurable claim only at Layer A — the asymmetric reaction speed is directly observable. At Layer B, the fiscal transmission is estimable but uncertain. At Layer C, the regime threshold is a latent structural variable requiring a different identification strategy: either natural experiments (historical R2 episodes in comparable small states) or formal DSA (Debt Sustainability Analysis) under the EU Commission's DSGE framework. Conflating layers A, B, and C would overstate what WP-017 has established empirically.
Identifying Layer C variables — latent regime boundaries — requires natural experiments where R2→R3 transitions have been observed. Portugal 2010–2011 is the closest comparable within the eurozone framework: a small open economy, eurozone member, EDP-subject, facing persistent fiscal friction that escalated to a market-closing event without a single discrete shock.
| Variable | Portugal 2010–2011 (observed) | Finland 2025–2026 (observed) |
|---|---|---|
| Deficit % GDP | 11.2% (after revision) | 3.4% |
| Debt % GDP | 93.0% | 88.5% |
| 10Y yield — R2 start | 5–6% (2010 Q1) | 3.25% (2026 Q1) |
| 10Y yield — R2 peak | 13.9% (2012 Q1) | Not yet — monitoring |
| PT-DE spread — R2 start | ~100–300 bps (2010 Q2) | ~40 bps FI-DE (2026 Q1) |
| Spread — momentum threshold | ~600 bps → non-linear acceleration | Not yet reached |
| Spread — market closure | ~1,200–1,700 bps (2012 Q1) | Not applicable (TPI) |
| R2 duration before forcing event | ~4–5 quarters (Q2 2010 – Q2 2011) | ≥2 quarters (ongoing) |
| Primary stress driver | Fiscal + banking + risk aversion cascade — not energy | Fiscal + Hormuz R2 friction + spread widening |
| ECB backstop | None (pre-OMT, pre-TPI) | TPI available (2022–) |
| Escape clause | No | Yes (2025–2028) |
| Forcing event | Cumulative confidence loss → IMF April 2011 | None yet |
Three structural findings emerge from the observed Portugal data:
Finding 1 — R2 duration before forcing event is 4–5 quarters; Finland's window is longer but not structurally different. Portugal operated in R2 for approximately four to five quarters before market access became unsustainable. Finland's structural advantages — escape clause, TPI availability, substantially lower deficit (3.4% vs 11.2% GDP) — extend the expected R2 window to 8–12 quarters. This is not reassuring: a longer window means more quarters of silent cumulative erosion. The ESM EFSF programme evaluation concluded that Portugal should have requested assistance earlier — the delay had financial and political consequences. The same logic applies to structural capacity investment decisions made during an extended R2.
Finding 2 — R2 detection requires second derivative (acceleration), not level. The critical empirical observation from Portugal is that the forcing event was not triggered by a single rating action or discrete shock. It was triggered by momentum: spreads moved from ~300 to ~600 bps non-linearly, then accelerated to 1,200–1,700 bps as refinancing constraints interacted with liquidity retreat. The relevant diagnostic variable is d²spread/dt² — the acceleration of spread widening — not the absolute spread level. For Finland, FI-DE at 40–47 bps is stable and low. The diagnostic question is not "is the spread high?" but "what would trigger acceleration?" The Portugal answer: cumulative credibility loss from repeated fiscal revision + rating cascades.
Finding 3 — Fiscal consolidation without growth recovery produces a deteriorating net EDP path. Portugal cut its deficit toward EDP targets — but growth deteriorated at the same pace. The net EDP path did not improve at the headline fiscal measure rate. This is the concrete historical evidence for WP-017's core argument: a government that front-loads fiscal consolidation without addressing structural capacity investment compresses its growth potential, which weakens the fiscal position, which increases spread pressure. The mechanism operated in Portugal across three years before breaking. ECB TPI availability slows this cycle for Finland — it does not interrupt it.
Portugal 2010–2011 validates the R2 regime model's Layer C logic. The R2→R3 transition took four to five quarters and was triggered by spread momentum — specifically the second derivative (acceleration), not the absolute level. The absence of ECB backstop tools accelerated the transition; Finland's TPI availability slows it without changing the direction. The most policy-relevant finding is Finding 3: consolidation without growth recovery does not close the EDP path — it narrows the fiscal space available for structural capacity investment, which is the variable that determines long-horizon debt sustainability. This is WP-017's core argument in historical form.
The Portugal comparator establishes that R2 detection requires the second derivative of spread dynamics, not the level. This section presents a first implementation of an R2 Detection Index (RDI) calibrated against the Portugal threshold and applied to observed FI-DE spread data.
Signal architecture:
| Signal | Formula | Weight | Captures |
|---|---|---|---|
| S1 — Slope | Δspread / Δt (pp/month, 3M window) | 0.25 | Direction of spread movement |
| S2 — Acceleration | ΔS1 / Δt (pp/month², 3M window) | 0.55 | Non-linear momentum — the Portugal signal |
| S3 — Level | max(0, (spread − Q3) / IQR) | 0.20 | Deviation above historical IQR |
RDI = 0.25·S1 + 0.55·S2 + 0.20·S3
Portugal calibration (heuristic, FI-scaled): At Portugal's R2 onset, the spread was rising approximately 30–50 bps/quarter (~10–17 bps/month). The FI-DE spread baseline is approximately 6× lower than PT-DE at comparable stress levels. FI-scaled detection thresholds: S1 > 0.010 pp/month, S2 > 0.008 pp/month². These are starting-point estimates, not identified parameters.
Pilot results (FI-DE, 2024–2026): Applying RDI to observed Eurostat FI-DE data identifies four months where both S1 and S2 exceed the Portugal-calibrated threshold:
| Date | Spread (pp) | S1 slope | S2 accel | RDI | Note |
|---|---|---|---|---|---|
| 2024-08 | 0.570 | +0.030 | +0.053 | +0.037 | Summer widening — minor |
| 2026-01 | 0.447 | +0.017 | +0.023 | +0.017 | Post-Hormuz onset |
| 2026-02 | 0.417 | +0.013 | +0.027 | +0.018 | Continuation |
| 2026-03 | 0.413 | +0.020 | +0.036 | +0.025 | Strongest Q1 signal |
FI-DE spread data shows weak R2-consistent signals in Q1 2026 — marginally above Portugal-calibrated thresholds in three consecutive months. The signal is weak in absolute terms (RDI 0.017–0.025 vs. Portugal peak RDI which would be an order of magnitude higher) and is consistent with noise rather than genuine R2 onset. However, three consecutive months of above-threshold S2 acceleration is a pattern worth monitoring. The finding is consistent with the paper's null finding in §02: no strong D-suppression signal exists in bond spreads. The Q1 2026 micro-signal may reflect Hormuz R2 friction beginning to transmit — but at levels indistinguishable from normal variation without additional confirmatory data (CDS, term spread).
The R2 detection function is the first step toward making the Layer C regime boundary empirically operational. The 2Y-10Y term spread slope is implemented as a second confirmatory signal — see Finding 4.5 below.
The 2Y-10Y term spread is constructed as a proxy: Finnish 10Y yield (Eurostat irt_lt_mcby_m) minus the ECB deposit rate + 0.15 pp credit spread approximation for Finnish 2Y. This is an approximation — Finnish 2Y yield is not directly available in free public sources. The methodological limitation is acknowledged; the proxy captures the structural direction of the yield curve even if the level is imprecise.
Term spread history — calibrated series. The 2Y yield proxy is calibrated against a directly observed anchor: Finnish 2Y yield = 2.01% in August 2025 (Trading Economics / OTC interbank quotes). The proxy underestimated FI 2Y by 11 basis points; all values are corrected by +0.11 pp. Calibration does not alter the directional finding.
Curve history: inverted deeply during ECB hiking cycle (peak inversion −0.90 pp, September 2023). Normalised rapidly during 2025 as ECB cut rates while Finnish 10Y remained elevated — peak term spread +1.155 pp in December 2025, reflecting growth expectation recovery. In Q1 2026 the curve flattens sharply: −0.411 pp over three months (December 2025 → March 2026). Monthly slope: −0.071 (January), −0.243 (February), +0.062 (March recovery). The December–February move is the steepest three-month flattening in the full series.
| Date | FI 10Y | FI 2Y (adj) | Term spread | Monthly slope |

| 2026-03 | 3.323% | 2.76% | +0.563 pp | +0.062 |
Combined detection threshold (FI-scaled): Term spread slope below −0.050 pp/month signals yield curve flattening consistent with R2 stress onset.
FI 5Y CDS — data limitation. Finnish sovereign CDS is not available in free public sources. The ESRB (2025) characterises single-name sovereign CDS markets as shallow and illiquid — even Italy averages only 13 trades per day. For a AAA-tier sovereign such as Finland, the market is thinner still. Historical estimates place FI 5Y CDS at 10–20 bps. A third confirmatory signal via CDS requires commercial data access (Bloomberg, MacroMicro). This is documented as an open data gap; the dual-signal finding stands on the two available instruments.
Both the FI-DE spread S2 (acceleration) and the term spread slope simultaneously exceed Portugal-calibrated thresholds for three consecutive months in Q1 2026, coinciding with the Hormuz R2 escalation. Calibration with the observed FI 2Y anchor (2.01%, August 2025) confirms the directional finding.
| Date | FI-DE S2 accel | TS slope pp/m | Signal |
|---|---|---|---|
| 2026-01 | +0.023 | −0.411 | DUAL |
| 2026-02 | +0.027 | −0.243 | DUAL |
| 2026-03 | +0.036 | +0.062 | S2 only (TS recovering) |
The term spread slope in March recovers above threshold — the flattening is not accelerating further as of the latest observation. This is consistent with partial stabilisation: the initial Hormuz shock transmitting through the curve, then partially reversing as markets price in TPI backstop probability. The DUAL pattern lasted two months; the S2 acceleration persists into March.
Interpretation: weak but consistent early R2 signal. Both instruments respond in the same direction for the first time in the series, at a moment of identified geopolitical R2 onset. Absolute levels remain low — this is not a crisis signal.
Orthogonality caveat: The FI-DE spread S2 and the term spread slope are not fully independent signals. Both are derived from the same sovereign yield curve: FI-DE spread reflects Finland's 10Y yield relative to Germany; the term spread reflects the slope of Finland's own curve. Both share the same latent driver — the common eurozone interest rate structure plus Finland-specific credit components. The dual signal is therefore not the conjunction of two independent confirmatory instruments; it is two representations of partially shared latent variation. A genuine independent third signal requires a different asset class — 5Y CDS (credit risk, not rate structure) or equity volatility (risk appetite). The dual signal is suggestive but not conclusive. Third confirmatory signal (5Y CDS) requires commercial data.
WP-017 is currently a signal decomposition framework with strong descriptive resolution but weak causal identification. The R2 regime model is conceptually productive but not yet falsifiable from Layer A data alone. The structural invisibility hypothesis (markets see fiscal flow, not capacity investment quality) is the paper's most robust contribution — and it does not require the R2 regime model to be true. The following falsification plan specifies what evidence would close or refute each major claim.
| Claim | Falsification criterion | Data required | Status |
|---|---|---|---|
| Bond spreads do not detect D-suppression within 76 months | Any D-phase event produces FI-DE spread deviation outside IQR (Q1-Q3 = 0.42–0.59 pp) within 6 months | Eurostat irt_lt_mcby_m — available | Tested — null finding confirmed |
| R2 regime produces spread acceleration before spread level crisis (S2 precedes S3) | In a confirmed R2→R3 transition for a TPI-era eurozone member, spread level (S3) rises before acceleration (S2). If S3 precedes S2, R2 detection logic is inverted. | Requires a TPI-era sovereign stress event — not yet available (Portugal pre-dates TPI) | Open — untestable until next stress event |
| Salazar mechanism: front-loaded consolidation penalises capacity investment | Cross-country panel regression finds no negative correlation between Category II investment share and rating outcomes after controlling for deficit/GDP and debt/GDP | OECD investment composition data + Moody's/S&P rating action database | Open — criterion A (rating text analysis) feasible now |
| IQS predicts differential fiscal outcomes across investment pipeline archetypes | Countries with IQS > 7 show lower long-run energy cost volatility or higher export earnings than Type III countries, controlling for GDP and energy mix | OECD energy price data + IQS scores from WP-018 extended case set | Open — requires case expansion to ≥10 countries |
| RDI weights (0.25/0.55/0.20) are approximately correct | Alternative weight vectors (e.g. 0.10/0.80/0.10 or equal weights) produce materially different R2 onset dates in historical stress episodes | Historical stress event database — Portugal, Italy 2011, Spain 2012 | Immediate — requires only existing data and parametric sensitivity |
The most tractable immediate falsification test is RDI weight sensitivity. If applying alternative weight vectors to the Portugal 2010–2011 and Italy 2011–2012 stress episodes produces RDI signals with materially different timing, the heuristic weights cannot be distinguished from noise and the index requires formal estimation. If the rank ordering of stress months is robust across weight vectors, the directional finding is weight-insensitive and can be treated as more reliable. This test uses only data that already exists in this paper's dataset.
The core finding that bond spreads react asymmetrically to fiscal signals (sub-24 hours) versus structural capacity signals (no detectable reaction in 76 months) is Layer A — directly observed, not modelled. This finding does not depend on RDI weights, Portugal calibration, CDS availability, or the R2 regime model. It stands independently. The R2 model, the Salazar mechanism, and the IQS framework are theoretical extensions built on this empirical foundation. They may be wrong in their specific formulations; the asymmetry finding is not.
The structural blindness of credit rating models to long-term sustainability investment is an academically recognised problem. The UN Department of Economic and Social Affairs (2023) states that investments in resilience and climate adaptation can materially enhance a country's future debt-carrying capacity even when they increase short-term debt, and notes that rating methodology updates have been slow and typically reactive to past crises.
Recent empirical work (ScienceDirect, 2025) demonstrates that sovereign downgrades do not merely reduce aggregate investment — they reallocate capital from long-term to short-term projects. This is an empirical confirmation of the asymmetric incentive structure: rating pressure forces investment horizon shortening precisely when long-term capacity investment is most needed.
Moody's own methodology (2022) acknowledges environmental shocks and demographic change as growth determinants but retains operational weight on fiscal strength and short-term resilience. Long-term capacity investment is not a standalone positive variable in current agency frameworks.
The 2008 financial crisis provides the canonical precedent: agencies assigned AAA to CDOs using backward-looking correlation models that missed building structural gaps. Iceland, Ireland, and Spain held AA or above immediately before sovereign stress events. The common mechanism — rating stability masking structural deterioration — recurs across asset classes and decades.
The pilot produces no evidence that bond spreads detect D-suppression within the observed 76-month window. This is consistent with, but does not prove, a structural limitation: rating models are backward-looking by design, and capacity investment deficits materialise on a horizon that exceeds their forward visibility. The absence of a signal in this pilot does not establish structural impossibility — it establishes that the signal, if present, lies below detection threshold in the instruments tested. Detection threshold is defined here as spread variation exceeding the historical interquartile range (Q1–Q3 = 0.42–0.59 pp for FI-DE). No D-phase event produces spread deviation outside this range.
The cross-country typology (§3.6) generalises the finding: all three investment pipeline archetypes — national champion selection, EU instrument absorption, permissive attraction — are indistinguishable in bond spread data. The spread detects fiscal flow; it is structurally blind to investment quality and systemic integration. This is the generalised form of the blindspot.
The asymmetry (§4.2) is the paper's sharpest empirical result: sub-24-hour fiscal reaction, 76-month structural non-reaction. It is not that markets are inefficient. It is that rating models are optimised for a signal class that does not include capacity investment deficits.
This paper identifies the gap between capacity installed and capacity integrated as the core undetected variable in bond pricing. A natural extension — Integration Quality Score (IQS) — would operationalise this gap as a constructed index measuring the systemic coupling of installed capacity across four dimensions: physical capacity, systemic linkage (integration layer), policy anchor, and export potential. IQS would be the energy-system analogue of HDCI (WP-016): a diagnostic instrument for what the market cannot see. The concept is registered as WP-018 in ACI-STRUCTURE.md.
| Instrument | Hypothesis | Priority |
|---|---|---|
| 2Y–10Y term spread (FI) | Yield curve slope reacts to policy expectations faster than 10Y level; free from Eurostat | First — immediate |
| 5Y CDS spread | Most sensitive to near-term event risk; cleaner than bond yield | Second — requires commercial data |
| Content analysis of rating statements | Tests Salazar mechanism Criterion A — does capacity investment appear as independent factor? | Third — feasible with public data |
| OMXH25 volatility | Supporting instrument only — dominated by Nokia/Nordea idiosyncratic noise | Supporting |
Sovereign credit markets react to fiscal signals in under 24 hours and show no detectable response to structural capacity investment signals over 76 months. This asymmetry is not a market failure — it is the predictable output of rating models optimised for short-term fiscal flow. The governance implication is direct: in the absence of a market sanction, the political pressure to build long-horizon capacity is structurally reduced. D-suppression operates in part because the external signal that would punish it does not exist in the instruments currently priced.
Bond spreads and credit ratings are necessary but insufficient indicators of long-term state sustainability. They measure the ability to service current debt — not the ability to build future capacity. This paper provides evidence consistent with a structural limitation in OECD sovereign risk pricing frameworks. Formal demonstration requires cross-country panel evidence beyond the scope of this paper. Energy prices are visible to rating models; energy capacity is not.
This appendix formalises the fiscal trajectory underlying the §4.5 critical threshold analysis as a simulatable quantitative model anchored to official Valtiokonttori data. The model replaces narrative scenario description with a dynamic debt accumulation equation and Monte Carlo uncertainty quantification.
Debt accumulation:
Dt+1 = Dt + PDt + ieff,t · Dt
GDPt+1 = GDPt · (1 + gt)
Interest cost uses VK-SENSITIVITY portfolio repricing mechanics: averageFixing = 5.43 years → 18.4% of the portfolio reprices annually. Effective interest rate evolves as:
ieff,t+1 = (1 − 0.184) · ieff,t + 0.184 · imarket,t
This prevents the common error of applying market rates to the full legacy debt stock immediately. Validation: model produces €3.56 billion 2026 interest cost against TAE 2026 budget of €3.25 billion (~10% difference attributable to model using slightly higher marginal rate assumption).

Debt stabilises when the primary deficit is covered by the growth-rate differential: PD ≤ (g − i_eff) · D. Since g < i_eff in baseline and crisis scenarios throughout 2026–2032, debt grows endogenously without any external shock.

The model is not a crisis prediction. It is a structural drift diagnosis. In the median Monte Carlo path Finland's central government debt reaches approximately 85% of GDP by 2032 — approaching the 1990s banking crisis peak (64.8% in 1996 under a very different fiscal structure). This occurs without an external shock, driven entirely by the arithmetic of g < i_eff combined with persistent primary deficits. The key finding is the stability condition: stabilisation requires either a primary surplus, nominal growth above 4%, or a sustained collapse in interest rates. None of these is the baseline expectation for 2026–2032.
Historical context from VK-DEBT-GDP: Finland maintained debt below 40% of GDP for most of 1950–2008. Current trajectories represent a structural departure from this norm — not a cyclical deviation from it.
A policy regime without a capacity mechanism creates a structural incentive that the baseline model does not capture: capital-intensive, price-insensitive actors (hyperscale data centres) occupy grid capacity ahead of traditional industry. If industrial operators such as energy-intensive manufacturing respond by withdrawing investment from Finland, the fiscal impact is a double shock — growth falls (industrial productivity leaves) and the primary deficit rises (tax base erodes) simultaneously. Both variables move in the wrong direction at once.
Four scenarios are modelled with varying degrees of industrial displacement:
| Scenario | g (nominal) | Primary deficit | D/GDP 2028 | D/GDP 2030 | D/GDP 2032 | Δ vs baseline 2032 |
|---|---|---|---|---|---|---|
| Baseline stress | 2.5% | 2.5% GDP | 73.4% | 78.7% | 84.5% | reference |
| DC dominant, teollisuus jää | 2.0% | 2.8% GDP | 75.3% | 82.0% | 89.3% | +4.8 pp |
| Outokumpu-tyyppinen pako | 1.5% | 3.2% GDP | 77.8% | 86.5% | 96.2% | +11.7 pp |
| Teollisuuskollapsi + R2 | 0.8% | 3.8% GDP | 81.6% | 93.9% | 108.0% | +23.5 pp |
The Outokumpu-type scenario represents a structural adjustment where one or more large industrial operators redirect capital investment to jurisdictions with capacity guarantees. The −1.0 pp growth impact and +0.7 pp deficit impact reflect: loss of high-value industrial production from GDP, reduced corporate tax revenues, and partial offset from data centre fiscal contribution. The spread impact (+10 bps) reflects the rating sensitivity documented in §4.5 P2.
A laissez-faire capacity regime in which data centres obtain preferential grid access without additionality obligations produces a nonlinear fiscal outcome: the 2032 debt/GDP ratio reaches 96% under the Outokumpu-type scenario — 11.7 percentage points above the baseline stress path and approaching the 1990s banking crisis level. The mechanism is a double shock: growth falls as industrial capital leaves, and the deficit rises as the tax base contracts. Neither movement would occur under a capacity mechanism that required demand-side actors to finance the system adequacy they consume. The policy cost of the laissez-faire regime is therefore not only the adequacy gap itself but the fiscal trajectory it imposes on general government accounts over a 6–7 year horizon.
The industrial displacement analysis in §A.6 captures only the domestic fiscal consequence of capital flight. A complementary mechanism operates through the ownership structure of incoming investments: hyperscale data centres are typically owned by foreign holding companies with IP and profit structures registered in low-tax jurisdictions. This creates a fiscal extraction pattern that is invisible to GDP statistics during the construction phase but structurally significant in the operating phase.
| Variable | DC hyperscale (per GW installed) | Traditional industry (per GW consumed) |
|---|---|---|
| Ownership structure | Foreign holding company (Luxembourg/Ireland) | Finnish/Nordic, long-term domestic |
| Employment intensity | ~300 employees per GW | ~2,500 employees per GW |
| Annual wage bill | ~€19.5M/year | ~€130M/year |
| Income tax to Finland | ~€6.8M/year | ~€41.6M/year |
| Corporate tax to Finland | ~€1M/year (transfer pricing to parent) | ~€45M/year (effective rate ~15%) |
| Total fiscal contribution per GW | ~€7.8M/year | ~€86.6M/year |
| Ratio | Traditional industry generates 11× more tax revenue per GW consumed | |
The construction phase of a hyperscale investment does appear in Finnish GDP — typically €500M–€2B per facility in building contracts, equipment, and local procurement. This creates a one-time statistical boost that is frequently cited as evidence of investment success. The operating phase is structurally different: electricity is purchased in Finland (this revenue remains), wages are paid to a small workforce (this remains), but profits — often €500M–€2B annually per major facility — are transferred to the parent company through royalty payments and intra-group financing, reducing the Finnish corporate tax base to near zero through established transfer pricing mechanisms.
Aggregate fiscal position 2030–2032 under DC-dominant scenario. If 3–4 GW of industrial capacity is substituted by data centre load (§A.6 Outokumpu-type scenario), the combined fiscal impact is:
| Item | Annual impact | Source |
|---|---|---|
| Interest expenditure | >€3.5B/year | VK-INTEREST trajectory + stress model |
| Defence spending (central government) | €6.5B (2027) → €8.5B (2029) → €11B (2035) | Ministry of Finance / Ministry of Defence projection (Yle/VM 2026); NATO 3% = €8.5B by 2029, NATO 3.5% = €11B by 2035. Increment from current ~€4.5B: +€2–4B/year structurally committed |
| EDP correction requirement | €1.44B/year | SGP 0.5% GDP/year rule |
| Infrastructure maintenance deficit growth | +€52M/year | Väylävirasto TAE 2026 |
| Tax base erosion (DC substitution, 3–4 GW) | −€450M to −€1,400M/year | §A.7 estimation |
| Free investment capacity | Effectively zero | Structural constraint |
A laissez-faire investment regime that welcomes hyperscale data centres without additionality obligations or transfer pricing controls produces a structural fiscal paradox: Finland provides the electricity, the grid infrastructure, the land, and the regulatory stability — while the value added is recorded in Luxembourg or Ireland. The statistical presentation shows rising investment and growing GDP during the construction phase. The operating phase reveals a different picture: low employment intensity, minimal corporate tax contribution, and a grid capacity allocation that forecloses the industrial users who generate 11× more tax revenue per GW consumed. This is not a market failure in the conventional sense — it is the predictable output of a policy framework that measures success by investment volume rather than fiscal and economic integration quality. It is, in other words, a low IQS investment by the metric of WP-018.
The policy correction is not to exclude data centres — it is to require that they finance the system adequacy they consume (additionality obligation) and that transfer pricing rules are applied with sufficient rigour to capture a fair share of operating profits. Neither measure currently exists in Finnish energy or tax law at the required specificity.
