The ECB’s Liquidity Trap: Rate Cuts Will Inflate Assets, Not Wages

The Measurement Crisis: Targeting a Phantom Number

Monetary transmission relies entirely on the credibility of the target. On February 4, 2026, Eurostat revised the Harmonised Index of Consumer Prices (HICP) methodology, altering the weightings for services and housing [1]. This technical shift is macro-critical: the current 1.7% headline inflation rate is calculated on a different basis than the 2.0% target was originally defined.

Comparing the January 2026 print to historical targets without a public recalibration is akin to measuring temperature with a shifted thermometer. The Survey of Professional Forecasters (SPF) currently projects 1.8% inflation for 2026, unchanged from the previous round despite a contraction in the M3 money supply from 5.2% in 2022 to 2.1% in late 2025 [2]. This stagnation in forecasts suggests professionals are not modeling economic fundamentals but are displaying "institutional bias"—anchoring to stability in the absence of trustworthy data.

Unless the ECB explicitly rebases its target to match the new HICP methodology, rate cuts will be interpreted by peripheral banks not as accommodation, but as institutional desperation. A central bank cutting rates to hit a target it cannot consistently measure destroys the very expectations channel it seeks to manipulate.

The "Trilemma of Divergence" Framework

To understand why standard countercyclical policy will misfire, one must map the decoupling of the eurozone economy. We introduce the Trilemma of Divergence, a framework explaining why a single interest rate cannot serve three distinct economic realities.

The disconnect is visible in the data. While financial markets price inflation protection at 2.15%, reflecting capital risks, the real economy faces a monetary contraction. M3 growth of 2.1% is insufficient to support 2% inflation plus trend growth. By cutting rates, the ECB fuels the top row (assets) while the bottom row (wages) suffers from the signal that the economy is broken.

The Inequality Accelerator: r > g in Action

The primary failure mode of the upcoming cuts is distributional. In a regime where the return on capital (r) exceeds economic growth (g)—and SPF forecasts notably peg 2026 growth at a sluggish 1.0–1.2% [3]—monetary easing effectively subsidizes leverage for asset holders.

Transmission lags in the eurozone are regionally asymmetric. Credit impulse data indicates that lending changes in the Core (Germany) impact the real economy within 6 months, whereas peripheral transmission through banking systems in Spain and Portugal takes 12–18 months due to structural capital constraints and higher risk premiums.

Consequently, a rate cut to 1.5% translates into German mortgage rates dropping to near 1%, triggering real estate appreciation. In the periphery, risk premiums keep effective borrowing costs elevated (above 2.2%), preventing the credit expansion needed for business investment. The result is German asset inflation without Portuguese wage inflation. This widens the wealth gap, confirming to peripheral workers that the system is rigged against labor income, further dampening the consumer sentiment required to lift headline inflation.

Counterargument: The Cash-Flow Defense

Proponents of immediate easing, arguing from a neo-Keynesian perspective, contend that the transmission lag is overstated. They argue that rate cuts provide immediate cash-flow relief to households holding variable-rate debt and that the sheer "announcement effect" of a 50-basis-point cut would shock the system out of its lethargy.

Rebuttal: This view ignores the empirical record of recent years. During the 2022–2023 cycle, Portuguese consumption data showed near-zero response to rate signaling in the quarters immediately following policy shifts. The announcement effect collapses when institutional credibility is low. Furthermore, the argument assumes a linearity between rates and spending that breaks down when unemployment expectations are rising. With expectations of structural wage stagnation, households save the windfall from lower debt service rather than spending it—a phenomenon known as "defensive deleveraging." This explains why, despite previous accommodation, household savings rates remain elevated while M3 contracts.

What to Watch

The risks for the next 18 months are not balanced; they are skewed toward a "stagflationary inequality" scenario where asset prices rise while the real economy stagnates.

• Watch the Wage-Price Decoupling: Monitor the spread between the 5y5y inflation swap (currently 2.15%) and negotiated wage growth in the periphery.

  • Prediction: By Q3 2026, this spread will widen by at least 30 basis points as asset expectations rise and wage expectations fall. Confidence: High.

• Watch the Credibility Fallout: Observe if the ECB publishes a retroactive reconciliation of the February 2026 HICP revision.

  • Prediction: If no reconciliation is published by Q4 2026, professional forecaster dispersion (the gap between highest and lowest forecasts) will increase by 20%, signaling a loss of consensus on the target itself. Confidence: Medium-High.

• Watch the Political Backlash: The lagging indicator of this policy failure will be political.

  • Prediction: By mid-2027, polling for anti-euro parties in the periphery will correlate to the widening spread between German real estate appreciation and local wage growth. If core asset inflation exceeds 4% while peripheral wages grow under 1.5%, expect a renewed sovereign debt risk premium crisis. Confidence: Medium.
