IMF Warns Inflation Battle Is Not Over as Services Prices Stay Sticky

Quantitative Assessment and Model-Based Projections

The IMF's Global Projection Model simulations indicate that services inflation in advanced economies will not return to pre-pandemic norms until late 2027 under a baseline scenario of gradual, sequential rate cuts beginning in H2 2026. Under an "early easing" scenario where central banks cut by 100 bps through end-2026, services inflation rebounds to 3.8% in 2027 — requiring a reversal of the easing cycle. The model identifies wage growth as the single most important leading indicator of services inflation persistence, with a 6–9 month lag.

The note also examines second-round effects through inflation expectations. In economies where 2-year ahead inflation expectations have become de-anchored above the 2% target — notably the United Kingdom and several eurozone periphery members — the IMF estimates that the disinflation cost in terms of output loss is 30–40% higher than in economies where expectations remain well-anchored. This finding underscores the value of credible monetary frameworks and clear central bank communication.

For emerging markets, the IMF models the fiscal risk premium in bond markets as a function of the primary balance trajectory and debt levels. Countries maintaining primary surpluses of 1% of GDP or above see lower sovereign spreads and more stable exchange rates — validating the case for continued fiscal consolidation even in the face of short-run growth costs.
