The International Monetary Fund warned on Friday, October 16, that European governments must accelerate economic growth, restrain borrowing or combine both approaches to keep public debt sustainable as ageing populations and higher spending needs strain budgets.
In its latest assessment of Europe’s economy, the IMF forecast growth in the euro area of 1.1% in 2026 and 1.2% in 2027. It projected inflation in the currency union at 3.1% this year, easing to 2.8% in 2027 and 2.2% in 2028.
The scale of the adjustment
The Fund estimated that around three-quarters of European countries would need structural reforms alongside fiscal consolidation averaging about 3.5% of gross domestic product over the medium term to keep debt on a sustainable path.
That figure is not a proposal for an immediate 3.5% spending cut in every country. It describes an average medium-term budget adjustment alongside reforms to strengthen economic performance. Requirements vary substantially between national economies.
By comparison, fiscal adjustments outlined in EU countries’ medium-term plans averaged roughly 2% of GDP, below what the IMF considers necessary in some cases. Around one-quarter of European countries could require adjustments exceeding 5% of GDP, a scale the Fund described as historically difficult to deliver.
Debt projections and long-term pressures
European Commission projections cited in the assessment showed euro-area public debt rising from 88.7% of GDP in 2025 to 90.2% in 2026 and 91.2% in 2027. For the wider European Union, debt was projected to rise from 82.8% in 2025 to 85.3% by 2027.
The IMF cautioned that, without policy changes, public debt in the average European economy could grow to as much as twice its present level over the longer term. The warning reflects mounting costs associated with ageing societies, defence commitments and the transition to cleaner energy.
The Fund’s European department has emphasised that postponing fiscal action tends to make the eventual adjustment harder. It also warned that budget consolidation already planned by governments may be difficult to achieve in full.
Why productivity matters
The IMF identified weak productivity as a central obstacle to stronger European growth. It urged governments to reduce barriers within the EU’s single market, support innovation and help businesses expand across national borders.
It also backed measures to diversify supply chains, invest in clean energy and improve the region’s competitiveness. Faster economic growth would make existing debt easier to service relative to the size of the economy, reducing the burden of fiscal adjustment.
For European policymakers, the challenge is to balance debt restraint with investments that support long-term growth. The IMF’s message is that neither borrowing indefinitely nor relying on growth without reform offers a dependable solution.
