European governments must improve economic growth or reduce borrowing if they want to keep public debt at a sustainable level, the International Monetary Fund has warned. The advice comes as countries face growing costs linked to ageing populations, defence needs, energy changes and pressure on public services.
The IMF expects the eurozone economy to grow slowly in 2026 and 2027. Such growth may make it harder for governments to pay for new commitments while also managing existing debt. Inflation is expected to ease over time, but the cost of borrowing remains an important concern for public budgets.
The fund says many European countries need stronger plans to control spending and improve the way their economies work. It has called for structural reforms and medium-term budget measures that can make public finances more stable. These changes could include removing barriers to business activity, improving productivity and making it easier for companies to invest and expand.
However, the scale of the challenge differs from one country to another. Some governments may need only moderate changes, while others could face much larger adjustments. Cutting spending too quickly can also weaken demand and place pressure on public services, so leaders must decide how to balance short-term needs with long-term stability.
Europe’s ageing population is one of the biggest pressures. As people live longer, governments may need to spend more on pensions and health care. At the same time, defence spending is rising as countries respond to security threats. The shift towards cleaner energy also requires investment in power systems, transport and industry.
The IMF argues that stronger growth would make these costs easier to manage. Better productivity, wider access to markets and investment in innovation could help businesses produce more value and create jobs. Governments may also need to make public spending more efficient instead of relying mainly on tax rises or borrowing.
The warning places fiscal policy at the centre of Europe’s economic debate. Governments want to protect households and support investment, but they must also reassure lenders that their debt can be repaid. If economic growth remains weak, the choices may become harder.
For European leaders, the task is to build economies that can grow while keeping public finances under control. The IMF’s message is that delaying difficult decisions could make later adjustments more painful and leave governments with less room to respond to future crises.
