The public finances of the major eurozone countries will face three challenges in the coming years:

rising defense spending, higher interest payments on existing debt, and unfavorable demographic trends. The resulting additional expenditure is unlikely to be offset by savings elsewhere, meaning that budget deficits and debt ratios will rise significantly. This will lead to louder calls for joint debt issuance, and probably increase pressure on the ECB to ease the burden of the highly indebted member states through lower interest rates and bond purchases.

German public deficit is rising...

As shown by the federal budget for 2025 and the financial planning for the following years presented to the Bundestag this week, the federal government intends to significantly increase its spending and finance this by taking on additional huge amounts of debt. If the plans are implemented as proposed, the deficit ratio would probably be slightly above 4% of GDP in the coming years.

In the end, the shortfall could be even higher. This is because the coalition partners want to reform, i.e. relax, the debt brake again. If they succeed, the coalition will certainly make use of the additional financial leeway this will create, as despite the planned debt splurge, there are considerable gaps in the financial planning for the years from 2027 onwards. One thing is clear: Germany's debt ratio will rise massively in the coming years.

... but the budgets of other eurozone countries are also under pressure

Germany is not alone among the eurozone countries in facing this prospect. The national budgets of the other large eurozone countries will also be confronted in the coming years – to varying degrees – with the burdens that are at least partly responsible for the additional German government debt: higher defense spending, rising interest charges, and unfavorable demographic trends.
