In the major advanced economies, public deficits remain high, particularly in the United States, the United Kingdom and France. Interest expenditures are expected to rise in countries where they are currently low – Germany, Japan and France – and stabilise at a high level in countries where they are currently higher – Spain and Italy – without, however, increasing. By 2030, according to our forecasts, the dynamics of the public debt-to-GDP ratio would reflect differences in public deficit scenarios.
The US primary deficit is expected to narrow in 2025 and stabilise at around 1.0–1.5% of GDP in the coming years thanks to higher customs revenues.
Germany's primary deficit is expected to widen over the next two years as a result of the new fiscal strategy, before gradually narrowing between now and 2030.
Despite consolidation, which is set to continue from 2026 until the end of the decade, the primary deficit will remain worse than the stabilising balance. Public debt will therefore increase.
Until 2027, nominal growth (3.2% on average) is expected to remain higher than the apparent interest rate (3.1%) due to an acceleration in real growth (0.9%).
Spain is expected to generate primary surpluses from 2026 onwards.
The primary budget balance has gradually recovered post-COVID, mainly supported by improved growth, but remains high compared to the rest of Europe.
Japan's primary deficit is expected to narrow in 2025 but is likely to increase again to around 2% of GDP in the coming years due to upward pressure on public spending.
