Citable research brief

Core conclusion · Tlines extraction

ING's debt sustainability dashboard assesses fiscal health across developed markets amid rising bond yields, highlighting that high debt ratios alone are misleading. Key findings include the US, UK, and France needing austerity to stabilize debt, while Germany and France require ~2% of GDP in measures. The US fiscal position is vulnerable due to policy actions, the UK's outlook is better than assumed, and eurozone divergence poses risks. r-g dynamics and debt ownership are critical factors.

Key arguments

Debt-to-GDP ratios are a simplistic measure; primary deficits, interest rates, and bond ownership are more critical for sustainability.
The US, UK, and France need austerity measures to stabilize or lower government debt ratios.
The US fiscal position has worsened under current policies, with OBBBA adding $2.8tr to national debt by 2034.
Germany and France require fiscal consolidation worth about 2% of GDP to keep debt ratios stable.
The UK's fiscal backdrop is better than commonly assumed, with an ongoing fiscal consolidation due to tax threshold freezes.
Eurozone divergence could re-emerge as a theme, and differentiated bond markets will test the ECB's willingness to restart asset purchases.

Key numbers

US interest costs as % of GDP: nearly 5%
Germany interest costs as % of GDP: about 1.5%
OBBBA net debt increase by 2034: $2.8 trillion
French and German fiscal consolidation needed: around 2% of GDP
UK fiscal deficit 2025: around 5%

Main risks

Rising interest rates could make sovereign debt dynamics unsustainable, especially for high-debt countries.
Lack of political will for austerity in the US could lead to further fiscal deterioration.
Eurozone divergence may test the ECB's willingness to restart asset purchases, potentially leading to market stress.
UK's favorable fiscal projections are susceptible to change with upcoming political pressures.

Corresponding source evidence

At current levels, interest rates do not pose a solvency issue for governments. For most countries, the real 10y interest rate is still below real GDP growth. However, many countries (US, UK and France) do need austerity measures to at least stabilise government debt ratios. · medium-term
President Donald Trump’s One Big Beautiful Bill Act (OBBBA) did include over $1tr of healthcare spending cuts for the coming decade, but the permanent extension and expansion of tax cuts and more spending on other areas, including border security, led the Congressional Budget Office to conclude that OBBBA will in fact add $2.8tr to the national debt by 2034. · long-term
With France, Italy, Spain, Belgium and Greece, five out of 21 member states have debt-to-GDP ratios of above 100%. While the former periphery countries have built up fiscal cushions, even allowing for some slippage, France and Germany would currently need austerity measures worth some 2% of GDP to keep debt ratios stable. · medium-term

Conditions / invalidation

If sovereign woes return politically.
If eurozone divergence worsens.
If fiscal policies are not addressed.
