OECD nations are facing a significant increase in sovereign debt interest burdens, which have risen to 3.3 percent of their collective GDP. In major economies like the United States, United Kingdom, and France, interest payments have exceeded defense spending, potentially limiting funding for healthcare, infrastructure, and energy security.

On a national level, Estonia has seen its public debt reach 11.3 billion euros, or 26.1 percent of its GDP. This represents a fivefold increase since 2015, driven largely by rising defense, security, and social protection costs. Projections suggest Estonia’s debt-to-GDP ratio could approach 40 percent by the end of the decade as interest payments continue to climb.
