The cost of government borrowing across the eurozone is changing, challenging the traditional distinction between countries considered financially strong and those viewed as higher-risk borrowers.

Belgium is now paying borrowing costs close to Greece, while France has faced higher ten-year bond yields than Italy.

Government Bond Yields Reveal Changing Investor Confidence

Government bond yields represent the return investors demand for lending money to a country. When yields rise, governments generally face higher costs when issuing new debt or refinancing maturing obligations. Lower yields can indicate stronger demand for a country's bonds and greater confidence in its ability to manage public finances.

In October 2026, Belgium's ten-year borrowing yield reached approximately 4.29%, close to Greece's 4.35%. France also faced higher borrowing costs than Italy, illustrating how investor assessments have evolved. These developments show that national debt levels alone do not determine borrowing costs. Investors also consider budget deficits, economic growth, refinancing requirements and the government's ability to maintain sustainable public finances.

Greece Improves Its Financial Position

Greece has made considerable progress in strengthening its public finances over the past decade. Its budget recorded a surplus equivalent to 1.7% of gross domestic product (GDP) in 2025, while its debt-to-GDP ratio declined significantly.

Improved tax collection, more disciplined budget management and longer debt maturities have helped strengthen the country's financial position. Longer maturities reduce the need to refinance large amounts of debt at once, helping governments manage exposure to changing interest rates.

Belgium and France Face Greater Financing Pressure

Belgium's financial position has become more challenging. Its budget deficit reached 5.2% of GDP in 2025, while public debt exceeded 109% of GDP during the first quarter of 2026. Higher borrowing requirements can increase the amount of debt that must be financed through bond markets.

France faces a separate but related challenge. Its public debt reached approximately €3.6 trillion, equivalent to around 119% of GDP. Government spending also represents a large share of national economic output, making expenditure management an important factor in long-term fiscal sustainability.

The French Treasury planned to issue €340 billion in medium- and long-term bonds in 2027, a record amount. Part of this funding will replace existing debt reaching maturity, rather than finance entirely new spending. As older bonds are refinanced at higher interest rates, government interest expenses can increase. France's projected annual debt interest bill was expected to rise from €62.6 billion in 2026 to €72.9 billion in 2027.

Rising Interest Rates Increase Budget Risks

Higher borrowing costs can gradually place pressure on public budgets. Governments must allocate more revenue to interest payments, potentially leaving fewer resources for infrastructure, education, healthcare and other public services. The timing of debt maturities is particularly important. When a large proportion of government bonds must be refinanced within a short period, changes in market interest rates can affect public finances more quickly.

Germany also planned substantial borrowing to support infrastructure and other investment priorities. This demonstrates that high bond issuance does not automatically indicate financial weakness. The purpose of borrowing, the country's growth prospects and its capacity to service debt all influence investor assessments.

Expert Insight

Ken Egan, Head of European Sovereign Credit at KBRA, explained how improvements in fiscal management have supported countries that previously faced higher borrowing costs. He stated: “That has helped smooth refinancing risks and put debt on a much firmer path than 10 or 15 years ago.”

Europe's government borrowing landscape is evolving as investors reassess national debt sustainability and financing risks. Greece has benefited from stronger fiscal management, while Belgium and France face greater pressure from deficits, debt levels and refinancing costs.

The changing yield environment demonstrates that public debt must be assessed through more than its total size. Budget discipline, economic growth, debt maturity structures and the cost of servicing existing obligations all influence investor confidence. For European governments, maintaining sustainable finances will remain essential to controlling borrowing expenses and preserving room for future investment.
