Moody’s Ratings affirmed Belgium’s long-term issuer and senior unsecured ratings at Aa3 following a periodic review conducted through a rating committee on October 2 2025. The agency cited the nation’s wealthy innovative economy and advantageous location at the heart of Western Europe as key supporting factors for the rating level. Belgium has shown greater resilience to economic shocks than expected including the 2022 inflation and energy crisis according to the assessment.
The negative outlook reflects risks that the government may not implement sufficient measures to stabilise the public debt burden which Moody’s Ratings identified as the primary challenge. Structural reforms form the core of the current administration’s programme aimed at addressing low employment rates an aging population and growing budget deficits the agency noted. A failure to advance fiscal consolidation could lead to further pressure on the rating in coming years.
Eurostat data places Belgium’s government debt at 107.9 percent of GDP at the end of 2025 up from 103.9 percent a year earlier with the country ranking among the highest in the European Union.[[1]](https://ec.europa.eu/eurostat/web/products-euro-indicators/w/2-22042026-ap) The general government deficit widened to 5.2 percent of GDP in 2025 from 4.4 percent in 2024 according to the National Bank of Belgium. IMF staff projections indicate the debt ratio could climb above 121 percent by 2031 without additional corrective actions.[[2]](https://www.elibrary.imf.org/view/journals/002/2026/049/article-A000-en.xml)
Prime Minister Bart De Wever welcomed the decision stating that the reforms already implemented are appreciated and grant a respite. In comments reported across Belgian media De Wever added that new efforts are necessary to further improve the budget balance by the end of the legislative term. The government has pointed to pension adjustments and limits on unemployment benefits as evidence of progress in fiscal responsibility.
Moody’s Ratings highlighted that coordination among different levels of government on budgetary policies could yield positive results if strengthened alongside labour market reforms to boost employment. The assessment also flagged weakening competitiveness from recent wage increases and high energy costs as potential drags on growth. Geopolitical risks were listed among factors that could weigh on Belgium’s credit profile in the period ahead.
Fitch Ratings downgraded Belgium’s sovereign rating earlier in 2025 while other major agencies continue to monitor the fiscal trajectory closely. Belgium’s rating remains in the high-grade category signifying very low credit risk although positioned at the lower end of the Aa range. The affirmation arrives as authorities prepare the 2026 budget with a focus on multiyear consolidation plans to ease market concerns over borrowing costs.
