Belgium’s general-government gross debt stood at €692.461 billion at the end of 2025, equal to 107.9% of GDP. The figure covers the whole general-government sector under the European Maastricht debt definition — not only the Belgian federal government.
The short answer
Eurostat reported Belgian government debt of €692.461 billion at the end of 2025. Measured against the size of the Belgian economy, that was 107.9% of GDP.
The figures come from Eurostat’s first 2026 notification under the Excessive Deficit Procedure, published on 22 April 2026. The data are reported under the ESA 2010 system of national accounts. Eurostat reported no reservations on Member State data and made no amendments to them in this notification.
| Year | Government debt | Debt as % of GDP |
|---|---|---|
| 2022 | €580.354bn | 103.3% |
| 2023 | €617.175bn | 102.5% |
| 2024 | €644.199bn | 103.9% |
| 2025 | €692.461bn | 107.9% |
Both the euro amount and the debt-to-GDP ratio were therefore higher at the end of 2025 than at the end of 2024. But understanding the figure requires being precise about what Eurostat means by government debt.
What does €692.461 billion actually measure?
The official measure used here is usually called Maastricht debt or EDP debt. Eurostat defines it as the consolidated gross debt of the whole general-government sector outstanding at the end of the year, measured at nominal value.
Several parts of that definition matter.
- Gross means financial assets are not simply deducted to produce a net-debt figure.
- Consolidated means relevant liabilities between units inside general government are removed rather than counted on both sides.
- At the end of the year means this is a stock measured at a point in time. It is not the amount government spent during 2025.
- General government is wider than Belgium’s federal government. Under the European statistical framework it includes central government, state government, local government and social-security funds.
That institutional perimeter is particularly important in Belgium, where several levels of government have substantial fiscal responsibilities. See what counts as Belgian government for the perimeter distinction.
What is included in Maastricht debt?
The measure covers liabilities in three main ESA financial-instrument categories:
- currency and deposits;
- debt securities;
- loans.
It therefore does not mean “every liability associated with the Belgian public sector.” Eurostat notes, for example, that trade credits and advances are complementary government liabilities but are not part of EDP debt.
This is why apparently similar figures from different official sources can legitimately differ: they may describe different institutional perimeters, instruments, valuation rules or measurement concepts.
What this does not mean
- federal-government debt alone;
- Belgium’s annual government spending;
- Belgium’s annual budget deficit;
- net government debt after subtracting assets;
- every liability of every publicly controlled organisation;
- a continuously updated real-time debt figure.
Debt is a stock; the deficit is a flow
Debt and deficit are especially easy to confuse. Debt is a stock: an amount outstanding at a particular point in time. The government deficit is a flow over a period.
Eurostat reported Belgium’s 2025 general-government deficit separately at 5.2% of GDP. The two measures are connected economically, but they are not interchangeable.
Why the distinction matters
A statement such as “Belgium owes €692 billion” sounds simple, but it hides the measurement framework that makes the number meaningful.
Before comparing that figure with another Belgian number — or with another country — the useful questions are:
- Which government perimeter is being measured?
- Is the figure gross or net?
- What liabilities are included?
- What date does it describe?
- Which statistical release or vintage is being used?
Without those answers, two correctly reported numbers can appear to contradict one another when they are actually measuring different things. See why two official Belgian government numbers can both be correct.
