Belgium Raises €3.5 Billion Through Treasury Certificate Auction
BRUSSELS — Belgium has raised approximately €3.501 billion through its latest auction of Treasury certificates, providing the federal government with fresh short-term financing as it manages its public finances.

The Belgian Debt Agency confirmed that bids accepted during the September 8 auction were distributed across several Treasury certificate lines. The operation represents another regular step in Belgium’s management of its short-term government financing needs.
Treasury certificates are short-term Belgian government securities used to help finance the state and manage cash requirements. Investors purchase the securities, providing funds to the government for a specified period before repayment.
The latest auction comes shortly after Belgium reported that its federal government debt had reached approximately €578.169 billion at the end of August 2026. The figure represented an increase of about €3.18 billion compared with July.
On a net basis, after accounting for financial placements and securities held in the Treasury’s portfolio, federal government debt stood at approximately €553.69 billion at the end of August.
Belgium’s latest financing operation therefore comes against the backdrop of a substantial public-debt burden. Regular auctions allow the Treasury to maintain access to funding while managing the maturity structure and refinancing requirements of government debt.
The Belgian Debt Agency is responsible for managing the federal government’s debt portfolio and conducting operations in domestic and international financial markets. Its activities include issuing government securities, managing refinancing risks and monitoring borrowing costs.
The August debt figures also showed that Belgium’s average government-debt maturity stood at approximately 10.17 years, while the average interest rate on debt instruments increased to around 2.24%.
The latest Treasury certificate auction highlights the continued importance of short-term financing instruments within Belgium’s broader debt-management strategy.
With European governments facing pressure to balance public investment, economic growth and debt sustainability, Belgium’s borrowing operations will remain closely watched by financial markets.
The government’s ability to secure financing at manageable costs will be an important factor in determining how Belgium manages its public finances in the months ahead.
