Serbia completed a €3bn equivalent international bond transaction in spring 2026, using the proceeds to refinance upcoming obligations, extend debt maturities and expand the investor base supporting government financing. The multi-tranche issuance reduced repayment pressure in the near term, although the yields paid reflected a higher cost of external borrowing compared with the period before global interest rates increased.
Investor demand exceeded €8bn, resulting in an overall subscription ratio above 2.6 times the amount issued. The transaction combined euro-denominated bonds, a dollar-denominated issue converted through swaps, and a green bond component.
Three-tranche issuance combines conventional and green financing
The government issued a €1bn conventional eurobond maturing in 2031, with a 4.25 per cent coupon and an issuance yield of 4.397 per cent. A second tranche involved a $1.25bn bond due in 2036, carrying a 5.5 per cent coupon and a yield of 5.814 per cent. After the dollar proceeds and related liabilities were swapped into euros, the effective euro coupon was approximately 4.66 per cent, reducing Serbia’s exposure to dollar exchange-rate movements.
The third instrument was a €900mn green bond maturing in 2038, issued with a 4.875 per cent coupon and a yield of 5.173 per cent. Funds from the green bond are intended for financing or refinancing eligible environmental and social spending under Serbia’s sovereign sustainable-finance framework. Part of the proceeds was used to repurchase €870.8mn of an existing eurobond scheduled to mature in 2027. Following the tender, the outstanding amount of that bond declined to approximately €1.13bn, shifting a significant portion of repayment obligations into later years.
Debt structure remains below European reference levels
The transaction reduced concentration around the 2027 refinancing period, created additional reference points for Serbia’s sovereign yield curve and combined several financing instruments within one international market operation. At the end of May 2026, central government debt stood at €41.14bn, equal to 43.7 per cent of GDP. General government debt, including relevant local government obligations, amounted to €41.44bn, or 44 per cent of GDP.
Serbia’s debt ratio remains below pandemic-era levels and below the Maastricht reference threshold of 60 per cent. Nominal economic growth and relative stability of the dinar against the euro have also supported the decline in the debt-to-GDP ratio. The composition of debt, however, continues to show significant foreign-currency exposure. Around 79.7 per cent of central government debt is denominated in foreign currencies. The euro represents 62.9 per cent, the dinar 20.3 per cent, the dollar 11.3 per cent, and special drawing rights 5.3 per cent of the total debt structure. Currency swaps reduce part of the dollar-related risk, but the overall debt stock remains sensitive to movements between the dinar and the euro.
Interest exposure and domestic debt market capacity
Approximately 67.2 per cent of Serbia’s debt carries fixed interest rates, while 32.8 per cent is linked to variable rates. Within the variable-rate portion, 72 per cent is tied to Euribor, 16.3 per cent to special drawing rights-related rates, and 11.6 per cent to Belibor. Lower European interest rates could gradually reduce debt-servicing costs, while renewed inflation or higher rates would increase financing pressure.
The domestic government securities market remains an important but relatively limited source of funding. At the end of May, outstanding securities included around RSD788bn of dinar-denominated bonds and €1.74bn of euro-denominated domestic bonds. Non-resident investors held RSD97.8bn, representing 12.4 per cent of dinar securities. A larger domestic institutional investor base could allow Serbia to issue longer-term dinar debt and reduce dependence on international capital markets. For now, international bonds, multilateral financing and project-related borrowing remain key components of the sovereign funding structure.
Fiscal balance remains central to debt management
The government’s ability to use the refinancing space created by the bond transaction will depend on fiscal execution. General government recorded a RSD106.5bn deficit in January–May 2026, as expenditure increased 12.5 per cent year on year, exceeding revenue growth of 9.9 per cent.
Higher capital spending can contribute to future economic capacity, but increases in current expenditure or delays and cost overruns on projects could raise debt without generating equivalent improvements in productive output. The bond operation lowered immediate refinancing risks and maintained Serbia’s access to international capital markets. The long-term impact will depend on whether the borrowed funds support infrastructure, productivity improvements and export capacity capable of offsetting financing costs of approximately 4.3 per cent to 4.9 per cent in euro terms.
