Serbia’s headline public-debt ratio remains comparatively restrained, but the composition of that debt is moving in a less favourable direction. During the first quarter of 2026, the share of liabilities denominated in dinars fell 1.4 percentage points to 21.1 per cent, extending a retreat from the local-currency funding strategy pursued since 2012.
The movement was driven by two almost offsetting transactions. Dinar liabilities declined by RSD65 billion, principally because government securities matured without being fully replaced. Foreign-currency debt increased by RSD71.2 billion, largely through loans from international financial institutions, including borrowing associated with military-equipment procurement.
Total public debt consequently increased by only RSD6.2 billion during the quarter, or about 0.1 per cent, to RSD4.62 trillion at 31 March. This was equivalent to 41.7 per cent of estimated GDP, leaving the sovereign with considerably more fiscal room than many European borrowers.
The small change in the total, however, obscures the balance-sheet shift underneath it. Foreign-currency liabilities reached RSD3.646 trillion, or €31.06 billion, representing almost 79 per cent of public debt. The euro alone accounted for 61 per cent of the total, after increasing by €582 million during the quarter.
Serbia has therefore reduced the quantity of debt over which its own monetary institutions have direct currency control. Dinar bonds can be refinanced domestically and, in an extreme liquidity event, supported by the National Bank of Serbia. Euro debt must ultimately be serviced from tax receipts converted into foreign currency, export earnings, reserves or fresh access to international markets.
That distinction has been partly concealed by the dinar’s prolonged stability against the euro. The National Bank has maintained a tightly managed exchange rate, limiting the valuation changes that would otherwise appear in the debt stock. Stable trading does not eliminate the exposure; it transfers greater importance to foreign-exchange reserves, capital inflows and confidence in the central bank’s intervention capacity.
At the March balance-sheet position, an illustrative 5 per cent depreciation of the dinar would increase the domestic-currency value of foreign-currency debt by approximately RSD182 billion, before considering any inflation, growth or hedging effects. On the first-quarter GDP denominator, that would mechanically add roughly 1.6 percentage points to the debt ratio. A 10 per cent adjustment would double the effect to about RSD365 billion and 3.3 percentage points of GDP.
The domestic bond market is being allowed to contract
The decline in dinar debt resulted chiefly from the government’s decision not to replace a large maturing bond in full. A RSD150 billion seven-year security matured during the first quarter, while the state sold approximately RSD70.2 billion of five-year bonds and RSD11.6 billion of 10½-year paper.
The outstanding volume of dinar securities therefore fell by RSD68.2 billion. Domestic euro-denominated securities moved in the opposite direction, increasing by approximately RSD9.7 billion, or €80.6 million.
The government sold €200 million of 15-year euro securities, while €144.3 million of the same maturity was redeemed. Restitution bonds added a further modest amount. Overall debt raised through securities on the domestic market declined by RSD58.4 billion to RSD1.026 trillion.
Dinar instruments still represented 76.6 per cent of the government-security portfolio, but this share fell 2.2 percentage points during the quarter. The difference between that relatively high proportion and the dinar’s 21.1 per cent share of total public debt reflects the importance of external loans and international bonds in Serbia’s wider funding structure.
This matters beyond sovereign accounting. Regular dinar issuance creates the benchmark yield curve used to price corporate bonds, infrastructure finance, bank lending and long-term institutional assets. A shrinking stock reduces secondary-market liquidity and leaves banks, insurers and investment funds with fewer domestic fixed-income instruments of sufficient size and duration.
The Public Debt Administration has announced no dinar government-bond auctions for the third quarter of 2026. That may reduce short-term interest expenditure and prevent the sovereign from crowding out private borrowers, but it also interrupts the development of the local capital market. A domestic market becomes resilient through consistent issuance across cycles, not only when its pricing is cheaper than foreign borrowing.
The government faces a genuine cost trade-off. Dinar securities generally carry higher nominal yields because the National Bank’s benchmark rate remains 5.75 per cent and investors require compensation for local inflation and currency risk. Euro borrowing can initially appear cheaper. Yet the lower coupon is obtained partly by transferring exchange-rate and external-refinancing risk from investors to the state.
Serbia’s dinarisation strategy initially delivered substantial progress. The local-currency share of public debt increased from 19.1 per cent in 2012 to 30.5 per cent in 2020. It has since fallen in every year, returning to 21.1 per cent by March 2026. More than three-quarters of the improvement achieved during the earlier period has now been reversed.
International issuance accelerates after the first-quarter reporting date
The March data also understate the subsequent increase in both the size and foreign-currency concentration of the debt stock.
On 28 April, Serbia completed its largest international bond transaction, raising the equivalent of approximately €3 billion through three tranches in two currencies. The package comprised €1 billion of five-year bonds carrying a 4.25 per cent coupon, €900 million of 12-year green bonds with a 4.875 per cent coupon and $1.25 billion of ten-year securities with a 5.5 per cent dollar coupon.
The dollar exposure was swapped into euros, producing an effective euro funding cost of approximately 4.66 per cent for that tranche. The hedge prevents the original dollar liability from introducing a second major currency mismatch, but it reinforces the concentration of Serbia’s sovereign balance sheet in euros.
Investor orders exceeded €8 billion, indicating that Serbia retains meaningful access to international capital. About €870.8 million of the proceeds was used to repurchase part of a bond due in May 2027. That transaction reduced the immediate refinancing requirement and extended the maturity profile, a legitimate liability-management benefit.
Refinancing an existing bond does not represent equivalent net new borrowing. After the repurchase, however, the April transaction still provided slightly more than €2.1 billion of additional gross funding, before other redemptions, issuance costs and cash-management movements.
Serbia returned to the market in July with a further €500 million six-year private placement. The bonds mature on 20 July 2032, carry a 4.75 per cent coupon and were sold below par at 98.666 per cent, producing an effective yield of 5.013 per cent. The proceeds are designated for modernisation of the defence system, including military equipment and associated technologies.
Because the July bonds were privately placed with preselected institutional investors, the transaction offered less public price discovery than the April syndicated issue. The final yield is known, but the size and composition of the order book, the identity of the purchasers and the competitive pressure during pricing have not been disclosed.
The state will receive approximately €493.3 million before expenses but must repay the full €500 million principal. Annual coupons amount to €23.75 million, or €142.5 million over the six-year life of the security. The placement therefore adds a visible recurring cost as well as another bullet repayment to Serbia’s 2032 maturity schedule.
Preliminary Public Debt Administration figures put public debt at approximately RSD4.851 trillion, or €41.3 billion, on 14 July, before settlement of the latest transaction. That was equivalent to roughly 44.4 per cent of GDP, higher than the 41.7 per cent recorded at the end of March but still below conventional European risk thresholds.
The direction is nevertheless important. Serbia is no longer merely refinancing old foreign-currency obligations while reducing the debt ratio. It is using international borrowing to finance green infrastructure, general capital expenditure and defence procurement during a period of unusually high public investment.
Military procurement creates an asset-liability matching question
Borrowing in foreign currency for imported defence equipment can have a rational matching logic. If contracts with overseas suppliers are denominated in euros, raising euro finance avoids converting a large dinar bond issue into foreign currency immediately and reduces short-term transaction risk.
The quality of that match depends on maturity and transparency. Military equipment may provide services over several decades, while the private-placement bond must be refinanced or repaid after six years. Unlike a toll road, railway concession or electricity asset, defence expenditure does not generate a dedicated commercial revenue stream with which to service the debt.
Repayment must therefore come from general taxation or new borrowing. The financing remains manageable at the present debt ratio, but its return cannot be assessed through project cash flow. Investors instead have to consider the effect on the budget deficit, annual interest expenditure and Serbia’s concentration of maturities.
External loans tied to equipment purchases may contain competitive rates, extended grace periods or export-credit support. They may also contain supplier restrictions, sovereign guarantees and conditions that are difficult to compare with publicly auctioned bonds. The currency denomination alone does not reveal whether the financing is economical.
The broader issue is that Serbia’s ambitious capital-investment programme is colliding with the limits of the domestic funding market. The country plans extensive spending on roads, railways, energy, the Belgrade metro, Expo 2027 and defence. International markets can supply the required volume more quickly than Serbia’s local investor base, but doing so builds a sovereign balance sheet whose stability increasingly depends on continued euro access.
A low debt ratio does not remove refinancing risk
Serbia enters this borrowing cycle from a relatively strong headline position. Debt below 45 per cent of GDP provides a substantial buffer against the Maastricht reference level of 60 per cent and against the materially higher ratios carried by many EU members. Government cash holdings and foreign-exchange reserves also reduce the probability that one isolated maturity produces a liquidity crisis.
The country’s credit ratings show the remaining division in investor assessment. S&P Global Ratings places Serbia at BBB-minus with a stable outlook, while Fitch rates it BB-plus with a positive outlook and Moody’s assigns Ba2 with a stable outlook. Serbia has therefore entered investment-grade territory with one major agency but remains speculative-grade with the other two.
That split helps explain borrowing costs around 4.25–5 per cent in euros. Investors recognise declining debt ratios, macroeconomic resilience and strong market access, but continue to price institutional risk, external deficits, geopolitical exposure and the execution demands of a large state-investment programme.
The financing burden will become more visible through interest expenditure. A sovereign can maintain a stable debt-to-GDP ratio while its cash interest bill rises if inexpensive legacy debt is replaced by bonds carrying coupons near 5 per cent. The effect is gradual because only part of the portfolio refinances each year, but it accumulates as newer securities replace older liabilities.
Reliance on foreign investors also makes Serbia more exposed to conditions it cannot control. A change in eurozone rates, regional risk appetite or emerging-market fund flows can raise the cost of a new Serbian issue even if domestic fiscal performance is unchanged. Local-currency financing would not remove market discipline, but it would diversify the investor base and reduce the direct exchange-rate sensitivity of the debt stock.
The sovereign’s present position is therefore one of composition risk rather than immediate solvency stress. Public debt remains moderate, international demand remains available and the April refinancing reduced a near-term maturity. At the same time, the dinar share is approaching its 2012 starting point, the domestic yield curve is losing issuance, and new defence and infrastructure obligations are being concentrated in euros.
The fiscal buffer gives Serbia time to rebuild local-currency funding. Allowing the dinar market to contract further would make the country’s strong headline debt ratio increasingly dependent on a stable exchange rate and uninterrupted access to foreign capital—the two variables over which a small open economy has the least permanent control.
