Montenegro’s improving sovereign credit profile has not produced an immediate reduction in its interest bill. Between 2022 and 2025, the country’s average cost of public debt rose from 2.22 per cent to 3.30 per cent, even as its credit rating moved higher and investors became more comfortable with its economic and institutional outlook.
The apparent contradiction reflects the way sovereign borrowing is priced. A credit rating influences the risk premium investors demand from Montenegro, but that premium sits on top of European benchmark interest rates, market liquidity, refinancing pressure, global risk appetite and the maturity of the bonds being issued. A stronger rating can narrow the risk component while the total borrowing cost still rises because the underlying price of money has increased more sharply.
Marko Pešić, head of investment banking at Hipotekarna Banka, has illustrated the effect through Montenegro’s public-debt figures. In 2022, the country carried an average public-debt stock of approximately €4.13bn and paid €91.83mn in interest. By 2025, average debt had expanded to €4.88bn, while annual interest expenditure reached €161.07mn.
The implied average interest rate increased by 1.08 percentage points, or about 49 per cent, despite Montenegro’s sovereign rating improving from the B category to B+ on the Standard & Poor’s scale. Moody’s separately raised the country from B1 to Ba3 in September 2024, its first upgrade in a decade.
Both agencies have since strengthened their assessment of the outlook. S&P affirmed Montenegro at B+ and moved the outlook to positive in February 2026, while Moody’s retained Ba3 and changed its outlook from stable to positive in March.
These actions are favourable, but Montenegro remains below investment grade. Moody’s Ba3 sits three steps below Baa3, the lowest investment-grade category. S&P’s B+ is four steps below BBB-. The country is therefore still classified as a speculative-grade sovereign and remains outside the investment mandate of many conservative pension funds, insurers and institutional fixed-income portfolios.
The distinction matters because an upgrade within speculative grade may improve demand without fundamentally changing the investor universe. The largest repricing often occurs when a sovereign approaches or crosses the investment-grade boundary, allowing its bonds to enter additional indices and become eligible for funds that cannot hold lower-rated debt.
Montenegro is not yet at that point. Its improving rating reduces the premium it would otherwise pay, but it does not remove the liquidity, scale and refinancing discounts attached to a small non-EU sovereign with a concentrated economy and a limited domestic capital market.
The rise in the average cost of debt since 2022 is primarily the legacy of the European interest-rate cycle. At the beginning of that year, the European Central Bank’s deposit rate was still negative. By the end of 2022, the ECB’s main rates had risen sharply as policymakers responded to the inflation shock generated by energy prices, supply-chain disruptions and Russia’s invasion of Ukraine.
Montenegro uses the euro without being a member of the eurozone. This eliminates most currency risk from its public debt, but it also means the country imports the ECB’s monetary conditions without having representation in the central bank’s decision-making process or routine access to all euro-area liquidity facilities.
When euro benchmark rates rise, Montenegro’s new borrowing becomes more expensive even when its own credit fundamentals are improving. Investors price a Montenegrin bond as the relevant euro risk-free or swap rate plus a sovereign spread, term premium, liquidity premium and new-issue concession.
A simplified example explains the mechanism. A sovereign might borrow at a benchmark rate of zero plus a 300-basis-point spread, producing a total yield of 3 per cent. Several years later, a rating improvement might narrow its country spread to 200 basis points, but a benchmark rate of 2.5 per cent would still produce a total yield of 4.5 per cent. The sovereign has become safer relative to the market, yet the absolute cost of borrowing has risen.
This is broadly what happened to Montenegro. The debt portfolio in 2022 contained a large proportion of bonds and loans contracted during the period of exceptionally cheap European money. As those instruments mature, they are replaced by debt issued at the higher rates prevailing after 2022.
The most visible example is Montenegro’s €750mn Eurobond due in December 2027, issued during the pandemic-era market in 2020 with a coupon of 2.875 per cent. That transaction helped the incoming government avoid an immediate funding crisis and locked in historically cheap financing for seven years.
Replacing a 2.875 per cent instrument with a bond priced between 4.5 and 5 per cent would raise annual interest expenditure on the same €750mn principal by approximately €12mn to €16mn. No rating improvement currently within reasonable reach could fully offset the difference between the 2020 interest-rate environment and present market conditions.
Montenegro’s 2024 international bond illustrates the new pricing regime. The government issued $750mn of seven-year notes with a dollar coupon of 7.25 per cent. A cross-currency swap converted the exposure into approximately €687.8mn at an effective euro interest rate of about 5.88 per cent, protecting the state against direct dollar exchange-rate risk.
The order book exceeded $4.7bn, more than six times the amount issued. Such demand showed that Montenegro retained market access and that investors were willing to finance it through a period of substantial refinancing needs. Yet strong demand did not return the cost of funding to the exceptionally low levels available before global monetary tightening.
The structure of the 2024 placement also showed the limitations of Montenegro’s investor base. Investment funds took approximately 92 per cent of the transaction, while banks accounted for about 4 per cent and pension and insurance investors roughly 3 per cent. Geographically, investors from the United States represented 47 per cent, the United Kingdom 29 per cent and continental Europe 22 per cent.
A transaction dominated by asset managers can be highly successful, but it differs from a bond anchored by central banks, insurers and pension funds. Asset managers are generally more sensitive to market valuations, relative yield and changes in global risk appetite. Their demand can disappear more quickly when emerging-market spreads widen.
Conditions improved by the time Montenegro returned to the euro market in March 2025. The government sold a record €850mn seven-year Eurobond with a 4.875 per cent coupon, nearly one percentage point below the euro-equivalent cost of the 2024 dollar transaction.
Investor orders were approximately three times the issue size. The transaction refinanced most of the €820mn in obligations falling due during 2025, including a €500mn Eurobond issued in 2018 with a 3.375 per cent coupon.
This refinancing again increased the annual coupon burden. Replacing €500mn at 3.375 per cent with funding costing 4.875 per cent produces an additional annual interest cost of about €7.5mn on an equivalent principal amount. The maturity was extended to 2032, reducing short-term refinancing risk, but the fiscal price of that extension is a higher coupon.
The 2025 bond has subsequently traded above its issue price. At a market price of around 101.7 per cent of face value in July 2026, its yield was approximately 4.67 per cent, below the original 4.875 per cent coupon. That secondary-market movement indicates some improvement in investor perception and market conditions since issuance.
It also shows where the rating benefit appears first. A sovereign upgrade does not reduce the coupon on fixed-rate debt already outstanding. It can, however, push existing bond prices higher and their yields lower, creating a more favourable reference point for the next transaction.
Montenegro’s total interest expenditure nevertheless continues to rise because the average portfolio cost changes slowly. Sovereign debt is a collection of loans and bonds issued in different years, at different rates and with different maturities. The average cost is determined by the entire stock, not only by the price of the most recent bond.
As older low-coupon obligations mature and are replaced, the higher post-2022 rates gradually feed into the budget. This process can continue even after central banks begin easing monetary policy because refinancing occurs in stages. The government’s interest bill may therefore rise for several years after market yields have peaked.
Debt volume compounds the effect. Average public debt increased by approximately €750mn between 2022 and 2025, from €4.13bn to €4.88bn. Even with an unchanged average interest rate, a larger principal would have produced a higher annual interest expense. Montenegro experienced both a larger debt stock and a higher average rate.
By March 2026, gross public debt had reached approximately €5.13bn, equivalent to about 59.9 per cent of projected GDP. The government expects the ratio to rise temporarily to around 68 per cent of GDP during 2026, largely because it is pre-financing the €750mn Eurobond maturity in 2027 and building a fiscal reserve.
This creates an important distinction between gross and net debt. Issuing new bonds before old ones mature temporarily places both liabilities on the state’s balance sheet, raising gross debt. The borrowed cash remains in government deposits until the maturity is repaid, so the increase in net debt is much smaller.
The government’s medium-term framework projects net public debt at 56.4 per cent of GDP in 2026, compared with the temporarily elevated 68 per cent gross ratio. Once the 2027 Eurobond is redeemed, gross debt should decline, with the government forecasting a ratio of 59.9 per cent by 2029.
Pre-financing carries a cost. The state pays interest on new debt while holding the proceeds in cash or low-risk deposits, which may earn a lower return. This creates negative carry. The strategy is still rational when a large maturity is approaching because it protects the sovereign from being forced to borrow during a market shock, political crisis or period of elevated spreads.
For Montenegro, the insurance value is considerable. The €750mn maturity represents a substantial share of annual economic output and government revenue. Waiting until the final months before repayment would expose the budget to market-timing risk. A sudden rise in European yields or deterioration in regional sentiment could add tens of millions of euros to lifetime debt-service costs.
The 2026 budget allows up to approximately €710mn in funding for debt repayment, capital expenditure and reserve building, with around €383.6mn of obligations scheduled to mature during the year. The larger strategic concern is the 2027 maturity wall, followed by the €500mn 2.55 per cent Eurobond due in 2029 and the swapped dollar bond maturing in 2031.
The 2029 bond will create another step-up challenge. Its coupon of 2.55 per cent was fixed in 2019, when European market rates were extremely low. Refinancing it at anything close to current yields would raise the annual coupon expense materially.
The 2024 and 2025 transactions have already extended part of the maturity profile to 2031 and 2032, reducing the frequency of near-term repayment peaks. This is positive for the sovereign rating because agencies assess not only the debt-to-GDP ratio but also liquidity buffers, maturity concentration, currency exposure and the government’s record of market access.
Montenegro’s debt structure has one notable strength: approximately 99.7 per cent is denominated in euros after accounting for hedging. The country therefore faces almost no direct currency mismatch between government revenue and debt service. This is a major advantage compared with emerging-market sovereigns that borrow in dollars while collecting taxes in a weaker domestic currency.
Euroisation does not eliminate sovereign risk. Montenegro cannot create euros to service its obligations, and its central bank cannot act as a conventional sovereign lender of last resort. Debt service must be financed through taxation, asset sales, deposits, official-sector loans or continued access to capital markets.
Investors consequently pay close attention to fiscal liquidity. A government deposit buffer, even when it temporarily raises gross debt, can strengthen creditworthiness by demonstrating that upcoming obligations are covered. This is one reason rating agencies may view pre-financing more favourably than a simple gross-debt ratio would suggest.
The rating outlooks also reflect Montenegro’s economic growth and EU accession prospects. S&P expects net general-government debt to average around 52 per cent of GDP between 2026 and 2029, below the pre-pandemic level, while the government projects average real growth of approximately 3.1 per cent over the same period.
Montenegro’s progress towards possible EU membership in 2028 is becoming part of the sovereign-credit story. Accession can improve institutions, increase access to European funds, lower political risk and strengthen the banking and regulatory framework. Bond markets may begin pricing part of that convergence before formal membership, provided reforms remain credible.
EU accession is not equivalent to guaranteed euro-area membership or automatic ECB support. Montenegro already uses the euro unilaterally, and entry into the EU would not immediately place its sovereign bonds on the same footing as those of eurozone members. Investors will continue differentiating Montenegro according to its fiscal capacity, institutions and market liquidity.
The country’s economy also remains vulnerable to tourism concentration, external deficits and infrastructure bottlenecks. The current-account deficit widened to 17.1 per cent of GDP in 2024 and remained elevated in 2025, reflecting weak goods exports and heavy dependence on imports, foreign investment and tourism receipts.
Fiscal policy presents another constraint. The government’s medium-term framework envisages a budget deficit of 3.7 per cent of GDP in 2026, narrowing only gradually to 3.2 per cent by 2029. The primary deficit is projected to fall from 1.7 per cent to 0.6 per cent, while the current budget remains in surplus.
The distinction between current and capital expenditure is helpful, but markets still assess whether infrastructure borrowing produces sufficient economic returns. Debt-financed motorway, railway, energy and environmental projects can strengthen future growth when procurement is disciplined and construction delivers on time. Cost overruns, weak project selection and delayed operation instead leave the sovereign with higher debt but little additional revenue capacity.
Montenegro’s small bond market creates a separate liquidity premium. Its international issues are large relative to the domestic economy but small compared with the sovereign curves of major European states. There are fewer maturities, less secondary-market turnover and a narrower investor base. Portfolio managers therefore demand compensation for the risk that bonds may be more difficult to trade during periods of market stress.
A rating upgrade cannot eliminate that structural premium. It can broaden demand incrementally, but a deeper reduction in borrowing costs requires regular issuance, predictable debt-management communication, transparent fiscal reporting and a smoother maturity curve. Montenegro must behave like a repeat sovereign issuer rather than entering the market only when a large repayment is approaching.
Domestic capital-market development could also reduce dependence on international Eurobonds. Local banks have strong liquidity and already hold government securities, but excessive domestic borrowing can crowd out corporate lending and increase the connection between sovereign and banking-sector risk. A balanced programme would use domestic bonds for shorter and medium maturities while preserving access to international investors for longer-term refinancing.
The improvement in Montenegro’s rating has therefore delivered value, even though the interest bill has risen. The relevant comparison is not with the cost of debt issued during the negative-rate era, but with the yield Montenegro would pay today without the rating upgrade, positive outlook and progress towards EU membership.
The 2025 Eurobond cost 4.875 per cent, nearly one percentage point less than the euro-equivalent rate achieved in 2024. Its secondary-market yield later moved down to about 4.67 per cent. Those developments suggest that the sovereign spread and market perception have improved, even as European benchmark rates remain much higher than in 2020–2022.
The next test will be the refinancing of the €750mn 2027 bond. Every reduction of 50 basis points on that amount saves approximately €3.75mn a year, or more than €26mn over a seven-year maturity, before issuance expenses. A full percentage-point improvement would double those savings.
Montenegro’s rating trajectory can therefore produce substantial budget benefits, but only at the point when new debt is priced or variable-rate liabilities reset. It cannot reverse coupons already contracted, and it cannot recreate the near-zero benchmark rates that allowed earlier governments to issue debt at 2.55 to 2.875 per cent.
The country is becoming a better credit at a time when credit itself has become more expensive. Its positive rating outlooks are limiting the increase in sovereign spreads, while the refinancing of old low-cost bonds is pushing the average interest burden higher. The success of debt management will be measured by the premium Montenegro pays above European benchmarks and the maturity risk it removes, rather than by a return to the exceptional borrowing costs of the previous monetary cycle.
