Montenegro’s public debt has expanded significantly over the past two decades, even as economic growth and higher nominal GDP have reduced the debt burden relative to the size of the economy. Nominal public debt rose from approximately €898 million in 2006 to about €5.19 billion in 2025, with external public debt reaching close to €4.85 billion.
At the same time, the public-debt-to-GDP ratio declined to approximately 63.5% in 2025, compared with a pandemic-era peak of around 106.4%. Economic growth, inflation and the expansion of nominal GDP contributed to the improvement in the ratio despite the continued increase in the absolute debt stock. Montenegro’s fiscal structure remains strongly dependent on consumption, while pensions, healthcare, social transfers and public-sector salaries have increased the share of expenditure that is difficult to reduce. This combination leaves public revenues closely linked to tourism, imports, household consumption and external economic conditions.
VAT remains central to government revenue
Value-added tax represents a key component of Montenegro’s revenue system, reflecting the country’s dependence on imports and the importance of tourism. Imports generate customs and VAT receipts, while spending by tourists and domestic households provides additional consumption-tax revenue. Strong tourism seasons can therefore produce substantial fiscal inflows. The structure also means that government revenue is closely tied to consumption rather than being based predominantly on a broad domestic productive and export economy.
Higher fiscal revenue generated by rising industrial production, corporate earnings and high-value exports would have a different economic foundation from revenue increases driven by greater purchases of imported goods and services. Montenegro continues to record a substantial merchandise trade deficit, reflecting limited domestic manufacturing capacity and a high dependence on imports. Those imports nevertheless provide significant VAT and related fiscal revenue.
Mandatory expenditure limits fiscal flexibility
On the expenditure side, pensions, healthcare, social transfers and public-sector wages represent major government commitments. Once these obligations expand, reducing them becomes more difficult. Capital projects can be postponed when public finances come under pressure, whereas reductions in pensions, salaries and social entitlements are considerably more difficult to implement.
Montenegro therefore has a higher recurring expenditure base that must be supported by continuing revenue collection. A slowdown in tourism, weaker domestic consumption or a sharp moderation in inflation could reduce the growth of nominal VAT receipts while many expenditure commitments remained in place. The resulting fiscal pressure would primarily concern the government’s room for manoeuvre rather than necessarily representing an immediate debt crisis.
Growth and borrowing will shape debt sustainability
The reduction in the debt ratio from more than 100% of GDP during the pandemic to approximately 63.5% illustrates the effect that economic recovery can have on Montenegro’s fiscal indicators. Maintaining further improvements becomes more demanding as the debt ratio declines.
Montenegro continues to face refinancing requirements, while infrastructure development will require additional financing. Road construction, rail modernisation, electricity networks, water and wastewater infrastructure, and EU-related environmental investments all require fiscal resources.
The economic use of new borrowing will therefore remain important. Financing infrastructure that increases productivity, attracts investment or removes economic bottlenecks can strengthen the economy’s capacity to service debt. Borrowing directed toward recurring expenditure has a different effect because it does not create the same additional productive capacity. The issue becomes particularly relevant as Montenegro moves toward EU membership and seeks to accelerate investment through national budgets, EU grants and financing from the European Investment Bank (EIB), European Bank for Reconstruction and Development (EBRD) and other international lender Combining grants with concessional and commercial financing can enable infrastructure projects to proceed without placing their entire financing requirement on sovereign borrowing.
Productive sectors could broaden the revenue base
A broader productive economy would reduce the dependence of public finances on consumption. Tourism remains Montenegro’s dominant private-sector engine, while energy, logistics, technology, agriculture, manufacturing and professional services could increase the contribution of investment, employment and exports to economic activity.
Energy is identified as one area for additional investment, including solar, wind, hydropower and electricity networks. Such projects could strengthen Montenegro’s role as a regional electricity exporter while attracting foreign capital. The Port of Bar and related railway infrastructure could support logistics and industrial activity through improvements in reliability and capacity.
EU integration could also increase investment in infrastructure, regulatory compliance, services and export-oriented businesses. Economic diversification would not replace tourism but would reduce the degree to which public revenues depend on continued increases in spending by tourists and households.
Fiscal adjustment increasingly concerns structure
Montenegro’s current debt position is significantly below the level recorded during the pandemic. The difference between a 63.5% debt-to-GDP ratio in 2025 and the 106.4% peak is substantial. The nominal debt stock has reached approximately €5.19 billion, while external public debt stands close to €4.85 billion and a growing proportion of government expenditure consists of established commitments.
At the same time, VAT and other consumption-linked revenues remain important to the fiscal framework. The next stage of fiscal policy therefore involves changes to the composition of revenues and expenditure. A larger contribution from productive investment and higher-value economic activity would broaden the revenue base, while infrastructure and other projects that expand future economic capacity would increase the productive component of public spending. EU accession and the associated investment cycle provide a framework for combining national resources, EU grants and international financing across infrastructure and other areas of economic development.
