The European Central Bank’s latest interest-rate increase could moderate the decline in borrowing costs in Montenegro rather than produce a sharp increase, as the country’s banks rely heavily on domestic deposits and relatively few loans have variable rates, according to the Central Bank of Montenegro.
ECB increase has limited immediate transmission
The ECB raised its interest rates by 0.25 percentage points in September, tightening financing conditions across the euro area. Montenegro uses the euro but remains outside the Eurosystem, so ECB monetary policy influences domestic borrowing costs without Montenegro participating directly in the decisions.
The immediate effect on existing borrowers is expected to be limited because only 6.12% of outstanding bank loans in Montenegro carry variable interest rates. This means relatively few borrowers have repayments that automatically adjust when European benchmark rates change.
Domestic deposits provide banks with stable funding
Montenegrin banks are primarily financed through domestic deposits rather than wholesale funding from European markets. Household and corporate deposits stood at €6.49 billion at the end of August, accounting for 89.92% of bank liabilities excluding capital.
This funding structure provides banks with greater insulation from changes in international financing costs. The banking sector also remains highly liquid, with deposits above €6 billion, low non-performing loans and strong capital levels.
Lending rates have fallen over two years
Borrowing costs in Montenegro have declined over the past two years. The average effective interest rate on newly approved loans fell to 6.35% in August 2026, compared with 6.73% two years earlier. For households, the average rate declined from 7.76% to 6.90%, while the rate for corporate loans decreased from 5.93% to 5.56%.
The decline was more pronounced for new housing loans, where rates fell to approximately 5.02% from 6.0%. CBCG expects the ECB increase to make additional reductions more gradual, particularly if financing costs in European markets remain elevated.
Mortgage and corporate lending could face slower rate declines
Lower mortgage rates and strong bank liquidity have supported housing demand in Montenegro. A slowdown in the decline of borrowing costs could reduce some of that support, although current rates remain below their levels two years ago. Corporate borrowers could face a similar adjustment. Montenegrin banks have substantial liquidity and strong deposit bases, reducing the need for aggressive loan repricing. At the same time, lenders will take into account the opportunity cost of funding as euro-area interest rates increase.
The result is expected to be a more gradual adjustment than in banking systems that depend more heavily on external wholesale financing.
Fixed-rate borrowers face limited immediate impact
The relatively small proportion of variable-rate lending also limits the immediate effect on households. Borrowers with fixed-rate loans will not see their repayments change solely because of an ECB rate increase. For new borrowers, however, financing could become less favourable if banks stop reducing rates or begin incorporating higher European benchmark costs into new lending.
The main effect is therefore expected to concern the pace of new lending conditions rather than immediate stress across the existing loan portfolio.
Bank competition remains a factor in lending costs
Strong liquidity, high deposit levels, low non-performing loans and solid capital positions continue to support competition among Montenegrin banks for borrowers. That competition has contributed to the decline in lending rates. The ECB’s latest move could now slow that downward trend, leaving Montenegro with a more gradual improvement in borrowing conditions, particularly for mortgages and corporate investment loans, after two years of declining rates.
