Serbia kept its benchmark interest rate unchanged at 5.75% on Thursday while the European Central Bank raised rates by 25 basis points, opening a fresh gap between relatively subdued Serbian inflation and a worsening external financing environment.
The National Bank of Serbia left its benchmark rate unchanged for a ninth meeting this year, extending a pause that has lasted since September 2024. Deposit and lending facility rates remain at 4.50% and 7.00%.
Hours later, the ECB raised its deposit rate to 2.50%, the main refinancing rate to 2.65% and the marginal lending rate to 2.90%, effective from Sept. 16. The move was its second 25-basis-point increase since June.
The contrast matters for Serbia because much of the economy’s borrowing remains directly or indirectly tied to the euro.
Serbian inflation has given the NBS little domestic reason to tighten further. Annual inflation fell to 1.9% in July, below the central bank’s 3% target midpoint and comfortably inside its 3% plus or minus 1.5 percentage-point tolerance band.
But Serbia cannot isolate itself from the conditions pushing the ECB in the opposite direction.
The ECB said the Middle East conflict was continuing to generate inflation pressure and projected euro-zone inflation at 3.0% in 2026, 2.5% in 2027 and 2.1% in 2028. It also warned that the outlook remained unusually uncertain, with energy prices an important source of upside inflation risk.
For Serbian businesses, that means the prospect of cheaper euro financing has moved further away.
Many corporate loans are denominated in euros or linked to the euro, with borrowing costs influenced by euro-area market rates. The ECB increase therefore reinforces pressure on refinancing costs even though the NBS has not changed domestic monetary policy.
The effect will vary by borrower and loan structure, and some of the ECB tightening may already have been reflected in market rates before Thursday’s decision.
Still, companies planning large capital expenditures now face a less favourable external funding environment just as Serbia is trying to accelerate investment in energy, infrastructure, manufacturing and real estate.
That is particularly relevant for projects with high debt requirements.
Renewable-energy developers, industrial companies and property investors frequently model financing over long periods, making relatively small changes in borrowing costs material to project returns.
Serbia’s own corporate bond market is also beginning to expand, but bank lending remains overwhelmingly dominant.
The September decisions therefore leave Serbian companies caught between two monetary signals.
Domestic inflation argues against additional tightening and could eventually support lower rates. External inflation and euro-area policy are moving in the other direction.
The spread between the NBS benchmark rate and the ECB deposit rate will narrow to 3.25 percentage points from 3.50 points after the ECB increase takes effect.
That does not mechanically determine Serbian monetary policy, but the external rate environment matters for capital flows, exchange-rate stability and financing conditions in a highly euroised economy.
The NBS has repeatedly cited international developments among the risks influencing its decisions.
Its cautious stance has become easier to understand as energy markets have again become volatile.
Earlier this year, the central bank said higher world oil prices were already feeding into Serbian petroleum prices, although government intervention through lower fuel excise duties and releases from reserves softened the impact.
The question for autumn is whether that pressure returns strongly enough to disturb Serbia’s currently benign inflation numbers.
A renewed rise in fuel, electricity or imported production costs could squeeze corporate margins before appearing fully in consumer inflation.
The next Serbian inflation readings will therefore carry more weight than the headline 1.9% July figure suggests.
For the NBS, there is little incentive to rush.
Inflation is low enough to avoid tightening, while the renewed external shock makes an early rate cut harder to justify.
For borrowers, that probably means 5.75% remains the domestic anchor for longer, while euro funding has just become more expensive.
Serbia entered September looking increasingly close to the point where falling inflation might reopen the debate over monetary easing. The ECB’s move has not closed that door, but it has made the corridor leading to it considerably narrower.
