Croatia's banks were making more money than a year earlier when the first quarter closed. By the end of June that gain had gone.

Profit across the sector fell 5.5% year on year (y/y) in the first half of 2026, the Croatian National Bank (HNB) said in its commentary on banking system developments, published on August 31. Return on equity came to 15.3% and return on assets 1.6%.

Total assets of credit institutions reached €91.7bn at the end of June, up 0.6% on the end of 2025. Lending went the other way, with loans and advances down €0.4bn, or 0.6%, over the six months. What shrank was liquidity parked at the central bank and other demand deposits; credit to households and non-financial companies kept growing.

The quarter that undid the quarter

Croatia's credit institutions cleared €419.7mn between January and March, 12% more than a year earlier, on HNB figures reported by The Dubrovnik Times on June 3. Return on equity ran at 17.2% for the quarter.

Zagrebačka banka (ZABA) earned €135.8mn of that, Erste&Steiermärkische Bank €121.7mn and Privredna banka Zagreb (PBZ) €65.4mn. All but one of the country's 19 banks and its single housing savings bank were in profit. Part of the quarter's strength was a one-off, the central bank noted - a gain booked by one lender on the sale of ownership stakes, which it did not name.

Turning a 12% gain into a 5.5% half-year fall means the three months to June were markedly worse than the three before them. There was a 17.2% return on equity at the end of March, 15.3% at the end of June.

Sector assets grew 8.3% through 2025 to €91.1bn. The first six months of 2026 added 0.6%, a fraction of that pace. Loan quality did not deteriorate with it. The non-performing loan (NPL) ratio held at 2.3%, the same as at the end of 2025, and the stock of bad loans fell 0.4%. Corporate asset quality improved outright, the NPL ratio for non-financial companies dropping to 3.3% from 3.7%, while the household ratio edged down to 3.2%.

Thinner capital, thinner liquidity

The sector's total capital ratio fell to 22.1% at the end of June from 22.9% at the end of 2025. Every institution stayed well clear of the 8% regulatory minimum. Liquidity is ample and less ample than it was: the average liquidity coverage ratio stood at 196.2%, against a required 100% and against 213% six months earlier.

The HNB has been leaning against the cycle for a year. It warned in July that interest rate risk had increased, with systemic risk "moderately elevated" on strong private-sector lending and residential property prices that have outpaced incomes.

"In the event of a slowdown or reversal of the financial and economic cycle, higher levels of indebtedness increase the sensitivity of households and banks to potential shocks," the central bank said, flagging the risk of a sharper correction in house prices.

Longer-dated fixed-rate lending and holdings of long-term debt securities are the specific exposure. Banks hedge with derivatives but "cannot completely eliminate" the risk, the HNB said, and higher hedging costs have pushed some of them back toward variable-rate loans with an initial fixed period. The countercyclical capital buffer rises to 2% on January 1, 2027.

Owned from Milan and Vienna

Croatia runs one of the European Union's most concentrated and foreign-owned banking systems. ZABA, part of Italy's UniCredit, and PBZ, owned by Intesa Sanpaolo, hold roughly 46% of banking assets between them. Erste&Steiermärkische Bank, the local arm of Austria's Erste Group, has about 18%, OTP banka Hrvatska around 10% and Raiffeisenbank Austria (RBA) some 8%. Agram banka, KentBank, Istarska kreditna banka Umag, Croatia banka, Partner banka and Slatinska banka fill out the tail.

Hrvatska poštanska banka (HPB), 77% state-owned and the one substantial domestically controlled lender, ranks fifth by assets and is the exception to the earnings squeeze rather than a refutation of it. Its after-tax profit came to €36.2mn in the half, up 0.4% y/y, on net interest income of €80.3mn, up 3.6%, The Dubrovnik Times reported on July 26. Operating income rose 4.2% to €101.2mn while operating costs rose 11% to €58.8mn, and the bank made its debut on international capital markets with a €150mn bond.

Consolidation is thinning the field rather than adding to it. RBI cleared its acceptance threshold in the contest for Addiko Bank in late July, and is set to take over the Balkan lender.

The tax has not landed yet

The 50% tax on excess profit that Prime Minister Andrej Plenković's cabinet unveiled in May as part of a broad anti-inflation package is still a draft. Its public consultation closed on August 30 and the bill goes to parliament next, according to a tax alert from Deloitte.

The charge bites where a firm's 2026 profit margin runs more than 15% above its own 2023-2025 average, on medium and large companies earning more than half their revenue inside Croatia. 

Banks are in scope, subject to separate rules on how finance income and expenses enter the margin calculation - the detail that was still open when the package was announced. They earn their money at home, so the revenue test that spares exporters does nothing for them.

The timing is awkward for the finance ministry as much as for the banks. A levy designed against a 2023-2025 boom baseline arrives as the boom itself fades: measured against that average, a half-year in which profit fell 5.5% and capital ratios thinned is a smaller target than the one Zagreb was aiming at in May.

What the banks are lending into

The economy underneath is still growing faster than the bloc it joined. GDP rose 1.7% y/y in the second quarter, against 1.2% for the EU and 1% for the euro area, and Finance Minister Tomislav Ćorić expects more than 2% for the full year. 

Prices are the constraint on that consumption. Inflation reached 4.1% in August on the national measure, with energy up 17.4% y/y, though the gap to the euro area narrowed to 0.4 percentage points, the smallest since the start of 2022. The tourism season that funds the deposit base is flatter than the record one before it, arrivals and overnight stays up 1% in the first seven months.

None of this is a stressed banking system. Bad loans are low and falling, and S&P raised Croatia to 'A' in March on the strength of the same run.
