OTP Bank remained by far Hungary’s largest banking group at the end of 2025, with consolidated total assets of HUF 45.505 trillion, equivalent to 53% of the combined balance sheet of Hungarian banking groups, according to National Bank of Hungary data.
The nine banking groups covered by the MNB data had combined assets of roughly HUF 85.9 trillion at year-end. OTP alone was therefore larger than the next eight groups combined excluding MBH and K&H.
MBH holds 15.3% market share
Hungarian-owned MBH Bank ranked second with consolidated assets of HUF 13.123 trillion, representing 15.3% of the banking-group total. Belgian-owned K&H, part of KBC Group, ranked third with HUF 6.217 trillion, or 7.2%.
The next four positions were occupied by foreign-owned groups. Erste Bank had assets of HUF 5.254 trillion, followed by UniCredit Bank at HUF 5.035 trillion, Raiffeisen Bank at HUF 4.696 trillion and CIB Bank at HUF 3.870 trillion.
Hungarian-owned Gránit Bank ranked eighth with HUF 1.822 trillion, while MagNet Bank had HUF 391 billion in consolidated assets. Based on those figures, Erste accounted for around 6.1% of banking-group assets, UniCredit 5.9%, Raiffeisen 5.5%, CIB 4.5%, Gránit 2.1% and MagNet about 0.5%.
OTP and MBH together control more than two-thirds of banking-group assets
OTP and MBH together accounted for approximately 68.2% of the consolidated assets of the nine banking groups, while adding K&H takes the combined share of the three largest groups to about 75.5%.
The concentration is also visible in the MNB’s broader sector statistics. At the end of 2025, the five largest Hungarian credit institutions accounted for 74.3% of total sector assets, while the ten largest controlled around 93%.
Domestic ownership approaches 69%
The MNB’s broader supervisory data show that nine domestically controlled credit institutions accounted for close to 69% of sector assets at the end of 2025, with their share continuing to rise during the fourth quarter.
That structure is driven mainly by OTP and MBH, while Gránit and MagNet add smaller domestically controlled platforms. At the end of 2025, Hungary had nine banking groups, nine individual credit institutions and 10 branches of foreign institutions.
Total banking-sector assets exceed HUF 101 trillion
The wider Hungarian credit institution sector ended 2025 with HUF 101.174 trillion in total assets, up 3.2% year-on-year and 1.3% from the previous quarter. Loans represented 58% of total assets, with the loan stock reaching HUF 58.677 trillion, up 7.6% from a year earlier.
Debt securities accounted for close to one-quarter of sector assets at HUF 24.399 trillion, while cash, central-bank balances and other sight deposits totaled HUF 11.782 trillion.
The sector entered 2026 from a strong capital and liquidity position. The MNB said return on equity reached 18.9% at the end of 2025, while the preliminary capital adequacy ratio stood at 20.1% and free capital above regulatory requirements amounted to HUF 2.025 trillion.
