MKB Bank, initially Magyar Külkereskedelmi Bank, was a Hungarian state-owned bank founded in 1950. It was privatized in the mid-1990s, then renationalized in the 2010s. It eventually merged in the early 2020s with Budapest Bank and Takarékbank to form Magyar Bank Holding, branded MBH Bank, thus creating the second-largest commercial bank in Hungary behind OTP Bank. The complex three-way merger was announced in 2020 and completed in 2023.
