The National Bank of Hungary and its wholly owned subsidiary, MNB-Ingatlan Kft., filed two complaints with the Budapest Metropolitan Police on Nov. 4, 2026, concerning the bank guarantee linked to the renovation of the central bank’s headquarters and the operation of its real estate assets. The filings detail measures taken by the new management in operating those assets and calling on the guarantee. They were made in response to media reports concerning business interests linked to the previous central bank leadership and information the bank described as false.
