Matolcsy is seen as a close ally of Viktor Orbán, who ruled the country until this spring. Orbán's successor as prime minister, Péter Magyar, has promised to hold former rulers accountable for corruption and mismanagement.
In Matolcsy's case, the allegations relate to embezzlement and fraud, according to the lawyer.
Matolcsy was governor of the central bank from 2013 to 2025 and previously served as a minister in Orbán's governments.
