György Matolcsy, the former governor of Hungary’s central bank, has been detained as prosecutors investigate alleged fraud tied to foundations set up during his tenure. The investigation, led by the Central Investigation Unit of the Prosecutor’s Office with police, has been under way since early 2025. Prosecutors say the case involves the so-called NBH file and the handling of funds connected to foundations created by the bank under its previous leadership. Prosecutors also linked the probe to concerns raised by Hungary’s Court of Auditors about investments made by the foundation and its asset-management company. In April, Matolcsy said the central bank had no legal mandate allowing it to intervene in the foundations’ operations, adding that they acted independently. Telex reported that he was detained on Wednesday morning along with other people involved in the investigation. Prosecutors stated that the inquiry concerns the offence of fraudulent management of funds, allegedly causing a particularly significant financial damage. They did not provide further details, saying the investigation includes actions in multiple locations. The latest reported operation came in May, when Hungarian prosecutors and police seized funds and securities worth about 92 billion forints, equivalent to roughly 300 million US dollars, in a separate investigation into money laundering targeting central bank foundations established years earlier. Matolcsy remains detained, with prosecutors preparing further investigative steps including questioning, as the investigation continues.
