György Matolcsy, the former governor of Hungary's central bank and a long-time ally of Prime Minister Viktor Orbán, was detained on Wednesday morning and taken to the Central Chief Prosecution Office for Investigations. The move marks a significant escalation in a probe that has been circling the National Bank of Hungary (MNB) for months.
Matolcsy's lawyer, Pál Bátki, told the Hungarian daily Telex that his client is suspected of "the felony of financial fraud causing significant financial loss and the misdemeanour of using a forged private document." Bátki added that questioning had not yet begun but was expected to take place later that morning.
The prosecution office confirmed in a statement that it was conducting coordinated operations at several locations as part of an investigation into suspected breach of trust causing particularly significant financial loss. Further details are expected once initial investigative steps are completed, likely by early evening.
Being detained for questioning does not mean Matolcsy has been remanded in pre-trial custody. Whether he will be allowed to leave after questioning remains unclear. If formally named as a suspect, a court could decide on pre-trial detention.
Foundations under scrutiny
The current leadership of the MNB and Hungary's State Audit Office have both filed criminal complaints concerning the central bank's foundations. At the heart of the matter is Optima Investment, the asset manager of the Pallas Athéné foundations established by the MNB under Matolcsy in 2014 and merged in 2019. Optima managed nearly 500 billion forints (more than €1 billion) in public funds.
The State Audit Office has identified an opaque network of companies and investments, serious management failings, and suspected criminal offences. The merged foundation, PADME, and Optima subsequently faced severe financial difficulties. Hungarian media have also reported links between the investment network and associates of Matolcsy's son, Ádám.
Matolcsy has previously denied allegations concerning the management of the central bank foundations' funds. In September, he was questioned as a suspect in a separate case over alleged abuse of office involving pressure on Erste Bank Hungary, part of Austria's Erste Group. He denied those allegations and was released after questioning.
Investigators have also been examining suspected breach of trust involving the foundations and the renovation of the MNB's headquarters, alongside a separate money laundering investigation. In May 2026, authorities said they had seized cash and securities worth 91.8 billion forints.
On 26 May 2026, Hungary's parliament adopted a resolution to establish an inquiry committee into alleged abuses at the central bank. The case has drawn attention across Europe, as it touches on the governance of public funds in one of the EU's member states. While the investigation is domestic, it resonates with broader concerns about the rule of law and financial oversight in the region.
Matolcsy, who led the MNB for 12 years until 2025, remains a polarising figure in Hungarian economic policy. His tenure saw unconventional measures and close alignment with Orbán's government, making the current legal proceedings a closely watched development in Budapest and beyond.
