Hungary’s former central bank governor, György Matolcsy, will remain in custody after a Budapest court upheld his pre-trial detention in a major investigation linked to the National Bank of Hungary (MNB) scandal.

The court cited concerns over potential flight, interference with evidence and the risk of further criminal activity, while also pointing to Matolcsy’s extensive personal and business connections.

Matolcsy’s connections and his son’s disappearance

The Budapest-Capital Regional Court rejected appeals against the detention of Matolcsy and two other suspects, confirming the initial ruling that ordered their imprisonment until 23 November 2026. In its decision, the court highlighted the suspects’ financial resources, international mobility and alleged close family, economic and personal relationships as factors increasing the risk of them becoming unreachable by authorities.

The concerns are further heightened by the whereabouts of two alleged members of the suspected group, who are currently abroad at unknown locations. They are identified as Ádám Matolcsy, the former central bank governor’s son, and György Stofa. International arrest warrants have reportedly been issued for both individuals. The court argued that the extensive network of relationships surrounding the suspects could facilitate their escape or allow them to influence the investigation indirectly.

Evidence destruction fears deepen the investigation

The court also expressed serious concerns about potential interference with evidence in the ongoing MNB investigation. According to its statement, investigators are still analysing substantial quantities of seized electronic data and documents, identifying additional individuals and conducting witness interviews. Further questioning of existing suspects may also be necessary.

The court said concrete circumstances supported the risk of evidence being compromised. Investigators reportedly discovered documents connected to the criminal proceedings within the interests of one suspect, while circumstances suggesting the possible destruction of evidence had also emerged. The investigation has additionally uncovered documentary evidence, witness statements, audio recordings and transcripts, as well as IT data concerning the creation and alleged backdating of documents.

Why Hungary’s court rejected the bail

The court ruled that neither bail nor house arrest with electronic monitoring would sufficiently protect the investigation. According to the judges, restricting a suspect’s physical movements would not prevent indirect communication, electronic contact or attempts to influence witnesses and evidence through other individuals. A contact ban was also deemed insufficient, given that the full circle of people potentially involved in the proceedings remains unknown.

Matolcsy’s former position as central bank governor and his previously unblemished criminal record were not considered sufficient to eliminate the risk of reoffending. The court pointed to his suspected informal leadership role within an organised group, alongside long-established economic and personal relationships, as grounds for maintaining detention.

The ruling does not constitute a finding of guilt. The investigation into the MNB scandal remains ongoing, with authorities continuing to examine the alleged financial misconduct and the potential involvement of further individuals.
