Germany's largest Cum-Ex tax fraud trial begins in Siegburg with three bankers accused
A major Cum-Ex tax evasion trial has opened in Siegburg, marking another chapter in Germany's crackdown on the controversial trading scheme. Three former bankers face charges of causing tax losses totalling hundreds of millions of euros. The case is being heard in a newly built €50 million courthouse designed for complex financial proceedings. The trial centres on two ex-employees of M.M. Warburg, a Hamburg-based private bank, along with a third individual accused of aiding the scheme. Prosecutors claim the defendants carried out Cum-Ex trades, which exploited loopholes to reclaim taxes that were never paid. The alleged fraud resulted in losses of around €280 million for the German treasury.
The proceedings are set to run for at least 53 days, with a conclusion expected by mid-December. This case is part of a wider investigation into Cum-Ex practices, with authorities preparing further trials. Up to seven more indictments could follow later this year, though only two additional Cum-Ex cases are confirmed to begin in Bonn before 2024 ends. The trial is taking place in the Bonn Regional Court's specialised Siegburg facility, completed just last year. The courthouse was purpose-built to handle large-scale financial crime cases, reflecting the scale and complexity of such investigations.
If convicted, the defendants could face significant penalties for their roles in the alleged tax fraud. The outcome may also influence upcoming trials, as prosecutors continue targeting similar schemes. Authorities have indicated no further Cum-Ex cases are scheduled in Germany beyond those planned for the next two years.
