Former Cum-Ex Investigator Brorhilker: Deficits in the Fight Against Tax Crimes - Germany's Cum-Ex scandal exposes systemic failures in fighting financial crime

The Cum-Ex scandal remains one of Germany's largest tax fraud cases in history, with financial losses estimated at around €40 billion. Recent legal rulings and ongoing investigations continue to shape its aftermath. Now, a former investigator has spoken out about systemic failures in tackling white-collar crime.

In 2021, the Federal Court of Justice (BGH) ruled that Cum-Ex transactions were criminal offences. This decision set a legal precedent, leading to multiple convictions of individuals involved in the scheme. More recently, the same court ordered the Bonn Regional Court to re-examine whether Hamburg banker Christian Olearius should repay €40 million linked to alleged Cum-Ex profits.

Anne Brorhilker, a former senior public prosecutor who investigated Cum-Ex cases, has highlighted deep flaws in Germany's approach to financial crime. She criticised the lack of a centralised authority, describing the current system as a fragmented network of state agencies with weak coordination. Brorhilker also accused political leaders of undermining her investigations while she worked on the case. Beyond Cum-Ex, she estimates that tax evasion costs Germany roughly €100 billion annually—a figure far exceeding official calculations. Today, Brorhilker serves on the board of Finanzwende, a citizens' initiative pushing for financial reform.

The Cum-Ex scandal has exposed gaps in Germany's legal and financial oversight. Courts continue to pursue cases tied to the scheme, while critics like Brorhilker argue that broader systemic changes are needed. The long-term impact of these failures remains a key concern for policymakers and investigators.
