Commerzbank Cum-Ex charges reach back to 2008 trades and land on four individuals

Frankfurt's General Prosecutor's Office has charged four former Commerzbank employees over Cum-Ex dividend-stripping trades executed in 2008, alleging more than 20 million euros in tax losses to the state of Hesse ^[1][2]. The relevant fact for operators is not the sum but the reach: positions taken in 2008, four years before the German legislature closed the loophole in 2012, are still generating individual criminal exposure ^[2][6][17].

The mechanics are well documented. Shares were bought and sold rapidly around a dividend date so that more than one party appeared to own the same stock, and each then claimed a refund on withholding tax that had been paid only once ^[5]. The activity clustered between roughly 2006 and 2011, with Germany absorbing the largest share of the damage and comparable schemes surfacing in Denmark, Belgium and other European markets ^[6][14].

The defendant list is the part worth studying if you run a cross-border team. Prosecutors name two British nationals aged 66 and 59, a 61-year-old German and a 60-year-old American ^[3]. Three were based in London and one in Frankfurt, meaning three quarters of the charged group sat outside German territory ^[4][18]. Prosecutors allege they worked across borders to exploit what were then gaps in German tax law, and according to the Cryptobriefing account of the filing, the precise role of each defendant will be tested at trial ^[15].

Commerzbank itself is not in the dock. The bank has said it is not a party to these proceedings and that the charges are directed at the four individuals rather than the institution ^[9], and it has maintained that it cooperates fully with authorities ^[8]. That is a narrower comfort than it sounds. German authorities searched the bank's offices in 2017 and 2019 as part of broader Cum-Ex investigations ^[7], and the pattern since has been to pursue people.

Bonn district court delivered Germany's first Cum-Ex criminal conviction in 2020 ^[10]. Hanno Berger, the tax lawyer described in the same report as a central architect of the structures, was convicted and sentenced in 2022 after years spent avoiding prosecution from Switzerland ^[11]. Recent convictions have produced prison sentences rather than fines ^[13]. Set against estimates that put the cumulative cost to European treasuries above 55 billion euros, contested as those figures are, the 20 million euros at issue here is roughly four hundredths of one percent of the total ^[12][16].

Two things to watch. First, whether the case reaches trial and how a German court apportions individual responsibility among four people spread across two financial centres and three nationalities ^[15][3][4]; the London-based defendants may not move at the same pace as the Frankfurt one ^[4]. Second, whether further charges emerge from the same 2006 to 2011 window, which is where the volume was ^[6]. For compliance functions, the practical read is that an institution's cooperation posture does not settle a former employee's personal position on trades this old ^[9][8].
