FORMER DEUTSCHE BANK TRADER HAS CONVICTION OVERTURNED IN MAJOR EURIBOR MANIPULATION CASE

Christian Bittar, a former senior trader at Deutsche Bank, has won an appeal against his conviction for conspiring to manipulate benchmark interest rates, marking another major setback for Britain’s Serious Fraud Office (SFO).

On October 9, 2026, London’s Court of Appeal quashed Bittar’s 2018 conviction, which had resulted in a prison sentence of five years and four months. The decision is part of a wider series of successful appeals involving prosecutions linked to the manipulation of financial benchmarks.

A Conviction That Lasted Eight Years

Bittar had pleaded guilty in 2018 to conspiring to manipulate the Euro Interbank Offered Rate, commonly known as Euribor. The benchmark has historically helped determine interest rates on financial contracts and loans around the world.

His case was part of a major investigation into allegations that traders at international banks attempted to influence benchmark rates for financial gain. The investigation became one of Britain’s most prominent financial-crime prosecutions following the global financial crisis.

Why Did the Court Overturn the Conviction?

Bittar’s legal team argued that his guilty plea had been based on a fundamental error in the way the law was applied. His lawyer maintained that prosecutors had not been required to establish an essential element of the alleged conspiracy: that Bittar had agreed to submit false or misleading Euribor rates.

The Court of Appeal accepted the appeal and quashed the conviction. Judges had not yet published their full written reasons at the time of the Reuters report, leaving further details of the legal reasoning to be set out later.

A Wider Setback for Financial-Crime Prosecutions

Bittar’s successful appeal followed the overturning of convictions against five former Barclays traders earlier in the same week. Those decisions were linked to legal errors concerning how juries had been directed during earlier trials.

In a separate development, previous Supreme Court rulings had identified problems affecting prosecutions related to the manipulation of Libor, another benchmark interest rate. The subsequent appeals have raised serious questions about the legal foundations of several high-profile cases.

The Serious Fraud Office Responds

The Serious Fraud Office said it had argued for a different outcome but respected the Court of Appeal’s decision. The agency also reaffirmed its commitment to investigating complex fraud, bribery and corruption.

The original investigation, launched in 2012, led to prosecutions of 20 people. Several defendants were convicted, while others were acquitted. With Bittar’s conviction overturned, eight of the nine convictions in the broader rate-rigging cases had been quashed, according to Reuters.

What Happens Next?

The Court of Appeal’s decision removes Bittar’s 2018 conviction, but the ruling’s full implications depend on the court’s detailed legal reasoning. It also adds to the scrutiny facing the prosecution of complex financial crimes, where the interpretation of legal requirements can determine whether a conviction stands.

The case is a reminder that even after a defendant has pleaded guilty and served a prison sentence, an appeal can lead to a conviction being overturned if a court identifies a fundamental legal error.
