5 traders jailed for rigging key interest rates have their convictions quashed

Tap title to read story

A British appellate court has quashed the fraud convictions of five former bank traders accused of manipulating benchmark interest rates following the 2008 global financial crisis. The Court of Appeal threw out the convictions of former Barclays employees Jonathan Mathew, Jay Merchant, Alex Pabon, Philippe Moryoussef, and Colin Bermingham, who were sentenced between 2016 and 2019. The ruling follows a July 2025 U.K. Supreme Court decision that overturned similar convictions for two other traders due to inaccurate judicial instructions given to jurors. Lawyers for the five appellants argued successfully that their trials suffered from identical, legally flawed jury instructions, rendering their convictions unsafe. The U.K. Serious Fraud Office stated it would not seek retrials or oppose the appeals. Libor and Euribor benchmark rates previously governed trillions of dollars in global financial products before widespread market reforms phased them out.
