UK Court of Appeal Quashes Convictions of Five Former Barclays Traders

London’s Court of Appeal has officially quashed the convictions of five former Barclays traders who were previously found guilty of manipulating global benchmark interest rates, including Libor and Euribor. The decision, delivered on Thursday, comes directly in the wake of a landmark 2025 ruling by the Supreme Court of the United Kingdom, which established that fundamental legal errors had rendered similar historical convictions unsafe.

The rulings bring a dramatic new chapter to the protracted legal aftermath of the post-2008 financial crisis investigations. For over a decade, international regulatory and prosecutorial bodies pursued a sweeping crackdown on financial benchmark rigging, resulting in massive corporate fines and numerous criminal prosecutions across multiple jurisdictions. The central allegation against the traders was that they had colluded to dishonestly manipulate interbank offered rates to benefit their own trading positions, a practice that prosecutors argued undermined the integrity of global financial markets.

However, the legal foundation of these convictions began to fracture following subsequent appeals and judicial scrutiny regarding the interpretation of English criminal law concerning dishonesty and foreign legal standards. The Supreme Court's pivotal 2025 judgment determined that the original legal directions given to juries in several benchmark-manipulation trials were flawed. Armed with this precedent, the five former Barclays employees—whose trials had taken place years prior—petitioned the Court of Appeal to review their cases under the newly clarified legal parameters.

The Court of Appeal, operating as the second-highest judicial authority in England and Wales, accepted that the Supreme Court's interpretation meant the original verdicts could not be upheld. By overturning these convictions, the appellate court has reinforced the principle that criminal culpability in complex financial crimes must strictly align with correct statutory interpretations, thereby drawing a definitive line under one of the most contentious enforcement efforts in British banking history.
