Several major global banks, including JPMorgan, UBS, Citigroup, Barclays, MUFG, and NatWest, have successfully blocked a £2.7 billion ($3.6 billion) opt-out collective action in the UK’s Supreme Court. The proposed lawsuit, led by Phillip Evans, aimed to represent thousands of investors, pension funds, and institutions impacted by alleged foreign exchange (forex) market manipulation.
An article in Yahoo Finance reports that the case stemmed from earlier European Commission findings that fined multiple banks over €1 billion for operating cartels in forex trading. Evans’ action, filed under the UK’s collective proceedings regime, sought to recover damages on behalf of a wide investor class. However, the Supreme Court upheld a lower tribunal’s decision that the claim could not proceed on an opt-out basis, requiring instead that individual claimants opt in.
The judgment emphasized the insufficient participation rate among potential class members and found that an opt-out mechanism was not appropriate given the specifics of the case. Justice Vivien Rose, delivering the court’s opinion, noted that while individual claims might have merit, the representative structure lacked the cohesion and commitment necessary to justify a mass claim. As a result, the banks have succeeded in halting what would have been one of the largest collective actions in the UK to date.
