English Premier League football club Chelsea’s new front-of-shirt sponsorship deal with stablecoin issuer Circle, featuring its USDC brand on player jerseys for the 2026-27 season, has left Hong Kong fans and retailers concerned about whether wearing or selling the top counts as illegal promotion under local digital currency laws. The deal was signed in late August, just three months after the UK’s Financial Conduct Authority (FCA) warned Premier League clubs about crypto sponsorships.
