The co-chairs of the UK Parliament's Crypto and Digital Assets All-Party Parliamentary Group (APPG) have written to the CEOs of major UK banks, demanding an explanation for their treatment of cryptocurrency and digital asset companies. The letter highlights that crypto firms frequently encounter difficulties opening bank accounts in the UK, and several banks restrict crypto-related payments. This, they suggest, could become the biggest impediment to the growth of the UK's crypto business and potentially undermine the success of the UK's upcoming crypto regime. The MPs posed six questions to each bank, covering their policies, whether they serve crypto companies, restrictions on crypto-related transactions, and how the future regime will impact their practices.
