The UK banking industry has been tightening regulations on crypto transactions, with major banks such as Nationwide and HSBC imposing restrictions on buying cryptocurrencies. Nationwide no longer allows customers to buy crypto with credit cards, and debit card purchases are limited to £5,000 per day. HSBC has banned credit card purchases of digital assets and only allows debit card transactions through certain UK-regulated platforms. Other banks like Lloyds, NatWest, Barclays, and Santander have also imposed various restrictions. However, challenger banks such as Monzo and Revolut remain more crypto-friendly, with Revolut allowing users to buy, sell, and store digital assets through its app.
