UK consumers trying to move money to cryptocurrency exchanges are running into a wall of bank restrictions, according to new figures from advocacy group Stand With Crypto. Between May and August 2026, 9,803 people registered a total of 10,092 complaints through an online portal, describing transfers to exchanges that were blocked or capped by their banks.

Three lenders accounted for roughly half of the complaints. Lloyds Banking Group, which includes Halifax and Bank of Scotland under the same corporate umbrella, drew 2,297 complaints. Barclays followed with 1,569, and NatWest with 1,278. Together the three banks represent about 51 percent of all complaints logged on the portal.

The complaints point to a patchwork of limits rather than outright bans at the largest banks. Barclays caps payments to crypto exchanges at 2,500 British pounds per transaction and 10,000 British pounds per month. NatWest is more restrictive still, limiting customers to 1,000 British pounds per day and 5,000 British pounds within any 30-day period.

Beyond the three largest names, Stand With Crypto says six further banks block payments to crypto exchanges entirely, though it has not identified them. The group also notes that 28 percent of all complaints were directed at banks that have never published their restrictions publicly, leaving customers to discover the limits only when a transfer fails.

Fraud prevention versus access

Banks have defended the restrictions as a response to fraud risk, arguing the limits protect customers from financial losses linked to scams involving crypto purchases. Stand With Crypto does not dispute that fraud concerns are real, but argues that blanket limits applied regardless of a customer's history or the destination of funds are disproportionate. The group is calling on banks to move toward individual risk assessments rather than fixed caps applied to an entire category of payment.

The dispute carries particular weight because the restrictions are not confined to obscure or offshore platforms. According to the complaints data, they also affect exchanges registered with the UK Financial Conduct Authority, meaning customers using platforms that have already cleared the country's regulatory bar are still finding their payments blocked or throttled by their own bank.

For now, the figures represent self-reported complaints rather than a regulatory finding, but the scale and concentration among a handful of major banking groups is likely to sharpen scrutiny of how UK lenders police the boundary between fraud prevention and access to a regulated market.
