A UK crypto advocacy campaign says consumers used its online tool to submit 10,092 complaints about blocked or restricted bank transfers to cryptocurrency platforms during a 90-day period between May and August 2026. Stand With Crypto UK said the submissions came from 9,803 people across all 650 parliamentary constituencies. The figures point to widespread frustration, but they measure use of a campaign tool rather than every rejected payment in the banking system.

Three banking groups drew half of the submissions

Lloyds Banking Group, including Halifax and Bank of Scotland, received 2,297 complaints in the campaign's dataset. Barclays received 1,569 and NatWest Group 1,278. Together, the three groups accounted for 5,144 submissions, or about 51% of the total. Those counts do not show how often each institution allows or blocks a crypto transfer because the campaign did not publish the number of attempted payments or adjust for the size of each bank's customer base.

The methodology limits comparisons

The submissions were made voluntarily by people who chose to use Stand With Crypto's complaint tool. They were not drawn from a representative sample, independently audited bank records or Financial Ombudsman Service case data. One person could submit complaints about more than one incident, which explains why submissions exceeded the number of participants. The results therefore document reported friction and the reach of the campaign, not a marketwide failure rate or proof that one bank rejects a larger share of transfers than another.

Published policies vary across lenders

CoinDesk reported that the campaign's review of bank websites found a mix of transaction limits, monthly caps and outright prohibitions. Barclays was listed with a limit of 2,500 pounds per transaction and 10,000 pounds over 30 days. NatWest was listed at 1,000 pounds per day and 5,000 pounds over 30 days, while Santander's stated limits were 1,000 pounds per transaction and 3,000 pounds per month. Other institutions were identified as prohibiting crypto-related payments. Banks may also review individual transfers for fraud, scams, money laundering and recipient risk, so a published cap does not explain every decision.

Access and consumer protection are separate questions

The dispute comes as the UK prepares to bring more cryptoasset activity inside the financial regulatory perimeter from 2027. HM Treasury has said the regime is intended to support responsible innovation, open competition and stronger consumer protection. Banking access is a related but distinct issue: regulating an exchange does not require every bank to process every payment to it. The policy question is whether restrictions are proportionate, clearly disclosed and paired with a practical way to challenge mistakes.

Complaint counts do not invalidate fraud controls

Banks remain responsible for detecting scams, unauthorized payments and money laundering, and crypto transfers can present heightened risks when customers are pressured to move funds quickly. The campaign data does not show which blocked payments involved suspected fraud, which were later approved or whether customers recovered money after a review. Any comparison therefore needs both access data and evidence about the losses that controls prevented.

What would make the picture clearer

Comparable data from banks would help separate routine fraud controls from blanket restrictions. Useful disclosures would include attempted crypto-transfer volumes, approval and rejection rates, reasons for declines, appeal outcomes and the treatment of payments to UK-registered firms. Until such figures are available, the 10,092 complaints are best read as evidence of customer concern and inconsistent expectations, not as a ranking of bank performance or a measure of total UK demand for crypto.
