UK Banks Hit With 10,000 Complaints Over Blocked Crypto Transfers in 90 Days: Report

Introduction

A recent Stand With Crypto report reveals that UK bank customers lodged 10,092 complaints about blocked or restricted fiat transfers to cryptocurrency exchanges over a 90‑day period (May‑August 2026). The complaints spanned all 650 parliamentary constituencies, highlighting a nationwide friction point between traditional banking and the growing crypto ecosystem. The data has reignited debate over how banks should handle crypto‑related payments, especially as the FCA’s new crypto regulatory framework is set to take effect next year.

Who is complaining and where?

• Lloyds Banking Group topped the list with 2,297 complaints (≈22% of the total), despite having no publicly‑available policy on crypto transfers.
• Barclays followed with 1,569 complaints, and NatWest Group (including Royal Bank of Scotland) recorded 1,278.
• HSBC UK also exceeded 1,000 complaints, though the exact figure was not disclosed.
• Smaller players such as Virgin Money and the Co‑operative Bank saw the fewest complaints, with 103 and 76 respectively.

The report notes that complaints were filed by 9,803 individual customers, many of whom submitted multiple grievances. While the figures are not weighted by each bank’s market share, they illustrate a clear pattern: customers are encountering barriers regardless of the institution they use.

How banks are responding – limits versus bans

Six banks publish explicit limits on crypto‑related transfers:

• Barclays: £2,500 per transaction, £10,000 per 30‑day period.
• NatWest: £1,000 per day, £5,000 per 30‑day period.
• Santander UK: £1,000 per transaction, £3,000 per 30‑day period.

Seven banks block crypto transfers outright: Starling, TSB, Chase UK, Metro Bank, Virgin Money, the Co‑operative Bank, and (as reported) others that have not disclosed any policy.

The complaint distribution reflects these approaches:

• Banks with published limits received 6,198 complaints.
• Banks with no published policy (Lloyds and Revolut) accounted for 2,842 complaints.
• Banks that ban transfers completely saw 989 complaints, possibly because customers are aware of the restriction and refrain from attempting transfers.

Bank spokespeople typically cite fraud prevention as the rationale. Barclays emphasized protecting customers from scams, while NatWest referenced a “growing risk from fraudsters” and noted that it blocked or limited crypto‑related Faster Payments from March 2023.

Regulatory backdrop and industry reaction

The FCA and Treasury are preparing to enforce a new crypto regime in 2027. The Stand With Crypto report references a 2025 FCA‑YouGov survey where 13% of UK crypto users reported difficulties withdrawing crypto to their bank accounts, the most common negative experience. A separate survey by the UK Cryptoasset Business Council estimated that banks block or delay roughly 40% of transfers to the ten largest UK exchanges, with one exchange seeing close to £1 billion in declined transactions over a year.

Parliamentary scrutiny is also intensifying. The Crypto and Digital Assets All‑Party Parliamentary Group launched an inquiry in July 2026 into banks’ treatment of crypto firms and the limits they impose. In August, co‑chairs Labour MP Gurinder Singh Josan and Lord Vaizey of Didcot wrote to the CEOs of every major UK bank requesting details on their crypto‑related policies.

What advocates are asking for

Stand With Crypto’s recommendations focus on moving away from blanket bans toward risk‑based, case‑by‑case assessments:

1. Publish clear, plain‑language policies that explain when and why a transfer may be blocked.
2. Provide a transparent appeals process for customers who believe a legitimate transaction was wrongly restricted.
3. Encourage the FCA and HM Treasury to publicly state that sector‑wide caps are unlikely to be justified under anti‑fraud or financial‑crime rules once the new regime is active.

The group argues that overly broad restrictions could become “one of the single biggest barriers to growth” for UK crypto businesses, especially as firms seek FCA authorization and assurance that they will not face arbitrary banking hurdles.

Practical takeaways for customers and banks

• Customers should check whether their bank publishes a crypto‑transfer policy before initiating a payment. If limits exist, plan transactions to stay within daily or monthly caps, or consider using a bank that offers higher thresholds.
• Banks can mitigate complaints by communicating policies proactively, offering dedicated support channels for crypto‑related queries, and adopting risk‑scoring models that differentiate legitimate user activity from high‑risk behavior.
• Regulators have an opportunity to set industry‑wide standards that balance fraud prevention with the need for accessible financial services for crypto participants.

Closing thoughts

The surge of over 10,000 complaints in just three months underscores a friction point that could hinder the UK’s ambition to become a leading crypto hub. As the FCA’s new framework approaches, banks, policymakers, and advocacy groups must collaborate to replace blanket bans with nuanced, transparent controls. Doing so will not only reduce consumer frustration but also foster a more resilient, innovation‑friendly financial ecosystem.
