UK Crypto Debanking: Parliament Launches Inquiry as Banks Block 40% of Payments

Try opening a business bank account for a crypto firm in the UK right now. Good luck. New evidence submitted to Parliament this week shows nearly four in ten payments to crypto exchanges get blocked or delayed by UK banks — and MPs finally want to know why. On 21 July 2026, the Crypto and Digital Assets All-Party Parliamentary Group opened a formal inquiry into what the industry has been calling a banking blockade for years. It’s a big deal for anyone running, or trying to run, a crypto business from the UK.

What the APPG Inquiry Actually Covers

The inquiry is run by the Crypto and Digital Assets APPG, chaired by Lord Vaizey of Didcot alongside Labour MP Gurinder Singh Josan CBE. It’s a six-week call for evidence, open from 21 July until 31 August 2026. Banks, payment providers, crypto firms, fintechs, trade bodies, regulators, academics and consumer groups have all been invited to submit written evidence.

The scope is broad. It covers difficulty opening business accounts, hard transfer limits, outright payment blocks, and whether banks are applying restrictions proportionately or just blanket-banning anything that smells like crypto. When I looked into this, the timing struck me — it’s landing exactly as the FCA’s own crypto regime starts to bite.

Written evidence gets published on Parliament’s website once the call closes. That means every bank named in a submission will have its policy on public record, which is precisely the kind of scrutiny that tends to change corporate behaviour faster than a strongly worded letter ever could.

The Debanking Problem By Numbers

Research published in January 2026 by the UK Cryptoasset Business Council found roughly 40% of payments to crypto exchanges were blocked or delayed by UK banks. Some estimates put the value of rejected transactions at over £1 billion across the past year alone. That’s not a rounding error. That’s a functioning industry getting throttled at the payment rail.

Five names keep coming up in complaints: HSBC, Nationwide, NatWest, Santander and Starling Bank. Not every case is malicious — some reflect genuine fraud-prevention rules. But founders I’ve heard from describe accounts frozen for weeks with zero explanation, then quietly reopened once a journalist starts asking questions.

One detail from the Cryptoasset Business Council data stands out: delays cluster heavily around amounts just above the £10,000 mark, the rough threshold at which many banks’ automated fraud systems flag a transaction for manual review. Manual review, in practice, can mean a week of silence.

Why UK Banks Keep Blocking Crypto Payments

Banks will tell you it’s about fraud and money laundering exposure. Fair enough — some of that is real. Authorised push payment scams routed through crypto on-ramps have cost UK consumers hundreds of millions over the past three years, and banks carry liability for a chunk of that under the newer reimbursement rules that came into force in October 2024.

But UK investors keep asking about this because the blocking looks indiscriminate. A registered, FCA-known exchange gets treated the same as an anonymous wallet nobody’s heard of. There’s no tiering. No risk-based nuance. Just a blanket “no” that pushes legitimate businesses towards smaller, less-regulated banking partners — which, ironically, makes the system less safe, not more.

I’ve seen this pattern with three different UK exchanges now. Each one eventually found a workaround through a European e-money institution passporting into the UK. None of them found a mainstream high-street bank willing to hold their operating account long-term.

How This Fits With the Incoming FCA Regime

Context matters here. The FCA finalised its full crypto framework on 30 June 2026. The authorisation window for firms opens in September 2026, with full compliance mandatory from 25 October 2027. In other words: crypto firms are about to become formally regulated, licensed, supervised entities — and banks are still treating them like they operate in a lawless grey zone.

That contradiction is exactly what the APPG wants on record before the regime kicks in. If a firm passes FCA authorisation but still can’t get a business bank account, the whole licensing exercise starts to look pointless. Worth its weight in irony, that.

Industry bodies have been pushing for something like a “regulatory passport” — proof of FCA authorisation that banks are obliged to treat as a baseline risk signal, rather than starting every relationship from zero. Nothing like that exists yet. Whether the APPG recommends it is one of the bigger questions hanging over this inquiry. Trade bodies like CryptoUK have floated the idea in submissions to previous consultations, without much traction from the Treasury so far.

What Other Countries Are Doing Differently

The inquiry isn’t just looking inward. It explicitly wants comparisons against the US, Hong Kong, Australia and the EU. Hong Kong in particular has pushed banks toward clearer onboarding standards for licensed virtual asset firms — account access tied to licensing status, not vibes.
