UK legislators have urged financial institutions to broaden cryptocurrency access ahead of a new Financial Conduct Authority regulatory framework set to take effect in October 2027, according to a letter sent to bank chief executives.
The letter, sent by co-chairs of the All-Party Parliamentary Group on Cryptocurrency and Digital Assets, frames banking access as a structural constraint on the sector's growth. The group told banks that restricted crypto rails could prove "one of the single biggest barriers to growth" as the FCA's regime comes into force, pressuring lenders to expand services before the rules land.
The FCA regime, due October 25, 2027, will introduce new stablecoin and cryptoasset service provider regulations. UK banks have narrowed crypto payment channels in recent years following fraud concerns and money laundering scrutiny, leaving payment processors and crypto firms with reduced on-ramp and off-ramp capacity. Lawmakers view this bottleneck as an impediment the sector cannot absorb once new compliance obligations activate.
Research from January 2026 found that crypto payments faced significant friction in UK banking channels, with 40 percent of transactions blocked or delayed by payment processors. The constraint hits retail users, institutional traders moving between fiat and crypto, and businesses accepting digital currency payments. Major UK banks have cited operational risk and regulatory uncertainty as reasons for declining or limiting crypto-linked accounts, forcing legitimate crypto firms into relationships with smaller or overseas lenders.
The letter arrives as the FCA has begun publishing detailed guidance on stablecoin issuance and transfers of crypto assets. Banks face a choice: build compliance infrastructure and crypto desks ahead of the October 2027 deadline, or cede the market to non-bank payment networks and private stablecoin operators. Parliament views restricted access as a policy failure rather than a prudent risk stance.
The timing puts pressure on lenders before the FCA's regime hardens into enforcement. If banks do not expand capacity before October 2027, the new framework could lock existing market structure in place, forcing crypto users and businesses onto decentralized or offshore rails. The letter names the problem but does not outline penalties or incentives for compliance.
Banks face a window of roughly 16 months to decide whether expanded crypto banking represents acceptable risk or a trap set by an immature market. The FCA regime will define what compliance looks like; the letter is Parliament's direction that failure to participate will be read as a market failure, not prudence.
