The Bank of England abandoned its proposal to cap individual and corporate stablecoin holdings, scrapping limits that would have restricted consumers to £20,000 ($27,000) and businesses to £10 million each, according to a policy statement released Monday. The central bank will instead impose a temporary aggregate ceiling of £40 billion ($50.6 billion) on the total circulation of any single systemic stablecoin.

Market Context

The reversal marks a significant shift from the BoE's original stance, which drew sharp criticism from crypto industry participants and members of Parliament alike. Stablecoins—digital tokens pegged to fiat currencies like sterling or the dollar—are increasingly used for payments, DeFi transactions and cross-border settlements. The U.K. has been working toward establishing a comprehensive regulatory framework for digital assets, with full implementation expected in 2027.

Analysis

The BoE said it revised its approach after receiving substantial feedback during a consultation period that ended earlier this month. Industry advocates had argued the original caps would undermine business viability and damage the United Kingdom's competitiveness as a crypto hub. A cross-party House of Lords committee specifically urged regulators to reconsider, warning the limits could have a significant impact on stablecoin issuer operations.

Under the revised framework, everyday users and large businesses will no longer face restrictions on the amount, frequency or type of stablecoin transactions they can execute. The central bank lowered the required share of non-interest-bearing central bank deposits backing stablecoins to 30%, allowing issuers to invest up to 70% of reserves in short-term U.K. government debt with maturities under six months.

While issuers may now harvest yield from these T-bills, the BoE is maintaining its ban on direct interest or dividend payments to coin holders. However, activity-based rewards—such as cash-back tokens or loyalty points tied directly to payment transactions through Web3 applications—remain explicitly permitted.

The aggregate cap serves as a macro-level guardrail designed to protect the broader U.K. credit system from sudden capital flight while still permitting innovation and market growth. The BoE indicated it intends to phase out this ceiling once the stablecoin market matures and stabilizes under comprehensive crypto regulations expected in 2027.

Key Numbers

- £40 billion ($50.6 billion): New aggregate cap on total circulation for any single systemic stablecoin

- £20,000: Individual holding limit that was abandoned

- £10 million: Corporate holding limit that was scrapped

- 30%: Required share of reserves held in non-interest-bearing central bank deposits (down from previous requirements)

- 70%: Maximum allocation issuers may place in short-term U.K. government debt (T-bills under six months maturity)

What to Watch

The BoE will accept final feedback through a window closing in September before the framework takes effect. Market participants should monitor for any additional adjustments to reserve composition rules or modifications to the activity-based rewards provisions. The 2027 full implementation date remains the target for comprehensive U.K. crypto regulation, which will determine whether the aggregate issuance guardrail is lifted as the market matures.
