The Bank of England has released new guidance for stablecoin regulation, marking a significant shift from its previous restrictive approach. The central bank is removing individual and corporate holding limits for pound-backed stablecoins, replacing the original caps of 10,000-20,000 British pounds for individuals and 10 million pounds for businesses. Under the new framework, the BoE is planning to temporarily limit each U.K. stablecoin to 40 billion pounds, or about $53 billion USD. The central bank has also increased the permissible share of backing assets that can be held in short-term government debt to 70% from 60%, with the remainder required in non-interest-bearing central bank deposits. The guidance will be open for public comment until September 22, with finalization expected by the end of 2026.
Stablecoins have achieved remarkable scale by 2026, with total value in circulation surpassing $300 billion and annual transfer volume reaching into the tens of trillions. According to reports from The Block, this transfer volume rivals or passes the throughput of major payment networks, demonstrating the infrastructure role stablecoins now play in global finance. The market is dominated by two tokens, Tether's USDT and Circle's USDC, which account for the large majority of market share. Close to 99% of all stablecoin value is tied to the dollar, with euro-denominated tokens still measured in the hundreds of millions rather than the tens of billions. The Bank of England's guidance comes as U.S. dollar-backed stablecoins dominate the market, with the central bank acknowledging that most developed countries are in a position where they will need to establish a stablecoin infrastructure framework.
The fiat-backed model dominates the market, where issuers hold one dollar of real assets in reserve for every token in circulation, typically cash and short-term US Treasury bills. As reported by The Block, USDT and USDC both operate this way, with the peg maintained through redemption at par for approved partners. This model is simple, scalable, and easiest to verify, which is why it dominates the market. The mint-and-burn cycle, combined with redemption at par for approved partners, creates the anchor that keeps market price near one dollar. In 2026, reserve standards tightened sharply, with major dollar stablecoins expected to hold 100% backing in cash and liquid government debt, publish regular attestations, and submit to independent audits. The Bank of England's guidance includes consumer protections and transparency requirements for issuers regarding the reserve assets that back the stablecoins, though the U.K. is projecting a heavier hand than the U.S. and EU, saying stablecoins pose credit risk for consumers and a "run" risk for banks.
USDT leads the market with circulation around $185-190 billion and a market share near 60%, running across many blockchains and dominating trading pairs worldwide. USDC holds the second position at roughly $77-79 billion, positioning itself as the compliance-first option with full attestation, European licensing, and favored by US institutions. USDS, the Sky protocol's token, leads the decentralized crypto-collateralized segment, while PayPal's PYUSD reaches mainstream users through PayPal and Venmo. Tether's USAT arrived as a US compliance-focused sibling to USDT, issued through a federally chartered digital-asset bank, and Ripple's RLUSD competes in the institutional settlement niche. The Bank of England's new guidance represents a significant course correction, with Joey Garcia, chief policy and regulatory affairs officer at Xapo Bank, noting it delivers the same policy outcome while being "cheaper and easier to implement, and allowing unrestricted use by households and businesses."
Stablecoins serve multiple critical functions across the crypto ecosystem, as reported by The Block. They function as base trading pairs on exchanges, the unit most crypto prices are quoted against, and serve as settlement layer for decentralized finance where lending, borrowing, and trading protocols need stable units. Stablecoins have become payment and remittance rail for cross-border transfers, allowing dollars to move across borders in seconds for a fraction of a cent, particularly valuable in countries with weak currencies or unreliable banking systems. They serve as on-ramp and off-ramp medium for crypto entry and exit, and function as corporate treasury tools for programmable dollar settlement. In emerging markets, stablecoins often represent the most stable and accessible form of money for workers, families receiving remittances, and small businesses, with workers receiving wages and families receiving remittances in stablecoins without US bank accounts. The Bank of England's guidance aims to enhance choice and flexibility for consumers and businesses, with Sarah Breeden, deputy governor for financial stability, stating this represents "a world leading regime" that will safeguard monetary and financial stability as new forms of money emerge.
Despite their stability, stablecoins face several real risks including depeg events, reserve risks, issuer custody risks, and smart-contract vulnerabilities. As reported by The Block, USDC briefly lost its peg in March 2023 when a portion of its reserves sat in a failed bank, demonstrating even well-run stablecoins carry reserve and banking risks. The GENIUS Act in the U.S. and Europe's Markets in Crypto-Assets framework brought strict reserve and disclosure requirements. The Bank of England's approach differs from the U.S. and EU's prescriptive regulations, with Gareth Lodge from Celent noting the U.K. legislation is "based on principles, rather than U.S. and EU based on being very prescriptive." The U.K. guidance represents a pragmatic approach to maintain pace with progress already seen in the U.S., EU and other major jurisdictions, according to Joey Garcia from Xapo Bank. The more flexible U.K. regime paves the way for a robust sterling stablecoin ecosystem, mitigating the risk of the market being completely dominated by U.S. dollar-denominated digital assets and helping safeguard the U.K.'s ambition to remain a leading global hub for financial innovation.
