UK Stablecoin Caps: A Market Stifler or a Necessary Precaution?
The UK House of Lords challenges the Bank of England's proposed stablecoin restrictions, arguing they could stifle market growth before it begins. With caps on holdings and significant reserve requirements, the debate centers on balancing regulation with market viability.
The UK House of Lords has thrown a spotlight on a brewing regulatory debate, urging the Bank of England to revisit its proposed caps on stablecoin holdings. This move comes as the UK prepares to set its stablecoin regulatory framework, a key step in its financial evolution, but not without controversy.
The Sequence of Events
In November 2025, the Bank of England unveiled a consultation paper suggesting a regulatory regime for sterling-denominated systemic stablecoins. The core of their plan involved a split backing model, requiring 40% of stablecoin assets to be held as unremunerated deposits at the Bank, with the remainder in short-term UK government debt. The Bank's reasoning was simple: ensure liquidity during large-scale redemptions while maintaining financial stability.
The Lords' report, published on June 3, 2026, highlighted two critical measures: holding limits and asset backing requirements. Individuals would face a £20,000 cap per stablecoin, while businesses would be restricted to £10 million, both framed by the Bank as temporary safeguards. However, the Lords questioned the practicality of these measures, arguing they might hinder the emergence of a fledgling market.
Sarah Breeden, the Bank's deputy governor for financial stability, testified in March, emphasizing the UK's unique banking structure, with banks providing 85% of household credit. Her concern? A rapid shift to stablecoins could disrupt this model, potentially reducing available credit.
The Impact of the Proposed Regulations
The Lords' critique isn't without basis. The proposed restrictions could dampen enthusiasm for creating pound-denominated stablecoins. With the global stablecoin market estimated at $310 billion in 2026, dominated by US dollar stablecoins like Tether and Circle, the UK's stringent caps might be a deterrent.
According to two people familiar with the negotiations, the fear is that these measures could render the UK stablecoin market uneconomic. If firms can't hold enough reserves to generate income, why would they choose to operate under such constraints? This hesitation could lead businesses to favor dollar stablecoins or explore less regulated jurisdictions.
There's also the matter of competitiveness. A nascent UK market, faced with heavy regulations, might fail to attract the necessary players and innovations. The potential benefits, such as enhanced cross-border payments and tokenized settlements, might remain unrealized if businesses opt out.
What Lies Ahead?
The question now is whether the Bank of England will adjust its stance in light of the Lords' recommendations. With draft rules expected mid-2026 and final regulations by year-end, there's a tight timeline for potential revisions. Will the Bank consider a more flexible approach to asset backing, or re-evaluate the necessity of unremunerated deposits?
There's also a growing call for HM Treasury to clarify when a stablecoin transitions from non-systemic to systemic. Without this clarity, issuers remain in limbo, unable to formulate long-term business strategies.
Another aspect to watch is how the Bank addresses remunerations and incentives. While there's minimal demand for interest-paying stablecoins, the treatment of rewards and rebates might influence market dynamics significantly. Reading the legislative tea leaves, the next policy draft will undoubtedly be scrutinized for signs of adaptability or rigidity.
, the balance between regulation and innovation hangs in the balance. The UK's ambition to be a crypto-hub is at stake, and the next few months will be key in determining its path. Will the Bank's stablecoin firewall prove a temporary measure or an enduring hurdle?
