UK Drops Limits on Sterling Stablecoin Holdings: £40 Billion Ceiling Introduced

The Bank of England's latest move has ruffled a few feathers in the stablecoin world. Gone is the unpopular £20,000 cap on individual sterling stablecoin holdings. Instead, the UK has set a new £40 billion total market limit for each systemic sterling stablecoin. This pivot replaces constraints on personal and business holdings with a broader cap on market size.

Businesses and individuals can now hold as much regulated pound stablecoin as they like, taking a step away from strict wallet-level limits. However, the £40 billion market ceiling remains a point of contention. While the Bank of England labels this cap as "temporary," it marks the UK as an outlier. Neither the US nor the EU have placed similar restrictions on their currency-based tokens.

Economic dynamics are complex. Stablecoin issuers can now earn more from reserves, with 70% of backing allowed in interest-yielding UK government debt. Lowering the non-yielding reserve requirement from 40% to 30% sweetens the deal for issuers. Yet, the cap still stifles growth, making sterling stablecoins potentially less attractive than dollar or euro counterparts.

The real kicker? Demand. UK consumers have fast, free domestic transfers via Faster Payments, so why switch to a sterling stablecoin? And globally, dollar tokens dominate, with 98% of stablecoins in circulation denominated in dollars. The deep liquidity and lack of a ceiling for dollar tokens make them hard to rival.

While the UK aims for a conservative, trusted framework, this move might not ignite the sterling stablecoin market. The Bank of England needs to strike a balance between regulation and growth. If the market can demonstrate stability and demand, there's hope for revisiting the ceiling.
