The UK’s Financial Conduct Authority has finally delivered clarity on a hotly debated issue: stablecoin issuers cannot pay interest to holders. This ban, set to take effect with the new regulatory framework, forbids any direct or indirect transfer of earnings from the assets backing stablecoins to tokenholders. It’s a sharp move that reshapes how stablecoins will function in the UK market.
Why No Interest Payments?
The FCA’s final policy, released in June 2026, draws a firm line: stablecoin issuers cannot pass through income generated by the reserve pool. Whether it’s called interest, a reward, or any other form of yield, it’s off limits. This includes straightforward monthly interest payments as well as more subtle schemes like loyalty bonuses that increase token balances based on holding duration. The regulator’s goal is to keep stablecoins simple and stable, avoiding the riskier dynamics that interest payments could introduce.
Issuer Rules and Backing Assets
Issuers are allowed some leeway in how they manage their backing portfolios. Up to 70% can be invested in short-term UK government debt, while the rest must reside in central bank deposits that don’t yield interest. This setup lets issuers retain any returns as a buffer to strengthen stability, rather than passing them on. also a temporary issuance cap is set at £40 billion per coin, connected to Bank of England oversight, to limit systemic risk. Issuers must also maintain minimum own funds of £350,000 and meet prudential standards adjusted to a 1% calibration.
Upcoming Tax Changes and Market Impact
The tax landscape will shift starting April 2027. HMRC plans to treat any interest-like returns from eligible stablecoins as savings income, potentially affecting around 1.2 million individuals. While stablecoin holders won’t receive interest directly, those who earn yield through other means could see new tax obligations. This aligns with broader efforts to regulate crypto assets more tightly and integrate them into existing financial frameworks.
The FCA’s approach contrasts with some global markets where stablecoins can yield returns, creating a unique environment in the UK. It also intersects with ongoing regulatory moves, like the SEC’s crypto rules in the US, which shape how digital assets evolve worldwide. The UK’s clear stance signals a focus on consumer protection and financial stability, even if it means limiting some innovation.
