UK FCA Halves Stablecoin Capital Buffer, Easing Issuer Burden

TLDR

• The UK FCA reduced the stablecoin capital coefficient from 2% to 1%, cutting issuer costs significantly.
• The new rule places the UK FCA framework below the EU’s MiCA requirement for stablecoin issuers.
• Stablecoin issuers must still maintain full 1:1 backing with high-quality liquid assets under trust protections.
• The UK FCA removed redemption forecasting obligations, simplifying compliance and reporting requirements.
• Issuers can now hold up to 5% excess reserves, improving liquidity management flexibility.
• The UK FCA scrapped proposed £20,000 holding limits, allowing unrestricted institutional participation.

UK regulators have reduced capital requirements for stablecoin issuers, lowering operational costs and easing compliance burdens. The UK FCA confirmed a new 1% capital coefficient, replacing the previous 2% threshold. As a result, the policy aligns the UK FCA framework below the European Union’s MiCA standards.

UK FCA lowers capital requirements for stablecoin issuers

The UK FCA reduced the capital coefficient for Key Stablecoin Issuers to 1% of circulating value. This change halves the previous requirement and directly lowers capital costs for issuers. Consequently, the UK FCA positions its regulatory framework below the EU’s MiCA threshold.

Moreover, the UK FCA confirmed that issuers must still maintain full 1:1 asset backing. These reserves must consist of high-quality liquid assets held under statutory trust arrangements. Therefore, the UK FCA keeps core protections while reducing operational capital burdens.

In addition, the UK FCA removed redemption forecasting obligations tied to reserve management. Issuers no longer need to estimate and report expected redemption levels. This adjustment simplifies reporting processes and reduces compliance complexity under the UK FCA framework.

The UK FCA also removed limits on individual stablecoin holdings within regulated frameworks. Previously proposed caps would have restricted users to holding £20,000 in stablecoins. However, the UK FCA reversed that plan after consultations with market participants.

As a result, institutional investors can now deploy larger amounts without regulatory constraints. This shift improves the attractiveness of UK FCA-regulated stablecoins for trading and treasury operations. Consequently, the UK FCA framework supports broader capital use cases across financial markets.

Furthermore, the UK FCA introduced flexibility in reserve management by allowing excess backing of up to 5%. Issuers can now hold additional liquidity above the 1:1 requirement without regulatory friction. This change enables smoother liquidity management under the UK FCA rules.

UK FCA framework reflects long-term policy shift

The UK FCA finalized these rules after consultations that began in 2023 with industry stakeholders. Policymakers aimed to create a tailored framework for fiat-referenced stablecoins within domestic markets. Therefore, the UK FCA developed rules that differ from the EU’s standardized MiCA regime.

The UK FCA confirmed that authorization applications will open on September 30, 2026. The final regulatory framework will take effect on October 25, 2027. This timeline provides issuers with a clear path to compliance under the UK FCA structure.

However, lower capital buffers reduce the margin available during financial stress scenarios. While 1:1 backing remains mandatory, issuers now operate with thinner capital cushions. As a result, the UK FCA framework balances cost efficiency with baseline safeguards.
