The UK just made stablecoin rules cheaper. That's a subsidy, not a safety tweak.
London is trying to buy issuer attention with lower capital costs, and the race with MiCA and Washington is now explicit.

- →The FCA cut its planned stablecoin capital coefficient from 2% to 1%, according to Bitcoin Magazine.
- →That makes the UK rulebook less about consumer protection and more about where issuers choose to live.
- →Watch who files once applications open on September 30, 2026, because domicile is the real vote.
- Stablecoin → A stablecoin is a crypto token designed to keep a steady price, usually by holding cash or safe assets behind it.
- Capital coefficient → A capital coefficient is the share of issued tokens a firm must hold as extra money for losses or shocks.
- MiCA → MiCA is the European Union's crypto rulebook for companies that issue tokens or run crypto services.
- Stress test → A stress test checks whether a firm can survive bad market conditions without breaking.
1% is the number that matters today. Bitcoin Magazine reports that the FCA cut its final stablecoin capital coefficient to 1% of aggregate issued token value. The earlier proposal was 2%. That is not a small edit.
The FCA is not just protecting consumers here. It is pricing London into a three-way fight against MiCA and Washington. The agency made the cut to keep the UK competitive with the EU and emerging US stablecoin law, according to the report.
That makes the rulebook more honest than it looks. Stablecoin issuers care about licensing, bank access, reserve rules, and how much dead money sits inside the structure. If you're Circle, Paxos, or the next non-Tether issuer, that 1% requirement changes the spreadsheet before the first token is issued.
The 1970s money-market fund fight is the clean parallel. Funds did not beat banks because they sounded cooler. They won because rules let them offer a better product while banks sat inside older constraints. The UK is trying to make the same opening, only this time the product is a regulated stablecoin.
The rest of the package is not light. The framework covers trading platforms, custodians, stablecoin issuers, lenders, staking firms, and DeFi groups with clear controllers. Firms must run annual stress tests using their own internal models. They must also send the results to the FCA.
The agency also narrowed some sharper edges. Bitcoin Magazine says stablecoin backing pools can hold up to 5% cash surplus. Redemption forecasting duties were removed. Large trading platforms also shift to industry-led monitoring instead of blanket mandatory on-chain surveillance.
The timeline matters. Pre-application support meetings start in July 2026. The authorization window opens on September 30, 2026, and closes on February 28, 2027. The regime takes effect on October 25, 2027. Existing AML registrations do not convert, so firms must apply fresh.
That last part is the catch. London is offering cheaper capital treatment, but not a free pass. The backing layer just got real, and the domicile fight is now measurable. If serious issuers file in London before they file in Brussels, the FCA's subsidy worked.
The FCA's choice to cut the stablecoin coefficient to 1% is a deliberate bet that Circle-scale issuers will pick London because lower trapped capital beats another nice policy speech.
By February 28, 2027, watch whether at least one major non-Tether stablecoin issuer submits a UK authorization application before naming a MiCA issuer base.
