Sometime during the past eighteen months, a decision that will influence the flow of digital money in Britain for the next ten years was made in a small, somewhat unglamorous building on Threadneedle Street. When you pass it on a weekday morning, you’ll see people in suits pushing through revolving doors while holding coffee cups and discussing reserves and redemptions in the same manner that bond traders used to discuss gilts. Theatrical announcements have never been made at the Bank of England. However, the rulebook that is being developed within it, along with the FCA located further west along the river, is one of the most significant financial regulations that Britain has attempted in a long time.
Forty percent is the headline figure that everyone keeps returning to. Systemic stablecoin issuers will be required to park at least 40% of their backing assets at the Bank itself, earning nothing on them. These issuers must be large enough and widely used enough to make a Treasury official’s eyebrows twitch. Short-dated sterling government debt may hold the remaining sixty. It sounds almost boring and technical. In actuality, it is the type of regulation that determines whether a stablecoin company can make money in London or discreetly move to Singapore.

Speaking with industry insiders gives the impression that the UK is attempting to do two things at once that don’t quite fit together. Speeches at the chancellor’s level consistently guarantee that Britain will be the preferred location for cryptocurrency. The actual regulations resemble a stress-test memo from the Bank of England. Redeeming in particular is a new market practice for which providers will need to create entirely new systems, according to the KPMG note on the proposals. reconciliation every day. T+1 redemption without a minimum. Fiduciary duties are owed by the issuer as trustee of a statutory trust that holds the backing assets. It is comprehensive. Additionally, it is the strictest framework in any major market by the majority of measures.
If you recall 2022, you can understand the regulators’ logic. Within a week, TerraUSD disappeared. For a moment, Tether dropped to 94 cents. It appears that Threadneedle Street has learned that a stablecoin that isn’t truly stable has the potential to ensnare many common people. On the opposite side of the Atlantic, the Trump administration learned that a US dollar CBDC was completely off the table and that the GENIUS Act should allow innovation to flourish. Stablecoin issuers are caught between two regimes, two points of view, and two doors.
The asymmetry ingrained in the British strategy is difficult to ignore. One of the world’s strictest regulations will apply to a stablecoin issued in the UK. A stablecoin issued abroad that is accepted on a UK trading platform won’t. This appears to be clearly read by issuers. As of right now, the UK does not issue any stablecoins. The regulatory sandbox is prepared, and the FCA has opened pre-application meetings via its Principal Application System. It’s still unclear if anyone will fill it.
In the spring of 2026, the House of Lords heard testimony from Circle, Mastercard, Revolut, Chainalysis, and the Deputy Governor. If only because the witnesses repeatedly brought up the same tension, the transcripts are worth reading. Everyone wants to be safe. The expense is something that no one really wants. You get the impression that October 2027 isn’t the true test as you watch this play out. It’s if anyone has bothered to apply by then.
