The UK House of Lords Financial Services Regulation Committee has published a letter publicly asking the Bank of England to reconsider its proposed holding limits for systemic stablecoins: no more than £20,000 per stablecoin for individuals, and no more than £10,000,000 for businesses. According to CoinDesk’s reporting, the committee believes this cap could suppress the development of the UK stablecoin market, running counter to the government’s goal of building the UK into a crypto asset hub. It’s worth clarifying that this is the central bank’s regulatory framework for the issuance and holding of systemic stablecoins, a separate track from the stablecoin legislation led by the Treasury and the FCA. The Bank of England’s related discussion paper can be found on its official systemic stablecoin discussion paper page; the specific limit figures currently appear mainly in the central bank’s subsequent consultation proposals, and the official final documents should be treated as authoritative.
This news is about “holding,” not “spending”
Let’s clear up the point readers most easily confuse: the £20,000 cap governs how much systemic stablecoin you “hold,” not how much you “spend on your card.”
The actual workflow of most USDT virtual cards is: you top up your card account with ₮ → at the point of sale it’s converted to fiat (GBP/EUR/USD) in real time → the merchant receives fiat. The USDT sitting in your account usually stays there only briefly, nowhere near £20,000. So for UK users who use their cards day-to-day, this news won’t produce any noticeable change within 7 or 30 days — cards still work, exchange rates are calculated the same way, and limits stay as they are.
The groups actually affected fall into two other categories:
- People treating their USDT card account as a stablecoin savings account: if you’re in the habit of holding tens of thousands of pounds’ worth of stablecoin in your card long-term, issuers may eventually be forced to split balance limits should the cap take effect.
- Issuers wanting to launch a “UK-domestic compliant stablecoin card”: the stricter the limit, the harder the business model for a domestic compliant stablecoin becomes. This indirectly affects players like Wirex and Crypto.com Visa, which already operate in the UK/Europe and might pivot toward GBP-stablecoin products — not that their current products have a problem today, but the design space for their “next-generation products” is being framed by this.
If you’re currently choosing a card, mainstream channels remain the steadiest option for UK users — see our 2026 Top 5 USDT Cards and lowest-fee card comparison for reference.
Historical parallel: this isn’t the first time a central bank has floated a “holding ceiling” for stablecoins
The Bank of England’s £20,000 approach isn’t unprecedented.
- The 2023 central bank discussion paper: back at the systemic stablecoin discussion paper stage, the Bank of England already floated the concept of a personal holding limit, with a range of £10,000 to £20,000 at the time, on the grounds of preventing large-scale deposit migration from the banking system into stablecoins (disintermediation risk). The current proposal continues the same logic — what’s changed is that the House of Lords has now explicitly pushed back — a check-and-balance has emerged at the legislative stage.
- The 2023 USDC de-peg incident: that crisis exposed the issue of “stablecoin reserve quality” (Circle’s exposure at Silicon Valley Bank), and the regulatory response focused on reserve transparency. This UK move focuses instead on holding scale — the regulatory concern has shifted from “is the coin itself stable” to “will the people holding it disrupt bank deposits,” an entirely different dimension of concern.
- The EU’s MiCAR: MiCAR sets transaction-volume thresholds for “significant e-money tokens” not denominated in euros, restricting issuance beyond that threshold — the same “regulate it once it gets big” logic. But MiCAR limits transaction volume at the issuer level, while the Bank of England limits balances at the holder level. One is on the card-issuance side, the other on the card-user side.
The common thread: both are defensive regulatory reactions to the “systemic importance” of stablecoins. The difference: the UK’s limit here reaches directly down to the individual wallet level, making it, among major markets, the constraint design that comes closest to the end user.
Compliance boundary: currently a “draft-stage negotiation,” not an already-effective rule
Readers should be clear on one point: the £20,000 cap has not taken effect; it’s currently at the negotiation stage between the central bank’s proposal and the parliamentary committee.
- Explicitly permitted: holding and spending mainstream stablecoins (including USDT) within the UK, with no current hard cap on individual holdings.
- Legal gray area: future systemic stablecoins (GBP stablecoins deemed by regulators to be systemically important) may fall under the limit framework — but neither “which coins count as systemic” nor “whether £20,000 is the final figure” has been settled.
- Explicitly prohibited: none.
The UK itself has no blanket ban comparable to China’s. Readers wanting the broader regulatory context can refer to our UK compliance guide; if your assets or identity are more closely tied to the EU side, our EU compliance guide offers a fuller overview of the MiCAR framework.
Four milestones worth watching next
- The Bank of England’s formal response: after the committee’s letter, the central bank will typically state its position in a subsequent consultation paper or hearing. Watch whether it softens the £20,000 figure.
- The next consultation paper: the actual limit figures and implementation timeline will be written into the formal consultation paper, not media summaries. Treat the central bank’s official page as authoritative once published.
- Progress on FCA and Treasury stablecoin legislation: the central bank governs systemic issuance, the FCA governs issuer conduct rules, and the two tracks ultimately need to fit together into a complete rulebook. Whichever lands first determines the compliance path for card issuers.
- Whether GBP stablecoin products emerge: a strict cap could delay domestic GBP stablecoin cards; a looser one could accelerate them. This is a good indicator to watch for issuer movement.
Editorial recommendations
Match the advice to your situation — there’s no one-size-fits-all answer:
- Everyday UK USDT card users: no action needed. This news won’t affect your spending, exchange rates, or existing limits within the foreseeable 90 days.
- Users treating their card account as long-term stablecoin savings: consider keeping large stablecoin balances on an exchange or in an on-chain wallet rather than in a card balance — this is simply better fund management practice regardless of this news, but it’s a timely reminder.
- Users planning to apply for a new UK/European compliant stablecoin card: feel free to apply for existing products as usual, but there’s no need to delay your decision waiting for a new GBP-stablecoin card — legislation will take at the very least several months to land, and the details are far from settled.
- Industry readers tracking issuer moves: add the Bank of England’s next consultation paper to your watch list — that’s where the final figures will actually be settled.
Regulation is tightening its framework, but what’s tightening is “how the central bank regulates systemic stablecoins,” not “whether you can use a USDT card to buy things.” Don’t conflate the two.
