Tether (USDT) and the UK: what’s actually going on
If you’ve ever sold Bitcoin and didn’t want to leave the crypto market entirely, you’ve probably ended up in USDT. Tether is a stablecoin pegged to the US dollar, a token that’s supposed to be worth about $1 at all times. Traders use it to shuffle money between exchanges, but it has also become a way to hold dollars without a US bank account, or to send money across borders without waiting on the banks. That scale is exactly why Tether is also one of the most scrutinised companies in the industry.
How it holds the peg
On paper, the mechanism is simple. Tether issues tokens and holds assets to back them. When demand rises, more tokens are minted; when customers redeem directly with the company, tokens are taken out of circulation. According to Tether, the reserves are mostly US Treasuries, plus cash equivalents and other investments. Its Q2 2026 attestation put roughly $184.6 billion of USDT in circulation at the end of June, which makes the company one of the larger holders of US government debt.
Why people still argue about it
The doubts have always been the same: is every token really backed, and how much does the company tell us? Tether has faced action from US regulators and now publishes regular attestations from an independent accounting firm. But an attestation isn’t a full audit, and that gap is where much of the debate still lives. CEO Paolo Ardoino says the company has been treated unfairly, pointing to its cooperation with law enforcement and its ability to freeze addresses tied to criminal activity.
Here’s my view. The freezing argument is fair, and it does show Tether can act when it wants to. But it’s an answer to a different question. Whether the reserves are there is the thing holders care about, and a company this large, sitting on this much of the Treasury market, should be able to clear the bar of a full audit. Years of “trust us, we’re getting better” isn’t the same as proof.
Where the UK stands
The UK’s rules for cryptoassets are changing fast. The Financial Conduct Authority has set out requirements for trading, custody and the issuing of qualifying stablecoins. Firms can already apply for authorisation, and the full regime takes effect on 25 October 2027. Stablecoins issued in the UK will mostly fall under FCA supervision, and a sterling stablecoin that becomes important enough to the payments system could also come under the Bank of England, which published its proposed framework for systemic stablecoins in 2026, covering reserve assets and users’ right to redeem.
None of that automatically makes USDT a regulated UK product. The framework separates stablecoins issued in the UK from foreign ones that British customers simply buy or trade, and Tether, a dollar stablecoin issued abroad, sits in the second group. How it’s treated will depend on how it’s offered to UK customers and how the exchanges and other firms handling it fit under FCA rules.
I think that’s a sensible approach in principle, because it avoids pretending the UK can regulate a foreign issuer directly. The risk is that the weak point simply moves to the exchanges, and a casual user who sees “FCA-authorised platform” may assume the coin itself has been vetted. It hasn’t.
USDT is not a dollar in your bank account
Even though USDT trades around $1, it isn’t the same as a dollar in a UK bank account. A deposit is a claim on a regulated bank and, in many cases, is covered by deposit protection. A stablecoin is a claim on its issuer, on whatever terms the issuer sets. Its stability rests on the quality and liquidity of the reserves, on the ability to process redemptions and, in the end, on market confidence. USDT has stayed close to its peg for most of its life, but “most of the time” isn’t “always”.
Why it matters beyond crypto
Because so much of Tether’s reserve sits in US government securities, growth in USDT means extra demand for dollar assets. For people in countries with high inflation or currency controls, it’s a practical route to dollars. This is why stablecoins are increasingly discussed as part of the future of international payments rather than just a trader’s tool.
My bottom line: I think USDT is genuinely useful, and I wouldn’t tell anyone to avoid it. But I’d treat it as a tool for moving and parking money, not as a substitute for cash in a regulated bank. For UK users, the real test over the next few years is whether the new regime makes the risks clearer, or just makes them look smaller.
