Stablecoin risks in the UK — de-pegging, reserves and regulation
Quick answer: Stablecoins are not guaranteed cash equivalents. Issuer reserves, audit quality and market panic all matter. TerraUSD collapsed in 2022. UK stablecoin issuance and custody will face FCA authorisation from 2027. Treat stablecoins as high-risk crypto, not bank money.
Stablecoins aim to hold steady value but history shows pegs can break. UK regulation of stablecoins is expanding under the 2027 regime.
How stablecoins work
Most peg to fiat (USD) via reserves, algorithms or both. USDT, USDC and others differ in transparency and regulation.
When pegs break
TerraUSD lost its dollar peg in 2022, wiping billions. Contagion spread across crypto markets. Holders had no FSCS compensation.
UK regulatory direction
FCA consultations cover stablecoin issuance, custody and redemption rights. Expect stricter reserve and disclosure rules.
Tax treatment
Swapping BTC to USDC is a BTC disposal. Holding USDC does not avoid record-keeping. See stablecoins explainer and DeFi tax guide.
