# Stablecoins explained for UK holders

Stablecoins are cryptoassets pegged to another asset (often the US dollar or pound). HMRC treats them like other tokens for tax — swapping USDC for bitcoin is a disposal. Systemic stablecoins may face Bank of England and FCA oversight.

## Key facts
- HMRC does not exempt stablecoins from CGT — gains on disposal may still be taxable.
- The Bank of England regulates systemic payment systems including certain stablecoin arrangements.
- Not all stablecoins maintain their peg — 'de-pegging' events have occurred.
- FCA financial promotions rules apply to stablecoin marketing.

## Types of stablecoin

Fiat-backed stablecoins hold reserves in bank accounts. Crypto-backed coins use other digital assets as collateral. Algorithmic stablecoins use code to manage supply — these have failed historically. Understand what backs a token before holding it.
## UK regulatory direction

The UK government and Bank of England are developing regimes for stablecoins used for payments. Firms issuing or facilitating stablecoin payments may need authorisation as the framework develops.
## Tax when using stablecoins

Converting bitcoin to a stablecoin is a CGT disposal. Moving between stablecoins is also a disposal. Holding stablecoins with no disposal creates no CGT event, but interest-like rewards may be income.

## FAQs
### Are stablecoins the same as cash?

No. They are cryptoassets, not bank deposits. FSCS does not protect stablecoin holdings.
