# Why dollar stablecoins still carry currency risk A dollar stablecoin can hold its dollar peg while changing value in euros, pounds or another currency. If your expenses are in that other currency, you still have foreign-exchange exposure. Peg risk, currency risk and conversion fees are separate: eliminating one does not eliminate the others.

([Stablecoins and CBDCs explained](https://www.bankofengland.co.uk/explainers/what-are-stablecoins-and-how-do-they-work)) - **Local proceeds:** Token quantity, token price and the exchange rate all affect local-currency proceeds. ([USDC Terms](https://www.circle.com/legal/usdc-terms)) - **Market execution:** A quoted reference value differs from the actual third-party sale price and costs. ([USDC Terms](https://www.circle.com/legal/usdc-terms)) ## An unchanged dollar peg, a different local balance Illustrative arithmetic: 1,000 tokens priced at exactly US$1 each are worth €900 at €0.90 per dollar. If the exchange rate becomes €0.85 per dollar, they are worth €850 before fees. The €50 reduction happens without a stablecoin depeg. The inputs are hypothetical, not current exchange rates. In general, local proceeds equal token quantity multiplied by the token’s dollar sale price and the local currency received per dollar, less applicable charges. Evidence: [USDC Terms](https://www.circle.com/legal/usdc-terms) ## Keep three sources of variation separate Currency movement changes the value of the dollar itself against another unit. A depeg changes the token’s market price against the dollar. A spread or service fee changes what the holder actually receives when converting. An interface may combine all three into a single estimated balance. To explain a change, compare the original token quantity, the sale quote and its currency conversion independently.

A rate fixed when an invoice is issued gives a different result from a rate fixed at payment time. This is an explanation of denomination, not a forecast or a recommendation to hold a particular currency. The same arithmetic applies even when the wallet balance never changes.

It could align the reference currency with euro expenses, but issuer, peg, custody, network and conversion risks would still need separate assessment. Matching the unit is only one part of the analysis.
