FAQs
A backward-looking interest rate calculated by compounding the daily euro short-term rate (€STR) in arrears over an interest period such as 1, 3, 6 or 12 months. It represents the realised cost of that period, based on official ECB-published fixings, and is the recommended fallback rate for EURIBOR-linked contracts.
Daily ECB €STR fixings are compounded in arrears over the interest period with a 0-day lookback, so compounding starts on the actual start date of the accrual period. The day count is Actual/360, and if the period starts on a weekend or holiday the preceding business day’s fixing applies for those stub days.

Term €STR is forward-looking: a rate for the coming period, derived from market pricing and known at the start of the interest period. Compounded €STR is backward-looking, based on realised overnight fixings, and the final rate is known only at the end of the period.
For the market-implied path of €STR, see the €STR forward curve.
No. Compounded €STR is a near risk-free, backward-looking realised rate. EURIBOR is a forward-looking term rate reflecting unsecured interbank lending, which includes bank credit risk.
For EURIBOR data, see our EURIBOR swap rates and EURIBOR forecast.
Backward-looking RFRs are robust because they rely on actual transactions rather than forecasts. Compounded €STR is widely used for derivatives and loans that pay interest in arrears, and it is the recommended fallback rate for EURIBOR-linked contracts.
