About these numbers
Source: the European Central Bank's daily reference rates, one rate each working day, set in the early afternoon in Frankfurt; the US dollar pairs are computed from the euro rates. Daily reference rates from 4 January 1999 to 15 October 2026. Before use, the series was checked for gaps and for jumps that are data errors rather than market moves. Reference rates are set once a day, so a fast day in the market can look different from the close of a trading platform.
