About exchange rates
The rates are the European Central Bank’s reference rates, agreed between the central banks at around 2:10pm Central European Time and published at around 4pm on every working day.
They are not trading rates. Banks and bureaux add a margin, usually between half a per cent and three per cent depending on the currency and the amount.
The series has gaps at weekends and holidays, because the central bank sets no rate on those days. The chart skips them rather than repeating the previous rate.
Rates between two non-euro currencies are cross rates computed through the euro, which is the same method the central bank uses.
History goes back to 1999 for most currencies, that is, to the introduction of the euro.
