How this rate is set

Rates on this page come from open.er-api.com, an aggregate of central bank and commercial feeds, refreshed hourly. Not every currency on this site has a euro reference rate behind it, and this pair does not: it is sourced from that aggregate feed alone. Between refreshes the figure shown is the most recent value received rather than a live quote.
