Current Rate Sources

1. European Central Bank (ECB)

  • The ECB publishes Euro foreign exchange reference rates — i.e., how much one euro is worth in terms of various other currencies. European Central Bank+1
  • These rates are updated daily (on working days) at around 16:00 CET, based on a concertation among participating central banks around 14:10 CET. ECB Data Portal+2Nationalbanken+2
  • They are meant for information purposes only (not necessarily for actual transaction pricing). European Central Bank+1
  • Useful when you want an official “mid-market” benchmark for euro to other currency conversions.

2. Federal Reserve Board / U.S. Department of the Treasury

  • The Fed publishes the “H.10” release of foreign exchange rates: e.g., currency units per U.S. dollar. federalreserve.gov+1
  • The U.S. Treasury also provides “Treasury Reporting Rates of Exchange” for government accounting and official purposes. Bureau of the Fiscal Service
  • These are especially useful for U.S. dollar-based conversions, historical data, regulatory reporting, etc.

3. Bank for International Settlements (BIS)

  • The BIS provides bilateral exchange rates and indicates that it uses the ECB as the primary source for recent daily data, with the Fed complementing. BIS Data Portal
  • Enables cross-country comparisons and time-series consistency.
  • Good for research / economic analysis rather than immediate transaction pricing.

4. International Monetary Fund (IMF) / World Bank

  • The IMF provides tools (such as the Exchange Rate Report Wizard) to download historical and current exchange rate data. IMF
  • The World Bank publishes “Official exchange rate (LCU per US$, period average)” – i.e., local currency units per U.S. dollar. World Bank Data
  • These sources are particularly useful for macro-economic work, cross-country studies, historical comparisons.

5. Central banks / national authorities

  • Many national central banks publish exchange rates (often based on the ECB or other reference rates). For example, Danmarks Nationalbank explains that the ECB sets the reference rate for euro-based currencies, and then DN calculates others. Nationalbanken
  • These are useful if you want a specific country’s official rate or institute.

Choosing the right source depends on your purpose:

  • If you need a benchmark mid-market rate (for reporting, analysis, budget work) → use ECB, BIS, IMF/World Bank.
  • If you need official U.S. dollar-based rates → use Fed H.10, Treasury Reporting Rates.
  • If you need rates for a local currency or specific country → check that country’s central bank or monetary authority.
  • If you are doing actual transactions (e.g., FX trades, bank transfers) → note that commercial banks will apply spreads, margins and may use slightly different rates than these benchmark sources.
