🔌 FX Providers

LibreFolio downloads exchange rates from central banks — free, and without an API key. A currency pair can have several sources in priority order: if the first one fails during a sync, the next one takes over.

ECB favicon European Central Bank (ECB)
Daily reference exchange rates from the ECB, base currency EUR.
FED favicon Federal Reserve (FED)
FRED database exchange rates, base currency USD.
BOE favicon Bank of England (BOE)
Daily reference rates from the BOE, base currency GBP.
SNB favicon Swiss National Bank (SNB)
Stable monthly average Swiss Franc rates from the SNB, base currency CHF.

📊 Provider Comparison

Each central bank quotes other currencies against its own, the base currency.

SNB (Swiss National Bank) CHF 🇨🇭 Monthly averages, one value per month Swiss-franc pairs, when a monthly rate is enough

🎯 How Routing & Fallback Works

  1. 🛤️ Direct route: one central bank quotes the pair — e.g. EUR/USD from the ECB.
  2. 🔀 Chain route: no bank quotes the pair, so LibreFolio combines steps — e.g. RON/USD as RON → EUR → USD, both steps from the ECB. A chain gets a rate only on days when every step has one.
  3. 🔄 Fallback: with several routes, a sync tries them in priority order and uses the first one that works.
  4. ✍️ Manual: no route for your pair? Save it without a provider and enter the rates yourself in the Data Editor.

You choose the routes when you add a pair, and change them later with the pair's Providers button.

SNB: one rate per month

The SNB publishes monthly averages, dated the 1st of each month. A pair that uses it gets one rate per month, and a chain through the SNB has rates only on those days.
