Interpreting From and To Currency Labels in FX Rates

Article Quant Q&A · Author: Roland

Summary

The document raises a practical question about reading currency metadata from an FX data provider. A user sees a rate associated with the euro and Swiss franc, while the provider labels Swiss francs as the “from” currency and euros as the “to” currency. The displayed value appears to imply the reverse direction, leading the user to ask whether the metadata is wrong or has been misunderstood.

No answer or resolution is included, so the document does not establish how this provider defines its currency fields or whether the reported quote is inverted. It does highlight a useful data-handling issue: currency pair labels and numerical rates must be interpreted together, since a quote can represent one unit of a base currency expressed in quote-currency units, and reversing the pair changes the rate. Users should verify a vendor’s field definitions and quote convention before using rates in analysis. The example is limited to a single provider ticker and date, without broader evidence or a general rule for all FX feeds.

Key ideas

  • Currency metadata labels may appear inconsistent with the displayed exchange rate.
  • An FX quote’s direction determines which currency is expressed per unit of the other.
  • Reversing a currency pair changes the numerical rate, so pair conventions matter in data handling.
  • The document poses the issue but provides no answer about the provider’s specific metadata convention.

# Definition of "From Currency" and "To Currency"?












I'm using a service provider to access FX data, and when requesting the ticker `SWEUBOE` which is the Bank of England's exchange rate for EUR and CHF, I get the following meta information:

```
From Currency Swiss Franc 
To Currency   Euro
```

Yet the value of this rate for today(2017.03.16) is 1.0716 (EUR) which is clearly the other way round, i.e. it's from EUR to Swiss francs(i.e. 1 EUR = 1.0716 CHF).

Is the service provider giving me incorrect information or did I misunderstand something about the "from" and "to" currency?
