Government bond yields by country
Narwhal's sovereign bond yields API publishes official daily curves for the United States, United Kingdom, Germany, Japan and Canada. It returns every published maturity for one source date and daily history, with no values filled in. Each country retains its official source's curve type, so measures differ.
