The Rate Engine

Updated 2026-09-14

What money costs, everywhere.

A public record of interest rates across the United States, Canada and Europe — rebuilt every day from central banks and treasuries. Every figure carries the source it came from, the date it describes, and the moment we retrieved it.

The number nobody publishes

Mortgages cost 1.81 points more than Treasuries

Mortgage rates track the 10-year Treasury, but never exactly. The gap is what lenders charge on top — and it moves for reasons that have nothing to do with the Federal Reserve. It has ranged from 0.97 to 3.26 points since 1990.
