Do long-term Treasury rates line up with inflation and growth fundamentals?
Core argument: As of September 2026, the US 10-year Treasury rate stood at 4.75% while the intrinsic 10-year rate was 5.41%, a gap of 66 basis points.
[The graph shows] the actual inflation rates and real GDP growth rates for the US, going back to 1962, and [the implied] intrinsic 10-year treasury rate (the cumulative column) and actual 10-year treasury rate each year. When inflation surged in 2022, interest rates went up, but since the rates that I am tracking are long term rates, the intrinsic risk free rate vastly exceeded the actual rate that year, but the difference has narrowed over time, and almost dissipated by September 2026 (when the US 10-year treasury bond rate was [5%] and and the intrinsic ten-year rates yielded 5.41%).
