The 10-Year Treasury Yield Today
Live yield, the 5-day move, key levels, and the link to mortgage rates. Updated 2026-08-21.
Why the 10-Year drives mortgage rates
The 30-year mortgage is priced off mortgage-backed securities, and MBS trade at a spread over the 10-Year Treasury. So the 10-Year is the single best real-time proxy for where mortgage rates are heading. When the 10-Year yield rises, mortgage rates usually follow within a day or two; when it falls, rates ease. The support and resistance levels above are the near-term floor and ceiling the yield has been respecting.
