U.S. Treasury Yields and Stocks: A 20-Year Relationship

MacroPublished 2026-10-08Data as of 2026-10-07 close2 min read3 sources

Over 20 years, yield changes and stocks look nearly uncorrelated, but a positive link in 2006–2021 flipped negative from 2022.

KEY NUMBER5.28%U.S. 10-year Treasury yield (Oct 2026, Oct 7 close): within the top 1% of 250 month-ends

BRIEF

  • Over 20 years, months when the 10-year yield rose more than 10bp or plunged more than 25bp saw lower average stock returns.
  • The 10-year yield at 5.28% (Oct 7 close) sits in the top 1% of 250 month-end readings since Jan 2006.
  • Since 2022 the dollar has tended to strengthen as yields rise, so KOSPI in dollar terms is more rate-sensitive than in won.
