Higher Treasury Yields Amplify Selloffs, Hit Bitcoin

Rising long-term U.S. Treasury yields have disrupted the traditional hedge between stocks and bonds, amplifying recent market selloffs and putting downward pressure on Bitcoin as investors shift into short-dated Treasuries, bills and dollars. Long-duration Treasuries, which previously offset equity losses, have been sold alongside risky assets.

For about two decades, long Treasuries often rose when equities fell. That relationship weakened around 2020 and has continued to diverge. UBS reports the two-month rolling correlation between the S&P 500 and the 10-year Treasury yield at -0.69, the lowest reading since 1996. Duration-the sensitivity of a bond’s price to interest-rate changes-has become a key factor: long Treasuries still provide default protection in nominal terms but carry greater exposure to inflation and policy-rate paths.

Research from AQR finds that shifts between growth-driven and inflation-driven market regimes explain roughly 70% of the long-term variation in the U.S. stock-bond correlation. Since 2022, inflation volatility has dominated market moves. When growth concerns drive markets, stocks and long bonds tend to move in opposite directions; when inflation dominates, higher inflation and higher real yields can push both down.

Market data illustrate the change. The 30-year Treasury yield crossed 5% for the first time since 2007 and traded near 5.1% as of July 16, 2026. A $25 billion 30-year auction earlier in the year cleared above 5%, the highest long-end coupon in about 18 years. Fiscal supply is rising: U.S. deficits are projected to widen from roughly 5.8% of GDP in 2026 to about 6.7% by 2036, and multilateral estimates indicate governments need to raise roughly $18 trillion this year. Foreign demand has thinned as yields elsewhere have risen; Japanese investors sold $29.6 billion of U.S. government and related debt in the first quarter, and term premiums at the long end have increased.

Those supply-and-demand dynamics have encouraged flows into dollars, cash and short-dated Treasury paper while the long end is sold. The shift helps explain episodes in which the dollar strengthens even as long-term yields rise, and why bond-market moves are amplifying shocks across risk assets rather than absorbing them.

Bitcoin has become sensitive to the same macro drivers. Historical patterns show Bitcoin tends to perform when real yields fall, the dollar weakens and financial conditions loosen. Analysis by Societe Generale identifies the 10-year Treasury around 4.5% as a level where rising yields begin to weigh on equities through higher discount rates; other investment-bank work notes that higher yields have compressed the equity risk premium. Because Bitcoin pays no yield and is further out on the risk curve than equities, higher risk-free rates raise its opportunity cost, and falling equities can reduce demand for risk assets. An estimated $15 billion of tokenized U.S. Treasuries are now held on-chain, reflecting demand among some digital-asset investors for sovereign income streams.

Market participants and analysts say long Treasuries could resume a hedging role only if inflation volatility eases, market focus shifts back toward growth, and the Federal Reserve gains room to reduce policy rates. Until such conditions emerge, the combination of higher long yields, rising fiscal supply and thinner foreign demand will influence how fixed-income and risk-asset markets interact.
