U.S. Bonds Suffer Worst Decade In 223 Years As Bitcoin Faces 5% Yield Test

U.S. bonds have posted their worst decade in 223 years, with long Treasuries losing about 2% a year over the 10 years to August 2026 and the rolling 10-year annualized real return at -5.14% as of July 2026. The stretch has revived debate over Bitcoin’s appeal as Treasury yields rise, according to BeInCrypto, with the 10-year at 4.80% and the 30-year at 5.25% on Tuesday. Bitcoin traded near $77,934, while U.S. spot Bitcoin funds took in $987.7 million in the week to September 4.
