US Bonds Record Worst Decade in 223 Years, Implications for Bitcoin

Long‑term U.S. Treasury bonds have delivered a negative real return over the past ten years, marking the worst decade in the 223‑year record of bond performance.

Historical performance

Bank of America data shows that 10‑year Treasury bonds lost roughly 2 % per year from August 2016 to August 2026. After adjusting for inflation, the rolling 10‑year annualized return was –5.14 % as of July 2026, a decline worse than the periods following the Civil War, the Great Depression and the 1970s inflationary era. The only comparable stretch occurred in 1803, when the United States borrowed to fund the Louisiana Purchase.

Why returns turned negative

Investors bought bonds at low yields (around 2 % in 2016). Subsequent Federal Reserve rate hikes pushed yields higher, causing bond prices to fall and eroding the fixed coupon payments. The 30‑year Treasury yield stood at 5.25 % and the 10‑year at 4.80 % as of early September 2026.

Bitcoin’s new competitive environment

Bitcoin, trading near $77,934, has slipped about 2 % and sits below its 2025 peak. The cryptocurrency’s appeal has traditionally stemmed from near‑zero cash yields, but the current 5 % Treasury yields present a comparable return target for institutional investors. In the week to September 4, U.S. spot Bitcoin funds attracted $987.7 million, and Bitcoin ETF inflows outpaced other crypto funds.

Outlook

The key question is whether Bitcoin can deliver a 5 % annual return over the next decade, matching the yield offered by long‑term Treasuries. Upcoming inflation data and potential rate moves will influence this comparison.
