US Treasury bonds have delivered their worst decade performance in 223 years, according to Bank of America data. Long Treasury bonds lost approximately 2% annually over the decade ending August 2026, marking the first time this has occurred since 1803. As reported by Bianco Research, this represents the 25th negative 10-year return in the historical record that spans 2,771 monthly readings since 1793. The previous comparable period occurred when Washington borrowed to purchase Louisiana, highlighting the unprecedented nature of this decline. The math is such that bonds pay a fixed coupon, with nothing more to offer investors.
The current environment presents a significant challenge for Bitcoin, which has never faced the 5% yield environment that now exists in US Treasuries. According to Bianco Research analysis, the starting yield has historically determined most of the following decade's returns, with buyers purchasing at 2% earning approximately 2% and those buying at 5.25% historically earning near 5%. This represents a fundamental shift from the cheap money environment that Bitcoin emerged into, when the Federal Reserve cut rates to near zero on December 16, 2008, just 18 days before Bitcoin's first block was mined. The starting yield is the tell, as it has set most of the following decade's return across this data, with history pointing to Bitcoin's ability to earn near 5% annually for a decade.
As of Tuesday, the 10-year Treasury yields 4.80% and the 30-year Treasury pays 5.25%, creating a stark contrast with Bitcoin's current performance. According to BeInCrypto data, Bitcoin trades near $77,934, down approximately 2% and well below its 2025 record. The Federal Reserve's monetary policy has shifted dramatically, with Polymarket traders pricing a September rate hike at 52%, marking a significant departure from the accommodative environment that has historically supported Bitcoin's growth. On this day in 2016, the 30-year Treasury paid just 2.32%, according to Treasury Department records, highlighting the dramatic climb in yields.
Despite the challenging environment, Bitcoin continues to attract institutional capital, with US spot Bitcoin funds pulling in $987.7 million in the week ending September 4, according to Farside data. As reported by BeInCrypto, Bitcoin ETF inflows have outperformed every rival cryptocurrency fund, though this comes as global bond yields have reached levels last seen in 2008. The twist is that the wreckage that makes bonds attractive is the same wreckage Bitcoin buyers cite. Yields are high because Washington borrows on a scale that unsettles lenders, with Federal debt hitting $40.1 trillion on September 3, according to Treasury figures. Oil prices above $100 keep inflation sticky, while the money is not leaving either, creating a dual challenge of high Treasury yields and persistent inflation concerns that continue to support government borrowing costs.
