Bitcoin’s surge above $80,000 is once again forcing investors to ask a familiar question: is cryptocurrency entering another major bull market, or are markets simply witnessing another powerful but temporary rally? The answer may lie less in Bitcoin itself than in what is happening across global financial markets. Bitcoin has risen sharply in recent days, gaining more than 20% over three days and recording its strongest three-day rally since 2023.
U.S.-listed spot Bitcoin exchange-traded funds also attracted approximately $1.92 billion in net inflows last week, their strongest weekly result since October 2025. These figures suggest that the latest move is not being driven solely by retail speculation. Institutional money is returning to the asset in meaningful amounts.
Yet the most interesting part of the story may be the connection between Bitcoin and the U.S. Treasury recently announced that it would at least double the size of its buyback operations for long-term government bonds, increasing them from $2 billion to at least $4 billion per operation. The purchases will focus on securities with maturities of between 10 and 30 years.
The decision came after a sharp sell-off in long-duration Treasuries pushed the 30-year yield to its highest level since 2007. Technically, this is not quantitative easing. The Treasury is not creating money to purchase assets in the way the Federal Reserve does under QE.
The program is primarily designed to improve liquidity and manage the composition of government debt. Nevertheless, financial markets interpreted the announcement as a signal that Washington is increasingly concerned about high long-term borrowing costs. That interpretation matters for Bitcoin.
When government bond yields rise, investors have a stronger incentive to keep money in relatively safe, income-producing assets. Bitcoin, which does not generate an interest payment simply by being held, must compete with those yields for investment capital. When long-term yields decline, that competition becomes somewhat less intense, and investors may become more willing to move further up the risk curve.
