The US bond market just reminded everyone who’s really in charge. Long-dated Treasury yields surged to levels not seen in nearly two decades, and Bitcoin responded exactly how you’d expect a risk-sensitive asset to respond: by whipsawing traders in both directions.
The 30-year Treasury yield peaked at roughly 5.33% around August 17-18, its highest reading since 2007. The 20-year yield wasn’t far behind, climbing to approximately 5.2% in late August. Bitcoin, caught in the crossfire, briefly punched above $81,000 before retracing as yields reasserted their upward pressure.
Bessent steps in with a buyback boost
Treasury Secretary Scott Bessent didn’t wait long to respond. On August 19, he announced a significant ramp-up in buybacks of long-dated Treasuries, doubling the minimum operation size from $2 billion to $4 billion starting September 9.
The problem: it didn’t immediately work. Long-term yields remained stubbornly elevated even after the announcement, suggesting the market’s concerns run deeper than a single policy tweak can address.
Those concerns are rooted in math. US public debt has surpassed $40 trillion, and the fiscal deficit is projected to exceed $1.8 trillion. The buyback increase, while meaningful, looks modest relative to the sheer volume of government paper flooding the market.
Why Bitcoin cares about bond yields
When Treasury yields rise, they create what finance types call a “risk-free rate” problem. A 5.33% return on a government bond suddenly makes speculative assets look less attractive on a risk-adjusted basis.
That dynamic explains Bitcoin’s initial retreat after its push above $81,000. As yields climbed, capital rotated toward the safety and yield of government bonds.
But Bitcoin’s relationship with yields isn’t purely negative. The same fiscal conditions driving yields higher, namely massive deficits and ballooning debt, are precisely the kind of macro backdrop that strengthens the case for Bitcoin as an alternative store of value. When governments are running $1.8 trillion deficits and the national debt crosses $40 trillion, the long-term purchasing power of fiat currency comes into question.
The bigger picture for risk assets
Bessent’s buyback expansion is a signal that the administration is aware of the risks. Doubling the operation size to $4 billion minimum is not nothing, but it’s a band-aid on a structural problem.
For Bitcoin specifically, the key variable to watch is whether yields stabilize or continue climbing. Bitcoin’s brief surge past $81,000 came during a window when yields dipped, offering a real-time demonstration of the correlation at work.
The September 9 start date for expanded buybacks gives markets a concrete catalyst to watch. If the larger operations succeed in capping yields, it could mark an inflection point for Bitcoin and risk assets more broadly.
