The week of August 17–21 became a major macro catalyst for digital assets after the U.S. Treasury stepped into the long-end bond market. With the 30-year Treasury yield touching a 19-year high near 5.34%, Treasury Secretary Scott Bessent announced that liquidity-support buybacks of 10- to 30-year debt would at least double, from $2 billion to $4 billion per operation, beginning September 9.
The immediate reaction was a drop of roughly 10 basis points in the 30-year yield, toward 5.19%, which weakened the U.S. dollar and lifted gold. Bitcoin was the standout beneficiary among major risk assets, climbing to about $79,000 and gaining an estimated 20% to 25% within a single week.
Bessent framed the expanded buybacks as market-making in thin August conditions rather than formal quantitative easing. However, traders focused on the signal: the Treasury appeared willing to lean against further long-end yield spikes. When Bessent told CNBC the operations 'could be more than $4 billion per issue,' market participants began calling the policy a 'Bessent put.'
Despite the initial yield decline, long-end yields retraced somewhat on Thursday and Friday as concerns over Hormuz Strait tensions and sticky inflation persisted. Rate-cut probabilities for September and October remained broadly unchanged through the week.
Equities lagged but stabilized on Friday. The S&P 500 added 0.4% to 7,674, the Dow jumped 518 points, or 1%, to 53,277, and the Nasdaq rose 0.4% to 26,180, snapping a five-day losing streak. Still, the weekly performance remained weak, and the bond market continued to drive risk appetite.
For gold, the technical picture shifted meaningfully. XAU/USD broke out of a sideways range and reclaimed its 200-day moving average, trading in the $4,500–$4,600 area after a three-month high. Analysts noted that if gold holds above the 200-day average, momentum could extend toward $4,800–$4,900 before a retracement. A rebound in the 30-year yield above 5.30% or hawkish Jackson Hole signals could push gold back toward $4,400–$4,450.
The macro backdrop matters for crypto because gold and Bitcoin have both been trading as liquidity-sensitive assets. The Treasury buyback signal reduced immediate pressure on long-term yields, weakened the dollar and supported the case for scarce assets. Upcoming catalysts include July PCE and Nvidia earnings on Wednesday, Marvell on Thursday, and Federal Reserve Chair Warsh's first Jackson Hole speech.
If the 'Treasury backstop' narrative holds, risk assets—including Bitcoin—may remain supported. If yields rebound or Jackson Hole delivers a more restrictive tone, the recent rally could face consolidation.
