The US Treasury executed its first long-term bond buyback under the expanded program on September 10, 2026. While the $5.187 billion operation was technically well received, bond yields continued higher and spot Bitcoin ETFs kept posting net outflows, underscoring an ambiguous macro signal.
🔑 Key takeaways
- The Treasury bought $5.187B in long-term bonds against a $6B cap
- 10-year nominal yield rose from 4.83% to 4.95% (+12 bps)
- Spot Bitcoin ETFs saw $282.7M in net outflows on Sept. 10
- Bitcoin holds near the $76,000 support cluster, rebounding toward $77,800
- The ECB hiked its three policy rates by 25 basis points the same day
First execution of the expanded buyback program
The US Treasury repurchased $5.187 billion in long-term government bonds on September 10, 2026, according to data relayed by CryptoSlate. It marked the first effective operation since August’s announcement that long-end buyback caps would double from a minimum of $2 billion to a minimum of $4 billion per operation.
Investors had tendered $10.489 billion of bids against a $6 billion maximum cap. The Treasury accepted 23 of 40 eligible issues, with maturities between February 2037 and August 2046. Because the $6 billion cap was binding, the agency behaved as a « price-sensitive » buyer, willing to take less than the maximum when prices did not meet its criteria.
This first half of the test — the Treasury’s ability to actually buy at the announced level — has now been passed. The second half will depend on transmission to actual funding conditions.
Yields and inflation: a paradoxical signal
The immediate yield reaction was counter-intuitive: rather than easing, yields rose. The nominal 10-year yield climbed from 4.83% to 4.95%, a +12 basis point move in a single session. The 10-year real yield — which strips out expected inflation — jumped 9 bps from 2.46% to 2.55%.
That rise in real yields directly lifts the « risk-free rate » benchmark competing with Bitcoin, which pays no coupon. The higher that floor, the greater the opportunity cost of holding BTC, all else equal.
The inflation print released the same day by the Bureau of Labor Statistics did not help. Final-demand Producer Price Index rose +0.4% month-over-month and +5.4% year-over-year in August. Goods prices accelerated 1.1%, supported in part by a 4.2% increase in the energy component.

Bitcoin ETFs: the crack persists despite the rebound
On September 10, US spot Bitcoin ETFs recorded another net outflow of approximately $282.7 million, according to Farside Investors data. These flows primarily reflect demand through regulated vehicles, not direct proof of selling on the underlying spot market.
Bitcoin printed a reference price of $76,568 that day before rebounding toward $77,800 at publication time. The bounce kept the asset close to the $76,000 support cluster flagged in recent technical coverage.
The nuance matters: long-end buybacks are, per New York Fed research, mainly useful for non-benchmark issues that trade less frequently and rely more on dealer intermediation. The program remains modest relative to overall Treasury market volumes and dealer inventories.
Liquidations and selling pressure: leverage normalizing
According to Joel Kruger, market strategist at LMAX Group, the Bitcoin rally was fueled by a combination of expanded Treasury buybacks, falling long-end yields, US dollar weakness, renewed spot ETF demand, and a heavily concentrated short squeeze. Over $2.7 billion in bearish crypto positions were liquidated during the initial push.
In total, crypto liquidations reached $2.99 billion after the Treasury buyback announcement — the eighth-largest liquidation event in history, per Coinglass. Most of those were short positions forced to cover as prices rose.
Yet the prior week had been the best of 2026, with $1.92 billion in inflows into spot Bitcoin ETFs according to SoSoValue — the strongest weekly inflow since mid-October, when Bitcoin was trading near its $126,200 peak. The following Monday added another $337.56 million, and Bitcoin topped out at $81,235, its highest level since May 6.
ECB, dollar and outlook: what to watch
The same day, the European Central Bank raised its three policy rates by 25 basis points and signaled that its asset purchase and pandemic program portfolios would keep shrinking, as maturing principal is no longer reinvested. That hawkish signal reinforces the global nature of the tightening cycle.
On the US side, Treasury Secretary Scott Bessent confirmed plans to deploy nearly $1 trillion from the department’s general account, with the theoretical goal of pushing down the 10-year Treasury yield and the 30-year mortgage rate while reducing publicly held debt.
The critical test remains the August US inflation print, due September 11 at 8:30 a.m. ET. Numbers consistent with easing price pressures could drag nominal and real yields lower, easing the competition for non-yielding assets. A positive surprise, on the other hand, would extend the high-rates backdrop.
Conclusion: two halves of a test to clear
The first half of the test has been passed: the Treasury actually bought $5.187 billion out of the $6 billion authorized, demonstrating operational capacity. The second half will hinge on transmission to market conditions — that is, a durable decline in real yields combined with easier liquidity beyond settlement.
For Bitcoin, the ingredients are still in place: normalizing leverage, an expanded buyback program and a Treasury Secretary committed to bending the curve. But persistent spot ETF outflows and sticky real yields warrant caution. The bullish scenario requires renewed ETF inflows across multiple sessions and Bitcoin holding above the $76,000 support while macro conditions improve. Otherwise, the setup remains that of an expensive but hesitant market.
