The U.S. Treasury bought $5.187 billion of long-dated government bonds on Sept. 10, completing the first operation under its expanded program as Bitcoin investors watched for evidence of easier liquidity.
The immediate cross-market readout moved the other way. Treasury’s daily nominal yield curve showed the 10-year yield rising 12 basis points from 4.83% to 4.95%. Its real yield curve, which adjusts the return for expected inflation, showed the 10-year real yield climbing 9 basis points from 2.46% to 2.55%.
Higher real yields raise the return hurdle for a non-yielding asset such as Bitcoin. At the same time, U.S. spot Bitcoin ETFs posted another net outflow of roughly $282 million. The combination separates two mechanisms: Treasury improved a trading outlet for selected older bonds, while the broader cost of money and regulated-fund demand remained unfavorable.
The buyback targeted off-the-run liquidity
Treasury’s official result showed $10.489 billion of securities offered against a $6 billion maximum. It accepted 23 of 40 eligible issues maturing from February 2037 through August 2046.
The $6 billion figure was a ceiling. Treasury describes itself as a price-sensitive buyer in its buyback guidance, allowing it to accept less than the maximum when offers do not meet its criteria. The department retires accepted securities after settlement, managing the composition of its own debt rather than conducting a Federal Reserve monetary-policy purchase.
The operation was designed to support liquidity in off-the-run securities, older Treasury issues that tend to trade less actively than the newest benchmark bonds. Treasury announced in August that maximums for longer-dated nominal buybacks would at least double from the previous $2 billion level beginning Sept. 9.
Research from the Federal Reserve Bank of New York explains why that outlet can help: off-the-run bonds trade less frequently, rely more on dealer intermediation and can benefit from a predictable buyer. The study also describes the program as modest relative to overall Treasury market volumes and dealer holdings.
The accepted amount therefore shows the operation found more than $5 billion of eligible offers at acceptable prices. It does not establish whether bid-ask spreads, dealer capacity or economy-wide financing costs improved. Those outcomes require separate market evidence.
U.S. spot Bitcoin ETFs recorded a net outflow of $282.7 million on Sept. 10, according to Farside Investors.
ETF flows are a signal of demand through regulated funds, rather than proof of one-for-one selling in the spot market. Even with that caveat, the latest outflow offered no evidence that easier conditions were reaching Bitcoin funds.
CryptoSlate’s Bitcoin market page recorded a Sept. 10 reference close of $76,568 before recovering to around $77,800 at press time. That rebound left the asset close to the $76,000 support cluster identified in recent market coverage, while real yields and ETF flows still pointed to pressure.
The next test comes from inflation, yields and demand
The buyback shared the session with several macro forces that can influence bond yields and risk appetite. Those concurrent events prevent a clean causal reading of the Treasury operation.
The Bureau of Labor Statistics reported that final-demand producer prices rose 0.4% in August and 5.4% from a year earlier. Goods prices increased 1.1%, led partly by a 4.2% rise in energy. Persistent pipeline inflation can keep market rates elevated because investors demand more compensation for inflation risk and expect tighter monetary policy.
The European Central Bank added another tightening signal by raising its three key rates 25 basis points on Sept. 10. It also said its asset-purchase and pandemic-program portfolios continued to decline as maturing principal was no longer reinvested.
August U.S. consumer inflation is scheduled for 8:30 a.m. ET on Sept. 11, according to the BLS release calendar. That release is the next immediate test: inflation data consistent with cooling price pressure could pull nominal and real yields lower, while an upside surprise could extend the higher-yield backdrop.

CryptoSlate’s analysis identified accepted purchases and subsequent funding conditions, rather than the headline ceiling, as the meaningful test. The completed purchase now supplies the first half of that test. The second half must come from markets.
A convincing transmission signal would combine lower real yields with evidence that easier cash conditions persist beyond settlement. Renewed spot Bitcoin ETF inflows across more than one session would add a demand-side confirmation. Bitcoin holding above the recent support cluster while those macro and flow measures improve would strengthen the case further.
A continued squeeze would produce the reverse pattern: elevated real yields, repeated ETF outflows and Bitcoin losing support while Treasury continues buying selected off-the-run bonds. Each indicator can move for its own reasons, so the case depends on alignment rather than any single print.
Treasury’s purchase may improve liquidity in a specific corner of the government-bond market. The first post-operation readings showed that benefit had yet to appear in the financial conditions most relevant to Bitcoin.
