Treasury Buys $5.2bn of Long Bonds as Yields Climb and Bitcoin ETFs See Outflows

The US Treasury bought back $5.187bn of long-dated government bonds on 10 September, completing the first operation under its enlarged buyback programme.

The market response gave little support to the idea that easier liquidity is reaching Bitcoin. Long-term yields rose on the day and US spot Bitcoin exchange-traded funds recorded another net outflow, CryptoSlate reported.

The operation

Treasury received $10.489bn of offers against a $6bn maximum and accepted 23 of 40 eligible issues, with maturities running from February 2037 to August 2046.

The $6bn figure was a cap, not a target. Treasury's buyback guidance describes it as a price-sensitive buyer, so it can take less than the maximum when offers fall short of its criteria. Securities it accepts are retired after settlement.

That makes the exercise a debt-management tool rather than a Federal Reserve purchase made for monetary-policy reasons. Its purpose is to improve liquidity in off-the-run securities, the older issues that change hands less often than the newest benchmark bonds.

In August, Treasury announced that from 9 September the cap on buybacks of longer-dated nominal securities would rise to at least twice its previous $2bn level.

Research from the Federal Reserve Bank of New York has found that off-the-run bonds trade less frequently, lean more heavily on dealers and benefit from a predictable buyer, while also describing the programme as modest relative to market volumes. The accepted amount shows Treasury found enough offers at acceptable prices; it does not show whether bid-ask spreads, dealer capacity or financing costs improved.

Yields moved the other way

Treasury's own daily curves showed the 10-year nominal yield up 12 basis points, from 4.83% to 4.95%. The 10-year real yield, which adjusts for expected inflation, rose 9 basis points from 2.46% to 2.55%.

Real yields are the more relevant gauge for Bitcoin. A higher inflation-adjusted return on government debt raises the bar for any asset that pays no income, making it harder to argue that holding Bitcoin carries little opportunity cost.

On the same day, US spot Bitcoin ETFs posted a net outflow of $282.7m, according to Farside Investors. ETF flows capture demand through regulated funds rather than offering a one-for-one measure of spot selling, but they remain a closely watched indicator of institutional appetite.

Bitcoin's reference close on 10 September was $76,568, based on CryptoSlate's market data. It had recovered to about $77,800 at the time of reporting, near a support cluster around $76,000 highlighted in recent coverage.

The day's numbers separate two mechanisms. Treasury eased trading in one narrow segment of the bond market, but borrowing costs more broadly and demand for regulated Bitcoin funds both remained a headwind.

A hawkish macro backdrop

Other data pointed the same way. Bureau of Labor Statistics figures showed final-demand producer prices rising 0.4% in August and 5.4% from a year earlier, with goods prices up 1.1% and energy up 4.2%. Persistent inflation in the production pipeline can keep interest rates high.

In Europe, the European Central Bank raised its three key interest rates by 25 basis points on 10 September. It also continued to shrink its asset-purchase and pandemic-programme portfolios by no longer reinvesting maturing principal.

What would change the picture

The next immediate test was the August US consumer price index, due at 8:30am Eastern time on 11 September.

Beyond that, CryptoSlate's analysis set out what a genuine liquidity signal for Bitcoin would require:

• Lower real yields, with evidence that easier cash conditions last beyond settlement.
• Renewed inflows into spot Bitcoin ETFs over more than one session.
• Bitcoin holding above its recent support while macro and flow measures improve.

The opposite combination, with real yields staying elevated, repeated ETF outflows and Bitcoin losing support even as Treasury keeps buying, would suggest a continued squeeze.

No single indicator settles the question. The case for liquidity reaching Bitcoin depends on several of them lining up at once.
