The US Treasury announced on Wednesday that it will at least double the scale of its bond buyback operations over the coming months, with a sharp focus on the fragile long-duration segment of the market. The announcement triggered a significant pullback in Treasury yields and a sharp rise in equity index futures.

The Treasury Department revealed plans to more than double the size of its buyback program, a move that helped drive bond yields lower amid intense pressure in fixed-income markets. With yields having surged to near 20-year highs, the policy announcement specifically targets the vulnerable long-dated Treasury sector.

Treasury Secretary Scott Bessent is leading the charge to expand buyback operations, concentrating on 10-20 year and 20-30 year maturities. Since late June, these segments have experienced what market participants describe as a "buyer strike," with investors collectively holding back from purchasing.

Where the expansion stands

According to the Treasury's announcement, the government will at least double its buyback ceiling, raising it from $2 billion to a minimum of $4 billion. Following the release, Treasury yields dropped sharply and stock index futures moved considerably higher.

The benchmark 10-year Treasury yield fell 6 basis points to 4.647%, while the 30-year long bond yield tumbled 9 basis points to 5.196%. A basis point equals 0.01%. Yields and bond prices move in opposite directions.

Timeline and rationale

The adjustment will take effect on September 9 and run through November 4. In its statement, the Treasury said: "Expanding the buyback program reflects the Department's desire to provide stronger liquidity support for long-dated nominal Treasuries. The Treasury has continued to receive a substantial volume of high-quality bids in its long-duration buyback operations, which demonstrates stable and robust participation from market players in these instruments."

Essentially, this initiative means the Treasury will step up its purchases of older, long-dated bonds, injecting liquidity into a market segment that has historically seen strong demand. Market analysts point to multiple factors behind the recent yield surge: a rising term premium on Treasury holdings (meaning investors demand additional yield compensation), a shift in the composition of Treasury buyers, and a sharp increase in corporate bond supply from AI-related companies.

Wednesday's announcement signals that the Treasury has taken notice of the liquidity challenges in long-end bonds and is willing to take a more proactive role in the market.
