Treasury Secretary Scott Bessent's announcement to double the government debt buyback program, from $2 billion to "at least" $4 billion per operation, was intended to calm the bond market, specifically targeting longer-duration bonds (10- to 20-year and 20- to 30-year). This move initially led to a dip in yields, with the 10-year Treasury note falling 5.7 basis points to 4.647% and the 30-year bond dropping 9 basis points to 5.196% on Wednesday. The initiative, scheduled from September 9 to November 4, aims to provide liquidity to a stressed market segment.

Despite this immediate effect, the long-term effectiveness of Bessent's strategy remains uncertain. On Thursday, the 10-year Treasury note's yield rebounded to 4.69%, nearly its level before the announcement, indicating persistent investor worries about burgeoning government debt, heavy tech borrowing, and the Federal Reserve's commitment to fighting inflation. Analysts like Krishna Guha of Evercore ISI suggested the move could temporarily deter short-selling and attract buyers, but fundamentally changes little regarding the "tidal wave of hyperscaler debt" and large government deficits.

Several financial experts have expressed skepticism. Joe Brusuelas, RSM's chief economist, criticized the move as a short-term political play aimed at the upcoming election, potentially hindering the Federal Reserve's inflation control efforts by artificially suppressing yields. Mohamed El-Erian noted on X that the planned purchases are "small in both absolute terms and relative to net issuance," suggesting it's more about "yield curve control." Peter Boockvar of One Point BFG Wealth Partners clarified that it's a "rearrangement of the maturity schedule of Treasuries," not a debt paydown. ING even compared Bessent’s $4 billion bond plan to “rearranging deckchairs on the Titanic” given the US national debt of $40 trillion.

Investors and analysts from JPMorgan Chase and Co., Jefferies LLC, and PGIM Inc. have warned that such unpredictable debt management moves by the US Treasury could lead to higher borrowing costs. They argue that surprises, like the recent buyback boost, increase the term premium—the extra compensation investors demand for holding government debt due to perceived risks. The market's recent volatility has been attributed to a higher term premium, a changing Treasury buyer base, and increased corporate debt, particularly from the AI sector.

President Donald Trump, when asked on Wednesday if Americans should be worried about the bond market, responded, "No, I don't think so." However, the overall sentiment among analysts suggests that while Bessent's intervention might offer a temporary "circuit breaker" for the global bond slump, it may not address the underlying fiscal challenges and could even complicate the Federal Reserve's monetary policy objectives.
