The US Treasury’s expanded long-dated bond buybacks aim to stabilise markets as long-term yields hit multi-year highs, but analysts argue they are only a temporary fix for deeper fiscal challenges.
The US Treasury’s decision to expand buybacks of long-dated government bonds has stirred a brisk market response, but several analysts say the move is more a short-term stabiliser than a fix for deeper fiscal problems. Treasury Secretary Scott Bessent said on CNBC that the department may lift the size of each repurchase above $4 billion, after already signalling a larger programme for securities with 10 years or more to maturity.
The policy has come as yields on long-dated Treasuries have pushed to multiyear highs, increasing pressure on borrowers across the economy. Reuters and other outlets reported that the 30-year yield recently touched its highest level in almost two decades, while the Treasury is trying to support a segment of the market that trades thinly, particularly in August. Officials have framed the buybacks as debt management, not stimulus, and said the programme will run from 9 September to 4 November.
UBS said investors should not read too much into the move as a signal of a lasting shift in interest-rate dynamics. The bank argued that the Federal Reserve’s path still hinges primarily on inflation, and that Treasury buybacks may ease pressure at the margin without changing the broader supply-and-demand picture for government debt. UBS also noted that similar interventions in Japan and the UK helped calm markets temporarily but did not permanently lower borrowing costs when fiscal and inflation conditions remained unfavourable.
JPMorgan took a sharper line, saying it sees little evidence of a market malfunction serious enough to warrant a larger intervention. The bank said liquidity metrics in Treasuries remain broadly healthy, and that the more plausible explanation for the programme is political discomfort with rising long-term yields. In its view, the deeper issue is the US fiscal deficit, which it said is near 6% of GDP, with financing needs likely to remain heavy in coming years.
That reading is reinforced by recent IMF research on the Treasury’s earlier liquidity-support buyback programme, which found measurable but modest benefits for trading conditions. The Fund said buybacks can narrow bid-ask spreads, lift prices for eligible securities and ease inventory pressure on dealers, especially when holdings are heavy. But those findings also point to a narrow effect: the operations can improve market functioning, yet they do not remove the government’s need to keep issuing debt.
