The U.S. Treasury, under Secretary Scott Bessent, has initiated a strategy to curb rising long-term borrowing costs by doubling its long-end bond buybacks to at least $4 billion per operation. This intervention, which Bessent referred to as a "Treasury twist," occurred after long-bond yields hit their highest levels since 2007. The immediate market reaction saw a sharp decline in yields, with the benchmark 10-year note falling over 5 basis points to 4.647% and the 30-year bond dropping 9 basis points to 5.196%. However, these gains largely reversed the following day, indicating investor skepticism about the long-term effectiveness of the measure.

Financial analysts from firms like Goldman Sachs and ING have expressed caution regarding the lasting impact of these buybacks. Goldman Sachs estimates that while the buybacks, combined with issuance adjustments and balance sheet management, could temporarily compress long-end yields by 20-40 basis points, they are unlikely to reverse the broader upward trend. ING analysts concur, suggesting that while the buybacks may mute the rise in yields, they will not fundamentally alter the trajectory. Deutsche Bank's George Saravelos views the Treasury's actions as a "soft-form" financial repression policy aimed at containing yields, reflecting increasing administration unease.

Market participants and strategists point to several structural issues driving higher long-term rates that buybacks alone cannot resolve. These include persistent fiscal deficits, ongoing inflation uncertainty, and elevated equilibrium real interest rate levels. Additionally, significant capital expenditure pressures from AI infrastructure, data centers, and re-industrialization are contributing to higher long-term borrowing costs. While the Treasury's willingness to intervene might signal future actions, as ING notes, the underlying concerns about national debt and inflation remain unaddressed, limiting the long-term effectiveness of these buyback operations. Goldman Sachs also suggests that a more durable outcome of these interventions might be a lower dollar rather than structurally lower rates.
