US Treasury Secretary Bessent will disclose the size of an expanded federal debt buyback program; market participants view the number as a lever to curb rising long-term borrowing costs. Financial institutions currently expect a $5–6 bln operation; economists warn a $4 bln package could disappoint and rekindle selling, while a materially larger size would signal the government is more concerned about market instability. Bessent has defended the interventions, calling the recent sell-off a speculative spike warranting policy response and saying his aim is to restore market equilibrium, not to set long-term rates. Ten-year Treasury yields remain near 2023 highs — a direct driver of US mortgage rates and corporate borrowing costs — leaving the announced buyback size an immediate market-moving variable.
