US long-term yields rise again after short-lived Treasury support
After Treasury said it would buy back more debt to ease borrowing costs, 30-year yields fell to 5.18% before rebounding, as debt levels above $40tn and higher oil prices keep investors demanding higher returns.
BBC Business reports US long-term borrowing costs rose again despite a Treasury move intended to lower rates charged by investors in global bond markets. Earlier in the week, the Treasury Department said it would buy back more debt to ease yields on 30-year government borrowing, helping yields fall to 5.18% from an almost two-decade high of 5.34%.
Since then, the yields have climbed again, and economists described the impact as brief. John Canavan of Oxford Economics said the response was short-lived, with traders still focused on large global borrowing needs from governments and corporations, as well as rising oil prices.
The outlet notes the Treasury Secretary Scott Bessent intervention was designed to increase demand for bonds and lower rates, but economists said it also functions mainly as a signaling mechanism. Capital Economics economists added that the Treasury was effectively showing it could step in when yields stay near current levels.
BBC Business also links elevated borrowing costs to broader drivers, including higher oil prices tied to the US-Iran war, heavy cash borrowing by tech firms for AI development, uncertain return timelines, and tax revenues lagging public spending. The report says US national debt passed a milestone of more than $40tn after more than doubling in a decade.
