Bond Yields Fall as Bessent and Warsh Take Center Stage

US government debt prices rose on Monday as bond yields declined across various maturities. This followed a volatile week in which 30-year borrowing costs reached their highest level in nearly twenty years, prompting the Treasury to intervene by increasing its planned buybacks.

The Treasury's next move is now the biggest source of uncertainty for bondholders after Secretary Bessent announced a 'financial initiative' to tackle the country's sizable deficit. Longer-term yields declined on Monday following a report that the Treasury might use its General Account to finance the repurchases.

Nohshad Shah, leading EMEA fixed-income sales at Citadel Securities, described this move as 'financial repression at the margin.' Investors are also closely watching Federal Reserve Chair Kevin Warsh's keynote speech at the Kansas City Fed's annual Jackson Hole symposium on Friday, where he is expected to face questions about the central bank's approach to above-target inflation.

Markets will spend the week anticipating Kevin Warsh's first Jackson Hole speech as Fed Chairman, said Geoff Yu, a senior market strategist at BNY. The latest PCE inflation data due Wednesday raises the stakes, with economists anticipating the annual PCE rate to ease to 3.6% from 3.7% a month earlier.
