The Treasury Department's bond buyback announcement briefly stemmed a selloff, but yields quickly rebounded. Treasury Secretary [PERSON_NAME] doubled buybacks for long-term bonds, causing a rally that [PERSON_NAME] of Annex Wealth Management called a superficial fix. The 10-year yield settled at 4.737%, up from 4.695% a week earlier.

The $31.5 trillion Treasury market faces deeper concerns: stubborn inflation, $40 trillion federal debt, corporate borrowing for AI, and uncertainty around new Fed Chairman [PERSON_NAME]. Yields on 30-year bonds topped 5.3%, highest since 2007, pushing mortgage rates near 7%.

Analysts debate drivers—AI issuance, deficit at 6% of GDP, Fed communication. [PERSON_NAME]'s intervention worked instantly but faded as gross debt hit $40 trillion. Critics warn the buyback creates a perceived backstop without commitment.

Markets await [PERSON_NAME]'s speech at the Kansas City Fed symposium for clarity on rate outlook. Portfolio managers say he must signal willingness to hike if inflation warrants, or risk losing patience.
