The U.S. Treasury Department on Wednesday announced it will more than double its buybacks of long-dated government debt, a surprise intervention to stem a surge in borrowing costs as the 30-year yield reached its highest level since 2007 . Treasury Secretary Scott Bessent authorized the increase of "liquidity support buyback operations" for 10- to 30-year securities to at least $4 billion per operation, up from $2 billion, effective September 9 through November 4 . The announcement drove the 30-year yield down nearly 10 basis points to 5.185% after it had spiked to 5.34% on Tuesday . The Treasury cited "consistent strong sponsorship" in longer-dated sectors . Analysts view the move as a tactical signal to counter bearish sentiment and manage borrowing costs ahead of November's midterm elections, though Evercore ISI noted it changes little about the underlying fiscal fundamentals given the $39.99 trillion national debt .
