Turmoil in Treasury bond yields sparks global worries: What to know

Treasury Secretary Scott Bessent attempted to stabilize bond market rates on Thursday, August 20, 2026, but his actions did not yield the desired results, indicating that Wall Street investors remain apprehensive about escalating government debt, substantial borrowing by technology companies, and the Federal Reserve's dedication to combatting inflation.

The yield on the 10-year Treasury note, a crucial benchmark for mortgage rates, climbed back to 4.69%, close to its early Wednesday level before Bessent startled the market by announcing that Treasury would double the size of its bond buyback program to $4 billion per operation from $2 billion. These buybacks aim to decrease the supply of 10-year to 30-year bonds and increase their prices.

When bond prices rise, yields fall. Bessent informed CNBC on Thursday that the bond repurchase program could surpass $4 billion. He added, "We have a big toolkit, so we'll see," and stated that "we believe that the yields don't reflect the underlying fundamentals." Rising bond yields escalate borrowing costs for both consumers and businesses, and the administration has made reducing interest rates a primary objective.

Home purchases have declined this year as mortgage rates have increased. President Donald Trump has persistently called for the Federal Reserve to lower rates, but the persistent increases are primarily driven by financial markets. The 30-year bond yield reached 5.23% on Thursday, slightly lower than the 19-year peak hit on Tuesday.

In addition to the bond buyback, Bessent also announced plans to reveal a new initiative to curtail the government's budget deficit, possibly by Monday. He argued that the deficit will peak this year, partly due to tariff refunds, a temporary factor. Although the deficit has been enormous for years, overall debt surpassed $40 trillion on Wednesday, a staggering record that occurred just months after the national debt first broke past the $39 trillion mark in April.

The Congressional Budget Office projected earlier in the week that the annual gap between government revenue and spending would exceed $2 trillion this year, a remarkable figure beyond recessions. However, Gennadiy Goldberg, head of U.S. rates strategy at TD Securities, claimed that reducing the deficit is primarily the responsibility of Congress, not the Treasury Department.
