NEW YORK — U.S. government borrowing costs climbed to their highest point since 2007 this week, with the 10-year Treasury yield reaching 5.04 percent. The sell-off in the Treasury market deepened, pushing long-term yields higher globally for months.
The 10-year Treasury yield, a benchmark for U.S. borrowing, later retreated from its 5.04 percent peak. Yields on 30-year U.S. Treasury bonds also reached their highest levels since 2007, during broader pressure on sovereign debt.
Global government bond yields have risen due to persistent worries that inflation, fueled by a rise in oil prices, will necessitate higher interest rates. The global benchmark wholesale oil price reached over $109 a barrel on Tuesday, up from approximately $86 at the end of August.
This oil price increase follows renewed concerns about Saudi Arabia's ability to export crude, during rising tensions in the region after the start of the U.S.-Israel war with Iran. Higher energy costs directly contribute to inflationary pressures across economies.
Investors anticipate U.S. Federal Reserve Chair Kevin Warsh will raise interest rates to combat this inflation. However, U.S. President Donald Trump opposes a rate hike, maintaining that lower rates are essential for economic growth. President Trump previously had disagreements with Warsh's predecessor, Jerome Powell, over Powell's decision not to cut rates.
Higher interest rates and inflation typically increase the yields bond investors demand on government borrowing. These yields also serve as an indicator of investor confidence in a government, with rising yields suggesting reduced faith.
Treasury Secretary Scott Bessent previously announced expanded buybacks of long-dated government debt in an effort to reduce yields, an intervention he described as successful. Despite these efforts, long-term yields continued their ascent.
Carol Schleif, chief market strategist at BMO Wealth Management, said bond markets have signaled the need for higher interest rates for weeks. Schleif said that while the increase in borrowing costs this year has been orderly, rates could remain elevated if geopolitical tensions and high energy prices continue to be market drivers.
The sustained rise in long-term borrowing costs places new pressure on the economy, increasing the cost of loans for consumers and businesses. Public finances face strain from the higher cost of servicing government debt, as markets grow more anxious over inflation and government deficits.
