US Wall Street opened lower on Monday, in the final trading week of the year after major stock indexes fell on Friday.
The sharp sell-off was due to a surge in US Treasury yields after the Federal Reserve signaled it would slow its policy easing in 2025.
The Fed's announcement has investors reassessing their economic outlook.
Higher Treasury yields will increase borrowing costs, putting pressure on businesses and consumers.
This has added to the already volatile market.
Meanwhile, US Treasury Secretary Janet Yellen has stressed the government's debt limit, which could be reached in mid-January.
She urged Congress to act quickly to raise or eliminate the borrowing limit, warning that failure to do so could lead to severe financial consequences.
Investors are bracing for more important data next year that will impact the US stock market.
