Stocks and crude oil prices tumbled, and havens including the yen, gold and Treasuries jumped, as fears deepened about the rising impact of the deadly coronavirus.

With no sign of the disease's containment, traders rushed out of risk assets. Contracts on the S&P 500 index fell more than 1 percent before paring losses. The Nikkei 225 average tumbled over 2 percent at one point. Futures on Chinese shares fell more than 5 percent as the country extended its Lunar New Year holiday. Oil dropped over 2 percent in New York, while 10-year Treasury yields sank to the lowest since October.

The moves came on a day with limited trading options in Asia, as markets were shut in locations including China, Hong Kong, South Korea and Australia due to holidays.
