NEW YORK — Wall Street’s sell-off hit a new low Thursday after President Trump’s escalating trade war dragged the S&P 500 more than 10% below its record, which was set just last month.

In the bond market, Treasury yields climbed to regain more of their losses from recent months sparked by worries about the U.S. economy’s strength. The 10-year Treasury rose to 4.30% from 4.28% late Tuesday and from 4.16% at the start of last week.
