Wall Street's main indexes declined about 1 percent on Friday after a raft of weak manufacturing data from the United States and Europe led to a yield-curve inversion, stoking fears of an economic slowdown.
The spread between three-month Treasury bills and 10-year note yields inverted for the first time since 2007. An inverted yield curve is widely understood to be a leading indicator of recession.
US manufacturing activity recorded its slowest pace of growth since June 2017, data from IHS Markit showed.
Germany manufacturing also contracted further in March, showing its lowest reading since June 2013, while factory activity across the euro zone looked equally dismal.
"Right now there are clearly enough signs to be cautious about a number of factors that can potentially cause an economic recession," said Randy Frederick, vice president of trading and derivatives for Charles Schwab in Austin, Texas.
"It doesn't guarantee it," Frederick said, "but if multiple other pieces of data show the same thing then it just increases the chances."
