Stock futures steadied on Thursday after a selloff during the regular trading day.
Markets were hedging the risk of an earlier rate hike from the Federal Reserve, despite officials vowing earlier in the week that any move was long in the future.
Global stocks fell on Friday, with Asian shares down by the most in nine months, as a rout in global bond markets sent yields flying and spooked investors amid fears the heavy losses suffered could trigger distressed selling in other assets. MSCI's Emerging Markets equity index suffered its biggest daily drop in nearly 10 months and was 2.7% lower, while European shares opened in the red, with the STOXX 600 down 0.7%, recovering from heavier losses earlier in the session. The MSCI world equity index, which tracks shares in 50 countries, was 0.9% lower and heading for its worst week in a month.
