U.S. stock-index futures declined on Wednesday, amid declines in oil prices, as global stock indexes headed lower after disappointing manufacturing data from China.
WTI futures traded 2 percent lower just around $48 a barrel as of 9:12 a.m. ET.
China's official purchasing managers index (PMI) came in at 50.1 for May, steady on April's level and above a Reuters poll forecast for 50.0. However, the non-manufacturing component fell in May, showing slowing growth in services activity.
In addition, the Caixin China manufacturing PMI, which focuses on smaller companies, fell in May to 49.2, which was below expectations.
