Traders will closely watch a weekly update on U.S. crude inventories that is due at 10:30 am ET.

2. Stock market movers -- Metlife, Yum Brands, Ford, BP, VW: Metlife (MET) shares surged more than 7% Tuesday night after The Wall Street Journal reported it's planning to separate or sell its U.S. life insurance operations. KFC and Taco Bell owner Yum Brands (YUM) was trading 3% higher premarket, while Ford (F) shares dropped 3%.

BP (BP) shares are up 2.5% a day after it slashed another 4,000 jobs amid low oil prices.

Volkswagen (VLKPY) shares are up more than 2.5% despite ongoing confusion surrounding the emissions scandal and whether the auto giant "lied" to regulators.
