May 8 (Reuters) - U.S. stock index futures slipped on Tuesday as investors braced for President Donald Trump’s decision on whether to withdraw from the Iran nuclear deal.
A U.S. withdrawal would tighten economic sanctions on Iran, curtailing the country’s output that could bolster this year’s 13 percent oil rally.
Crude prices were down more than 1 percent - easing from 2014 highs, which had boosted Wall Street in the past two sessions - ahead of Trump’s decision at 1800 GMT (2:00 p.m. ET).
“(Trump’s decision) has been so well covered, it’s probably all in the price by now. And most recent commentary seems to be that after all the bluster, he may only partially withdraw from the deal,” said Frances Hudson, global thematic strategist at Aberdeen Standard Investments.
At 7:19 a.m. ET, Dow e-minis were down 96 points, or 0.4 percent. S&P 500 e-minis were down 11.25 points, or 0.42 percent and Nasdaq 100 e-minis were down 33.5 points, or 0.49 percent.
Shares of Comcast fell 1.5 percent premarket after Reuters reported the cable operator is preparing to make an all-cash offer for media assets that Twenty-First Century Fox has agreed to sell to Disney for $52 billion.
