April 7 (Reuters) - U.S. stock index futures ticked lower on Tuesday as investors assessed comments that indicated the Middle East conflict could escalate, ahead of President Donald Trump's deadline for Iran to reopen the Strait of Hormuz.
A report said Iran's Kharg Island, a hub of its oil exports, was targeted with several strikes, while Iran's Revolutionary Guards warned neighboring countries of strikes on infrastructure of the U.S. and its allies that could disrupt
energy supplies for years.
The comments come ahead of Trump's Tuesday deadline to reopen the Strait of Hormuz, which Tehran refused. A senior Iranian source told Reuters that talks on lasting peace could begin only after an end to the strikes.
"Either there is a climbdown on the part of Washington or Tehran, which could prompt a major rally in equities and easing of energy prices, or a major escalation with all the implications that might have for financial markets," said Dan Coatsworth, head of markets at AJ Bell.
Global markets have been battered by the conflict that is now in its second month, with investors stuck between comments suggesting an escalation and reports indicating negotiations to end the war.
At 7:17 a.m. ET, Dow E-minis were down 156 points, or 0.33%, S&P 500 E-minis were down 22.25 points, or 0.33% and Nasdaq 100 E-minis were down 114.5 points, or 0.47%.

Wall Street's main indexes closed higher on Monday, marking the fourth consecutive session of gains for the S&P 500 and the Nasdaq, as investors digested the Middle East developments and positioned for the upcoming quarterly earnings season.

On Monday, UBS Global Wealth Management trimmed its S&P 500 end-2026 target to 7,500 from 7,700.
