April 23 (Reuters) - Wall Street futures slipped early on Thursday, with investors hesitant to extend the recent equities rally in the absence of clearer signals on the U.S.-Iran war.
Iran seized two ships in the Strait of Hormuz and demanded that the U.S. lift its naval blockade, which remains in effect even after President Donald Trump extended the ceasefire indefinitely.
Investors keen to look past war-related risks have shown strong resilience in recent days, but some fatigue has set in, leading
to brief episodes of risk aversion as they await a clearer sense of how the conflict may ultimately be resolved.
With oil prices over $100 a barrel, the risk of an inflation flare-up also remains.
"Even in the event that the Middle East conflict eases and shipping resumes as usual through the Strait of Hormuz, it would likely take time for the global economy to normalize after one of the largest oil supply disruptions in decades," said PIMCO economist Tiffany Wilding.
