The ongoing war in the Middle East continued to behave as an overhang on investor sentiment on Wednesday, with the U.S. and Iran exchanging fire.

U.S. Central Command reported that American units neutralized drones and ballistic missiles launched by Iran, subsequently executing "self-defense strikes" on Qeshm Island. These actions followed an announcement from the Kuwaiti military via social media late Tuesday, which confirmed that their air defense networks were actively engaged in "intercepting hostile targets."

This was among the most serious flare-ups since the ceasefire negotiations began in April. 

“Ongoing tensions in the Middle East continued to cloud the broader risk backdrop,” said Fawad Razaqzada at Forex.com in an interview with Bloomberg News. “Fresh exchanges between US and Iranian forces overnight raised questions about the durability of the ceasefire arrangement.” 

Alternatively, the Federal Reserve on Wednesday reported that the U.S. economy expanded at a slight-to-moderate pace through May, even as escalating geopolitical tensions in the Middle East drove up energy costs and fueled a sharp acceleration in inflation.

According to the latest Beige Book survey of regional economic conditions, business activity increased across 10 of the central bank's 12 districts. However, soaring costs due to spiking oil prices amid the war in the Middle East is reshaping consumer behavior and threatening corporate profit margins.
