"Many service sector companies noted that the Middle East conflict had an adverse impact on sales pipelines and general business prospects. Those in the hospitality and transportation sectors typically commented on squeezed discretionary spending and pressure from sharply rising input costs, while professional services firms reported a setback from rising risk aversion among clients.

"New clashes took place overnight as US forces conducted strikes against Qeshm Island while Iran fired missiles and drones towards Kuwait and Bahrain, with the IRGC saying it targeted the US 5th Fleet headquarters in Bahrain. Meanwhile, further Israel-Lebanon talks are expected today, according to the US."
