A sharp escalation in US-Iran hostilities overnight significantly impacted global financial markets on June 3, 2026, with energy markets and risk sentiment particularly affected. Reports of Iranian ballistic missile strikes on US military installations in Kuwait, followed by further strikes in Bahrain, Saudi Arabia, and Dubai, injected a substantial supply-risk premium into oil markets and rattled investor confidence [1]. As a result, WTI crude oil surged approximately 2.23%, settling near $94.10 per barrel, making it the session's strongest performer [1].
The geopolitical tensions coincided with a wave of stronger-than-expected US economic data. The ADP National Employment Report for May 2026 showed an increase of 122,000 jobs, surpassing the 75,000 forecast and the previous month's 109,000 [1]. The ISM Services PMI for May 2026 also came in robust at 54.5, above the 53.0 forecast and 53.6 previous reading [1]. US Factory Orders for April 2026 rose by 4.8% month-over-month, far exceeding the 2.7% forecast and the prior 1.5% [1]. These data points reinforced expectations that the Federal Reserve may adopt a more hawkish policy stance, leading to higher Treasury yields and a stronger US dollar, while weighing on gold and Bitcoin [1].
Equity markets responded negatively, with the S&P 500 snapping a nine-session winning streak as investors weighed the dual impact of geopolitical risks and the prospect of tighter US monetary policy [1]. Precious metals declined despite the conflict backdrop, and risk sentiment broadly deteriorated [1].
Other notable data releases included a decline in US MBA Mortgage Applications by 2.5% for the week ending May 29, 2026, and a drop in the MBA 30-Year Mortgage Rate to 6.57% from 6.65% [1]. In the Euro area, the S&P Global Services PMI Final for May 2026 was 47.7, below the 50 threshold, while Germany's New Car Registrations for May 2026 showed minimal growth at 0.1% year-over-year [1].
CONCLUSION
The escalation in US-Iran tensions drove a sharp rally in crude oil and heightened market volatility, while robust US economic data fueled expectations of a more hawkish Federal Reserve. Equity markets retreated from record highs, and risk sentiment deteriorated as investors digested the dual impact of geopolitical and monetary policy risks.
