On June 1, 2026, global financial markets experienced significant volatility driven by geopolitical developments and robust US economic data. The session began with a sharp risk-off move after Iran suspended nuclear negotiations in protest over Israeli strikes in Lebanon, which led to a steep decline in US equities at the open. However, sentiment reversed after President Trump announced an Israel-Hezbollah ceasefire and stated that Iranian negotiations were progressing rapidly, prompting a recovery in equities toward all-time highs [1].
Oil markets reacted strongly to the geopolitical tensions, with WTI crude oil surging approximately 5% to close near $90.90 per barrel amid fears of supply disruptions in the Strait of Hormuz [1]. In contrast, gold and Bitcoin retreated as safe-haven demand diminished and expectations for Federal Reserve rate hikes increased following the release of a stronger-than-expected ISM Manufacturing PMI [1].
The US ISM Manufacturing PMI for May 2026 came in at 54.0, surpassing both the forecast of 53.0 and the previous reading of 52.7, reinforcing the hawkish outlook for Federal Reserve policy [1]. Other notable economic data included a China NBS Manufacturing PMI of 50.0, a Euro area S&P Global Manufacturing PMI of 51.6, and a Swiss procure.ch Manufacturing PMI of 57.3, all indicating varying degrees of expansion in global manufacturing activity [1].
Market participants closely monitored the interplay between geopolitical risks and economic data, with the rapid shifts in sentiment highlighting the sensitivity of asset prices to both headlines and fundamentals. The strong ISM print and oil price spike were seen as key drivers of the day's market action [1].
CONCLUSION
The session underscored the market's vulnerability to geopolitical developments, with oil and equities reacting sharply to news from the Middle East and US economic data. While risk assets recovered on ceasefire news and strong US manufacturing data, the elevated volatility signals ongoing uncertainty for investors.
