Financial markets rallied sharply on Tuesday as renewed diplomatic efforts to resolve the Middle East conflict sent stock indices soaring and crude oil prices tumbling.
Wall Street's benchmark S&P 500 and technology-heavy Nasdaq both surged, returning to levels not seen since before the United States and Israel initiated military action against Iran in late February. The dramatic shift followed progress in U.S.-mediated negotiations between Israel and Lebanon, with Washington pushing for a cessation of hostilities between Israel and Hezbollah.
Analyst David Morrison of Trade Nation noted that investors are "pricing in victory," with many believing the conflict's resolution could be measured in days or weeks rather than years. "Nobody wants to be under-exposed to risk assets should the war suddenly conclude, or even if the Strait of Hormuz was unblocked," Morrison observed.
However, not all market watchers share this optimism. Tom Cahill, chief investment officer at Ventura Wealth Management, cautioned that markets might be "overreacting" to the diplomatic developments. "There are still a lot of question marks as to whether a true agreement is to be had between the United States and Iran," Cahill warned, expressing concern that companies could soon cite the ongoing conflict as justification for lowering earnings forecasts.
The potential peace breakthrough triggered a significant retreat in oil prices, which had recently approached $100 per barrel. This decline weighed particularly on European energy giants BP and Shell, limiting gains in London's equity market to just 0.3% despite broader regional advances.
"Demand destruction will spread as scarcity and higher prices persist," the International Energy Agency warned in its latest monthly report, noting that second-quarter crude demand could experience its sharpest decline since the pandemic-induced economic collapse of 2020.
Asian markets closed with substantial gains, while the U.S. dollar—traditionally viewed as a safe-haven asset during geopolitical turmoil—weakened against major currencies. The financial sector showed mixed performance, with Citigroup shares advancing despite broader banking sector uncertainty, while French luxury conglomerate LVMH reported a 6% sales decline for the first quarter, attributing the drop to ongoing conflict-related disruptions.
