Equity futures across major US indices posted gains Tuesday morning as market participants remained focused on diplomatic developments between Washington and Tehran, despite recent military confrontations in critical Middle Eastern waterways.
Contracts tracking the Dow Jones Industrial Average advanced 233 points, representing a 0.5% increase. Futures linked to the S&P 500 climbed 0.6%, while Nasdaq 100 contracts surged 0.9%. Traditional trading was suspended Monday in observance of Memorial Day.

In a social media post on Truth Social Monday evening, President Trump stated that diplomatic discussions with Iranian leadership were “proceeding nicely.” He simultaneously emphasized that additional military operations remained under consideration should negotiations collapse.
Despite ongoing tensions, market participants showed resilience following news of the most recent military engagement. US Naval forces neutralized two Islamic Revolutionary Guard Corps vessels that were reportedly deploying explosive devices in the strategically vital Strait of Hormuz. Pentagon officials characterized the response as defensive in nature.
Iranian military leadership issued statements maintaining their prerogative to respond to what they termed violations of cease-fire protocols.
Crude Oil Markets Tumble on Diplomatic Progress
Oil markets exhibited immediate reaction to the diplomatic momentum. West Texas Intermediate crude contracts plummeted approximately 4% to reach $92.84 per barrel. International benchmark Brent crude similarly declined more than 4%.
Domestic crude prices recorded an 8.4% weekly decline, marking the most substantial weekly contraction since mid-April. The reduction in energy costs has emerged as a significant catalyst supporting recent equity market strength.
The benchmark 10-year Treasury note yield declined 6 basis points to 4.51%. The US dollar index weakened 0.2% against major global currencies.
All three primary equity benchmarks achieved positive weekly performance, with the S&P 500 extending its longest consecutive weekly advance since December 2023.
Investment Strategists Flag Seasonal Volatility Risks
Market sentiment remains divided. Dennis Follmer, chief investment officer at Montis Financial, characterized the Middle Eastern situation as “a long stalemate with nearly all the ships still stranded in the Persian Gulf.”
Follmer noted that the S&P 500 continues to benefit from momentum generated by robust first-quarter corporate earnings results, but cautioned that “the likelihood of a summer selloff is high” given the conclusion of quarterly reporting season.
Market participants are recalibrating Federal Reserve policy expectations. The implied probability of a July interest rate increase has jumped to 8.5%, a dramatic rise from merely 0.9% one month earlier, based on CME Group’s FedWatch tool data.
Bitcoin retreated 1.1% to $76,679 during the past 24-hour trading period. The digital asset typically moves in tandem with broader risk appetite indicators.
Financial markets demonstrated notable stability in response to the latest US-Iran military exchange, with futures contracts maintaining upward momentum even following reports of the Strait of Hormuz incident. The sustainability of this composure will likely hinge on the trajectory of diplomatic negotiations in coming sessions.
