NEW YORK: Wall Street stocks retreated Monday (Jul 20) with early gains fading as the escalating US-Iran conflict lifted oil prices while markets awaited key earnings reports.Iranian President Masoud Pezeshkian described the country as "engaged in a full-scale war" with the United states, while Tehran's Yemeni allies, the Houthi rebels, announced they would blockade Saudi ports, putting at risk Riyadh's ability to bypass the Strait of Hormuz for some of its oil exports.Fresh fighting came after a weekend in which the US announced three new US military fatalities and one service member missing in action.Oil priced pushed higher, with Brent oil futures finishing up 1.3 per cent at US$89.22 per barrel after earlier breaching US$90 a gallon. US gasoline prices jumped back above US$4 a gallon, according to the AAA motor club."The whole US Iran situations is a sounding a little dicey at the moment," said Briefing.com analyst Patrick O'Hare.After last week's losses, semiconductor stocks advanced, but O'Hare said investors remained hesitant about whether tech company earnings will live up to outsized expectations due to artificial intelligence."There is not a lot of conviction right now," O'Hare said. "The question is not so much if giants like Alphabet or Tesla will beat the expectations, but 'Will they beat them by enough?'"Earlier Asian stock markets ended the day mostly lower under the weight of higher oil price, alongside lingering concerns that the AI sector may be overbought.Crude futures have surged over the past week as Washington and Tehran traded fire, raising fears of a sustained disruption in the Strait of Hormuz, through which around one fifth of the world's oil normally passes.

On Monday, markets weighed aggressive rhetoric out of Tehran and Washington against more conciliatory statements that at times moderated the oil market."We have received messages - without going into details - but the main point is that the diplomatic apparatus has been active in recent days and ideas have been conveyed to us by certain mediators," Iranian foreign ministry spokesman Esmaeil Baghaei told a news conference in Tehran.Oil markets were also pressured by uncertainty over Saudi oil supplies.
