US stock markets surged on Wednesday while oil prices plunged sharply as investors bet on a possible breakthrough in US-Iran negotiations that could reopen the Strait of Hormuz and restore global crude supplies, AP reported.The S&P 500 climbed 0.8 per cent and headed towards another record close. The Dow Jones Industrial Average rose 487 points, or 1 per cent, while the Nasdaq Composite gained 0.8 per cent.Brent crude, the international oil benchmark, slumped 5.7 per cent to $103.61 per barrel after falling from levels above $115 earlier this week. At one point during the session, Brent briefly dropped below $97 before recovering some losses.The rally came after US President Donald Trump said the Strait of Hormuz could be “OPEN TO ALL” if Iran accepts a reported agreement, though he did not disclose details of the proposed deal.The Strait of Hormuz has remained at the centre of the global energy crisis since the Iran conflict disrupted oil tanker movement through the Persian Gulf, pushing crude prices sharply higher and stoking inflation fears worldwide.Markets also drew optimism from Trump’s indication that the US may scale back efforts to reopen the strait through military means, while China called for a comprehensive ceasefire after talks between Chinese and Iranian foreign ministers.Asian and European markets also rallied strongly. South Korea’s Kospi surged 6.5 per cent to cross the 7,000 mark for the first time, while Hong Kong’s Hang Seng rose 1.2 per cent. London’s FTSE 100 gained 2.2 per cent and France’s CAC 40 climbed 2.9 per cent.On Wall Street, technology and AI-linked stocks led gains after strong earnings reports.AMD jumped 19.3 per cent after reporting better-than-expected quarterly profit and revenue.

United Airlines climbed 5.2 per cent, while Carnival and Royal Caribbean gained 5.5 per cent and 5.2 per cent, respectively.In the bond market, Treasury yields fell as easing oil prices reduced inflation concerns. The yield on the 10-year Treasury dropped to 4.35 per cent from 4.43 per cent a day earlier.Lower bond yields generally reduce borrowing costs for households and businesses and tend to support equity valuations.
