US share markets live updates: S&P 500, Nasdaq futures turn positive; Dow pares losses

US President Donald Trump on Tuesday announced that the United States will provide risk insurance for maritime trade moving through the Persian Gulf, in an attempt to restore tanker movement through the strategically critical Strait of Hormuz. Tanker traffic through the strait, regarded as the world’s most vital crude oil transit route, had effectively halted after a commander of the Islamic Revolutionary Guard Corps warned that ships attempting to pass through the corridor could be set on fire. The US move is aimed at reassuring shipping companies and oil traders amid escalating tensions in the region and preventing prolonged disruption to global energy supply chains.

US stocks endured another volatile session on Tuesday as fears of a prolonged US–Iran conflict weighed heavily on investor sentiment, though later remarks from President Donald Trump helped pare some of the steepest losses.
