Since the war began on February 28, the benchmark has slumped 6.3 per cent, wiping out more than $190 billion in market value. Materials weighed as BHP (ASX:BHP) dropped 2.3 per cent to $49.80 after China widened a ban on its iron ore for the second time in two weeks, though Fortescue (ASX:FMG) gained 4.1 per cent as Macquarie noted it stood to benefit from its rival’s misfortune.

Syrah Resources (ASX:SYR) plunged 29.2 per cent after the US International Trade Commission rejected tariffs on Chinese graphite anode materials. Banks provided support as an expected rate rise on Tuesday would boost net interest margins – NAB (ASX:NAB) rose 1.5 per cent and CBA (ASX:CBA) 1.3 per cent. Energy stocks firmed as oil traded flat around US$101 a barrel, with Yancoal (ASX:YAL) climbing 4.5 per cent to cap a nearly 20 per cent weekly gain as the Middle East conflict buoyed coal prices.

Wall Street whipsaws as Iran war escalates; Brent crude tops US$100, megacaps slide

Volatility gripped Wall Street as the S&P 500 erased a nearly 1 per cent gain to finish lower, with escalating US strikes on Iran pushing Brent crude above US$100 for the first time since the conflict began two weeks ago. A gauge of megacap stocks has now fallen more than 10 per cent from its record. Treasuries rallied initially on soft economic data – consumer spending barely rose in January and consumer sentiment hit a three-month low – before longer-term bonds sold off on inflation fears stoked by surging energy prices. The core PCE inflation gauge matched estimates, while the dollar rose to its highest since December. The Fed is widely expected to hold rates steady next week, with investors focused on any shift in outlook given the war’s impact on both inflation and growth.
