Selldown linked to disrupted oil supplies, the single biggest contributor to global inflation, which makes most goods and services more expensive

Australian shares plunged on Monday, wiping about $13obn from the value of the ASX midway through the trading session, after a sharp rise in oil prices caused by the Middle East conflict sparked concerns of a breakout in global inflation.

The benchmark S&P/ASX 200 was down 4% in lunchtime trading to dive below the 8,500 point mark, marking the single biggest one-day drop since the announcement of Donald Trump’s “liberation day” tariffs last year.
