Market Meltdown: Worst Day For Aussie Stocks Since GFC

The Australian stock market has shed nearly six percent - or about $120 billion - as ongoing coronavirus panic and an oil price plunge hands the bourse its worst open since the global financial crisis. 

The benchmark S&P/ASX200 dropped 339.8 points, or 5.47 percent, to 5,876.4 by midday on Monday, while the broader All Ordinaries index was 350 points, or 5.57 percent, lower at 5,937.5.

Both major indexes had earlier hit their lowest levels since February last year, shedding as much as 5.7 percent during the morning as Monday's losses wiped $120 billion from the market.

More than $440 billion has been lost from peak-to-trough since the bourse hit an all-time high of 7289.7 points on February 20 - just three weeks ago.

Losses over that period are close to 20 percent, which represents the threshold of a so-called bear market.

If a 5.5 percent loss is sustained through to the close of trade, it would be the worst day for the ASX/200 since October 16, 2008, when the world was in the throes of the GFC.

The energy sector endured its biggest ever intraday percentage slump, falling by as much as 19 percent, after Saudi Arabia slashed its oil prices in a bid to gain market share from Russia.

Goldman Sachs warned that the price of Brent crude could hit as low as $US20 a barrel.
