Australia’s share market has wiped the previous session’s gains with interest after US bond yields surged, as global borrowing costs and high oil prices continue to sap investor confidence.
The S&P/ASX200 dropped 132.4 points by midday, down 1.51 per cent, to 8,656.6, as the broader All Ordinaries tumbled 132.6 points, or 1.48 per cent, to 8,836.6.
