Exceptionally low oil prices have thrown world financial markets a curve ball by driving bond yields sharply lower and undermining share prices.
Major sharemarkets, particularly those with exposure to the energy sector, weakened and bond yields continued their march lower as oil prices under US$50 a barrel added more weight to already considerable deflationary pressures.
On Wall St, the Dow Jones Industrial Average dropped by 1.8 per cent, or 96.5 points, to 5333 after oil prices dropped to five-and-a-half year lows.
Closer to home, Australian stocks - led by declines in energy companies - weakened, with the All Ordinaries Index dropping by 83 points, or 1.53 per cent, at 5346. In Britain and Europe, benchmark share indices dropped by around 2 per cent each on the back of lower oil prices and their likely deflationary effects, coupled with worries about poorer growth prospects in Europe.
The New Zealand sharemarket, which has a relatively light exposure to oil sector stocks, weakened - the NZX 50 dropping by 41 points (0.7 per cent) to 5561.
