World financial markets were unsettled again on Thursday as a week-long sell-off in benchmark government bonds, stocks and the dollar, and a race up in oil prices, was compounded by UK election uncertainty. London’s FTSE (.FTSE), the region’s biggest share market, meanwhile, was down 0.6 percent and sterling (GBP=D4) was a fraction lower at $1.5234 as attention turned to the day’s national election which remains too close to call.
