[LONDON] The pound fell after data showing a slowdown in UK core inflation further diminished the prospect of a Bank of England (BOE) interest-rate increase in 2016.
Sterling also dropped to a two-week low against the dollar and sank versus all but two of its 16 major peers before a crucial European Union summit in Brussels where the British government will try to reach a deal altering the terms of its membership.
While the UK's headline inflation rate for January quickened to 0.3 per cent, that's still a fraction of the BOE's two per cent target, suggesting officials won't be able to tighten policy for some time.
"The picture for prices in the UK continues to show that there is no great pressure," said Roberto Mialich, a senior foreign-exchange strategist at UniCredit SpA in Milan.
"Clearly the market would be even more convinced that the Bank of England is in no hurry to start the tightening process," he said.
Investors can expect further volatility in sterling until the uncertainty around the Brexit dissipates, Mr Mialich said.
"Once the whole machine has been kicked off, the market would become very sensitive to polls suggesting who is leading the race, as it happened in the case of the Scottish referendum in the past," he said.
Sterling fell 0.9 per cent to US$1.4306 as of 3:46 pm London time, after sliding to US$1.4277, the lowest since Feb 1. It declined 0.8 per cent to 77.87 pence per euro, its first drop in three days, and approaching the more-than-one-year low reached last week.
Annual growth in core consumer prices, which exclude volatile food and energy prices, slowed to 1.2 per cent from 1.4 per cent in December, while the headline inflation rate was the highest in a year.
"The probability of a leave vote is under-priced in markets," said Mark Dowding, co-head of IG debt at BlueBay Asset Management.
"We are short at the moment and this is a position we would be very happy to add to," he said.
A short position is a bet on a fall in the asset's value. BlueBay manages US$58 billion, according to Dowding, who sees pound going down to US$1.25 if the UK were to leave the common bloc.
