(ShareCast News) - Stocks in London finished higher as the pound slid back against the dollar after data showed consumer prices unexpectedly dropped in October.The FTSE 100 was up 0.59% to 6,792.74, while the pound was down 0.8% against the greenback at 1.2402 after data from the Office for National Statistics showed the consumer prices index fell to 0.9% in October from 1% in September, below economists' expectations for a nudge up to 1.1%.The ONS said a large jump in input prices was not yet being reflected on the high street.Month-on-month, CPI rose 0.1% versus the previous month's 0.2% increase and the consensus forecast for an acceleration to 0.3%.Core UK CPI, which strips out more volatile prices like food and fuel, rose 1.2%, which was again short of the 1.4% consensus estimate and down from the prior month's 1.5% rise.The ONS said the main downward pressures on the CPI rate were prices for clothing and university tuition fees, which rose by less than they did a year ago, along with falling prices for certain games and toys, overnight hotel stays and non-alcoholic beverages.Spreadex's Connor Campbell said: "Coming in at 0.9%, the markets were shocked that the CPI reading not only failed to hit the 1.1% forecast, but actually arrived under the 1.0% seen in September. And while analysts were quick to state that prices are still set to rise, and rise quite sharply, the news of this inflation respite was taken as a big blow by sterling, as it makes it even more unlikely that the Bank of England will consider lifting interest rates away from their record lows any time soon."Cable finished the session down by 0.61% at 1.2419."Despite October's weak number, CPI inflation remains set to make big strides towards the 2% target over the next three months, as the anniversary of sharp falls in motor fuel and food prices is reached. [...] As a result, we still expect CPI inflation to peak at about 3.5% by the end of 2017, crippling consumers and preventing the MPC from announcing more stimulus," said Samuel Tombs, chief UK economist at Pantheon Macroeconomics.Tombs expected CPI to peak at roughly 3.5% by the end of 2017, while Barclays Research expected it to average 2.4% next year.Crude oil futures stormed back following three back-to-back sessions of losses, amid hopes that OPEC will agree a production cut at its meeting later this month.
