UK inflation set to tumble below target by autumn

• ? We expect CPI inflation to slow markedly this year, dropping below the 2% target by the autumn. The inflationary impulse from the 2016 depreciation is fading and should partially reverse, while global food and energy prices are expected to stabilise. Base effects will become increasingly important.
• ? CPI inflation reached a five‐and‐a‐half‐year high of 3.1% in November, up from a little over 1% a year earlier. The 2017 pick‐up in inflation was the result of a perfect storm of a weaker pound, higher oil prices and sharp rises in domestic electricity bills. But inflation has subsequently slowed, reaching 2.5% in March. And, after a brief hiatus, we expect the downward trend to continue as we move through the year.
• ? The key driver of lower inflation will be weaker core pressures. In line with the literature, there is already evidence that the impact of sterling's depreciation is fading, and we think that the pressures could partially reverse if sterling continues to strengthen. We see little prospect of an offsetting escalation in domestic cost pressures. The recent pick‐up in wage growth has been muted and a further acceleration above 3% looks unlikely while there remains slack in the labour market.
• ? The food, petrol and energy categories contributed 0.8 ppt to CPI inflation last year, compared with a drag of 0.5 ppt in 2016, as stronger global pressures combined with the weaker pound. But as global prices have been more subdued of late, by the end of 2018, we expect these categories to be contributing 0.5 ppt to CPI inflation.
• ? The final element behind the expected slowdown in inflation is base effects. The comparison with last year's strong price pressures will depress the 2018 inflation rate, and we see the base effects being at their strongest mid‐year.
• ? We think it unlikely that such a slowdown in inflation would derail the MPC from hiking interest rates twice this year. But it could temper its hawkishness in 2019.
