Will transitory inflation start to be worryingly persistent soon?
All the talk now is about inflation and its impact on interest rates and the economy. We look at whether investors should be worried. Inflation is perhaps the most crucial metric in economics, and as we hit the halfway point in 2021 it is concerning investors and economists in a way not seen before. The pandemic and related lockdowns in the US, UK and around the world had a profound effect on economies and we are yet to fully understand all the implications. The last time the world saw a pandemic that was remotely comparable was the 1918 Spanish flu. Even that does not necessarily give us much to go on because the world and its economy were completely different then, and there were no lockdowns of the kind we have seen recently. The talk coming out of the Bank of England, Federal Reserve and other central banks is of transitory inflation. That is to say; a relatively short period of price rises caused by a spike in demand as lockdowns end. Something can only be considered transitory for so long though, and it is a very ill-defined concept. Energy prices are a key driver of inflation in many scenarios, but particularly when the global economy is quickly moving from much reduced travel and transportation of goods back to more normal levels. Industrial activity is also firing back up and sucking in significantly more power. Departing Bank of England chief economist Andy Haldane has struck a very cautionary tone recently. He warned the economy is surfing as high a wave as any in its history and said he expects inflation to be near 4% by the end of the year, which is double the Bank of Englands target. Other economists such as Sanjay Raja of Deutsche Bank are already warning that inflation is getting ahead of expectations. It's clear that coming into 2021 we underestimated the strength and persistence of inflationary pressures, he said. Where we previously saw headline CPI [consumer price inflation] peaking at 2.2% year on year with risks fairly balanced, our updated forecasts have CPI peaking at 3.2%. with risks tilted still to the upside. For RPI, we see the annual rate peaking closer to 4.5% year on year.  Beyond 2021, we expect a little bit of persistence remaining in the inflation data owing to a few structural factors that should, on balance, be more inflationary for the UK outlook.  As a result, Deutsche pushes up its inflation forecast for 2022 and 2023 CPI to 2.3% and 2% year-on-year (annual average), respectively, from 1.7% and 1.9% at the start of the year. As well as energy, Raja points to the service sector as a major factor. Concentrated price rises in services, particularly within catering, personal and leisure services as wage pressures in those industries have picked up by more than we previously anticipated, he noted. Raja does not see a quick end to the inflationary pressure, in contrast to proponents of the transitory theory. If anything, he sees inflation rising further from here. Risks are skewed to a stronger rebound in prices. Stronger pass-through of input price pressures, longer and tighter bottlenecks, and entrenched pay rises are three key risks to our inflation outlook. Indeed, survey data, thus far, is consistent with inflation peaking closer to 4% year on year. Should these risks crystalise, the expected unwind in price pressures will likely take longer, leaving headline CPI above target until perhaps the end of next year.
