Inflation in the Euro Area has risen sharply of late, with the flash estimate for February at 2%, from 0.6% in November, and is now at the highest rate in four years. Consumer prices have also picked up momemtum in the other major economies: In the UK the inflation rate has accelerated from 0.9% to 1.8% in four months while in the US the increase is from 1.6% to 2.5% over the same period. As a consequence markets have shifted away from the fear of deflation and now the issue is whether this upturn in prices will prove short-lived or is it the beginning of a more sustained period of inflation, ultimately requiring a faster policy response than currently priced in to markets. That change is clearest in the US, with the Fed now expected to raise rates again this month.
The more benign interpretation of the inflation trend is supported by measures of core inflation, which exclude volatile components like Food and Energy. On that definition, the euro inflation rate is at 0.9%, unchanged over the last three months, and so the rise in inflation is due to a rebound in energy prices ( up an annual 9.2% in February) and unprocessed food ( plus 5.2%). These changes partly reflect base effects ( large monthly falls a year ago now dropping out of the annual figure) and the recent increase in global commodity prices, notably crude oil. In the US the Fed’s preferred measure of inflation is the core consumption price deflator, and that is rising at an annual rate of 1.7%, or at an annualised rate of 1.6% over the past three months, again not flashing red.
What determines core inflation? Profit margins have an impact ( can firms pass on higher import prices in the UK for example) but the main factor is labour costs, and in most countries wage growth remains subdued and is much lower relative to unemployment than in the past. Why this is the case is the subject of much debate but in the absence of a pronounced pick up in wage inflation it is difficult to see price inflation accelerating for a prolonged period.
Headline inflation is what matters to consumers, of course, and the recent rise will dampen real incomes and probably reduce real consumption and hence GDP growth. A 2% inflation rate is therefore worse for the economy than a 1% rate, yet Central Bankers have argued the opposite, as most use a 2% inflation figure as their definition of stable prices. How this became conventional wisdom is hard to fathom ( prices rise by 22% in a decade and just shy of 50% in 20 years, hardly a good measure of stability) while the fear of deflation is strong, even though Japan, the land of falling prices, has not really suffered in terms of its real GDP growth per head. Inflation at 2% may be fine with wage growth of 4%, as was the case , but not if wage growth is 2% or below, as appears to be the ‘new normal’. There is not much central bankers can do in the short term to influence energy or food prices, of course, but higher headline inflation will dampen real spending in the absence of an acceleration in nominal wage growth.
