Many countries are reporting their highest rates of inflation in decades: 6.2% in the United States, 4.2% in the United Kingdom, 5.2% in Germany, and above 4% in the eurozone. Some insist that it is a temporary phenomenon; others fear that we must brace ourselves for an extended period of significant price increases driven by expansionary monetary policies and rising public debts.
Still, both camps agree that at least some of the factors behind the recent inflationary surge will soon subside or disappear. In 2020, prices rose only slightly, and even declined in some cases, setting a low baseline for the year-on-year increase in 2021. Surging prices for heating oil, gas, petrol, and diesel are also generally considered to be temporary.
A significant decline in headline inflation can thus be expected in most countries in 2022. In the longer term, however, we must adapt to higher fossil-fuel prices in order to fight climate change. Similarly, though the across-the-board price spikes in building materials, computer chips, and raw materials are not expected to continue indefinitely, nor are we likely to find lasting relief.
After all, the problem is global. When China fully entered world markets in the 1990s, the resulting flood of cheap goods placed downward pressure not only on prices but also on wages. Trade unions, concerned about job losses, were reluctant to demand higher wages.
But now, these pressures are easing. It would be a mistake to think that globalization has ended, but the fact is that international economic integration has slowed, owing to the COVID-19 crisis, the Trump administration’s protectionism, and the decline in the Chinese labor supply as its population ages. As a result, the global economy is more likely to exert more sustained inflationary pressure than in the past. The argument that today’s inflation is only temporary assumes that global unemployment remains substantial, and that trade unions are weak. In that case, there would be no reason to expect that wages will increase significantly, leading to a sustained rise in prices.
But that may not be the case, because the global economy is at a turning point: conditions may be shifting from deflationary to more inflationary overall. At the national level, wages are being driven up by labor shortages in many sectors.
The scarcity of truck drivers in the UK, for example, has translated into considerably higher wage offers. Of course, the economic slump caused by the pandemic was not comparable to a normal downturn, so it remains to be seen how long it will take for these sectoral wage increases to spread throughout the economy.
In any case, it is monetary policy that determines the course of inflation. In the short term, central banks can do nothing to prevent a price surge caused by factors such as rising energy costs, nor should they try to do so. What matters is that citizens and financial markets do not lose confidence in central banks’ determination to stabilize inflation (typically at around 2%) over the medium term.
So far, the flooding of financial markets with liquidity – notably through massive bond purchases – has played a major role in driving up asset prices. The danger now is that this price inflation, combined with a large expansion of the money supply, will spread to consumer prices, which are also affected by the sharp rise in public debt.
The US Federal Reserve and the European Central Bank (ECB) consistently assume that today’s inflationary expectations are firmly anchored at the target level of 2%, and most published inflation expectations for the US and the eurozone appear to confirm this view. But these central banks’ own massive bond purchases are distorting market expectations. Copyright: Project Syndicate, 2021
