This has been causing a lot of debate among central bankers about the best course of action. Some say this burst of inflation is transitory and will pass without any need for any intervention. Others worry that it is the start of a longer period of runaway prices, and argue that we should be raising interest rates and cutting back on “money printing” – also referred to as quantitative easing (QE), which most major economies including the UK have been doing in recent years.
So far, the US Federal Reserve has started tapering its monthly QE at a fairly leisurely rate and there has been talk of rate rises on both sides of the Atlantic, but generally central banks have abstained from getting hawkish so far. But as the inflation numbers have risen and the pressure has increased, there is good reason to fear that they will put their reputations first and succumb. As far as I’m concerned, it would be exactly the wrong move.
The case for the doves
Inflation is like body temperature – it is not a cause but a symptom of underlying potential problems. So before prescribing any policy remedies, you first need to make the correct clinical assessment of what has caused this situation. The recent increase in inflation is not merely due to the central banks stimulating economies with QE and ultra-low interest rates. Had that been the case, inflation would have been going through the roof in the years after the global financial crisis of 2007-09, when these policies were introduced.
It was not until economies reopened after the COVID lockdowns that inflation started to become an issue. There are two things to observe here. First, the situation is not as bad as some inflation fearmongers have been suggesting. In the years since the global financial crisis, it hasn’t been inflation but the risks of deflation that have been keeping central bankers in developed economies awake at night, particularly in Europe and Japan.
There are numerous explanations for this deflationary period, including austerity, lack of public and private investment, low oil prices and globalisation, which helps to keep wages and other costs as low as possible. The chart below shows that inflation in the major economies since 2015 has been consistently below 2%, which is the rate that central banks want to achieve each year for stability.
Inflation around the world since 2015
Even with the recent surge in inflation, the eurozone and Japan’s prices are respectively 3.7% and 9.5% lower what they would have been had they consistently followed an annual 2% inflation path. The UK is now just a little above the target path (by 0.7%), while the US is 3.6% higher – the only significant deviation in the other direction, but hardly catastrophic. One (good) cause of inflation is economic growth, and the US has enjoyed a particularly robust recovery after COVID, with 6% GDP growth expected for 2021. The fact that inflation is rising as a result of this growth is a cost worth every single cent.
Second, the reason for the recent surge in inflation is not excessive monetary stimulus but a revival in global demand outstripping the ability of suppliers to cope (the so-called “disruption and bottleneck” of the supply chain), in conjunction with sharply increasing energy prices.
When supply and demand get back into sync, price rises will stabilise again, since many of the deflationary factors of recent years are still likely to be true in future. This is why the likes of the Bank of England and European Central Bank are forecasting that inflation will ease next year. Even in the US, where inflation is seemingly highest, the expectation is that the recent increase will fade and that prices may even start to fall below the 2% trajectory.
There is therefore no good reason for the central banks to react. A knee-jerk reaction to inflation is also likely to choke off growth which is already set to slow in 2022. It could cause a downturn in financial markets, and pile more debt on to public sector balance sheets by making it more expensive for governments to borrow.
Also, the repercussions would not just be limited to national borders – particularly in the case of the US. By tightening monetary policy, it increases the value of a nation’s currency – and indeed the dollar has already been rising lately against a basket of world currencies. Since the dollar is the global economy’s reserve currency, it is used to price everything from oil to the debts of most developing countries (and their major companies).
If the dollar goes up, oil goes up in price, with huge ramifications for the world economy. Equally, a stronger dollar causes the value of the debts of developing countries to rise, which could destabilise their economies. It could lead to capital flight, in which investors dump government bonds, driving down the value of the local currency and making their debt problems even worse. In short, a strong dollar is too expensive for the global economy to afford.
To stretch my temperature analogy a little further, a surge in global inflation is analogous to the symptoms from Covid vaccines. The global economy is heating up, but this heat is a minor cost of the long-term health of the global economy. A little bit of inflation is necessary to grease the wheels of the economy. As the forces of supply and demand find their post-pandemic equilibrium, inflation will probably ease again like the central bankers have been saying. The best thing for them to do is to hold their ground in the face of temptations and not jump the gun.
