Maybe it’s because I am so adamant that quantitative easing (QE) isn’t going to create inflation that I notice them so much.
But then again, there is a reason these charts pop up time and again. After all, the US Federal Reserve has increased its balance sheet by $2.8 trillion, or 13.6% of US GDP, between January and July 2020. The Bank of England (BOE) has expanded its balance sheet by $306 billion or 10.7% of UK GDP, and the European Central Bank (ECB) by $2.3 trillion, or 19.9% of eurozone GDP, over the same time period.
All this money has to go somewhere and when it arrives in the economy, it will not only create growth, it will also create inflation.
Exorcising the Ghosts of 2009
But unlike in 2009 and 2010, when we were in truly uncharted waters, we now know how QE works. We have had more than a decade to study its effects on economic growth and inflation.
A group of researchers recently examined all the studies done on the impact of QE on growth and inflation over the years. In the United States, they found that QE to the tune of 1% of US GDP increases the price level by 0.21%. In the United Kingdom, the price level rises by 0.04%, and in the eurozone by 0.11%.
If we apply these findings to the balance sheet expansion of central banks thus far in 2020, we come to an expected increase in the price level of 2.9% in the United States, 0.4% in the United Kingdom, and 2.2% in the eurozone.
Central Bank Balance Sheet Expansion 2020: Cumulative Impact on Price Levels
Keep in mind that this is an increase in the price level, not an increase in inflation. What these numbers mean is that if the total effect of QE were to be felt over one year, inflation rates in the United States would go up by 2.9 percentage points in that year and then go back to the previous level, assuming there is no additional QE.
If the effect of QE is spread out equally over two years, then inflation rates in Year 1 and Year 2 would be 1.45 percentage points higher and then fall back to pre-QE levels thereafter, and so on.
So what’s the takeaway from all of this?
The overall impact of the balance sheet expansion by central banks in 2020 will be very small at best. For inflation to really get out of hand, we need much more balance sheet expansion than we had in the financial crisis and during the COVID-19 pandemic. And not just once or twice, but every year for the foreseeable future.
So there’s no need to be afraid of central bank balance sheets or those scary charts. Jerome Powell, Andrew Bailey, and Christine Lagarde shouldn’t keep us up at night. They are harmless.
