LONDON ( Project Syndicate )— Amid all the talk of when and how to end or reverse quantitative easing (QE), one question is almost never discussed: Why have central banks’ massive doses of bond purchases in Europe and the United States since 2009 had so little effect on the general price level?

Catch up on the latest on inflation here.

Between 2009 and 2019, the Bank of England  injected £425 billion  ($588 billion)—about 22.5% of the United Kingdom’s 2012 gross domestic product—into the U.K. economy. This was aimed at pushing up inflation to the BOE’s mandated medium-term target of 2%, from a low of just  1.1% in 2009 . But after 10 years of QE, inflation was below its 2009 level, despite the fact that house and stock market prices were booming, and GDP growth had not recovered to its precrisis trend rate.

Since the start of the COVID-19 pandemic in March 2020, the BOE has bought an additional £450 billion worth of U.K. government bonds, bringing the total to £875 billion, or 40% of current GDP. The effects on inflation and output of this second round of QE are yet to be felt, but asset prices have again increased markedly.

Not much trickles to the real economy

A plausible generalization is that increasing the quantity of money through QE gives a big temporary boost to the prices of housing and financial securities, thus greatly benefiting the holders of these assets. A small proportion of this increased wealth trickles through to the real economy, but most of it simply circulates within the financial system.

The standard Keynesian argument, derived from John Maynard Keynes’s  General Theory,  is that any economic collapse, whatever its cause, leads to a large increase in cash hoarding. Money flows into reserves, and saving goes up, while spending goes down. This is why Keynes argued that economic stimulus following a collapse should be carried out by fiscal rather than monetary policy. Government has to be the “spender of last resort” to ensure that new money is used on production instead of being hoarded.

But in his  Treatise on Money , Keynes provided a more realistic account based on the “speculative demand for money.” During a sharp economic downturn, he argued, money is not necessarily hoarded, but flows from “industrial” to “financial” circulation. Money in industrial circulation supports the normal processes of producing output, but in financial circulation it is used for “the business of holding and exchanging existing titles to wealth, including stock exchange /zigman2/quotes/210599714/realtime SPX -0.84% and money market /zigman2/quotes/211347041/realtime BX:TMUBMUSD01M +18.75% transactions.” A depression is marked by a transfer of money from industrial to financial circulation—from investment to speculation

So, the reason why QE has had hardly any effect on the general price level may be that a large part of the new money has fueled asset speculation, thus creating financial bubbles, while prices and output as a whole remained stable.

State-created financial instability

One implication of this is that QE generates its own boom-and-bust cycles. Unlike orthodox Keynesians, who believed that crises were brought on by some external shock, the economist Hyman Minsky thought that the economic system could generate shocks through its own internal dynamics.

Bank lending, Minsky argued, goes through three degenerative stages, which he dubbed hedge, speculation, and Ponzi. At first, the borrower’s income needs to be sufficient to repay both the principal and interest on a loan. Then, it needs to be high enough to meet only the interest payments. And in the final stage, finance simply becomes a gamble that asset prices will rise enough to cover the lending. When the inevitable reversal of asset prices produces a crash, the increase in paper wealth vanishes, dragging down the real economy in its wake.

Minsky would thus view QE as an example of state-created financial instability. Today, there are already clear signs of mortgage-market excesses. U.K. house prices  increased by 10.2%  in the year to March 2021, the highest rate of growth since August 2007, while indexes of overvaluation in the U.S. housing market are “ flashing bright red .”

And an econometric study (so far unpublished) by Sandhya Krishnan of the Desai Academy of Economics in Mumbai shows no relationship between asset prices and goods prices in the U.K. and the U.S. between 2000 and 2016.

A drug that cures the illness it causes

So, it is hardly surprising that, in its February 2021 forecast, the BOE’s Monetary Policy Committee estimated that there was a  one-third chance  of U.K. inflation falling below 0% or rising above 4% in the next few years. This relatively wide range partly reflects uncertainty about the future course of the pandemic, but also a more basic uncertainty about the effects of QE itself.
