Inflation is defined as the general progressive increase in prices of goods and services over time in an economy. When the general price level rises, each unit of currency buys fewer goods and services, thus, inflation corresponds to a reduction in the purchasing power of money. Fiat currencies now function as a gauge of consumer confidence in the government that backs it.
Brazil in the past and more recently Zimbabwe, experienced hyperinflation – where prices of goods and services rose uncontrollably over a defined time period; Zimbabwe recorded the second highest incidence of hyperinflation in history at an approximate 98% daily inflation rate! The cause of this was due to numerous economic shocks and the government’s response was to print more money to help stimulate growth. Amidst political corruption and significant declines in economic output and exports, hyperinflation spun out of control.
These countries are not the only to have experienced the effect of money printing and inflation; in fact, the reason why MMT is a current topic is because of many countries’ responses to the economic whiplash caused by the 2020 Coronavirus pandemic. These include the fiscal policies put in place by the UK and US governments – which are being argued as the reason for the inflation woes being experienced in both countries right now.
In the UK, the Bank of England printed around £500 billion during the pandemic, and called it ‘quantitative easing.’ In May 2022, former governor of the Bank of England, Lord Mervyn King, stated, “Governments stepped in and put in a lot of money for furlough schemes or raising unemployment benefits. That was very sensible… The problem was that central banks also printed a great deal of money and that wasn’t needed…it put a lot of money into the system.”
In economics, the classical theory of inflation links a sustained price inflation to an excessive increase in the amount of money in circulation, aka the more money you suddenly put into the system, the higher inflation will rise. In the US, the Federal Reserve printed US$4.8 trillion during the pandemic for their stimulus packages and they are now being targeted as to being a major contributor to the inflation woes being experienced across the US now.
Interest rates become largely irrelevant under MMT as the supply of money would outweigh the value of money. Imagine you are the owner of the sole avocado tree, which bears only once a year. The economic value and return of owing the tree increase over time since it is a rare commodity and who wouldn’t want your avocados!? If every local farmer started planting avocado trees, the market in time, will become over-supplied and the rarity and value of avocados would decrease – supply outweighs demand.
Governments may issue Bonds, Treasuries and Taxes, under MMT, to function as Contractionary or Expansionary Monetary Policy tools to control the supply of money in the economy, as they can print money as needed or withdraw money to sterilize and reduce the money in circulation.
However, persuading investors to find value in an economy where there is no true demand for their products bears no long-term benefit.
The amount of money a government can create is limited by the spare productivity capacity of the economy. Otherwise, the amount of goods in production remains the same and is only met by inflation to balance supply and demand.
