(Drivebycuriosity) - America´s political landscape has changed again. The enemies of the new President claim that he will bring inflation back. But during Trump´s first regency there was no inflation, it happened under Biden (chart above economics).
We learned from Milton Friedman that “Inflation is always and everywhere a monetary phenomenon” and inflation happens "when too much money chases too few goods". The causal relationship between money supply and inflation was already recognized by Nicolaus Copernicus.
The astronomer explained in the year 1517 why "too much money"
causes inflation. Copernicus` "quantity theory of money" is based on
observations: Early in the 16th century Spain conquered today`s Latin America and
looted the silver stocks. The Spaniards send the precious metal to Europe where
is was printed into coins and used as money.
As a result the European money supply jumped, meeting a restrained supply of goods & services. The flood of money raised suddenly the demand for scarce goods & services and caused a jump of the price level.
Elaborated studies by Milton Friedman, Karl Brunner, Allan Meltzer and many other economists (known as Monetarists) described already in the 1960s how and why the inflation rate follows the growth rate of money with a time lag (causal connection).
Helicopter Money
The recent inflation was caused by a deluge of money. In 2020 & 2021 the Biden government flooded the economy with stimulus checks in the value of trillions of dollars to fight the Covid19 recession (American Rescue Plan). The government checks got financed by massive bond purchases by the Federal Reserve (Quantitative Easing known as QE1,QE2 & QE3).
The government money landed directly on the bank accounts of the Americans, blowing up the money volume M2 (bank notes & coins & deposits at banks). Milton Friedman described this as helicopter money (cato ). As a result in 2021 & 2022 the US money supply M2, the engine of the inflation, jumped 40% (chart below). The money deluge met a constrained supply of goods & services partly - partly because of Covid19.

Fortunately
the money flood ended already in 2022 and the money supply shrank for a while.
Since October 2023 the money volume is growing again, but only
moderately. Since
inflation follows the growth of money, the inflation rate (growth rate
of prices) will follow the pull of the slowly growing money supply and the
inflation rate will stay low.
The Trump inflation claim is based on economic illiteracy and ignorance of history.
