Over the past two years, as the Federal Reserve fought to rescue the economy from the clutches of the coronavirus, the central bank's emergency remedies increased the nation's money supply by an astonishing 40 percent That was almost four times as much new money as had been created during the two years that preceded the pandemic. To some Fed critics, [that] explains why the United States is experiencing its highest inflation since 1982. All that money chasing after limited supplies of goods such as cars, computers and furniture is inevitably bidding up prices, they say. The Fed agreed with that view the last time the United States had a serious inflation problem. In 1979, then-Fed Chair Paul Volcker clapped a lid on the money supply and drove inflation from a peak of 14.8 percent to 2.5 percent three years later, at the cost of two punishing recessions. But the current Fed chair, Jerome H. Powell, has dismissed claims that the Fed's money-printing is fueling today's price spiral. Like his most recent predecessors, dating to Alan Greenspan, Powell says that financial innovations mean there no longer is a link between the amount of money circulating in the economy and rising prices. The Fed's broadest measure of the money supply, called M2, is more than $21.6 trillion today, up from $15.5 trillion in February 2020.
