I just finished showing that this is wrong. The Fed buys government assets (bonds), makes an entry into their balance sheet, and transfers the money to the federal government. Money is created. Not literally printed, but an electronic transfer. The government then spends money that did not exist before they issued the bonds.
When a government is borrowing 2 trillion per year, where do you think the money is coming from? The U.S.'s biggest foreign bond holder, Japan, holds about 1.1 trillion in US securities. China’s around $800 billion. That’s cumulative, not what they buy per year.
What happens in a bond auction is that the government offers a bond at a certain interest rate. If there are no buyers, the yield has to increasse until the bond is attractive enough to sell. So if the fed doesn’t want to lose control of interest rates, it will buy the bonds if there are no other takers. This means the fed is buying the bonds that no one else wants at that price, and the taxpayers take the risk. And since the Fed doesn’t have its own money to spend, when it buys bonds it basically makes an accounting entry and then releases the money to the seller. When the bond matures, the fed pays back the money it owes with another electronic entry, or it rolls the bond over.
Between 2020 and 2022, the Fed’s balance sheet grew from 2.1 trillion to 5.8 trillion. The money supply grew by about 6 trillion over the same period.
The covid response was almost tailor-made to create inflation. First the government locked everyone down, shrinking supply, then they gave them printed money to pay their bills. We increassed demand while cratering supply, and ballooned the money supply to get away with it. We will be oaying the price for that for years.
This isn’t Democrat vs Republican. Trump did it, Biden did it, countries around the world of varying ideology did it. It was a global concensus, and it was wrong.
