Money Creation in the Modern Economy

by | Last updated Oct 11, 2019 | Economy, Markets, and Interest Rates

Money creation in the modern economy involves mostly private commercial banks and little to do with the U.S. government.

The political season is upon us. And with Thanksgiving just around the corner, complete with turkey, stuffing and football, you might find yourself in the middle of a heated family debate about politics and money.

One family member who is an Ayn Rand fan and watches Fox News faithfully might start crowing about how the government is printing all this money and sinking us into this big hole. He might end up arguing with another family member who happens to be a fan of New York Times columnist and Nobel Prize in Economics laureate Paul Krugman.

Krugman has been adamant since the financial crisis started that the government should be spending more money. This view stems, in part, from a belief that the government, not commercial banks, can boost the amount of cash in the economy.

He is not alone. Many people view money and banking similarly to how the field is idyllically portrayed in the movie It’s a Wonderful Life, in which Jimmy Stewart’s S&L takes in deposits and lends them out to individuals in the community.

In the real world, the opposite happens. Banks create money when they make loans. That is why lending is called credit creation. In fact, what separates capitalism from other economic systems is that private debts created by banks circulate as new money.

For example, say a person who owns a home takes out a $50,000 equity loan. Here a bank is creating a deposit of $50,000 and crediting that person with a loan for the same amount. The customer then spends the money, and a private agreement between the bank and the customer results in new money entering the economy

The Bank of England, the U.K.’s version of the Federal Reserve, estimates that bank deposits produce 97% of the U.K.’s money. Moreover, the loan-generating function of private financial institutions described above provides most of those deposits.

So you’re telling me to tell my Paul Krugman-loving cousin, aunt or sister-in-law that banks make money out of thin air? Yes—and most money in the economy is created by the magic wand of banks, not the government.

And what if your Fox News-loving cousin, uncle or brother-in-law argues that “Q.E.” is government money printing? The Federal Reserve is the government’s bank, so it can create money. But in the case of Q.E., it is a swap. The Fed exchanged its own produced cash for bonds. However, when commercial banks make loans, they are not trading assets. They are forming new ones—deposits—out of thin air.

In capitalism, the government’s role in creating new money is limited. It mostly moves around money that is already in the economy, funds itself by collecting taxes or selling government bonds, and then spends that money back into the economy. So most of the money the government touches is already in the economy.

Our government’s primary role in terms of money has evolved into backstopping the bank-produced money. That is what happened in 2008 during the financial crisis. After a five-year binge of money printing by banks in which total mortgage debt doubled from $4 trillion to $8 trillion, the banking system froze as healthier banks were unwilling to honor the payments made by customers of weaker banks. The government had to decide whether to allow the more vulnerable banks to fail, which would have likely brought down the entire financial system, or to step in and guarantee the bank money.

So what does all this mean for this made-up barbecue beef? Both combatants are wrong. Again, in modern capitalistic economies, the banks, not the government, produce most of the new money. Moreover, this ability for private banks to create public funds that go into new dynamic investment has led to many of the advances that make life more enjoyable for all of us today.

Sometimes, though, too much bank money flows toward existing assets, and you get the debt but not the dynamism. In the last economic cycle, bank debt fueled a housing bubble, and, it seems in this period, bank money helped fuel a stock buyback binge and maybe a stock market bubble.

But capitalism’s uniqueness of private banks increasing and steering the public’s money requires a counterbalance of a stable government (football and hockey fans, take note) to backstop, referee, and regulate this bank-created money supply.
