On April 16, 2018, two free market economists debated a topic that has long divided libertarians. Fractional reserve banking refers to banks' standard practice of keeping only a portion of their depositors' money on hand and loaning out the rest. In The Mystery of Banking (1983), the anarcho-capitalist economist Murray Rothbard called fractional reserve banking "a shell game, a Ponzi scheme, a fraud in which fake warehouse receipts are issued and circulate as equivalent to the cash supposedly represented by the receipts." Other libertarian economists, such as Larry White and Steve Horowitz, have argued that the practice is perfectly defensible.

At The Soho Forum, a debate series in New York City that is sponsored by the Reason Foundation, Robert Murphy debated George Selgin over the following resolution: "Fractional Reserve banking poses a threat to the stability of market economies."
