Full-reserve banking

Full-reserve banking (also known as 100% reserve banking) is a system of banking where banks do not lend demand deposits and instead only lend from time deposits. It differs from fractional-reserve banking, in which banks may lend funds on deposit, while fully reserved banks would be required to keep the full amount of each customer's demand deposits in cash, available for immediate withdrawal.

Monetary reforms that included full-reserve banking have been proposed in the past, notably in 1935 by a group of economists, including Irving Fisher, under the so-called "Chicago plan" as a response to the Great Depression. This proposal experienced a resurgence of interest among economists, central bankers, and citizen movements following the 2007-2008 global financial crisis.
