fractional banking

The banking system in which banks keep only a fraction of deposits in reserve and lend out the rest, creating money through the lending process.

Example

“Under fractional banking, a $1,000 deposit can become $10,000 in loans as money circulates through the banking system.”

Memory Tip

FRACTIONAL banking = banks lend out most deposits, keep only a FRACTION. Creates money supply.

Why It Matters

Understanding fractional banking helps you grasp how the money supply grows and why banks are crucial to economic activity. It explains why your deposits enable loans for others and why bank failures can have cascading effects on the broader economy and your own financial security.

Common Misconception

Many people believe banks simply store their deposits in a vault like a safe deposit box. In reality, banks immediately lend out most deposits to other customers, which is how they generate profits and how the economy gets access to credit for mortgages, business loans, and other needs.

In Practice

If you deposit $1,000 in a bank that maintains a 10 percent reserve requirement, the bank keeps $100 in reserve and lends $900 to another borrower. That borrower deposits the $900 elsewhere, and the second bank keeps $90 and lends $810, creating new money in the system through each lending cycle.

Etymology

FRACTIONAL (only a fraction) BANKING. Banks hold only a FRACTION of deposits in reserve.
