The idea of a check—or promissory note—goes back to antiquity

As long as traders have looked to pay in cash or coin, the idea of an IOU has been close behind. Clay tablets from ancient Mesopotamia (roughly modern Iraq) and Persia (Iran) suggest proto-checks were used at the time. Islamic traders innovated "sakks" in the 9th century, leading to the broader adoption during the Middle Ages in Europe.

The Medicis of Italy innovated 'bills of exchange,' precursors to checks

At the time, lending money for interest (also known as usury) was banned in much of the Christian world. The enterprising Medicis developed bills of exchange to allow merchants to promise payment without cash or coin (with some discrete means of earning interest woven in). Learn more about how this family laid the foundation for modern banking.

London bankers created the first clearinghouse to process checks in 1770

Until that time, each banker was required to bring that day's checks to every other bank for settlement. Perhaps understandably, the first place bankers opted to gather to clear and settle checks was a tavern known as the Five Bells. The innovation gave rise to what would become clearinghouses, key institutions that facilitate payments.

Experts recommend keeping one to two months' worth of expenses in checking

That amount allows you to pay your bills and avoid overdraft fees while ensuring you don't lose interest. Most checking accounts have a near-zero interest rate (0.07% APY on average) while high-yield savings could earn up to 4% as of 2026. Cash sitting in your checking account can mean a loss of hundreds of dollars.

Savings accounts earn more interest and limit monthly transactions

While the checking account is many people's primary daily account, savings accounts can earn customers more in interest, though access to these funds is generally more limited. Customers can earn several percent interest in savings accounts compared to near-zero checking account rates.

Paper check usage is down 83% over 25 years

At the start of the millennium, more than 68 million checks were processed daily. Amid the adoption of automated clearinghouse (ACH) payment systems, that number has sunk to 12 million a day.

Customers wrote just one check a year in 2024, on average

Major retailers like Target have stopped accepting checks in recent years as real-time payment systems are increasingly being implemented across the US. This shift is considered an improvement in safety—as checks are vulnerable to fraud—but can lead to some exclusion for those without access to digital devices.

Banks make money by loaning customer deposits and earning interest

This means the interest you earn on your deposits is lower than what the bank earns on the same amount. Banks often keep cash reserves (though a minimum requirement was rescinded in 2020) but generally invest in government bonds, corporate securities, and loans to other banks. During bank runs, depositors withdraw more than the bank has on hand.

Fractional reserve banking creates deposits from loans, not the other way around

The traditional view of banking is that customers deposit money into the bank and the bank lends out those deposits. That's partly true, but most banks work by making loans first, which creates an asset on their balance sheet as a corresponding deposit. Banks often operate under a money multiplier ratio, lending out several times their total reserves.
