How banking works

To do big things, people often need more money. Banks jumpstart economic activity with loans paid back with interest, and when things are working well, both people and the bank make more money. Formed in the Middle Ages amid competing currencies in Italy, banks—from the Italian for bench, banco—helped stimulate that era's commercial revolution, a massive expansion in Mediterranean trade and development. Find out the ins and outs of banks in this quick explainer video.

Explaining the collapse of Silicon Valley Bank

In March 2023, Silicon Valley Bank—the nation's 16th largest bank at the time—collapsed after a rapid run on its deposits. Among other factors, the bank had placed more than half of its investments into long-term bonds, leaving it without the necessary cash on hand as its clients, largely start ups, panicked and withdrew their money at the same time. This visualization lays out the timeline and impact of the collapse.

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 Banks often keep cash reserves (though a minimum requirement was rescinded in 2020) but generally invest in government bonds, corporate securities, and loans to other banks.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.

Since the 1990s, banks have sold some of the credit risk of their accounts to external investors, known as SRTs, or synthetic risk transfers

This means if the account defaults, the outside investors assume most of the risk in return for some regular payments, freeing up the bank's ledger. It is a form of insurance used by banks to allow them to free up capital. In 2024, nearly $100B worth of SRT notes were sold.

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.
