The shadow banking system is a group of intermediaries that operate outside of normal banking regulations

Near-universal banking masks a large underbanked shadow system

FDIC data indicates 128 million households have a checking account, the vast majority (96% in 2024). But more than 14% of households are underbanked, meaning they have accounts but also rely on nonbank services such as check cashing, payday loans, or prepaid cards.

Before the modern banking system, most lending resembled private credit

Before the creation of the modern banking system, the majority of loans were negotiated directly between the lender and the borrower—effectively making them private credit transactions.

Private credit is a nonbank loan made directly to a business

Similar to private equity, private credit is part of the private markets world. Both strategies offer illiquid, privately negotiated investments for privately held companies. Unlike private equity investors, however, private credit investors typically do not take ownership stakes in the companies they invest in.

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.

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.

Securitization has become common practice in home financing

When a homebuyer finances with a lender, they aren’t necessarily the one footing the bill. After a buyer secures a home loan, the lender can sell the loan to another financial institution or a private institution. That group can later sell that mortgage to investors. This is called securitization.

Investors need a 'margin account' to short sell stock

Margin accounts are leveraged accounts through brokerage firms that allow investors to make trades without the full amount of capital on hand. Similar to a secured loan, margin accounts often require some form of collateral and typically have a cap on how much investors can borrow. However, trading with a margin account is much riskier than a traditional investment account. Fees and charged interest are due on margin accounts, regardless of trade performance, meaning it's possible for investors to lose more money than just their initial investment.

The Fed operates within the open market as a competitive bidder of interest rates

Because it’s viewed as a risk-free platform to earn interest, whatever rate it sets becomes the default benchmark. To maintain its target rate prescribed by the Federal Open Market Committee, the Fed has various tools it offers both commercial banks and home loan institutions.

BNPL may be adding a layer of debt that doesn't show up in economic data

Given somewhat limited regulation in the BNPL space, data about its usage is limited—many BNPL firms have resisted sharing information about user purchases, finances, and more thus far.

Modern payday lending came about in the late 1990s

In the early 1900s, unlicensed "salary lenders" used to give consumers one-week loans at annualized percentage rates of more than 100%. But wage garnishment and financially abusive practices led some states to create special licenses for lenders and implement rate caps to protect consumers. In the 1990s, a series of deregulations in various states opened the door for the modern payday lending industry to take off.

The Glass-Steagall Act separated commercial banks in the US from investment banks

Card issuers are financial institutions that open credit to customers, while card networks facilitate purchases between merchants and customers

These networks make money on interchange fees, which merchants pay to accept a specific card network at their stores.
