Bonds: Lending Your Money

Bonds quietly power a market worth well over a hundred *trillion* dollars—yet most people can’t explain how even a single bond works. Today, you’ll step into the moment you effectively become the bank, and see why your “loan” can suddenly rise or fall in value.

So you already know that when you buy a bond, you’ve stepped into the lender’s role and that the value of that “loan” can bounce around. Now let’s zoom out and see why this quiet corner of the market matters so much to your real life.

Every time a city builds a new school, a company upgrades factories, or a government rolls out infrastructure, there’s a good chance bonds are paying the bill. The terms they lock in today—how long the money is borrowed, at what interest cost, with what level of safety—ripple into mortgage rates, business hiring plans, even the value swings in your retirement account.
