What is a bond?

A bond is a loan packaged as something you can buy and sell. When a government or a company wants to borrow money, it issues bonds. You hand over a sum of money, the issuer promises to pay you interest at set times, and it promises to give back your original amount on a fixed date, called the maturity date.

What makes bonds interesting is that they trade after they are issued, and their prices move. When prevailing interest rates rise, older bonds that pay less become less attractive, so their prices tend to fall. When rates fall, the reverse happens. Bonds also carry risk: an issuer can fail to pay, which is why borrowers with shakier finances usually have to offer higher interest. Because of all this, bonds sit quietly under mortgages, government budgets and retirement accounts.

An episode would start with the plain loan idea, then walk through the vocabulary: face value, coupon, maturity and yield. It would explain why price and yield move in opposite directions, and how governments, cities and companies use bonds. This page comes from bre, an app whose hosts are AI, so they can make mistakes. The episode explains how bonds work. It does not tell you what to buy.

What a bre episode would cover

An outline of the episode bre would make for this question. Every episode is written fresh when you ask, so yours will differ.

  1. A loan you can tradeThe basic deal: you lend money, the issuer pays interest and returns your principal at maturity. Why that promise can be bought and sold.
  2. Face value, coupon and maturityThe three words that describe almost every bond, shown with a simple worked example.
  3. Who issues bondsFederal governments, cities and companies all borrow this way. Each offers a different mix of safety and reward.
  4. Why prices and yields move opposite waysWhen market interest rates rise, existing bonds look less appealing and their prices tend to drop. A slow walk through the seesaw.
  5. Credit risk and ratingsWhat happens if an issuer cannot pay, and how rating agencies try to describe that risk. Why riskier borrowers pay more.
  6. Bonds versus stocksLending versus owning a slice of a business. How the two differ in claims, income and ups and downs.
  7. Where you already meet bondsBond funds, pensions and the market that sets many borrowing costs. Explained, not advised.

How the episode might open

A sample exchange between two of bre’s AI hosts, bre and Tess. Both are AI; this is written by AI, as every bre episode is.

  1. breAI host

    Okay, I'll start with a confession. For years I nodded along when people said "bonds" and had no picture in my head at all.

  2. TessAI host

    Same. It sounds like something a man in a vest says on TV. So what is it, really?

  3. breAI host

    It's an IOU. A government or a company needs cash, so it borrows from lots of people at once, and each person gets a certificate saying how much they lent and when they get it back.

  4. TessAI host

    So I'm the bank. Do I get paid for that?

  5. breAI host

    Interest, usually at regular intervals. Then on the maturity date, you get your original amount back. Assuming the borrower can pay, which is the part to watch.

  6. TessAI host

    Okay, but real talk. If it's just a loan, why does everyone act like bond prices are some mystery?

  7. breAI host

    Because you can sell that IOU before it matures, and what someone will pay for it changes every day. That's the strange bit.

  8. TessAI host

    Strange how? Walk me through it slowly, like I'm holding the paper.

Questions people also ask

Is a bond the same as a stock?
No. A bond is a loan: you are a lender, owed interest and your money back at maturity. A stock is a share of ownership in a company, with no promised payment. Both can rise or fall in price, but the claims differ.
Why do bond prices fall when interest rates rise?
If new bonds pay higher interest, an older bond paying less looks worse by comparison. To attract a buyer, its price has to drop so the buyer's overall return catches up. That is why prices and yields move in opposite directions.
Can you lose money on a bond?
Yes. The issuer could fail to pay, or you could sell before maturity at a lower price than you paid. Holding a bond to maturity from a reliable issuer avoids the price swings, but not every risk. This is explanation, not advice.
What is a coupon on a bond?
The coupon is the fixed interest payment a bond makes, usually stated as a percentage of its face value. The name comes from old paper bonds that had detachable coupons holders turned in to collect their interest.
