What is bond?

Welcome! I'm excited to help you demystify bonds today. Before we jump into how they work, I'd love to learn a little bit about what brings you here.

What prompted your interest in bonds today, and how much prior experience do you have with investing?

I just want to diversify my personal portfolio.

It's great to meet you! Diversification is one of the smartest reasons to look into bonds. While stocks let you buy a tiny slice of ownership in a company, bonds let you act as the lender, which brings a completely different kind of stability to your portfolio.

The Ultimate IOU

At its core, a bond is simply a formalized —a debt agreement. When a government or a corporation needs to raise money to fund a big project (like building a new highway or expanding a factory), they don't just go to a single bank. Instead, they issue bonds to the public.

By purchasing a bond, you are lending your hard-earned cash directly to that issuer. In return, they legally promise to make regular interest payments to you for a set period, and then hand your original loan amount right back to you when that time is up.

I've put together a quick visualization above to show this basic flow of cash. To make sure we're speaking the same language as the pros, there are a few essential terms we should lay out next.
