convertible bond

Two people lend money to a cousin who is starting a small business. The first one says, just pay me back with interest, I want my money safe and predictable. The second one says, pay me interest too, but if this business becomes big, let me trade my loan for a piece of the company instead of the cash. That second cousin holds something very close to a convertible bond.

A convertible bond is a bond, which means the company borrows money from you and promises regular interest plus your capital back at a set date. But it carries an extra privilege. At certain points, you can choose to convert that bond into a fixed number of shares in the company instead of collecting the cash. You get the safety of a lender at first, with the option to become an owner later if the shares rise enough to make that swap worth it.

Say a Nigerian tech company issues a convertible bond to raise ₦500,000,000 for expansion. An investor buys ₦2,000,000 worth, earning 8% yearly interest. The bond can later convert at ₦50 per share. If the company grows and its shares climb to ₦90, the investor converts, turning that ₦2,000,000 loan into shares worth far more than the cash payout would have been. If the shares never rise past ₦50, the investor simply keeps collecting interest and takes their principal back at maturity, no harm done.

In the United Kingdom, convertible bonds are popular with growth companies that want to borrow cheaply. Because investors get the sweetener of possible conversion into shares, the company can often offer a lower interest rate than a plain bond would need, which keeps borrowing costs down while it grows.

For someone abroad sending money home to invest, a convertible bond can feel like a good middle ground. You are not fully exposed to share price swings like a pure shareholder, but you are not locked out of the upside either. It rewards patience without demanding you bet the whole amount on the company's success.
