What is Bond Yield? A Simple Guide

A bond yield is the return an investor earns on a bond, expressed as a percentage. It moves inversely to the bond's price: when the price rises, the yield falls, and vice versa. Bond yields reflect interest rates and risk, and are watched as a key signal of market conditions.

A bond pays a fixed amount, but what you actually earn depends on the price you pay. The bond yield captures that real return, and it moves in a way that surprises many.

This guide explains what bond yield is and why it moves opposite to price.

Key Takeaways

• A bond yield is the return earned on a bond, as a percentage.
• It moves inversely to the bond's price.
• Rising prices mean falling yields, and vice versa.
• Yields reflect interest rates and risk.
• They are a key market signal.

What is a bond yield?

A bond yield is the return an investor gets from holding a bond, shown as a percentage. A bond pays fixed interest, but the yield depends on the price paid for it. If you pay less for the same fixed payments, your yield is higher; if you pay more, your yield is lower.

Why does yield move opposite to price?

Because the bond's interest payment is fixed, the return relative to price changes as the price moves. If the price falls, the same fixed payment represents a bigger percentage of what you paid, so the yield rises. If the price rises, the fixed payment is a smaller percentage, so the yield falls.

What do bond yields reflect?

Yields reflect prevailing interest rates and the risk of the bond. When central banks raise rates, yields on new and existing bonds tend to rise. Riskier bonds must offer higher yields to attract buyers. So yields bundle together the cost of money and the compensation demanded for risk.

Why are bond yields watched?

Bond yields, especially on government bonds, are a key signal for the whole economy. Rising yields can mean higher borrowing costs and can weigh on stocks, while falling yields can signal caution or expectations of rate cuts. They influence everything from loan rates to how investors value shares.

How do interest rate changes affect bond yields?

Bond yields are closely tied to expectations for interest rates. When the central bank raises rates or is expected to, yields on existing bonds tend to rise, and their prices fall, since new bonds will pay more. When rates fall, existing bonds with higher fixed payments become more attractive, so their prices rise and yields fall. This is why bond yields react strongly to central bank decisions and to any data that shifts expectations for the path of interest rates.

What do rising bond yields mean for stocks?

Rising bond yields can weigh on shares in two ways. Higher yields raise borrowing costs for companies and can slow the economy, and they also make safer bonds more attractive relative to riskier stocks, drawing some money away. In addition, higher yields reduce the present value of companies' future earnings, which can lower valuations, especially for fast-growing firms. This is why sharp rises in bond yields often unsettle stock markets, linking the two closely.
