Why Market Rates Change Bond Prices
A bond’s promised dollars can stay fixed while their market value changes. Reprice the same cash flows as the return available in the market moves.
Use present value to connect a market-yield change to bond price, price position, and a one-year investor return.
The bond’s promised dollars arrive in the future. Learn how the market yield translates those future payments into a price today.

Market yield
Market yield is the return investors currently require from a bond with comparable timing and risk.
Present value
Present value is the amount a future payment is worth today after accounting for the return available while waiting.
