Sachin is experiencing interest rate risk, which is the risk that changes in interest rates will affect the value of fixed income securities. When interest rates rise, bond prices fall, and vice versa. This is because investors will demand a higher yield to invest in bonds that pay a lower coupon rate than the prevailing market rate. Therefore, if the Bank of Canada makes it more expensive to borrow money, the existing bonds in Sachin’s fund will become less attractive and their prices will drop. Interest rate risk is measured by a fixed income security’s duration, with longer-term bonds having a greater price sensitivity to rate changes. Sachin can reduce his interest rate risk by diversifying his bond maturities or hedging using interest rate derivatives1.
