INTEREST RATE RISK

Interest Rate Risk and Its Impact on Investment Returns

Interest rate risk is the possibility that changing interest rates will affect the value, income or performance of an investment. It is especially important for bond investors, but rate changes can also influence stocks, real estate, borrowing costs and broader portfolio valuations.

UNDERSTANDING INTEREST RATE RISK

Why changing rates can change the value of an investment

Interest rates influence the cost of borrowing, the value of future cash flows and the attractiveness of different investments. Understanding these relationships can make portfolio risk easier to evaluate.

01

The basic relationship between rates and bond prices

For many existing fixed-rate bonds, market prices generally move in the opposite direction from prevailing interest rates. When newly issued bonds offer higher yields, an older bond with a lower fixed coupon may become less attractive. Its market price may therefore fall so that its overall yield is more competitive with newer bonds.

The reverse can happen when market interest rates decline. Existing bonds with higher fixed coupon payments can become relatively more attractive, which may support their market prices.

Simple rule to remember

For many fixed-rate bonds, prices and market interest rates generally move in opposite directions.

Rates ↑ Bond prices may fall

Rates ↓ Bond prices may rise

The actual price response depends on factors such as maturity, coupon, duration, credit quality and market expectations.

WHAT DRIVES RATE RISK

Several factors determine how strongly an investment responds to rate changes

Interest rate risk is not identical across every bond or portfolio. The maturity, duration, coupon and structure of an investment can all influence its sensitivity.

01

Duration

Duration is one of the most useful measures for understanding a bond's sensitivity to changes in interest rates. In general, bonds with higher duration tend to experience larger price movements for a given rate change.

Higher Duration Greater Rate Sensitivity
Bond Maturity

Longer-maturity bonds can generally have greater exposure to changes in market rates.

02
Coupon Rate

The size and timing of a bond's cash flows can affect its sensitivity to interest-rate movements.

03
Yield Environment

The relationship between current yields and existing bond coupons can affect market pricing.

04
Cash Flow Timing

Investments receiving more cash flows sooner can have different rate sensitivity than investments with distant cash flows.

05
WHEN INTEREST RATES CHANGE

The effect can spread across different parts of the economy

Interest rates do more than influence bond prices. They can affect borrowing costs, business investment, consumer spending, real estate activity and the valuation of financial assets.

01

Bonds

Existing fixed-rate bonds can experience price changes when market yields move. Longer-duration bonds can be particularly sensitive.

02

Stocks

Higher rates can influence company financing costs, consumer demand and the present value investors place on future earnings.

03

Real Estate

Mortgage rates and financing conditions can influence property affordability, demand, investment activity and valuations.

04

Cash & Savings

Interest-rate changes can affect yields available on savings accounts, certificates of deposit and other cash-oriented products.

WHY BONDS ARE SENSITIVE

A fixed payment becomes more or less attractive as market yields change

Consider a hypothetical bond paying a fixed annual coupon. If new bonds begin offering higher yields, investors may demand a lower price for the older bond to compensate for its relatively smaller coupon.

If market yields decline instead, the older bond's fixed payment can become more attractive compared with newly issued securities, which can support its market price.

Rates Rise Existing bond prices may decline.
Rates Fall Existing bond prices may increase.
DURATION AND RATE SENSITIVITY

Duration can help explain why some bonds move more than others

Duration is not a guarantee of how much a bond will move, but it provides a useful way to compare interest-rate sensitivity across fixed-income investments.

LOWER SENSITIVITY
HIGHER SENSITIVITY
1
Short Duration

Generally less sensitive to rate changes than longer-duration bonds.

2
Intermediate Duration

Offers a middle ground between shorter and longer interest-rate exposure.

3
Long Duration

Generally more sensitive to changes in market interest rates.

Actual bond price movements depend on duration, convexity, yield changes, credit conditions and other market factors.
MANAGING INTEREST RATE RISK

Ways to manage rate exposure without ignoring your investment goals

Managing interest rate risk does not necessarily mean avoiding bonds or interest-sensitive investments. It means understanding the exposure and matching it with your time horizon, income needs and risk tolerance.

01

Diversify Interest Rate Exposure

Holding investments with different maturities and rate sensitivities can reduce dependence on one particular rate environment. Diversification should be considered alongside credit quality, asset allocation and overall portfolio objectives.

BALANCED EXPOSURE
RATE ENVIRONMENTS

Different rate environments can create different investment conditions

The same portfolio can behave differently when interest rates are rising, falling or moving within a narrow range.

01

Rising Rates

Existing fixed-rate bond prices may face pressure as newly issued securities begin offering higher yields. Borrowing costs can also increase.

Higher Rate Pressure
03

Stable Rates

When rates remain relatively stable, other factors such as credit quality, economic growth and issuer fundamentals may become more prominent.

Lower Rate Movement
COMMON MISTAKES

Interest rate risk becomes easier to manage when you know where it hides

Investors sometimes focus on coupon income without considering how market rates can affect the value and future opportunity cost of a fixed-income investment.

01

Looking Only at Coupon Income

A bond's coupon tells you about its scheduled interest payment, but it does not tell you everything about market-price sensitivity or total return.

02

Ignoring Duration

Two bonds can have similar credit quality but very different sensitivity to interest-rate movements because their durations differ.

03

Assuming All Bonds React the Same

Treasury securities, corporate bonds, municipal bonds and other fixed-income investments can have different risk characteristics.

04

Forgetting Reinvestment Risk

When rates fall, investors receiving coupons or maturing principal may have to reinvest that money at lower available rates.

Frequently asked questions about interest rate risk
FREQUENTLY ASKED QUESTIONS

Common questions about interest rate risk

Interest rate risk is the possibility that changes in market interest rates will affect the value, income or performance of an investment. It is most commonly associated with fixed-income securities such as bonds.

When new bonds are issued with higher yields, existing bonds with lower fixed coupons can become less attractive. Their market prices may decline so that their effective yield becomes more competitive with newer securities.

When market rates decline, existing fixed-rate bonds with higher coupons can become relatively more attractive. Their market prices may rise, although the actual result depends on the bond and market conditions.

Duration is a measure commonly used to estimate a bond's sensitivity to changes in interest rates. In general, a bond with higher duration tends to experience larger price movements for a given change in rates.

Yes. Changes in interest rates can influence borrowing costs, consumer demand, business investment and the value investors place on future corporate earnings. The impact varies by company and market environment.

Interest rate risk generally cannot be eliminated completely. Investors can manage exposure by considering maturity, duration, diversification, asset allocation and the time horizon for which the money is invested.
