What Is a Premium Bond?

5 Min.

A premium bond is a type of bond that has a market value higher than its face value. This can happen when the bond's interest rate exceeds the prevailing market interest rates. Moreover, a higher credit rating of the issuing company and the bond itself can also contribute to the bond being traded at a premium. When the issuer of a bond is financially sound and creditworthy, investors are willing to pay more for such a bond.


Premium bonds, trading at values surpassing their face amounts, reflect a market scenario where their costs exceed nominal values. The driving force behind a bond commanding a premium lies in its interest rate surpassing prevailing market rates. This stands in contrast to a distinct financial instrument in the United Kingdom, commonly known as a premium bond, associated with lottery bond accounts.

Premium Bonds Unveiled

When a bond commands a premium in the market, it indicates that its price exceeds the nominal or face value. For instance, a bond initially valued at $1,000 may trade at $1,050, representing a $50 premium. Despite having a maturity period of ten years, these bonds are actively traded in the secondary market, enabling investors to engage in buying and selling well before maturity. Upon reaching maturity, the investor realizes the face value, such as the $1,000 in the example above.

Furthermore, a premium bond denotes a distinct bond category in the United Kingdom. Within the British government's National Savings and Investment Scheme, a premium bond is synonymous with a lottery bond.

Bond Premiums and Interest Rate Dynamics

Understanding the interplay between bond premiums and interest rates is essential for investors. Bond prices and interest rates have an inverse relationship. When interest rates fall, bond prices rise; when interest rates increase, bond prices drop.

Most bonds adhere to fixed-rate structures, implying that the interest paid remains constant throughout the bond's lifespan. Regardless of fluctuations in market interest rates, bondholders receive the predetermined coupon rate, providing a sense of stability in interest payments.

Fixed-rate bonds become particularly appealing in a declining market interest rate scenario, as existing bonds offer higher rates compared to newly issued bonds with lower rates. For instance, if an investor holds a $10,000 4% bond maturing in ten years, and market interest rates subsequently drop, the investor possesses a premium asset. Should the investor opt to sell this bond, it would command a premium higher than its $10,000 face value in the secondary market.

The dynamic shifts when interest rates rise. Newly issued bonds reflect the elevated rates, pushing bond yields higher. Investors, anticipating further rate increases, seek higher yields, leading to a decline in the secondary market prices of older, lower-yielding bonds. Consequently, these bonds are traded at a discount.

Credit Ratings' Impact on Bond Premiums

The company's credit rating significantly influences a bond's pricing and offered coupon rate. A credit rating assesses a borrower's general creditworthiness, encompassing both overall financial health and specific debt obligations.

Strong company performance typically attracts investor interest, leading to a bond price rise. Investors, valuing the creditworthiness of a financially sound issuer, are willing to pay a premium for its bonds. Bonds from well-managed companies with stellar credit ratings often command prices above their face values, a trend appealing to risk-averse bond investors.

Credit-rating agencies play a pivotal role in evaluating the creditworthiness of corporate and government bonds, providing investors with a risk overview. These agencies employ letter grades to communicate ratings; for instance, Standard & Poor's uses a scale ranging from AAA (excellent) to C and D. Bonds rated below BB are deemed speculative or junk bonds, indicating a higher likelihood of loan default. This credit rating serves as a crucial metric for bond investors, guiding their risk assessment decisions.

Premium Bond Yield Dynamics

The coupon rate on a premium bond often exceeds prevailing market interest rates. However, the additional premium cost above the bond's face value can impact the effective yield, potentially presenting challenges for investors. Effective yield presupposes reinvesting coupon payments at the bond's rate, a feasibility that diminishes in a declining interest rate environment.

The bond market's efficiency aligns the bond's current price with prevailing interest rates relative to its coupon rate. Understanding the reason behind a bond's premium, whether linked to market rates or the issuer's credit rating, is crucial for investors. While a high premium may offer added yield compared to the market, the risk of overpayment looms if market rates surge after acquiring the premium bond.


  • Premium bonds generally offer a superior interest rate compared to the broader market.
  • Typically issued by well-managed firms with robust credit ratings.


  • The elevated price of premium bonds offsets their higher coupon rates to some extent.
  • Investors face the risk of overpaying for an overvalued premium bond.
  • Potential overpayment risk increases if market rates experience significant upswings.

Premium Bond Example

Consider Apple Inc. (AAPL), which issues a 10-year bond with a face value of $1,000, boasting a 5% interest rate and holding a AAA credit rating from credit rating agencies. Notably, the Apple bond's interest rate surpasses the 10-year Treasury yield, prompting a premium in the secondary market, where it trades at $1,100 per bond. Consequently, investors receive a 5% annual return on their investment. The premium reflects the additional price investors are willing to pay for the enhanced yield offered by the Apple bond.


Premium bonds, characterized by a market value exceeding face value, result from elevated interest rates or a superior credit rating. The interplay of interest rate fluctuations and creditworthiness influences market prices, presenting both potential returns and risks.
