Two numbers, often confused, describe very different things. One is fixed at issuance and never changes. The other moves every day, shaped by market forces. Understanding the difference is essential for anyone investing in Ghana’s bond market.
The Core Distinction
The coupon rate is the interest rate the government promises to pay on a bond’s face value. It is set when the bond is issued and remains fixed for the life of the bond.
The yield is the return an investor actually earns, based on the price paid for the bond. It changes as market prices move.

The coupon is the promise. The yield is the reality.
Coupon Rate: The Fixed Promise
When Ghana issues a bond, it specifies a coupon rate. That rate determines the periodic interest payments—known as coupons—that the bondholder receives.
Government of Ghana bonds pay coupons semi-annually . A bond with a 12% coupon and a face value of GH¢50,000 pays GH¢6,000 per year, or GH¢3,000 every six months.
The coupon is calculated on the face value of the bond, not on the price you paid. This is critical. Whether you buy the bond at GH¢45,000 or GH¢55,000, the coupon payment remains GH¢6,000 per year. The coupon does not change.
The coupon rate is fixed at issuance. It does not respond to inflation, interest rate changes, or market sentiment. It is a contractual obligation.
Yield: The Moving Reality
The yield is what you actually earn. It depends on the price you pay for the bond.
If you buy a GH¢50,000 bond with a 12% coupon at its face value, your yield is 12%. The coupon and the yield are the same.
But bonds trade on the secondary market. Their prices move.
If you buy that same bond for GH¢45,000—a discount—you still receive GH¢6,000 per year in coupon payments. On a GH¢45,000 investment, GH¢6,000 represents a 13.3% yield. Your coupon is still 12%, but your yield is higher because you paid less.
If you pay GH¢55,000—a premium—the same GH¢6,000 coupon represents a 10.9% yield. You paid more, so your return is lower.
The relationship is inverse: when bond prices rise, yields fall. When prices fall, yields rise.
Why This Matters in Ghana’s Market
The distinction between coupon and yield has become particularly important in 2026.
Ghana’s fixed-income market has shifted dramatically. Short-term Treasury bill yields have collapsed. The 91-day bill now yields about 4.64% and the 364-day bill about 9.80% . With inflation at 5.2%, the 91-day bill offers a negative real return.
Longer-dated bonds tell a different story. Newly issued four-year government bonds trade around 11.41% . Restructured DDEP bonds offer significantly higher yields on the secondary market :
| Maturity | Yield |
|---|---|
| February 2029 | ~13.86% |
| February 2030 | ~14.20% |
| February 2032 | ~14.51% |
| February 2037 | ~14.93% |
These yields are not coupon rates. They are market-determined returns based on current prices. The coupons on these bonds were set at issuance—often in the 8% to 10% range under the DDEP restructuring. The higher yields reflect the fact that the bonds are trading at discounts to their face value.
An investor buying a DDEP bond at a yield of 14.37% is not receiving a 14.37% coupon. They are receiving the bond’s original coupon (perhaps 9% or 10%) plus a capital gain when the bond matures at face value. The yield captures both components.
The Formula, Simplified
For a bond held to maturity, the yield to maturity (YTM) is the discount rate that equates the present value of all future cash flows—coupons plus principal—to the current market price.
The formula is complex. The intuition is simple:
-
If you pay less than face value, your yield is higher than the coupon.
-
If you pay more than face value, your yield is lower than the coupon.
-
If you pay face value, your yield equals the coupon.
Which Number Should Investors Watch?
Both matter, but they serve different purposes.
The coupon rate tells you the cash flow you will receive. It is what you budget around. If you need GH¢6,000 per year in income, a 12% coupon on GH¢50,000 delivers that.
The yield tells you the return on your investment. It is what you compare against other opportunities. If a corporate bond offers a 15% yield and a government bond offers a 14% yield, the yield is the number that matters for your decision—assuming similar risk.
In a falling interest rate environment, yields on existing bonds fall as prices rise. Investors who locked in higher coupons benefit from capital appreciation. In a rising rate environment, yields rise as prices fall, and existing bondholders suffer capital losses.
The Tax Advantage
For individual investors in Ghana, interest income on government securities is exempt from tax . This applies to both Treasury bills and government bonds.
The exemption means the yield you see is the yield you keep. There is no withholding tax deducted at source. For investors comparing government bonds to bank deposits or corporate bonds—where interest is taxable—this exemption is a significant advantage.
ASJ Bottom Line
The coupon rate is fixed. The yield moves. The coupon is the promise; the yield is the reality.
In Ghana’s current market, with short-term bill yields below inflation and longer-dated bonds offering double-digit yields, understanding the distinction is not academic. It is the difference between knowing what you will receive and knowing what you will earn.
The coupon is what the government pays. The yield is what the market gives. And in a market as dynamic as Ghana’s, the yield is where the opportunity—and the risk—actually lives.
