Ghana Bonds vs Treasury Bills: Understanding the Risk Difference

Treasury bills and government bonds are both loans to the Republic of Ghana. But they carry fundamentally different risks. One is a short-term parking space with minimal price sensitivity. The other is a long-term commitment where interest rate movements, inflation, and sovereign credibility all shape your outcome. Understanding this distinction is essential before you decide where your money should sit.

The Core Risk Distinction: Duration

The most important difference between the two instruments is duration—how long your money is locked up, and therefore how sensitive your investment is to changes in interest rates.

Treasury bills mature in 91, 182, or 364 days . You buy at a discount and receive face value at maturity. Because the holding period is short, the price you receive is largely predetermined. Interest rate movements during your holding period have little effect on your outcome if you hold to maturity.

Government bonds mature in two years or more . They pay periodic coupons and return principal at maturity. Because the cash flows are spread over years, the bond’s market price is highly sensitive to interest rate changes. A bond with a 9.10% coupon maturing in February 2032 was trading at a price of 80.88 in October 2026, with a yield of 14.31%—a discount that reflects both the coupon being below market rates and the risk premium investors demand .

This is duration risk. The longer the bond, the more its price moves when rates change.

The Interest Rate Risk in Practice

Ghana’s market in 2026 illustrates the dynamic clearly.

The Bank of Ghana cut its policy rate aggressively, from 28% in June 2025 to 14% by March 2026 . Short-term Treasury bill yields collapsed. The 91-day bill fell to about 4.64%, and the 364-day bill to about 9.80% . With inflation at 5.2%, the 91-day bill now offers a negative real return .

Investors holding short-term bills are losing purchasing power. But they are not exposed to price risk—if they hold to maturity, they get their face value back.

Bondholders face a different calculus. As rates fell, the prices of existing bonds rose. But if rates were to rise again, those prices would fall. The February 2032 DDEP bond saw its yield rise from 14.23% to 14.91% in a single session, with the price falling to 79.08—a 68-basis-point move that illustrates how quickly long-dated bond prices can shift .

For an investor who needs to sell before maturity, that price movement is a real loss. For one who holds to maturity, it is only a paper loss.

The Inflation Risk

Treasury bills and bonds both carry inflation risk, but the exposure differs.

A 91-day bill locks in your return for three months. If inflation rises during that period, your real return falls—but you can reinvest at the new, higher rates relatively quickly.

A long-dated bond locks in your coupon for years. If inflation rises significantly, the fixed coupon becomes less valuable in real terms. The 2022 crisis, when Ghana’s inflation surged past 50%, wiped out the real value of fixed-income returns for anyone holding long-duration paper.

The current environment offers some protection. DDEP bonds yield 13.86% to 14.93%, well above inflation of 5.2% . That provides a positive real return. But the margin can compress if inflation rises.

The Sovereign Credibility Risk

This is the risk that distinguishes Ghana from developed markets.

Treasury bills and bonds are both claims on the same sovereign. The 2022 Domestic Debt Exchange Programme restructured domestic debt, imposing losses on bondholders—including pension funds, which had GH¢31 billion restructured . The DDEP was unprecedented on the African continent, and it shattered the assumption that Ghanaian government debt was risk-free.

Since then, the government has worked to rebuild credibility. A Cedi Sinking Fund had accumulated GH¢15.6 billion by July 2026, targeting GH¢30 billion by end-2026 to cover the GH¢111 billion in maturities falling due in 2027 and 2028 . The government has returned to the bond market, issuing a seven-year bond at a 12.5% coupon—significantly above the 364-day bill rate of 9.77% at the time, a premium that reflects lingering investor caution .

Both instruments carry sovereign risk. But bondholders have more at stake over a longer period. A default or restructuring event five years from now would hit a 2032 bond far harder than a 91-day bill that matures in three months.

The Liquidity Risk

Treasury bills are highly liquid. The secondary market for bills is active, with GH¢117 billion traded in 2024—about 68% of all fixed-income market activity . You can sell a bill before maturity with relative ease.

Bonds are less liquid. Trading is concentrated in a handful of DDEP securities. In one October 2026 session, the February 2032 bond recorded GH¢400 million across just two transactions, accounting for over 39% of the entire market’s trading value . The rest of the market was largely inactive.

This concentration means that selling a bond position quickly may require accepting a discount. As one international investor described it, the local bond market can feel like a “Hotel California” trade—one you can enter, but not leave .

Which Risk Matters Most?

It depends on your time horizon and your need for certainty.

If you need your money within a year, Treasury bills are the safer choice. You are not exposed to price risk, and the liquidity is there if you need to exit early.

If you can lock up your money for two years or more, bonds offer higher yields and positive real returns. But you accept duration risk, inflation risk, and the sovereign credibility risk that comes with lending to Ghana for longer.

The current market is pricing that risk explicitly. The gap between the 91-day bill at 4.64% and the February 2032 DDEP bond at 14.51% is roughly 1,000 basis points . That is the premium the market demands for duration and sovereign risk.

Whether that premium is adequate depends on your view of Ghana’s fiscal trajectory, inflation, and the government’s willingness to honour its obligations.

Quick Facts

Frequently Asked Questions

1. What is the main risk difference between Ghana bonds and Treasury bills?
The main difference is duration. Treasury bills mature within a year, so they carry minimal interest rate price risk if held to maturity. Bonds mature in two years or more, exposing holders to significant price movements when interest rates change .

2. Are Treasury bills safer than bonds in Ghana?
For short-term certainty, yes. T-bills are less sensitive to interest rate changes and more liquid. But with the 91-day bill yielding below inflation, they offer negative real returns. Bonds carry more price risk but offer higher yields and positive real returns .

3. What is interest rate risk for bonds?
When market interest rates rise, the price of existing bonds falls because their fixed coupons become less attractive. The longer the bond’s duration, the larger the price swing. A 2032 bond moved 68 basis points in yield in a single session in October 2026 .

4. What happened to Ghanaian bonds in the 2022 debt restructuring?
The Domestic Debt Exchange Programme restructured domestic debt, imposing losses on bondholders. Pension funds had GH¢31 billion restructured. The event shattered confidence in Ghanaian government debt as a risk-free asset .

5. Which is more liquid: Treasury bills or bonds?
Treasury bills are more liquid. They accounted for about 68% of Ghana Fixed Income Market trading in 2024. Bond trading is concentrated in a few DDEP securities, and selling a large position quickly may require a discount .

6. Do both instruments carry inflation risk?
Yes. But T-bills lock in returns for only a few months, allowing quicker reinvestment if inflation rises. Bonds lock in coupons for years, so rising inflation erodes the real value of those payments over a longer period.

7. What is the current yield gap between T-bills and bonds?
The 91-day bill yields about 4.64%, while the February 2032 DDEP bond yields about 14.51%—a gap of roughly 1,000 basis points. That premium reflects duration risk and sovereign credibility concerns .

8. Should I buy bonds or T-bills in Ghana?
It depends on your time horizon. If you need liquidity within a year, T-bills are safer. If you can lock up your money for two years or more and want positive real returns, bonds offer higher yields—but with more risk.
