Guinea-Bissau's bond market is mainly made up of government Treasury bills and Treasury bonds issued through the regional WAEMU market. Recent auctions show that longer-term securities can offer higher yields, but the extra return comes with greater maturity and sovereign risk.
Treasury Bills
- Short-term Treasury bills are generally issued for less than one year.
- Recent 12-month bills have produced yields around 5.6%–6.2%, depending on the auction.
- They can suit investors who want shorter maturities and lower interest-rate exposure.
Treasury Bonds
- Three-year Treasury bonds have recently offered higher yields than short-term bills.
- A March 2026 auction produced a weighted-average yield of about 8.46% on the 3-year bond.
- A July 2026 auction produced about 7.68%, showing that yields can change significantly between auctions.
- Longer maturity therefore does not guarantee the same return every time.
Why Higher-Yield Bonds Can Be Attractive
- Higher yields provide greater potential income.
- Longer bonds can lock in attractive rates for several years.
- They may be useful for investors who can hold the security until maturity and do not need immediate access to the money.
Risks to Consider
- Sovereign risk: Guinea-Bissau has faced elevated public and external debt risks, so higher yields should not be viewed as free extra income.
- Maturity risk: Longer bonds can be more sensitive to changes in interest rates.
- Liquidity: Selling before maturity may be difficult or may require accepting a lower price.
- Currency: Government securities are generally denominated in CFA francs, so investors using another currency should consider exchange-rate movements.
- Reinvestment risk: Short-term bills may mature sooner, forcing investors to reinvest at potentially lower rates.
How to Choose
For a conservative investor, shorter Treasury bills may provide a better balance between return and maturity risk. Investors willing to accept more risk and lock up their money longer may consider 2–3 year Treasury bonds, particularly when the yield premium over short-term bills is attractive.
Conclusion
The strongest recent yields in Guinea-Bissau have generally been found in longer-term Treasury bonds rather than the shortest Treasury bills. However, investors should not select a bond based only on its advertised yield. Maturity, sovereign risk, liquidity, inflation, currency exposure and the ability to hold until maturity should all be considered before choosing a security.
