Ghana Treasury Bill Rates Surge In August 2026: Latest 91-Day, 182-Day, And 364-Day Auction Results
The Bank of Ghana (BoG) has released the results for the latest treasury bill auction held on August 14, 2026, signaling a renewed upward trend in short-term interest rates. As of August 17, 2026, market yields have adjusted to reflect the government's increased appetite for domestic borrowing to fund infrastructure projects and manage the fiscal deficit for the third quarter. Investors are seeing a marginal increase in the 91-day and 182-day bills, while the 364-day paper remains the highest-yielding short-term instrument in the local market.
| Security Type | Previous Yield (%) | Current Yield (%) | Change (bps) |
|---|---|---|---|
| 91-Day Treasury Bill | 25.10% | 25.45% | +35 |
| 182-Day Treasury Bill | 27.35% | 27.60% | +25 |
| 364-Day Treasury Bill | 30.15% | 30.50% | +35 |
The auction saw a significant oversubscription, with the government exceeding its target of GHS 4.5 billion by approximately 12%. This high demand suggests that despite inflationary concerns in mid-2026, treasury bills remain the safest and most liquid investment vehicle for both institutional and retail investors in Ghana.
Monetary Policy Shifts and Inflationary Pressures Driving Yields
The current trajectory of the treasury bill rate in Ghana today is primarily driven by the Bank of Ghana’s Monetary Policy Committee (MPC) decisions. In the July 2026 review, the BoG maintained the prime rate at 28%, citing a need to anchor inflation expectations as the Cedi faced seasonal pressure against the US Dollar. By keeping the policy rate high, the central bank effectively sets a floor for treasury yields, ensuring that government securities remain attractive relative to commercial bank savings accounts.
Fiscal policy is also playing a critical role in these rate hikes. The Ministry of Finance has ramped up domestic financing targets for the second half of 2026 to bridge the revenue gap caused by fluctuations in global commodity prices, specifically cocoa and gold. As the government competes for limited liquidity within the domestic banking sector, it is forced to offer higher coupons to entice primary dealers and individual investors.
Secondary market activity on the Ghana Fixed Income Market (GFIM) shows that while bond yields have stabilized post-debt restructuring cycles, the short-term end of the curve—the T-bills—remains the most volatile. This volatility provides a tactical advantage for "laddering" investments, allowing savers to roll over shorter-dated 91-day bills into higher-yielding 364-day instruments as rates climb.
Investor Strategies and Accessing Government Securities Digitally
For retail investors looking to capitalize on these 2026 rates, accessibility has reached an all-time high through digital transformation. Most commercial banks and specialized deposit-taking institutions (SDIs) now offer T-bill subscriptions directly via mobile banking apps and USSD codes. The GOG Treasury platform has also been integrated with major mobile money networks, allowing users to invest as little as GHS 50 into the 91-day or 182-day papers.
Strategic allocation in the current environment favors a diversified approach:
- Retail Savers: Focus on the 91-day bill to maintain liquidity, especially with the potential for further rate hikes in Q4 2026.
- Institutional Portfolios: Increasing exposure to the 364-day bill to lock in the 30.50% yield before the anticipated year-end stabilization.
- Risk Management: Investors should account for the 1% to 3% management fees charged by some brokerage firms, which can slightly erode the net effective yield.
Furthermore, treasury bills in Ghana remain exempt from the capital gains taxes that apply to other equity-based investments, making the 30%+ nominal return even more attractive on a tax-adjusted basis. This tax-free status continues to drive the massive retail participation witnessed in the August 2026 auctions.

Economic Forecast and the Q4 2026 Interest Rate Trajectory
Looking ahead to the final quarter of 2026, economists predict that the treasury bill rate in Ghana will likely plateau or see a slight cooling effect. Much depends on the September 2026 inflation data and the subsequent MPC meeting. If the consumer price index (CPI) continues its current downward trend toward the 12% target, the Bank of Ghana may signal a pivot toward a more dovish stance, which would lead to a compression of T-bill yields.
However, the upcoming holiday season often triggers a spike in demand for foreign exchange, which can lead to currency depreciation and force the BoG to keep rates elevated to defend the Cedi. Market analysts suggest that investors should lock in the current 364-day rates now, as the window for 30%+ yields may close if the 2027 budget outlook projects a lower deficit.
The government's commitment to the IMF-supported Post-Covid-19 Programme for Economic Growth (PC-PEG) ensures that fiscal discipline is maintained, which reduces the long-term risk of default on these domestic instruments. For now, the August 2026 auction results confirm that the "T-bill is king" for Ghanaian investors seeking high-yield, low-risk returns in a transitioning economy.
