Ghana Treasury Bills See Record Oversubscription as Yields Plunge

Key Takeaways

• Investor demand for Ghana T‑bills surged 26.5% week‑on‑week, reaching GH¢14.27 billion.
• Auction oversubscribed by 162.9%, with the Treasury accepting GH¢5.85 billion, 7.86% above target.
• Yields on 91‑day, 182‑day and 364‑day bills fell 39, 19 and 91 basis points to 5.08%, 7.08% and 11.59% respectively.
• Analysts link demand to improved liquidity from the Domestic Debt Exchange Programme coupon payment.

Strong investor appetite reshaped Ghana’s short‑term debt market last week, pushing bid volumes well beyond the Treasury’s expectations. The resulting oversubscription forced yields on all three benchmark bills to retreat sharply.

Market participants cite the recent liquidity boost from the Domestic Debt Exchange Programme as a catalyst for the shift toward the 364‑day instrument, where yields remain comparatively attractive.

Market Dynamics and Auction Results

The Treasury announced a GH¢5.15 billion issuance plan covering 91‑day, 182‑day and 364‑day bills to refinance maturing obligations of GH¢5.08 billion. Bids totaling GH¢14.27 billion eclipsed the GH¢5.43 billion target, marking a 26.5% weekly increase.

Oversubscription reached 162.89%, prompting the Treasury to accept GH¢5.85 billion—7.86% above the original target. The excess demand compressed yields across the curve, with the 91‑day rate slipping to 5.08% and the longest‑dated 364‑day rate to 11.59%.

Liquidity Drivers and Investor Behavior

Analysts attribute the surge to the Domestic Debt Exchange Programme’s recent coupon distribution, which restored cash flow to institutional investors. With improved liquidity, market actors rotated into longer‑dated bills to lock in yields before further compression.

Databank Research notes that the supportive liquidity environment is likely to sustain demand, reinforcing downward pressure on short‑term rates. The preference for the 364‑day bill reflects a strategic balance between yield capture and risk exposure.

Implications for Monetary Policy and Future Issuances

Yield compression may influence the Bank of Ghana’s policy stance, as lower short‑term rates reduce borrowing costs for the government and private sector. However, persistent oversubscription could signal an emerging reliance on market financing, prompting policymakers to monitor debt sustainability.

The Treasury’s willingness to exceed targets suggests confidence in market depth, yet future auctions will need to balance demand with fiscal objectives to avoid excessive yield volatility.

Looking Ahead

Projected liquidity improvements and continued investor confidence are expected to keep T‑bill demand robust in the coming weeks. Anticipated issuance volumes will likely align with the Treasury’s refinancing schedule, while yield trajectories remain subject to market sentiment and macroeconomic developments.
