Ghana's latest Treasury bill auction secured GHS 4.2 billion, falling short of the government’s GHS 5.27 billion target. This shortfall represents a 20.24 percent drop in aggregate bids, indicating weaker investor participation. The decreased demand follows a two-week period of oversubscription, highlighting growing caution among market participants.
This reduced investor interest emerged despite abundant liquidity within the banking system. Yields on government securities rose, with the 364-day Treasury bill increasing by 38 basis points to 11.36 percent. The 91-day and 182-day instruments also saw yield increases of 27 basis points and five basis points, respectively. This adjustment reflects investors demanding higher compensation for holding government securities.
These developments unfold within a broader context of rising inflation and persistent foreign exchange (FX) pressures in Ghana. Headline consumer inflation increased for the second consecutive month in May, reaching 3.7 percent year-on-year. This upward trend in inflation, combined with FX demand, adds complexity to an otherwise improving macroeconomic environment. The Bank of Ghana's efforts to absorb excess liquidity through open market operations (OMO) have also played a role.
Constant Capital noted that the softer auction demand reflects liquidity absorbed through earlier issuances and increasing investor caution. The firm stated, “The coexistence of substantial excess liquidity and softer Treasury bill demand suggests investors are becoming more selective rather than withdrawing from the market altogether.” This indicates a repricing of risk rather than a deterioration in market liquidity, with investors seeking better returns.
The current situation implies a challenging calibration for the government. It needs to attract stronger demand for its bonds without significantly increasing borrowing costs. Decision-makers and markets will watch to see if higher rates successfully draw in more investors. The government's current improved funding position allows for more flexibility, but the rising yields suggest continued vigilance is necessary.
Data from Black Star Analytics further reveals the scale of the Bank of Ghana’s interventions. In May 2026, the central bank absorbed approximately GHS 168.9 billion through OMO. This amount was more than double the average monthly OMO absorption of GHS 81.6 billion between May 2025 and May 2026. This extensive absorption highlights the persistence of excess liquidity in the banking sector.
The amount absorbed through OMO in May was notably over eight times the GHS 20.4 billion accepted at Treasury bill auctions during the same period. This divergence between liquidity conditions and government borrowing needs has become more apparent. Treasury bill acceptance volumes declined to GHS 20.4 billion in May, a significant drop from GHS 48.5 billion in January.
Despite this, Treasury bill maturities fell to GHS 16.9 billion, resulting in a net financing surplus of approximately GHS 3.5 billion for the government during May. This improved funding position suggests less immediate refinancing pressure. However, caution is also evident in secondary markets, with Treasury bill turnover dropping to GHS 11.6 billion in May from GHS 19.4 billion in April. Bond market activity also moderated, with turnover easing to GHS 10.91 billion from GHS 12.01 billion, reflecting a slowdown in trading activity.
