T-Bill auction oversubscribed by 30% as interest rates decline further, buoying government’s borrowing plans

The government’s treasury bill auction for the week ending July 24 recorded a robust 30.3% oversubscription, surpassing its target by a significant margin, even as interest rates across all tenors continued their downward trajectory. The strong demand, which coincided with the presentation of the Mid-Year Budget Review by the Finance Minister on Thursday, signals sustained investor confidence in short-term government paper despite persistent concerns over Ghana’s fiscal position.

According to auction results released by the Bank of Ghana, the government received total bids of GH¢12.37 billion against a target of GH¢9.49 billion, accepting GH¢11.54 billion—an acceptance rate of 93.3%. The oversubscription marks the fourth consecutive week that the government has exceeded its issuance target, a trend that analysts attribute to excess liquidity in the banking system and a dearth of alternative high-yield investment instruments.

Yield Curve Trends

The decline in interest rates, which has been steady since the beginning of the second quarter, continued across all three tenors:

· 91-day bill: Yield fell by 11 basis points to 5.76%, down from 5.87% the previous week. This represents the lowest rate on the shortest-dated instrument since early 2024.
· 182-day bill: Yield dropped 10 basis points to 7.68%, from 7.78% a week earlier.
· 364-day bill: Yield eased by 3 basis points to 12.96%, compared to 12.99% previously.

The 364-day bill remained the most sought-after instrument, accounting for 65.5% of total bids—GH¢8.11 billion tendered against GH¢7.82 billion accepted. This suggests that investors are increasingly willing to lock in funds for longer periods, betting on continued stability in short-term rates and a gradual easing of monetary policy.

Mid-Year Budget Context

The auction’s timing was notable: Finance Minister Dr. Cassiel Ato Forson delivered the Mid-Year Budget Review on Thursday, outlining the government’s revised expenditure and revenue targets for 2026. In his address, he reaffirmed the administration’s commitment to fiscal consolidation, lower borrowing costs, and a reduction in the domestic debt stock. The market’s enthusiastic response to the T-bill auction—coming just hours after the budget speech—appears to validate investor optimism that the government will stay the course on its fiscal targets.

However, the oversubscription also raises questions about the cost of borrowing. While lower yields reduce the government’s debt service burden, they also indicate that the central bank’s policy rate—currently at 18%—may be out of step with market realities. Some economists argue that the gap between the policy rate and T-bill yields creates an arbitrage opportunity that could fuel speculative trading rather than productive investment.

What the Data Shows

The breakdown of the auction reveals a clear preference for longer maturities:

Security Bids Tendered Bids Accepted Yield (Week) Previous Yield
91-day GH¢2.95bn GH¢2.60bn 5.76% 5.87%
182-day GH¢1.30bn GH¢1.12bn 7.68% 7.78%
364-day GH¢8.11bn GH¢7.82bn 12.96% 12.99%
Total GH¢12.37bn GH¢11.54bn — —

The government accepted fewer bids than tendered—a deliberate strategy to avoid absorbing excess liquidity at rates that might prove unsustainable later. By rejecting about GH¢830 million in bids, the Bank of Ghana effectively signalled that it is not willing to pay premium yields, thereby maintaining downward pressure on rates.

Economic Implications

The continued decline in T-bill yields has several implications for the broader economy:

· Lower debt service costs: With interest rates trending down, the government will spend less on servicing its short-term domestic debt, freeing up fiscal space for infrastructure and social spending.
· Crowding-out effect diminished: Lower yields on government securities may encourage commercial banks to channel more credit to the private sector, rather than parking funds in risk-free T-bills. This could spur investment and job creation.
· Inflation outlook: Falling yields often signal market expectations of lower inflation ahead. However, the central bank must remain vigilant, as liquidity injections from T-bill maturities could re-ignite price pressures if not carefully managed.

Market Reactions and Analyst Views

Financial analysts have welcomed the trend but caution against complacency. Dr. John Kwakye, a senior economist, noted in a social media post: “The oversubscription is good news for the government, but we must ask why banks are so eager to lend to the state. It reflects a lack of attractive private-sector lending opportunities, not just fiscal confidence. The real test will be whether these lower rates translate into cheaper loans for businesses.”

Meanwhile, the Ghana Stock Exchange (GSE) saw marginal gains in bond trading, as secondary market yields followed the primary auction trends. Some institutional investors, including pension funds, have reportedly increased their allocation to short-term instruments, seeking safety amid lingering uncertainties about the global economic environment.

Outlook for the Coming Weeks

Market participants are now looking ahead to the next auction, scheduled for July 31, which will coincide with the release of the June inflation data. If inflation continues to moderate—it currently stands at 21.7%—analysts expect further declines in yields, potentially pushing the 91-day rate below 5.5% in the near term.

However, the government’s total domestic borrowing requirement for 2026 remains substantial, and the ministry has signalled that it may increase its issuance of longer-dated bonds in the second half of the year to extend the maturity profile and reduce rollover risks. The sustained demand for T-bills, even at lower rates, provides a strong foundation for such a transition.

As Ghana navigates its post-IMF programme recovery, the T-bill market remains a key barometer of investor sentiment. For now, the signals are unmistakably positive—demand is high, rates are falling, and the government is consistently raising more than it seeks. Whether this momentum can be sustained through the election cycle and into 2027 will depend on the credibility of the government’s fiscal vows and the resilience of the banking sector.
