- Bank of Ghana Reduces Short-Term Liquidity Withdrawal to GH¢4.36 billion
The Bank of Ghana sold GH¢4.36 billion in 14-day bills at its October 14, 2026 tender, marking a sharp reduction in short-term liquidity absorption after the central bank issued GH¢13.83 billion through the same instrument only two days earlier.
Results published by the Bank showed that the October 14 sale carried a weighted average discount rate of 10.45 percent and an equivalent interest rate of 10.49 percent. All successful bids were allotted within a discount-rate range of 10.40 percent to 10.46 percent.
The amount sold declined by GH¢9.47 billion, or 68.5 percent, from the October 12 tender. The reduction was equally significant when compared with the GH¢9.01 billion issued on October 7, representing a fall of 51.6 percent.
Although the latest auction was smaller, pricing remained stable. The weighted average interest rate eased from 10.50 percent on October 12 to 10.49 percent, a decline of less than one basis point. The weighted discount rate similarly moved from 10.46 percent to 10.45 percent.
The combination of sharply lower issuance and almost unchanged pricing suggests that the adjustment was primarily about the quantity of liquidity the Bank wanted to absorb, rather than a deliberate attempt to reset short-term money-market rates.
Bank of Ghana bills are monetary-policy instruments issued by the central bank to withdraw excess liquidity from the banking system. They differ from Treasury bills, which are issued by the government to meet fiscal and cash-management requirements.
When the central bank sells its own bills, participating financial institutions exchange cash reserves for interest-bearing securities. This reduces available liquidity and can limit the amount of excess money circulating through the banking system, foreign-exchange market and other financial assets.
The October 14 result must therefore not be interpreted as GH¢4.36 billion in fresh government borrowing. It instead reflects the central bank’s assessment of liquidity conditions and the volume it considered necessary to sterilise for the instrument’s 14-day tenor.
Recent tender results reveal how actively that assessment has shifted. The Bank sold GH¢10.52 billion on October 5, GH¢9.01 billion on October 7 and GH¢13.83 billion on October 12 before reducing the October 14 issuance to GH¢4.36 billion.
Across those four October tenders, total sales reached GH¢37.72 billion, producing an average of GH¢9.43 billion per operation. The latest sale was about 53.7 percent below that average, reinforcing the view that the Bank required a materially smaller absorption than during the preceding operations.
The figures, however, do not disclose the total value of bids submitted, the number of participating institutions or whether any offers were rejected. It is consequently impossible to calculate an auction coverage ratio or determine conclusively whether the lower amount reflected weaker demand, a reduced offer by the Bank, or both.
That distinction is important. A decline in bills sold could indicate that banks had less surplus cash to place with the central bank. But it could also mean that the Bank deliberately accepted a smaller volume because earlier auctions had already removed enough liquidity from the system.
The October 12 sale was unusually large relative to the surrounding tenders. Its GH¢13.83 billion issuance was 53.5 percent above the October 7 result and approached the GH¢14.72 billion sold on September 28. Two days later, the Bank’s smaller operation may therefore represent a normalisation after substantial earlier absorption.
Pricing offers another clue. At the October 12 tender, bids were tightly grouped between discount rates of 10.4577 percent and 10.4578 percent. On October 14, the range widened materially, beginning at 10.40 percent while retaining the same upper boundary of 10.46 percent.
Some institutions were thus willing to accept slightly lower returns. The weighted rate’s limited decline indicates that a considerable share of the accepted volume was nevertheless priced close to the top of the range.
For banks, the instrument offers a short-duration destination for excess funds with minimal exposure to interest-rate volatility. Its two-week maturity allows institutions to earn a return while preserving flexibility over their liquidity positions.
For the Bank of Ghana, the bills provide a mechanism for keeping short-term liquidity consistent with the monetary-policy stance. Excess banking-system liquidity can weaken the transmission of the policy rate, place downward pressure on overnight market rates and potentially increase demand for foreign currency.
Absorbing liquidity can therefore help preserve monetary control, particularly when the central bank is seeking to consolidate gains in inflation and exchange-rate stability. Yet sterilisation is not without cost. The Bank must pay interest on the bills, meaning repeated large-scale operations create expenses on its own balance sheet.
The policy challenge lies in removing enough liquidity to support monetary and currency stability without unnecessarily restricting credit or accumulating excessive sterilisation costs. The October pattern demonstrates the precision this balancing exercise requires: auction volumes changed substantially while the price of short-term liquidity barely moved.
The stable yield also provides a useful signal for the broader money market. Despite the large swings in issuance, the weighted interest rate across the October 5, October 7, October 12 and October 14 tenders remained within an exceptionally narrow range of 10.49 percent to 10.50 percent.
Such stability may help anchor expectations among banks and institutional investors. It suggests that the central bank is adjusting liquidity mainly through volumes while keeping the return on its 14-day instrument close to 10.5 percent.
Still, one smaller auction does not establish a lasting change in liquidity conditions. A sustained decline in subsequent bill sales would provide stronger evidence that surplus funds in the banking system are easing. A renewed increase would indicate that liquidity pressures remain fluid and require continuing intervention.
Market participants should consequently watch the size and pricing of the next operation, alongside interbank rates, foreign-exchange demand and credit conditions. Those indicators will help determine whether the October 14 reduction was temporary or the beginning of a lower sterilisation cycle.
For now, the clearest conclusion is that the Bank of Ghana substantially reduced the scale of its liquidity withdrawal without materially changing its short-term rate signal. That is a measured adjustment, but its significance will ultimately be determined by what follows.
