The Bank of Ghana has withdrawn GH¢8.48 billion from the banking system through its latest 14-day bill auction, continuing its liquidity management operations even as the volume of funds absorbed fell sharply compared with previous auctions.
Results from Tender 873, conducted on Wednesday, August 5, 2026, show the central bank allotted GH¢8,478.44 million through its 14-day Bank of Ghana bill.
Although the amount absorbed was considerably lower than in recent weeks, pricing barely moved, with the weighted average interest rate settling at 10.50 percent.
That consistency has become a feature of the market. The quantity changes. The rate hardly does.
Liquidity withdrawal slows
Commercial banks submitted bids at annualised discount rates ranging between 10.40 percent and 10.46 percent, all of which were accepted. The weighted average discount rate closed at 10.46 percent, translating into a weighted average interest rate of 10.50 percent.
The latest operation represents a marked slowdown in the scale of liquidity absorption.
At Tender 872 on July 27, the central bank withdrew GH¢16.57 billion, almost twice the amount sold this week. The latest figure is 48.83 percent lower than that auction.
It also trails the GH¢9.25 billion absorbed on July 22, the GH¢11.68 billion sold on July 15 and the GH¢14.42 billion withdrawn earlier in July.
The pattern suggests that while the Bank remains active in managing money market liquidity, the immediate need to sterilise excess cash may have eased.
Why the auction matters
Unlike Treasury bills, Bank of Ghana bills are not issued to finance government spending.
Instead, they serve as monetary policy instruments designed to remove excess liquidity from the financial system. By temporarily locking funds away for 14 days, the central bank helps stabilise short-term interest rates while limiting the risk that surplus liquidity fuels inflation or places additional pressure on the foreign exchange market.
This week's smaller auction could point to several developments. Banks may simply be holding less excess cash after earlier liquidity withdrawals.
Government transactions, maturing securities or routine money market movements may also have altered funding conditions.
The auction results do not reveal which factor carried the greatest weight, and the Bank of Ghana offered no explanation for the reduced volume.
Stable rates despite changing volumes
What stands out is the remarkable stability in pricing.
Whether the Bank absorbed GH¢16.57 billion, GH¢11.68 billion or GH¢8.48 billion, the weighted average interest rate has consistently remained around 10.50 percent.
That stability indicates the central bank has been successful in anchoring very short-term money market rates despite significant swings in liquidity volumes.
Earlier in the year, however, borrowing costs were noticeably higher.
On March 16, the Bank sold GH¢19.44 billion in 14-day bills at a weighted average interest rate of 11.99 percent. By early May, the rate had eased to approximately 10.50 percent, where it has remained through successive auctions.
The trend reflects a moderation in short-term sterilisation rates while the central bank continues to actively absorb liquidity.
Market watches the next move
The latest auction also highlights a broader issue facing monetary authorities.
Large-scale liquidity sterilisation carries a cost because the Bank of Ghana pays interest on the bills it issues. The repeated use of these operations has therefore attracted attention amid discussions about the central bank's balance sheet and the financial implications of open market operations.
For banks and institutional investors, the latest auction still provides a relatively low-risk, short-duration investment offering annualised returns of about 10.50 percent over just two weeks.
For economists, the more revealing figure may not be the interest rate at all.
The Bank of Ghana is still withdrawing liquidity from the financial system, but it is doing so on a noticeably smaller scale than during several auctions in July. Whether that signals a sustained easing in excess liquidity or merely reflects temporary shifts in banking sector cash positions will become clearer in the coming weeks.
For now, one message is unmistakable. The volumes are moving, but the price of short-term liquidity remains firmly anchored.
