- BoG Absorbs GH¢7.70bn Through 14-Day Securities at 10.50%
The Bank of Ghana has absorbed GH¢7.70 billion from the financial system through the sale of 14-day central-bank bills, maintaining its use of short-dated securities to manage liquidity while pricing the instruments at a weighted average annualised interest rate of about 10.50%.
Results of Tender 879, held on September 16, show that the central bank sold GH¢7,702.71 million in 14-day Bank of Ghana bills. The securities were issued under ISIN GHCBAGH01439.
The weighted average discount rate settled at 10.45% per annum, translating into a weighted average interest rate of 10.4962%, effectively 10.50% when rounded to two decimal places.
Banks submitted bids at discount rates ranging from 10.4000% to 10.4578%, with the entire quoted range allotted in full. The corresponding annualised interest rates ranged from approximately 10.44% to 10.50%.
The operation represents another sizeable deployment of short-term central-bank securities as the Bank of Ghana seeks to regulate liquidity conditions in the banking system.
BoG bills differ fundamentally from Government of Ghana Treasury bills.
Treasury bills are government debt instruments used as part of the state’s financing programme, while Bank of Ghana bills are issued by the central bank principally as monetary-policy and liquidity-management instruments. When banks purchase the securities, liquidity is temporarily transferred from the banking system to the central bank for the duration of the instrument.
The GH¢7.70 billion transaction therefore should not be interpreted as GH¢7.70 billion in new fiscal borrowing by government.
Instead, it reflects the central bank’s management of the amount of money available within the banking system, an important part of transmitting monetary policy to short-term market rates and ultimately to broader financial conditions.
The size of the operation is significant. At more than GH¢7.7 billion, the tender temporarily places a substantial amount of banking-system liquidity into central-bank securities for 14 days. Once the bills mature, the principal and applicable return are released unless the liquidity is subsequently rolled into new securities or addressed through other monetary operations.
Such liquidity management matters because excess funds in the banking system can place downward pressure on very short-term interest rates and, depending on wider economic conditions, potentially influence credit expansion, foreign-exchange demand and broader monetary conditions.
Conversely, absorbing too much liquidity for prolonged periods can affect the amount of funds available to financial institutions for lending and other market activities.
The central bank must therefore continuously balance liquidity absorption against the need for an efficiently functioning financial system.
Pricing is another important element of the September 16 operation. The narrow range between the lowest and highest bid rates, 10.40% and 10.46% on a discount basis, suggests bidding was concentrated around a relatively tight pricing corridor.
The maximum corresponding interest rate was 10.50%, while the weighted average interest rate finished slightly lower at 10.4962%.
That means the bulk of accepted funds were priced very close to the upper end of the quoted interest-rate range.
For participating banks, the securities provide a short-duration instrument through which excess cash can be placed with the central bank while earning a return.
For the Bank of Ghana, they provide a mechanism for influencing the quantity and price of short-term liquidity without altering the policy rate each time money-market conditions change.
The 14-day maturity also gives the central bank considerable flexibility. Unlike longer-term securities, two-week bills allow liquidity conditions to be reassessed frequently. If excess liquidity persists, the Bank can conduct further operations. If conditions tighten, maturing securities can return funds to the banking system or the scale of subsequent absorption can be adjusted.
The September 16 notice, however, does not state the total value of bids submitted by market participants, nor does it disclose a predetermined target for the operation.
It would therefore be inappropriate to characterise the tender as oversubscribed or undersubscribed based solely on the published results.
The document confirms only the range of bids, rates allotted, weighted average pricing and the final amount sold.
That distinction is important because the amount ultimately sold does not by itself indicate whether banks sought to place substantially more funds with the central bank or whether the Bank deliberately capped the volume accepted.
The transaction also comes as market participants continue to watch the relationship between monetary-policy rates, Treasury yields and central-bank liquidity operations.
Short-term rates influence banks’ opportunity cost of funds and can affect decisions over whether liquidity is deployed into government securities, central-bank instruments, interbank lending or private-sector credit.
A 10.50% annualised return on a 14-day central-bank instrument consequently provides an important reference point within the very short end of Ghana’s interest-rate structure.
But the economic significance of the tender extends beyond the yield itself.
The GH¢7.70 billion operation demonstrates how actively the central bank is using its balance sheet to influence liquidity between formal Monetary Policy Committee decisions.
Interest-rate policy sets the broad monetary stance, while open-market and short-term liquidity operations help ensure that actual conditions in the financial system remain consistent with that stance.
For banks, the bills offer safety, short maturity and predictable returns. For the central bank, they provide a flexible mechanism for temporarily removing surplus liquidity and influencing money-market conditions.
Tender 879 therefore represents more than another securities auction. By absorbing GH¢7.70 billion for 14 days at a weighted annualised interest rate of 10.4962%, the Bank of Ghana is continuing to use short-term securities as a key operational tool for managing liquidity with the effectiveness of that approach ultimately depending on how closely money-market conditions remain aligned with the broader direction of monetary policy.
