- BoG Withdraws GH¢10.76 bn as Demand for 14-Day Bills More than Doubles
The Bank of Ghana has sold GH¢10.76 billion in 14-day central bank bills, more than doubling the amount placed at its preceding auction while keeping the annualised interest rate close to 10.50 per cent.
Results of Tender 884, held on October 19, show that the central bank sold GH¢10,757.15 million of the short-dated securities. The operation represents a sharp increase from the GH¢4,362.29 million sold under Tender 883 on October 14.
The latest sale was GH¢6,394.86 million larger than the preceding operation, equivalent to an increase of approximately 146.6 per cent.
Pricing, however, barely moved. Investors submitted discount rates ranging from 10.40 per cent to 10.46 per cent, and the Bank allotted that entire range in full. Corresponding interest rates ranged from 10.44 per cent to 10.50 per cent.
The weighted average discount rate settled at 10.45 per cent, while the weighted average interest rate was 10.50 per cent. At the October 14 auction, the corresponding averages were 10.45 per cent and 10.49 per cent. The latest interest rate therefore rose by only 0.43 basis points despite the significant increase in the amount sold.
That combination considerably greater volume with almost unchanged pricing is the most revealing feature of the results. It suggests that the additional liquidity absorbed by the Bank did not require a meaningful yield concession. Institutions remained willing to place funds at rates clustered tightly around the established 10.50 per cent ceiling.
The spread was narrow. The difference between the lowest and highest submitted discount rates was 5.78 basis points, indicating limited disagreement among institutions about the price of two-week liquidity. The Bank accepted the full quoted range rather than rejecting the more expensive end, although the notice does not disclose individual bid volumes at each rate.
Bank of Ghana bills are different from Treasury bills issued on behalf of the government. Treasury securities primarily finance public expenditure and refinance government obligations. Central bank bills are monetary-policy instruments used to absorb liquidity from the financial system and influence short-term market conditions.
When banks hold more cash than the central bank considers consistent with its monetary objectives, the Bank can sell its own securities and temporarily lock that liquidity away. The funds return when the bills mature, unless they are renewed through another operation. The 14-day tenor gives the Bank flexibility to adjust quickly as liquidity conditions change.
The GH¢10.76 billion sale is therefore a gross liquidity withdrawal, not necessarily the net amount removed from the system. Establishing the net effect requires information on bills maturing around the same date, fresh liquidity entering through government expenditure, foreign-exchange transactions and other central bank operations. A large auction can primarily refinance maturing paper rather than represent an equally large tightening impulse.
This distinction matters because the headline amount could otherwise be mistaken for government borrowing or a permanent reduction in money supply. Neither conclusion follows automatically. The instrument has a two-week life and forms part of a rolling liquidity-management framework in which the Bank repeatedly withdraws and releases funds as securities are issued and redeemed.
The tender result also has limitations for analysing investor demand. The notice reports the amount sold and the range of rates submitted and allotted, but it does not state an auction target, the total value of bids received or the number of participating institutions. It is therefore impossible to calculate an oversubscription ratio, rejection rate or bid-to-cover measure.
The amount sold nevertheless provides a useful indicator of available short-term funds, especially when compared with the previous auction. The jump from GH¢4.36 billion to GH¢10.76 billion may reflect larger surplus balances within the banking system, greater rollover requirements or a deliberate decision by the central bank to absorb more liquidity. The published figures alone cannot establish which explanation dominates.
For participating banks, the bill offers a low-duration instrument for placing temporary surplus funds. Its maturity limits exposure to changes in interest rates and allows institutions to recover cash relatively quickly. The annualised interest rate of 10.4962 per cent does not mean investors earn that return over 14 days; the actual holding-period return is only a fraction of the quoted yearly rate.
The persistent gap between the bill’s yield and the 14 per cent monetary-policy rate is also noteworthy. The policy rate signals the broad stance of monetary policy, while auction pricing reflects immediate liquidity conditions and the characteristics of the instrument. Strong demand for short-dated central bank paper can keep its yield below the benchmark rate, particularly where institutions value safety and liquidity.
Yet substantial placements in central bank securities raise a broader policy question. Liquidity absorption can support price and exchange-rate stability by limiting excess cash that might intensify demand for goods, credit or foreign currency. But if banks consistently prefer risk-free short-term instruments to lending to businesses, monetary stability may coexist with weak private-sector credit growth.
That does not mean the Bank should leave excess liquidity unaddressed. It means policymakers must watch both sides of the transmission mechanism: whether liquidity operations stabilise markets and whether financing continues to reach productive firms. The composition of bank assets, credit conditions and lending rates will determine whether short-term sterilisation complements economic recovery or inadvertently reinforces cautious lending.
Market attention will now turn to the next auction and the maturity of the GH¢10.76 billion placement. Another large operation would indicate that elevated liquidity absorption is continuing. A significantly smaller sale could allow funds to return to the banking system, depending on other flows.
Tender 884 ultimately shows a central bank able to absorb a much larger volume without materially raising its cost. That is a favourable immediate signal for liquidity management. The deeper test is whether the Bank can preserve monetary stability while ensuring that the financial system does not become more comfortable financing two-week paper than Ghana’s longer-term productive economy.
