The Bank of Ghana bills market recorded another sizeable transaction on September 9, 2026, as the central bank sold GH¢11.85 billion in securities with a maturity period of just two weeks.
Official results from Tender 878 show that GH¢11,852.73 million was sold through a single 14 day instrument identified by the International Securities Identification Number GHCBAGH01413.
The scale of the sale may look like another round of government borrowing. It is not. These bills form part of the central bank’s effort to manage the amount of money circulating within Ghana’s banking system.
Bids cluster within narrow range
Investors submitted annual discount rates ranging from 10.40% to 10.46%. The Bank of Ghana accepted bids across that entire range.
The weighted average discount rate settled at 10.46%, while the equivalent weighted average interest rate was 10.50%.
That distinction matters. The bills are sold below their face value and repaid at the full amount when they mature. An investor’s return comes from the difference between the purchase price and the repayment value.
The interest rate translates that return into an annualised measure that can be compared with yields on other securities.
The close pricing suggests bidders valued the two week instrument within a tight range. It does not, however, reveal how strong total demand was.
Although the notice records the “TOTAL AMOUNT SOLD”, it does not disclose the overall value of bids submitted. There is therefore no basis for calculating whether the auction was oversubscribed or undersubscribed.
Not fresh government borrowing
Bank of Ghana bills serve a different purpose from Treasury bills and government bonds.
Treasury securities are issued to finance public expenditure or refinance existing state debt. Central bank bills are monetary instruments used mainly to absorb liquidity from banks and other eligible financial institutions.
Through the September 9 operation, participating institutions exchanged available cash for securities issued by the central bank. That temporarily removes some liquidity from immediate circulation.
The money returns to investors when the bills mature after 14 days, together with the applicable return. Unless another operation follows, the withdrawal is not permanent.
Gross amount tells only part of story
The GH¢11.85 billion headline provides a snapshot of the Bank of Ghana’s activity, but it does not show the net effect on financial system liquidity.
Bills from previous auctions may be maturing at the same time, returning funds to investors. Government payments, tax receipts, foreign exchange transactions and other flows can also add or remove money from the banking system.
A proper assessment would therefore compare new issuance with maturing securities and the central bank’s other operations.
Short dated bills give policymakers room to respond quickly as conditions change. If banks hold more liquidity than the central bank considers appropriate, the securities can help limit excess funds from feeding into foreign exchange demand, asset prices or rapid credit expansion.
There is a cost. The Bank of Ghana must pay investors for holding the bills, meaning repeated large operations can create a notable interest expense.
Tender 878 shows that liquidity management remains active. What it does not show, on its own, is whether monetary conditions are becoming tighter or whether the September sale represents an unusually large intervention.
The more revealing figure will be the banking system’s net liquidity position once maturities and other central bank transactions are counted.
