a) The three main classifications of money are:

• Narrow money (M1): This includes currency in circulation (notes and coins) and demand deposits held in commercial banks, such as current accounts at GCB Bank in Ghana, which are highly liquid and used for immediate transactions, aligning with BoG’s monitoring for monetary policy under the Bank of Ghana Act, 2002 (Act 612).
• Broad money (M2): This encompasses M1 plus time deposits, savings deposits, and other near-money assets like fixed deposits at Ecobank Ghana, reflecting a broader measure of liquidity that influences inflation and economic stability, as tracked in BoG’s monthly economic data reports.
• Broadest money (M3): This includes M2 plus large institutional deposits and money market funds, often used for comprehensive analysis in Ghana’s financial sector, helping assess overall credit availability amid events like the 2022-2024 DDEP, where BoG adjusted policies to manage liquidity.

bi) Money supply refers to the total amount of monetary assets available in an economy at a specific time, including currency, deposits, and other liquid instruments, regulated by the Bank of Ghana through tools like reserve requirements under the Liquidity Risk Management Guidelines to control inflation and support growth.

          bii) Two main functions of money are:

• Medium of exchange: Money facilitates transactions by eliminating the inefficiencies of barter, as seen in Ghana where cedi notes and mobile money via MTN Momo (regulated under Act 987) enable seamless payments, enhancing trade and banking operations at institutions like Stanbic Bank Ghana.
• Store of value: Money allows individuals and businesses to save wealth for future use, though inflation erodes this, prompting BoG’s inflation-targeting framework (aiming for 8% ±2%) to preserve value, as demonstrated post-2017 banking cleanup when stable deposits supported economic recovery.

              c) Three main advantages gained in the use of open market operations (OMO) are:

• Flexibility in monetary policy implementation: The BoG can buy or sell government securities to adjust liquidity quickly without disrupting markets, as used during the 2023 post-DDEP recovery to inject funds and stabilize banks like Access Bank Ghana, complying with Basel III liquidity standards.
• Market-driven interest rate influence: OMOs allow indirect control of short-term rates through supply and demand, helping manage borrowing costs for commercial banks under the Capital Requirements Directive, reducing risks from high rates seen in the 2019 cleanup where insolvent banks like UT Bank failed due to liquidity mismatches.
• Transparency and predictability: By announcing OMO auctions, BoG builds market confidence and signals policy intentions, aligning with the Corporate Governance Directive 2018 for ethical practices, enabling banks to plan asset structures effectively in a digital era with fintech integrations.

  d) If the interest rate rises, the current value (present value) of a given sum of money decreases, as higher rates discount future cash flows more heavily; for instance, in Ghana, a rise in BoG’s policy rate from 13.5% in 2021 to 30% in 2023 reduced the present value of fixed deposits, impacting investment decisions and bank profitability under prudential controls.
