Ghana’s Money Market: What It Is and Why It Matters

The money market refers to the segment of the financial system dedicated to short-term borrowing, lending, and investing — typically involving instruments with maturities of one year or less. In Ghana, the money market is overseen by the Bank of Ghana (BoG) and the Securities and Exchange Commission (SEC), which together regulate the institutions and instruments available to investors.

For small businesses, the money market is particularly relevant because it offers relatively low-risk, accessible entry points into investment — without requiring large minimum amounts or sophisticated financial knowledge. The key options available to Ghanaian businesses include government Treasury Bills, bank fixed deposits, and mobile-money-linked savings products.

Option 1: Government Treasury Bills — Safe, High-Yielding, and Government-Backed

Government of Ghana Treasury Bills are short-term debt instruments issued weekly by the government through the Bank of Ghana. They are available in three tenors: 91 days, 182 days, and 364 days — and are widely regarded as one of the safest investments available in Ghana, backed by the Government of Ghana’s full credit.

Current Treasury Bill rates are highly attractive. The 91-day bill is currently yielding in the range of 24–26% per annum, with 182-day and 364-day instruments offering even higher rates of approximately 27–30% per annum. These rates significantly outperform standard bank savings accounts and make Treasury Bills one of the most compelling short-term investment options for businesses with surplus cash they can set aside for 91 days or more.

Businesses can access Treasury Bills through licensed Primary Dealers, including GCB Bank, Ecobank Ghana, Databank, and IC Securities. Minimum investment amounts vary by institution but can be as low as GHS 100, making this genuinely accessible for businesses of all sizes.

Option 2: Fixed Deposits — Predictable Returns Through Your Bank

Fixed deposits are interest-bearing products offered by licensed banks and financial institutions, typically returning between 15% and 20% per annum depending on the institution, tenure, and amount deposited. They offer predictability — a fixed rate for a defined period — which suits businesses that want certainty over their returns without engaging with the government securities market directly.

Institutions offering competitive fixed deposit products include Fidelity Bank Ghana, Absa Bank Ghana, Standard Chartered Ghana, and Cal Bank. All are regulated by the Bank of Ghana — always verify an institution’s licence before investing.

Option 3: MTN Yello Save — Mobile-First Savings for the Modern Business Owner

For small businesses and sole traders who value flexibility and accessibility, MTN Ghana’s Yello Save — a savings product offered in partnership with Fidelity Bank Ghana — provides a straightforward entry point into interest-bearing savings without visiting a branch.

Yello Save currently offers up to 8% per annum on saved balances, with interest accruing monthly and accessible via the MTN MoMo platform by dialling *170#. There are no account fees and no minimum balance requirement. For businesses already receiving payments via MTN Mobile Money — a channel supported through Prompt Integrated’s Payswitch integration — Yello Save provides a natural destination for surplus MoMo funds to earn returns rather than sitting idle.

The Ghana Stock Exchange: Africa’s Standout Equity Market

For businesses with a longer investment horizon and a slightly higher risk appetite, the Ghana Stock Exchange (GSE) presents a compelling opportunity. The GSE Composite Index surged by 79.40% in 2025 — the highest calendar year return since 2004 — with the GSE Financial Index returning an even more impressive 95.19%. Looking ahead, the GSE Composite Index is projected to deliver approximately 81% returns in 2026, supported by commodity-linked equities and improving corporate profitability, according to the Minerals Income Investment Fund outlook.

These are exceptional figures — and it is important to note that equity markets experience volatility, and past performance does not guarantee future returns. For long-term planning, using a conservative historical average is more prudent. Over a rolling 20-year period, the GSE has historically delivered average annual returns of approximately 15% per annum in cedi terms — a figure we use as the basis for the compound interest example below.

Ghanaian businesses can access GSE-listed equities through licensed stockbrokers regulated by the Securities and Exchange Commission (SEC). Firms such as Databank, IC Securities, and CDH Securities offer investment advisory and execution services.

The Power of Compound Interest: GHS 20,000 Invested for 20 Years

To understand why investing surplus cash matters, consider what happens to GHS 20,000 invested at a conservative long-term average return of 15% per annum — reflective of historical GSE performance — left to compound over 20 years.

The compound interest formula is: A = P × (1 + r)ⁿ

Where A is the final amount, P is the principal (GHS 20,000), r is the annual rate (15% = 0.15), and n is the number of years (20).

A = 20,000 × (1.15)²⁰ = 20,000 × 16.3665 = GHS 327,330

An initial investment of GHS 20,000 grows to approximately GHS 327,330 over 20 years at 15% per annum — a gain of over GHS 307,000 from compound interest alone, without adding a single additional cedi. The visual below illustrates how this growth accelerates over time.

Note: This example uses a conservative 15% p.a. based on long-term GSE historical averages. Actual returns will vary. This is illustrative only and not financial advice.
