A money market fund (MMF) pools capital from multiple investors to buy short-term, high-quality debt instruments — Treasury bills, commercial paper, certificates of deposit, and repurchase agreements.
The goal is to earn a return above a savings account while keeping your money accessible and your principal largely intact.
MMFs are not savings accounts. They are investment products. That distinction matters because your returns can fluctuate with interest rates, and your capital is not government-insured the way a bank deposit is. That said, they remain one of the most widely used short-term instruments globally, from retail investors in Nairobi and Accra to institutional treasuries in New York.

How Money Market Funds Work
Fund managers pool incoming investments and deploy them across a basket of short-duration, high-credit-quality instruments. Investors receive units or shares in the fund, and their returns reflect the interest earned on the underlying holdings minus management fees.
Because the instruments held — T-bills, commercial paper, bank-issued CDs — mature in days to months, the portfolio turns over frequently. This keeps both credit risk and interest rate risk low. In most jurisdictions, regulators impose strict limits on maturity, credit ratings, and portfolio concentration to prevent a fund from straying into riskier territory.
Returns are not guaranteed. They track the prevailing interest rate environment. When central banks cut rates, MMF yields fall. When rates are high, yields improve. This is why MMF performance is closely tied to monetary policy decisions.
Types of Money Market Funds
Money market funds are generally categorized based on their underlying assets:
Government/Treasury Funds invest primarily in sovereign debt instruments — Treasury bills and notes issued by the national government. These carry the lowest credit risk because the probability of a government defaulting on short-term domestic obligations is minimal. Returns tend to be slightly lower than other MMF types as a result.
Prime Funds go a step further by including corporate bonds, commercial paper, and certificates of deposit from highly rated banks and companies. The credit exposure is marginally higher, but so are potential returns.
Tax-Exempt Funds — common in the United States — invest in short-term municipal securities whose income is exempt from federal income tax. These are less common in African markets.
Foreign Currency Funds are increasingly available in African markets, particularly for US dollar-denominated instruments. These serve investors looking to hedge against local currency depreciation.
Money Market Funds vs. Money Market Accounts
These two products are frequently confused, but they are structurally different.
A money market fund is an investment product managed by an asset management firm. It is not bank-held, not FDIC-insured, and its returns vary with the market. You buy units in a pooled fund.
A money market account (MMA) — also called a Money Market Deposit Account (MMDA) — is a bank product. Banks offer MMAs as a hybrid between savings and checking accounts, typically paying higher interest than a standard savings account while offering limited transactional features like check-writing or a debit card. In most markets, MMAs are covered by deposit insurance up to the statutory limit.
The key differences come down to insurance, accessibility, and return profile. MMAs offer the security of deposit insurance and sometimes check-writing privileges, but their interest rates are set by the individual bank and tend to be lower than what a well-managed MMF delivers. MMFs offer higher potential returns and are actively managed, but carry no deposit guarantee and their yields shift with market conditions.
For short-term goals — emergency savings, school fees, a travel fund — either product can work. The practical choice usually comes down to whether you prioritize convenience and insurance (MMA) or yield and compounding (MMF).
Advantages of Money Market Funds
Low Risk. MMFs invest only in short-maturity, high-rated instruments. While not risk-free, the probability of significant loss is low under normal market conditions.
Liquidity. Most funds allow withdrawals within 24 to 48 hours of a redemption request. This makes them a practical parking spot for emergency funds or cash awaiting deployment.
Better Returns than Savings Accounts. In markets where savings account interest rates are suppressed, MMFs consistently offer higher yields. In Kenya, for example, the gap between a typical bank savings rate and a well-performing MMF net yield has at times exceeded several percentage points.
Low Entry Barrier. Retail MMFs across Africa and the US allow investors to start with small amounts. Some Kenyan funds accept initial investments as low as KES 1,000, while certain Ghanaian funds set minimums as low as GH¢50.
Diversification. Even a small investment is spread across multiple instruments, issuers, and maturities, reducing single-issuer risk.
Disadvantages of Money Market Funds
Modest Returns. The trade-off for low risk and high liquidity is that MMFs rarely deliver returns that significantly outpace inflation over the long term. They are designed for capital preservation, not wealth accumulation.
Interest Rate Sensitivity. When central banks enter a rate-cutting cycle, MMF yields fall. Investors who locked in expectations based on peak-rate performance will see their returns decline as the portfolio rolls into lower-yielding instruments.
No Deposit Insurance. Unlike bank savings accounts, MMFs are not backed by deposit guarantee schemes. In the event of a fund failure — rare but not impossible — investors could lose capital.
Fees Reduce Net Returns. Management fees are deducted before returns are distributed. A gross yield of 14% in Kenya with a 2% annual management fee and 15% withholding tax on interest income will yield something materially lower to the end investor. Always compare net-of-fee returns, not gross yields.
How to Invest in a Money Market Fund
The process is similar across most markets:
- Choose a licensed fund manager. Look for firms regulated by the relevant authority — the Capital Markets Authority (CMA) in Kenya, the Securities and Exchange Commission (SEC) in Ghana, and the SEC in the United States.
- Open an account. This typically requires a national ID or passport, tax identification number, and proof of residence. Many funds now allow fully digital onboarding.
- Fund your account. Transfer the minimum required amount. Some funds allow direct debit or mobile money in markets where that infrastructure exists.
- Monitor performance. Check net-of-fee returns, not just the fund's advertised rate. Review the fund's published fact sheets and compare against a market benchmark where available.
Who Should Invest in Money Market Funds?
MMFs are well-suited for investors who need a liquid, low-risk home for short-term capital. Specific use cases include:
- Emergency funds — money you may need quickly but want earning a return in the meantime
- Short-term savings goals — school fees, a property deposit, travel expenses within a 6-to-18-month horizon
- Cash management — businesses or institutions holding working capital between deployment cycles
- Conservative investors — those prioritising capital preservation over growth
MMFs are not suited for long-term wealth building. Over a 10- to 20-year horizon, equities and fixed-income instruments will almost always outperform. The value of an MMF is in what it does well: keeping your money safe, liquid, and working.
MMFs in Kenya, Ghana, and the United States: A Comparison
While money market funds share the same structural logic globally whereby the pool investment in short-term instruments, the markets in Kenya, Ghana, and the United States differ considerably in size, regulation, yields, and investor behaviour.
Regulation
In Kenya, MMFs are regulated by the Capital Markets Authority (CMA) under the Capital Markets Act. Funds must publish daily yields, submit regular filings, and operate under CMA-prescribed limits on portfolio composition and liquidity. A 15% withholding tax applies to interest income. As of 2026, new CMA rules are expected to come into force by December, tightening standards further.
In Ghana, MMFs operate under the oversight of the Securities and Exchange Commission (SEC) of Ghana. The SEC issued updated Securities Industry Financial Resources Guidelines in August 2025, extending liquidity monitoring obligations to all licensed market operators and increasing penalties for non-compliance. Ghanaian funds are also structured as unit trusts, similar to Kenya.
In the United States, MMFs are governed by SEC Rule 2a-7 under the Investment Company Act of 1940. Following 2023 reforms, the minimum daily and weekly liquid asset requirements were raised to 25% and 50% of total assets respectively. The SEC also removed redemption gates for non-government funds and introduced mandatory liquidity fees for institutional prime and institutional tax-exempt MMFs when net redemptions exceed 5% of net assets. US MMFs are not FDIC-insured, though government MMFs carry extremely low credit risk given their holdings.
Market Size and Development
The US market dwarfs both African markets in absolute terms. US money market funds held approximately $7.75 trillion in total financial assets as of end-2025, up from $6.85 trillion in 2024 — a scale that reflects decades of institutional infrastructure, deep capital markets, and widespread retail adoption.
Kenya's MMF sector, while far smaller in absolute terms, has grown rapidly. Over 3.2 million Kenyans are now invested in Collective Investment Schemes (CIS) products, a figure that more than doubled in 2025 alone, according to published CMA and industry data. The sector has shifted from a tool for high-net-worth investors to a mainstream retail product accessible via mobile phone.
Ghana's MMF industry is smaller and younger than Kenya's. Databank's MFUND, launched in January 2004, was the first licensed money market mutual fund in Ghana's history. The market now includes funds from SEM Capital, Fidelity Securities, EDC Investments, and others — but overall adoption remains lower, partly because the sector is still recovering from the 2019 financial sector cleanup which saw several fund managers lose their licences.
Yields and Returns
Yields across all three markets are shaped by local monetary policy and macroeconomic conditions.
In Kenya, the CBK entered a rate-cutting cycle in 2025, and net MMF yields have been adjusting downward from the elevated levels seen in 2023–2024 when T-bill rates were high. Net-of-fee yields among leading funds as of early 2026 varied roughly between 10% and 14% per annum, depending on fund size, management fees, and portfolio composition. Dollar-denominated Kenyan MMFs, which hedge against KES depreciation, were offering net yields in the range of 5–6% as of late 2025.
In Ghana, money market rates have historically been elevated due to higher inflation and sovereign borrowing costs. Ghana's T-bill rates in 2025–2026 ranged in the 10–13% band, making MMFs that track government securities attractive in nominal terms — though inflation erodes some of that return in real terms.
In the United States, the Federal Reserve began cutting rates in September 2024, bringing the upper end of the policy rate from 5.5% down to 3.75% by early 2026. Accordingly, US MMF yields have declined. Leading government and prime MMFs were offering 7-day SEC yields in the 3.6–4% range as of mid-2026. While this is lower than recent peak yields, US MMFs still attract investors because of their scale, liquidity depth, and the $1.00 stable NAV structure most retail government funds maintain.
Similarities
All three markets share the fundamental characteristics of money market investing: short maturity instruments, high credit quality requirements, daily or near-daily liquidity, and regulatory frameworks designed to protect investor capital. In all three, MMFs sit in the same strategic role — a place to park short-term cash above the rate of a savings account without taking on meaningful principal risk.
Minimum investment thresholds are also meaningfully accessible across all three markets. Ghanaian funds have some of the most accessible entry points globally — SEM Capital's Money Plus Fund sets a minimum of GH¢50, and Fidelity Securities Limited allows top-ups of GH¢10. Kenyan funds start as low as KES 1,000 in many cases. US retail MMFs typically require $1,000 to $3,000, with ETF-structured money market products available with no minimum.
Key Differences
The most significant structural difference is deposit insurance and currency risk. US investors in government MMFs face near-zero credit risk given the nature of US Treasury obligations, and dollar stability removes currency erosion. Kenyan and Ghanaian investors face local currency depreciation risk — a KES-denominated MMF earning 12% per annum may deliver a real return of 5–6% after inflation, and a negative real return in US dollar terms if the shilling weakens significantly.
The 2019 Ghanaian financial sector cleanup also left a scar on investor confidence that Kenya and the US do not share to the same degree. Several fund managers lost their licences and investor funds were impaired, which has made due diligence on fund manager reputation more important for Ghanaian retail investors than in either Kenya or the United States.
Conclusion
Money market funds are a reliable, low-risk instrument for managing short-term capital — not a wealth-building vehicle, but a practical tool that beats a savings account without exposing you to market volatility. Whether you are a working professional in Nairobi building an emergency fund, a business owner in Accra managing working capital, or an institutional investor in New York holding cash between deployments, the core logic is the same: let your idle money earn something while staying accessible.
The practical decisions — which fund, which market, which currency — depend on your local monetary environment, the fee structure of the fund, and your own timeline. Always compare net-of-fee returns. Always confirm the regulator has licensed the fund manager. And always treat an MMF as one part of a broader financial strategy, not the whole of it.
