How to Invest in Money Market Funds in 2026
By the time Ruth checked her M-Pesa balance that Friday evening, she had already made a decision.
She was tired of saving money only to watch it sit in a bank account.
For nearly two years, she had been putting aside whatever she could after paying rent, sending money home and taking care of the ordinary expenses that come with life. Sometimes she saved KSh 5,000. On a good month, she managed KSh 10,000.
Eventually, the balance started looking meaningful.
But there was a problem.
The money was earning very little, while the cost of almost everything around her kept changing.
A friend mentioned a money market fund.
“You can put the money there and earn interest,” she said.
Ruth opened her phone and searched for money market funds. Within minutes, she found dozens of options. Some advertised attractive returns. Others had very low minimum investments. Some allowed deposits and withdrawals through mobile phones.
Suddenly, choosing where to put her savings looked more complicated than she expected.
That is a common experience.
Money market funds have become much easier to access, but choosing one should involve more than downloading an app and looking at the highest advertised return.
What Is a Money Market Fund?
A money market fund, commonly called an MMF, is a type of collective investment scheme.
Instead of investing your money directly into individual short-term securities, you pool your money with that of other investors. A professional fund manager then invests the pooled funds according to the fund’s investment mandate.
The Capital Markets Authority regulates collective investment schemes in Kenya, and money market funds form part of this regulated investment market. CMA continues to approve new unit trust schemes and sub-funds, including KES and USD money market products.
The investments held by a money market fund can include short-term government securities and other permitted money-market instruments, depending on the fund’s mandate.
This is important because when you put KSh 20,000 into an MMF, the fund manager is not simply keeping your cash in a separate bank account.
Your money becomes part of a professionally managed investment portfolio.
How Does a Money Market Fund Make Money?
The fund earns income from the investments it holds.
For example, a fund may invest in Treasury bills and other short-term instruments that generate interest.
The income earned by the underlying portfolio contributes to the fund’s return, after applicable expenses and charges.
This is why the return from an MMF can change over time.
If market interest rates change, the income available from new investments can also change. A fund that was producing a particular annualised return several months ago may produce a different return later.
This is one reason you should be careful when you see an advertisement saying a money market fund is paying a particular percentage.
That figure is not necessarily a guaranteed future return.
Are Money Market Funds Safe?
This is where many articles get it wrong.
Money market funds are generally considered lower-risk investments, but they are not risk-free.
The level of risk depends partly on what the fund invests in.
A fund investing predominantly in government securities may have a different risk profile from one with greater exposure to corporate instruments.
There are also investment, liquidity, interest-rate and operational risks.
The fact that a fund’s unit price appears stable does not mean losses are impossible.
CMA’s regulatory framework provides oversight of collective investment schemes, and fund structures include roles such as the fund manager, trustee and custodian. The Authority has also emphasised the importance of segregation of client assets and independent oversight in the unit-trust structure.
So the better description is relatively low risk, not “no risk.”
Why Are MMFs Popular in Kenya?
Part of the attraction is convenience.
A few years ago, investing often meant visiting an office, completing paperwork and waiting for an account to be opened.
Today, many regulated funds have digital onboarding and payment options.
You can potentially start with a relatively small amount, monitor your investment from your phone and request a withdrawal without visiting a physical office.
That convenience has lowered the barrier to investing.
CMA has itself linked the growing interest in collective investment schemes to increased retail awareness and the digitisation of investment processes.
But convenience should not replace due diligence.
An investment app can make investing easier.
It cannot tell you whether a particular fund is appropriate for your financial goal.
How Much Money Do You Need to Start?
There is no single minimum amount for every money market fund.
Each fund sets its own requirements.
Some allow investors to start with a few hundred shillings, while others require a higher initial contribution.
This means you should not choose an MMF simply because it has the lowest minimum.
If Fund A requires KSh 500 and Fund B requires KSh 5,000, that does not automatically make Fund A better.
The more important questions are:
- Who manages the fund?
- Is the fund approved by CMA?
- What does it invest in?
- What are the fees?
- What has its recent performance looked like?
- How easy is it to withdraw?
- Are there minimum balance requirements?
- How are returns reported?
- What risks are disclosed?
The minimum investment is only one part of the decision.
How to Choose a Money Market Fund
This is where Ruth spent most of her time.
She had initially planned to choose the fund showing the highest return.
Then she realised that comparing MMFs requires looking beyond one number.
Check That the Fund Is Regulated
Start with CMA.
The Authority maintains a public list of licensed collective investment schemes and fund managers. Its current register includes numerous KES and USD money market funds from different providers.
Do not assume that a fund is legitimate simply because it has a professional website, a large social-media following or an attractive mobile application.
Verify it.
This should be the first filter.
Look at What the Fund Invests In
Two money market funds can produce different results because their portfolios are not necessarily identical.
Look at the fund’s investment policy and portfolio information.
Some funds may have greater exposure to government securities, while others may invest in permitted corporate instruments.
Understanding the underlying portfolio gives you a better picture of where your money is going.
Compare Returns Carefully
Returns are important, but do not chase the highest number you see.
A fund showing a high recent annualised return may not continue producing that rate.
Market conditions change.
The current interest-rate environment in Kenya illustrates why this matters. CBK’s latest published figures show the Central Bank Rate at 8.75%, while the previous average rates for 91-, 182- and 364-day Treasury bills were about 8.77%, 8.93% and 9.07%, respectively.
Because many MMFs invest in short-term instruments, changes in market yields can eventually affect the income available to the fund.
So instead of asking, “Which fund has the highest return today?” ask:
“How has this fund performed over different periods, and why?”
Check the Fees
Your return is affected by costs.
Look for management fees and any other charges that apply.
A fund with a slightly lower headline return may leave you with a competitive net return if its cost structure is more favourable.
Do not compare funds using advertised returns without understanding whether the figures are gross or net of the relevant expenses.
Understand the Withdrawal Process
Liquidity is one of the main reasons people choose MMFs.
But “liquid” does not necessarily mean “instant.”
The fund will have its own withdrawal process, cut-off times and settlement arrangements.
Before investing, find out:
- How do I request a withdrawal?
- How long does it normally take?
- Are there cut-off times?
- Is there a minimum balance?
- Are there withdrawal charges?
- Does the fund allow partial withdrawals?
This becomes especially important if you intend to use the MMF for emergency savings.
Can You Use an MMF as an Emergency Fund?
Yes, an MMF can be useful for emergency savings because it can provide a place to keep money that is relatively liquid while potentially earning more than a conventional low-interest savings account.
But do not put every shilling of your emergency money into an investment without checking the fund’s withdrawal terms.
If you need cash immediately, you should know exactly how quickly you can access it.
The purpose of an emergency fund is not to maximise returns.
It is to make sure that an unexpected expense does not force you into expensive debt.
That distinction matters.
MMF vs Savings Account
Ruth’s original question was simple:
“Why should I put my savings into an MMF instead of leaving them in the bank?”
The answer depends on what the money is for.
A bank savings account is designed primarily for accessible cash and banking transactions. A money market fund is an investment product.
An MMF may potentially provide a higher return, but the return is not guaranteed in the same way people sometimes assume.
A savings account may also offer immediate access through your bank’s normal payment channels, while an MMF has its own withdrawal and settlement process.
You should therefore consider both return and accessibility.
If you are keeping KSh 10,000 for tomorrow’s groceries, accessibility may matter more than earning a little additional income.
If you have KSh 200,000 that you do not expect to need immediately, the calculation may be different.
MMF vs Fixed Deposit
A fixed deposit locks your money with a bank for an agreed period in exchange for interest under the bank’s terms.
An MMF invests your money in a portfolio of short-term instruments and generally allows withdrawals subject to the fund’s rules.
The difference becomes important when your circumstances change.
With a fixed deposit, withdrawing before the agreed maturity can affect the interest you receive or may be subject to specific conditions.
With an MMF, you generally have more flexibility, although you still need to understand the withdrawal process.
Neither is automatically better.
Your choice should depend on how much flexibility you need and what you are trying to achieve.
MMF vs Treasury Bills
Treasury bills are short-term government securities issued by the Central Bank of Kenya.
The current Treasury-bill market includes 91-day, 182-day and 364-day bills. CBK’s latest published previous average rates were approximately 8.77%, 8.93% and 9.07% respectively.
When you buy a Treasury bill directly, you are investing in a specific government security.
When you invest in an MMF, the fund manager invests pooled money across eligible short-term instruments.
This creates an important difference.
With a Treasury bill, you make the investment decision yourself.
With an MMF, you are paying for professional portfolio management.
That convenience can be valuable, particularly for someone who does not want to research and manage individual securities.
What About Taxes?
Tax is another area investors should not ignore.
Interest income can be subject to withholding tax, depending on the nature of the income and the taxpayer.
KRA currently lists a 15% withholding-tax rate for qualifying interest, with the precise tax treatment depending on the income and taxpayer circumstances.
Do not assume that an advertised MMF return is the exact amount that will land in your pocket.
Ask the fund manager how the quoted return is calculated and what charges and tax considerations apply.
When comparing investments, focus on what you actually expect to receive after relevant costs and taxes.
How to Start Investing in an MMF
Once you have chosen a suitable fund, the actual process is usually straightforward.
Step 1: Set Your Goal
Do not begin with the app.
Begin with the reason for investing.
Are you building an emergency fund?
Saving for school fees?
Holding money for a business expense?
Keeping cash aside while you decide on a longer-term investment?
Your goal determines how much liquidity you need and how long you expect the money to remain invested.
Step 2: Verify the Fund
Check the CMA register.
Confirm the name of the fund and the entity managing it.
Do not rely only on a social-media advertisement or a friend’s recommendation.
Step 3: Read the Fund Documents
Look at the fund’s information documents before sending money.
Pay attention to the investment objective, permitted investments, fees, risks, withdrawal arrangements and other important terms.
You do not need to become a professional fund manager.
But you should know what you are buying.
Step 4: Open Your Account
Follow the fund’s official onboarding process.
You may be asked for identification and other information required for account opening and regulatory compliance.
Use the fund manager’s official channels.
Step 5: Deposit Your Money
Transfer your investment through the approved payment method.
Keep records of your deposits.
Step 6: Monitor Without Obsessing
Once your money is invested, you do not need to check the balance every hour.
Remember why you invested.
If the fund is serving as an emergency reserve, the most important thing may be knowing that the money is available when needed—not watching a small daily change in your balance.
How Much Should You Put in an MMF?
There is no universal percentage that every person should invest.
Start with your financial situation.
If you have expensive debt, it may make more sense to address that first.
If you have no emergency reserve, building one may be more important than chasing higher-risk investments.
If you already have savings and want somewhere to keep short-term money while earning a return, an MMF may be useful.
For someone earning KSh 60,000 a month, for example, the right contribution could be very different from that of someone earning KSh 300,000.
Your investment should fit your income, expenses, obligations and goals.
Can You Lose Money in a Money Market Fund?
Yes.
Although MMFs are designed to invest in relatively short-term and lower-risk instruments, they are still investment products.
The value and income generated by the fund depend on the assets it holds and prevailing market conditions.
A prime money market fund, for example, may have exposure to corporate debt instruments and therefore carry credit risk from those investments.
This is why the phrase “guaranteed return” should make you pause.
If someone promises that your money will earn a fixed high return with no possibility of loss, investigate carefully.
An investment product regulated by CMA is not the same thing as a government guarantee of your investment.
Should You Keep Your Entire Portfolio in an MMF?
An MMF can be an excellent part of a financial plan.
It does not necessarily need to be the whole plan.
Think about the different jobs your money needs to perform.
Some money may need to remain accessible.
Some may be invested for several years.
Some may be intended to generate income.
Some may be invested for long-term growth.
A money market fund is particularly useful for the first category—money that needs relatively high liquidity and lower volatility.
But long-term wealth creation may require exposure to other investments depending on your circumstances and risk tolerance.
Diversification matters.
CMA continues to expand the range of regulated collective investment products available to investors, including money market, fixed-income, equity and multi-asset funds.
The growing number of products means investors have more choice, but it also means they need to compare carefully.
Common Mistakes to Avoid
Choosing the Fund With the Highest Return
Today’s highest return may not be tomorrow’s highest return.
Look at consistency, investment strategy, fees and risk.
Assuming Your Money Is Guaranteed
An MMF is a regulated investment, not a bank savings account with a guaranteed return.
Understand the risks.
Ignoring Fees
Small charges can reduce your investment income over time.
Read the fund’s fee structure.
Treating an MMF Like a Current Account
Liquidity does not mean unlimited instant access.
Understand the withdrawal process before relying on the fund for urgent expenses.
Putting Money You Need Immediately Into an Investment
If you need the money tomorrow morning, think carefully before putting it somewhere with a withdrawal process.
Keep genuinely immediate cash accessible.
Following Social-Media Recommendations Blindly
Someone else’s favourite MMF may not be the right one for you.
Do your own checks.
Ignoring Inflation
A positive return does not automatically mean your wealth has grown significantly in real terms.
If inflation is high, part of your return may simply be compensating for the rising cost of goods and services.
CBK’s latest figures put annual inflation at 6.6% for August 2026.
That makes the difference between the nominal return and your real purchasing-power growth worth considering.
A Simple Way to Compare MMFs
Before choosing a fund, create a small comparison table.
| What to Check | Fund A | Fund B | Fund C |
| CMA-regulated | ✓ / ✗ | ✓ / ✗ | ✓ / ✗ |
| Minimum investment | |||
| Recent annualised return | |||
| Management fees | |||
| Withdrawal process | |||
| Investment strategy | |||
| Minimum balance | |||
| Additional charges |
You do not need twenty columns.
A simple comparison can prevent you from making a decision based on one attractive number.
Is a Money Market Fund Right for You?
An MMF may make sense if you:
- Want a relatively low-risk investment.
- Need relatively easy access to your money.
- Are building an emergency fund.
- Have short- or medium-term financial goals.
- Want professional management of your money.
- Are looking for an alternative to keeping all your spare cash in a low-interest account.
It may not be the right place for money you want to grow aggressively over a very long period.
It may also not be suitable for money you need immediately unless you have confirmed that the withdrawal process meets your needs.
The Best MMF Is Not Necessarily the One With the Highest Return
Ruth eventually chose a money market fund.
But she did something else first.
She compared the fund’s regulator, manager, investment strategy, fees, withdrawal process and historical performance. She also separated the money she might need immediately from the money she could leave invested.
That exercise changed her understanding of what investing meant.
She had started by asking:
“Which MMF is paying the most?”
She ended with a much better question:
“Which fund fits the job I need this money to do?”
That is the question worth asking before you invest.
Money market funds can be useful because they combine professional management, access to short-term investments and relatively high liquidity. But they are not magic accounts that guarantee high returns or eliminate investment risk.
Choose a regulated fund. Understand what it invests in. Look beyond the headline return. Check the fees and withdrawal terms. Know the tax implications. And keep the purpose of your money in mind.
For Ruth, the goal was never simply to find a place where her money could earn interest.
She wanted to stop watching her savings sit idle while she was working hard to build them.
The MMF became one part of that plan—not the entire plan.
And that is a much healthier way to think about investing.
