You’ve probably heard a friend say “just put it in an MMF.” But what actually happens to your money once it’s in one? Here are the six questions people ask most, answered straight.

1What is a money market fund?

A money market fund (MMF) is a pool of money from thousands of investors, managed by a licensed fund manager. That manager puts the pool into low-risk, short-term instruments — treasury bills, bank fixed deposits, and high-quality commercial paper — and pays you a share of the interest those instruments earn.

You can put money in and take it out without locking it away for a fixed term, which is why MMFs have become a popular alternative to a plain savings account in Kenya. Here are three of the highest-paying funds right now:

CytonnCytonn Money Market Fund11.1%
FauluFaulu Money Market Fund11.0%
Lofty-CorbanLofty-Corban Money Market Fund10.7%

2Is my money safe?

Money market funds in Kenya are regulated by the Capital Markets Authority (CMA), and losing your principal is rare. But “rare” is not the same as “impossible” — an MMF is not a bank deposit, it carries no deposit insurance, and its yield is not guaranteed. It moves with interest rates, and it can fall.

Worth knowing. In January 2025, investors in the Mali MMF reported delays withdrawing their money after the fund’s manager, Genghis Capital, became entangled in a debt dispute. The regulator stated that client assets are held in accounts separate from the manager’s own funds. Separately, some of Cytonn’s other investment products — not its money market fund — have had unpaid investors and ongoing court cases. These are the kind of situations that make “regulated” worth double-checking rather than assuming.

Before you put money into any fund, it’s worth checking three things: that it’s licensed by the CMA, who manages it, and how large the fund is. A bigger, longer-track-record fund is generally easier to get comfortable with than a brand-new one offering the highest rate on the table.

3How fast can I get my money out?

There’s no lock-in period on a money market fund — you can ask for a withdrawal any time. Most fund managers process it within 1 to 4 working days. A handful of funds move faster: Ziidi, for example, can pay out the same day through M-Pesa.

4How much tax do I pay?

Interest from a money market fund is subject to a 15% withholding tax, deducted automatically by the fund manager before your interest is credited. That means the headline rate you see advertised is never what actually lands in your account. Here’s what that looks like on KES 100,000 invested in a fund paying 11.1%:

1Interest earned: 100,000 × 11.1% = KES 11,100
2Tax withheld: 11,100 × 15% = KES 1,665
3What you actually keep: 11,100 − 1,665 = KES 9,435

So an advertised 11.1% really pays you about 9.4% net, over one year.

5How much do I need to start?

KES 100
Cytonn, Ziidi and a few others
KES 1,000+
Most funds
KES 1,000,000
The highest minimums, a few funds

Minimums vary a lot from fund to fund, so it’s worth checking the exact figure for any fund you’re considering — it can be the difference between starting today and having to save up first.

6Which fund pays the most?

As of September 2026, Cytonn leads at 11.1%, followed by Faulu at 11.0% and Lofty-Corban at 10.7%. The average across all 32 funds we track is 9.2% — and the lowest-paying fund sits at just 4.9%. That’s a wide gap for what looks, on the surface, like the same product.

7Who is an MMF actually suitable for?

An MMF works best as a place for money you don’t want tied up but also don’t want sitting idle — the classic case is an emergency fund, or savings for something 6–18 months out (school fees, a deposit, a tax bill), where you want a better return than a plain bank savings account (typically 3–7% in Kenya) without locking your money away in a fixed deposit.

Yet most Kenyans with surplus cash still don’t reach for one. When we asked people with surplus cash what they actually do with it:

66%
choose a fixed deposit
20%
leave it in a savings account they rarely access
14%
put it into an MMF

That gap is part of why we built WeCompare — most people simply haven’t compared what each option actually pays.

Where MMFs do get used, two groups stand out in our data: 58% of the small business owners we spoke to use one to hold working capital they don’t need immediately but might need on short notice, and 42% are people who want to start investing but aren’t ready for the volatility of stocks or the illiquidity of real estate or SACCO shares.

They also suit salaried people parking a bonus or year-end payment before deciding what to do with it long-term, and anyone building an emergency fund who wants it to earn something while staying liquid.

Where they’re a poor fit. Money you need in a fixed amount on a fixed date, and can’t afford any variance on — a fund’s return floats with market rates, it’s not guaranteed like a fixed deposit. Genuinely long-term money (retirement, 10+ year goals), where equities or a pension scheme have historically outgrown MMF returns over time. And money you can’t afford to see at risk at all — MMFs aren’t deposit-insured in Kenya, and while losses are rare, they’ve happened (see “Is my money safe?” above).

Suitability also comes down to withdrawal speed. If you need same-day access, that narrows the field to funds like Ziidi with M-Pesa same-day withdrawal, rather than the 1–4 working day norm that most funds — including the top payers, Cytonn and Faulu — operate on.

8Can I use an MMF as a source of income?

Yes — this is one of the more common real-world uses for MMFs in Kenya. Most funds let you choose to receive interest as a monthly payout rather than reinvesting it, which effectively turns your principal into an income stream.

The catch is scale. At the after-tax yields in the table above — roughly 7–9.5% depending on the fund — the income a given principal throws off is modest unless the principal itself is large. KES 1,000,000 in Cytonn at 9.47% after tax works out to about KES 7,890 a month. To reach something closer to a living wage — say, KES 50,000 a month — you’d need roughly KES 6.3 million in the fund at that rate.

That makes it realistic as a source of income for someone with a lump sum — a pension payout, proceeds from a property sale, an inheritance — or as a supplement to a salary, but not typically a standalone income strategy if you’re starting from a small base.

Worth knowing. Unlike a salary or a fixed annuity, this income isn’t fixed. The rate floats with the market, so the payout this month can differ from last month’s, sometimes by a meaningful margin over a year or two as rates cycle.
