Most emergency fund advice stops at “save three to six months of expenses” and never says where to actually put it. Leaving it in cash — a regular bank account, or literally at home — feels safest. But it’s also the option most likely to quietly lose value while it sits there doing nothing.
Short answer: for most people, a Money Market Fund is the better home for an emergency fund than plain cash — it pays a real return while still giving you access within a day or two. Keep a small, genuinely immediate slice in cash for true same-day emergencies, and let the rest earn something.
What “cash” is actually costing you
A regular bank savings account in Nigeria pays a fraction of what inflation erodes every year — the CBN’s benchmark savings deposit rate has sat well under 10% for much of 2026, while prices for everyday goods have kept climbing. Money kept as literal cash at home earns nothing at all and carries its own risks. Either way, an emergency fund sitting in cash isn’t neutral — it’s losing real value the entire time it isn’t needed.
Why a Money Market Fund fits the job
The whole point of an emergency fund is that it has to be there when you need it, without penalty or delay. A Money Market Fund matches that requirement almost as well as cash does — most platforms let you withdraw within 24–48 hours — while paying a return that has recently run well into double digits annually, depending on the fund. You’re not trading away access to get a better rate; you’re giving up almost nothing in exchange for meaningfully more.
Where cash still makes sense
Not every emergency gives you 24–48 hours of notice. If your situation genuinely calls for same-day cash — no card, no transfer, physical naira in hand — keep a smaller slice, maybe one to two weeks of essential expenses, in an easily accessible account or literally on hand. The rest of the buffer, the part covering the following months, doesn’t need that level of immediacy and shouldn’t be priced as if it does.
A practical example
Say your emergency fund target is ₦600,000, covering roughly four months of expenses. A reasonable split: ₦100,000 kept genuinely liquid — a regular account you can move from instantly — and ₦500,000 in a Money Market Fund. If a real emergency hits, the ₦100,000 covers you immediately while you withdraw the rest, and in the meantime the ₦500,000 is earning a return instead of sitting flat.
Risks and caveats
An MMF is low-risk, not risk-free — returns move with the market and aren’t guaranteed the way a bank balance is. Confirm the fund manager is genuinely SEC-registered before committing your emergency fund to it, since this is money you can’t afford to have tied up with an unreliable platform. And don’t push the “immediate cash” slice too low — the entire point of that portion is that it’s there instantly, with zero exceptions.
What to do next
Work out how much of your emergency fund genuinely needs same-day access, keep that portion in cash or a regular account, and move the rest into a Money Market Fund. If you’re starting from scratch, the emergency fund guide below walks through building the target amount first.

FAQ
Should my entire emergency fund go into a Money Market Fund?
Most people are better off keeping a small immediate-access slice in cash and putting the rest in an MMF — entirely in cash costs you return, entirely in an MMF risks a gap if you need money the same day.
What if I need the money faster than the MMF can pay out?
This is exactly why the split exists — the cash portion covers the gap while an MMF withdrawal, typically 24–48 hours, is processing.
