The single biggest factor in where your money should go isn’t how much you have — it’s how long before you need it. ₦500,000 you’ll touch in six months and ₦500,000 you won’t touch for five years belong in completely different places, even though the amount is identical.
Short answer: for money you need within a year, prioritize access — a Money Market Fund or a short Treasury Bill. For one to two years, a longer Treasury Bill or a mix works well. Beyond that, you have room to consider things that carry more short-term movement but historically reward patience, like Nigerian stocks or real assets — provided you genuinely won’t need the money before then.
Under 6 months: prioritize access over return
If there’s a real chance you’ll need this money within six months, the return you could earn matters less than being able to actually get to it without a penalty or a delay you can’t afford. A Money Market Fund is usually the right call here — you still earn meaningfully more than a savings account, and most platforms let you withdraw within a day or two. Locking this money into a Treasury Bill with a longer tenor, or into anything less liquid, creates a real risk of needing cash and not having a clean way to get it without a loss.
6 months to 1 year: Treasury Bills earn their place
Once you’re confident the money won’t be needed for six months to a year, a Treasury Bill in that tenor range becomes genuinely competitive with an MMF, and sometimes pays more, since the rate is fixed and known the day you buy rather than moving with the market. The trade-off is that it’s locked for the full term — if your plans change, you’re either waiting it out or selling into the secondary market, which isn’t guaranteed to be favorable.
1 to 2 years: room to split, room to be more deliberate
At this horizon, a straight either-or choice matters less than deliberately splitting — part in a 364-day Treasury Bill for a known return, part in an MMF for flexibility in case something changes sooner than planned. This is also where it’s worth checking whether reinvestment risk applies to you: if rates are falling, as Nigeria’s Treasury Bill rates have been through 2026, locking in a longer tenor now can protect you against a lower rate at the next auction.
3 years and beyond: where genuine growth assets start to make sense
Money you won’t need for three years or more can reasonably carry more short-term movement in exchange for higher long-run potential — Nigerian stocks on the NGX, for instance, or other growth-oriented assets. This isn’t a claim that stocks will outperform — markets can and do fall over any given year — but a multi-year horizon gives you time to recover from a bad stretch in a way a six-month horizon simply doesn’t. If you’re new to this, start by understanding what you’re actually buying rather than chasing a tip; NairaSeed’s beginner investing guide is a reasonable place to start.
A practical example
Say you have ₦1,200,000 total: ₦300,000 you might need within the year for a planned expense, ₦400,000 you’re fairly confident you won’t touch for about two years, and ₦500,000 that’s genuinely long-term, set aside for something five years out. A reasonable shape: the ₦300,000 in an MMF for access, the ₦400,000 split between a Treasury Bill and an MMF, and the ₦500,000 left to grow somewhere with more room to move, since you have time to ride out any short-term swings.
Risks and caveats
Being wrong about your own time horizon is the biggest risk here — people frequently underestimate how soon they’ll actually need money, and locking funds away based on an overly optimistic timeline can force an expensive early exit. When in doubt, lean toward the more liquid option; the cost of slightly lower returns is almost always smaller than the cost of being forced to sell something illiquid at a bad moment.
What to do next
Be honest about your actual time horizon for each portion of your money, not just the total amount. Use the calculator below for the MMF-versus-Treasury-Bill portion of the decision once you know which bucket a given amount falls into.

FAQ
What if I’m not sure how long I’ll need the money for?
When your timeline is genuinely uncertain, treat it as the shorter estimate and prioritize access — it’s far less costly to earn slightly less on money you didn’t need to touch than to be forced to sell something illiquid early.
Does inflation change this?
Yes — money sitting too conservatively for too long can lose real value to inflation, which is part of why a multi-year horizon is worth considering growth assets for, rather than defaulting to the safest option regardless of timeline.
