What to watch out for

  • The 5% yearly charge is more than double what any money market fund on this board charges.
  • On top of that, 10% of any return above 25% in a year goes to the manager.
  • Your money is locked in for the first 6 months.
  • The fund uses derivatives and foreign markets. It can lose money, unlike a money market fund.
  • Standard Investment Bank prints "past performance is no guarantee of future performance" beside its growth chart.
  • The fund is supervised by the Capital Markets Authority.

You'd end up with
KES 622,038
If you stop after 2 years instead

You would have paid in KES 250,000 and get back KES 359,990.

  • · Based on putting in KES 250,000 once and leaving it for 5 years — the smallest way into this one.
  • · Their yearly charge is already taken out of the rate they advertise.
  • · The value goes up and down. This is not a promise.
  • · Worked out from the company's own published figures.

What does it cost you?

Charge for taking money outyour withdrawals. The redemption fee is stated as 0%Nothing

What if you stop paying?

Nothing happens. There is no set payment to keep up. What you have put in stays invested.

What if you need the money early?

You cannot touch it for the first 6 months. After that there is no charge, and the money takes two or three days to reach you.

Who this suits

It could work for you if

You have KES 250,000 spare, you can leave it for years, and you accept it may fall.

Think twice if

You may need the money soon, or a 5% yearly charge is more than you want to pay.

How current is this rate?

The 18.37% on this page is the rate Standard Investment Bank last declared, as at 2026-06-30 — 4 months old.

Standard Investment Bank states an average net return of 18.37% a year since the fund started in January 2019, after its charges. Its Q2 2026 fact sheet shows KES 1,000,000 put in on 1 January 2019 growing to KES 3,808,275.61 by 30 June 2026, after fees. The fund's own web page still shows the older figure of 18.13%. Past years are not a promise about future ones, and the fund says so.
