Very few investment funds promise an annual return of above 15%, yet that is what SIB Mansa X, an investment product by Standard Investment Bank, has averaged since its launch in 2019.
Unlike most funds in Kenya, Mansa X invests not only in Kenya’s stock exchange but also in recognizable global trendsetters, such as the New York Stock Exchange (NYSE), the Hong Kong Stock Exchange (HKG), the London Stock Exchange (LSE), and the Frankfurt Stock Exchange (FRA).
So, its portfolio is widely diversified, explaining the high return rate.
The minimum investment amount is slightly higher than most money market funds, given that you need at least KES 250,000 (or USD 2,500) and at least KES 100,000 (or USD 1,000) in top-ups.
There is, however, no initial or redemption fee, and the annual management fee is only 5% pro-rated daily.

What Is Mansa-X?
Mansa X is a CMA-certified multi-asset strategy fund that invests in local and international money markets. The fund is a product of Standard Investment Bank (SIB), a CMA-certified financial service firm in Kenya. So, yes, Mansa X is certified by the Kenya Capital Markets Authority (CMA).
The Standard Investment Bank has been one of Kenya’s leading investment firms since its founding in 1995, but it only launched Mansa X in 2019.
Locally, Mansa X focuses on NSE Equities, cash and cash equivalents, NSE derivatives, fixed income, and Exchange-Traded Funds (ETFs).

Mansa X Objectives
Mansa X has three primary objectives as follows:
1. Capital preservation – Mansa X aims to protect its investments’ monetary value and asset purchasing power to prevent potential loss.
2. Capital growth – Mansa X resolves to increase the investment and asset value over time. With them, capital appreciation is a crucial delivery.
3. Access to liquidity – Mansa X allows you easy access to funds after the 6-month lock-in period. A typical withdrawal takes 2-3 working days after the request.
How Does Mansa X Work?
Mansa X operates similarly to other investment funds, where investors pool their funds, and the money manager (in this case, the Standard Investment Bank) buys, holds (for as long as necessary), and sells investments.
The fund manager makes money through the annual management fee (currently 5% pro-rated daily) and a performance fee (10% above the hurdle rate).
As an investor, you earn through dividends (quarterly company profit payouts) and capital gains (profits from stock sales). Mansa X requires a minimum investment of at least KES 250,000 within the first six months, after which you can start enjoying the returns.
As an investor, you are allocated units or shares equivalent to your investment. As per the fund’s policy, the minimum top-up is KES 100,000.
And as I mentioned, Mansa X invests locally and globally. Locally, they invest in the following assets:
- Fixed income
- Cash & Cash equivalents
- NSE equities
- NSE derivatives
- Exchange-Traded Funds (ETFs)
And globally, the fund manager invests in the following:
- Currencies
- Commodities
- Single stocks
- Stock indices
- Fixed income
- Derivatives
- Precious metals
In addition to the investment options mentioned above, Mansa X allocates a portion of its Assets Under Management (AUM) to global markets, which Nahashon Mungai spearheads to provide an edge over other local funds and ensure consistent alpha returns to investors.
The fund’s ability to access and trade in markets such as Sydney, Tokyo, Nairobi, London, and New York 24 hours a day maximizes your earning potential.
Mansa X Performance Since Inception
Mansa X is one of the highest-yielding funds in the region. The multi-asset strategy fund has shown remarkable growth since its inception in 2019.
As of Q2 2025, the Mansa X KES fund has grown to KES 65.05 billion in Assets Under Management (AUM), representing a 27.3% increase in just the second quarter of 2025. Meanwhile, the Mansa X USD fund (launched in October 2022) has reached USD 78.88 million, showing a 19.5% growth in Q2 2025 alone.
Investors, especially those who invested early, have a reason to smile following the fund’s exceptional performance over the years.
Real Investment Growth Examples:
For the KES Fund: Someone who invested KES 1 million in January 2019 when the fund was launched saw their investment grow to approximately KES 3,118,554.06 by June 30th, 2025 after fees. That’s a remarkable 211.86% return over 78 months (6.5 years).
For the USD Fund: An investor who invested USD 10,000 in October 2022, when the USD fund was launched, would have seen their investment grow to approximately USD 13,885.59 by June 30, 2025, after fees—a 38.86% return in just 33 months (2.75 years).
Mansa X Annualized Returns Since Inception

| Average Since Inception | 23.04% | 18.04% |
The company, however, still insists that past performance doesn’t guarantee future results—a standard disclaimer for all investment funds.

Should You Invest in The Mansa-X Fund?
Several factors contribute to the decision of choosing an investment fund, including risk, return rate, minimum investment, and company reputation, among others. As far as Mansa X Standard Investment Bank online trading goes, below are its pros and cons:
The Pros
Mansa X promises these benefits to its investors:
- Diversified portfolio – Mansa X’s investment portfolio features over 200 assets. They invest in local financial instruments and global assets, which gives them an edge over other funds.
- Exceptional yield – Since launching in 2019, Mansa X KES has averaged an annualized net return of 18.04%, making it one of the highest-yielding funds in the region. In 2024, the net return rate was 19.53%, the highest since the fund’s inception. In 2025 (YTD Q3), the annualized return stands at an impressive 21.37%.
- High liquidity – Investors can access their returns or capital gains within 2-3 working days of making a request. So, you don’t have to wait long to be liquid, as the Mansa X withdrawal is pretty fast.
- 24-hour trading – Since Mansa X trades globally, it has access to markets in Sydney, Tokyo, Nairobi, London, and New York, which operate in different time zones and therefore remain open 24 hours a day.
- Short-term and long-term trading opportunities – Mansa X utilises both short-term and long-term trading models, allowing it to make profitable investments across various time horizons.
- Dollar value return – The USD fund invests in USD, potentially protecting against depreciation of the Kenyan Shilling and inflation, while offering exposure to global markets.
- Professional management – Mansa X features a team of knowledgeable and experienced investors who study the money market in Kenya and globally and take calculated risks in every investment they make.
- Proven track record – With consistent performance since 2019 and growing Assets Under Management (now over KES 65 billion), the fund has demonstrated its ability to deliver returns across different market cycles.
- Regulatory oversight – Licensed as a Special Collective Investment Scheme (CIS) by the Capital Markets Authority, providing investor protection.
The Cons
On the downside, Mansa X comes with these few concerns:
- Higher investment amount – Currently, the Mansa X minimum investment is KES 250,000 (or USD 2,500). Not many Kenyans can raise such an amount even if you give them up to 6 months.
- Higher top-up limits – This is another area where Mansa X seems unaffordable to most Kenyans. The minimum top-up is KES 100,000 (or USD 1,000), which can be too high for many willing Kenyan investors.
- The return unpredictability risk – Although Mansa X has been performing exceptionally well since its inception, there are no guarantees that its performance will remain consistent in future years. Market volatility, global economic conditions, and other factors can impact returns. So, even though the risk is lower compared to individual stock trading, it’s still a risk you must consider.
- 6-month lock-in period – Your funds are locked in for the first 6 months, meaning you cannot access them during this period, regardless of your circumstances. This lack of flexibility might not suit every one.
- Performance fees – While the 5% management fee is competitive, the 10% performance fee above the hurdle rate (25% for KES, 15% for USD) means that in very good years, you’ll pay higher fees. However, this also means the fund manager is incentivized to perform well.
Verdict – Is Mansa X Worth It?
Mansa X is absolutely worth investing in if you can meet the minimum investment requirements and are comfortable with the 6-month lock-in period. Despite being relatively expensive in terms of minimum investment, the fund delivers:
- Exceptional returns (18.04% average since inception)
- Professional management by experienced traders
- High liquidity after lock-in (2-3 days withdrawal)
- Diversification across 200+ asset classes
- 24-hour global market access
- Protection against KES depreciation (USD fund)
- Strong regulatory oversight by the CMA
The numbers speak for themselves: someone who invested KES 1 million in 2019 now has over KES 3.1 million (as of mid-2025). That’s wealth creation in action.
As Cent Warrior, we advocate investing in Mansa X as part of our 10th step to financial freedom, which you can use to create passive income that equals or exceeds your monthly expenses.

Closing Remarks
Above is everything you should know about SIB Mansa X in 2026. As a multi-asset strategy fund, Mansa X has some tremendous advantages as shared, but that doesn’t make it risk-free.
The fund has demonstrated exceptional performance since its inception in 2019, delivering consistent returns that outperform most traditional investment options in Kenya.
With an average annual net return of 18.04% for the KES fund and 12.27% for the USD fund, plus professional management and regulatory oversight, Mansa X represents a solid investment opportunity for those who can meet the minimum investment requirements.
However, you should weigh its pros and cons carefully to decide if the investment fund is worth it for your specific financial situation. Consider factors such as:
- Your investment timeline (remember the 6-month lock-in)
- Your risk tolerance (market volatility can affect returns)
- Your financial capacity (can you comfortably invest KES 250,000 or USD 2,500?)
- Your investment goals (is this for wealth creation, retirement, or passive income?)
And if you want some clarification or guidance on whether Mansa X is right for you, join the Cent Warrior family on social media; we’ll be happy to help.
