If you have been keeping an eye on the business news, you have probably seen the exciting headlines. By August 2025, significant events had occurred at the Nairobi Securities Exchange (NSE). Foreign investors (individuals and institutions), in a show of renewed confidence, had poured a net kshs 1.6 billion into the market. This is the highest figure we have seen in four years.
This is not just a dry statistic for stockbrokers and fund managers to celebrate. This surge of activity has a straightforward and positive trickle-down effect. One of the biggest beneficiaries is something that might sound a bit technical but affects us all: Capital Gains Tax (CGT).
Let us break down what this foreign investor frenzy really means for Kenya’s public coffers through the lens of CGT.
First, A Quick Refresher: What is Capital Gains Tax?
In simple, conversational terms, Capital Gains Tax is a levy paid on the profit you make when you sell an asset that has increased in value. It is not included in the total selling price, just in the gain. Remember, the investor has to deduct other expenses to arrive at the net capital gain to be taxed.
For example, if a foreign investor buys shares in a Kenyan company for kshs 10 million and later sells them for kshs 15 million, they have made a capital gain of KShs 5 million. The Kenyan government then taxes that gain at the current rate of 15%.
So, in this case, Ksh 750,000 would be paid as Capital Gains Tax to the Kenya Revenue Authority (KRA). This tax is a crucial source of revenue for funding public services like infrastructure, healthcare, and education.
Connecting the Dots – High Purchases Today Equals Potential CGT Tomorrow
The recent kshs 1.6 billion net purchase (and we hope more will flow in) is a powerful indicator of two things:
a. Entry Point
Foreign investors are buying Kenyan stocks now because they believe their value will rise in the future.
b. Future Exit
Eventually, these investors will look to sell these shares to realize their profits. And when they do, that 15% Capital Gains Tax will be triggered on every net shilling of profit they make.
Think of it like planting a tree. By August 2025, numerous new saplings (investments) had been planted. The harvest and the subsequent tax revenue come when those trees bear fruit upon sale.
Why the Sudden Confidence? The “Waning Worries” Effect
To understand the sudden interest in NSE shares, you need a global perspective, particularly as American tariffs continue to ease. This is key. Global investors hate uncertainty. When fears of trade wars and disruptive tariffs fade, they feel more confident investing in emerging markets like Kenya, which offer strong potential returns.
This “risk-on” sentiment means they are moving money from perceived safe havens into markets like the NSE. This increased demand drives up trading volumes and the share prices, creating a larger potential gain and therefore a larger future CGT liability.
The Multiplier Effect: More Than Just a One-Time Tax
The impact of this investment surge goes beyond the direct tax collected when shares are sold. What are the other benefits?
a. Increased Market Liquidity
High trading volumes make the market more attractive to other investors, both local and foreign. A vibrant, liquid market is a healthy market, leading to more transactions and, you guessed it, more potential CGT events.
b. Strengthened the Kenyan Shilling
Large foreign inflows of dollars to buy shares increase the supply of USD flows into the country. This will definitely help strengthen the Kenyan shilling. There are many benefits when the shilling is stronger. For example, a stronger currency will stabilise import costs and help curb inflation.
c. Corporate Growth
The investments by foreigners at the NSE are providing Kenyan companies with more equity and a higher valuation. This will make it easier for the companies to raise capital for expansion, create jobs, and contribute to economic growth through corporate taxes. The companies have international investors.
The KRA’s Role In Ensuring Tax Compliance
For this potential revenue to be realised, the Kenya Revenue Authority (KRA) has a critical role to play. The system for collecting CGT on securities is efficient because it is mainly automated. Licensed stockbrokers and investment banks act as withholding agents.
This means that when an investor (foreign or local) sells shares and makes a gain, the broker automatically deducts the 15% CGT and remits it directly to the KRA before the net proceeds are paid to the investor. This process minimises tax evasion and ensures the government gets its share from every profitable transaction.
A Word of Caution: It is Not a Guarantee
It is important to remember that the CGT revenue is contingent on those shares being sold at a profit. If, for some reason, market conditions change and these investors are forced to sell at a lower price than they bought (a capital loss), no tax is due.
However, the current trend of high purchases at low prices suggests a strong belief in future gains, making a significant CGT payout in the future a very likely scenario.
Other Taxes
The banks, brokers, NSE, and CMA will also pay taxes on the fees charged to foreign investors for various services. So, it is not only the CGT that will benefit; other tax heads will also benefit. Plus, of course, the spill-over effects on the overall economy. The National Treasury will be all smiles.
The Bottom Line For You
While this might seem like a story about big international finance, it has a real impact. The revenue generated from Capital Gains Tax contributes to the national budget. This should translate to better roads, improved public services, and potentially less public debt burden.
So, the next time you read about foreign investors flooding the NSE, see it as more than just a market headline. See it as a future investment in Kenya’s infrastructure and services, all thanks to the mechanism of Capital Gains Tax. That kshs 1.6 billion is not just sitting in the market. It is a seed planted for Kenya’s future growth and stability.
