Recently, a post on X platform, appealed for transaction cost to come down on the NGX, our Stock market Exchange trading platform. The writer appealed on behalf of small retail investors who trade on NGX, saying trading cost are high and not encouraging them to fully participate in the market. He outlined why the high cost of trading on the NGX, make it unprofitable for small retail investors and what lower trading cost could mean for them, if lowered and becomes more inclusive. When I first read it, it struck me as something that needs examining and debated in the wider market, because it affects everyone who trade or invest in the market.
It will make our Stock Market more competitive and also provides overall economic benefits for the economy.
THE IDEAL : THE FRICTIONLESS MARKET:
A major factor in the efficiency of a stock exchange is how “frictionless” it is. A frictionless market is a theoretical ideal characterized by near-zero costs, perfect information flow, and deep liquidity. In such a market, investors can buy or sell any volume of shares without significantly moving the price—a dynamic that prevents bubbles, removes short-selling constraints, and eliminates settlement delays.
While these perfect conditions do not exist in any real-world market, they serve as a vital benchmark. Modern technology has already helped dismantle many traditional barriers; today, information flow is near-perfect, allowing a small retail trader to access the same data as a major hedge fund manager.

(the recent shifting from T+3 to T+2) have further enhanced market efficiency.
THE BARRIER : HIGH COSTS AND STAGNANT TURNOVER.
A significant component of a frictionless market is the cost of trading. On the Nigerian Exchange (NGX), trading costs include regulatory fees (SEC, NGX, and CSCS charges), brokerage commissions, VAT, and Stamp Duty. When combined, these costs create a massive hurdle for profitable trading.
High-cost markets discourage retail investors, who are often priced out or forced into “buy-and-hold” strategies just to break even. Furthermore, Foreign Portfolio Investors (FPIs) are highly sensitive to transaction costs and tend to bypass expensive markets.
Currently, a typical trade on the NGX requires a 4.5% margin just to break even. This is a major deterrent. Despite massive growth in market size and turnover, driven lately by currency devaluation and inflation, the frequency of trading has remained flat. Investors simply find it unprofitable to move in and out of positions frequently.
A REGIONAL COMPARISON :
NGX vs. JSE
Among the top three stock markets in Africa (Cairo, Johannesburg, and Nigeria), the NGX is the most expensive. The Johannesburg Stock Exchange (JSE) is approximately 75% cheaper than the NGX. While operating costs in Nigeria are admittedly high, the wide gap between the NGX and JSE explains why foreign investors prioritize South Africa. For Nigeria to grow its market and attract more listings, trading volumes and liquidity , it must become more competitive.
THE SOLUTION : APPLYING THE LAFFER CURVE
Can the cost of trading be lowered?
The answer is a definitive yes.
* Halving Regulatory Fees:
While brokerage commissions (around 1.35%) are often discounted to 0.5%–1.0% by Stockbrokers looking to encourage volume, regulatory charges remain rigid. By cutting these fees by 50%, regulators could trigger the Laffer Curve effect: lower tariffs lead to higher activity. A reduction in fees would likely double or triple trade volumes, ultimately increasing total revenue for the regulators.
* Tax Reform:
Stamp Duty should be eliminated, especially since the government now enforces Capital Gains Tax. Removing this layer of friction would encourage higher trading frequency, which in turn increases government receipts through VAT and Capital Gains Tax.
MODERNISING TRADE ALERTS :
The current “Trade Alert” system is inefficient and plagued by network issues. It should be replaced with Email Alerts, which are essentially free, more reliable, and already the standard for the banking industry.
LOOKING TO THE FUTURE:
The NGX has made significant technological strides over the last decade. Many of those initial infrastructure costs have long been amortized. Both the NGX and the CSCS can afford to reduce their charges while remaining profitable.
To compete within the African space and attract the capital necessary for a $1 trillion economy, the NGX must prioritize growth through competitiveness. Reducing the friction of trading is the most critical step toward that future.
