Stock market selloff wipes $4bn off Nigerian billionaires’ fortune

The sharp selloff on the Nigerian Exchange Limited (NGX) is eroding not only the portfolios of retail investors but also the fortunes of the country’s wealthiest businessmen, with Aliko Dangote and Abdul Samad Rabiu losing a combined $3.5 billion in just 17 days as heavyweight stocks came under intense pressure.

Data from the Bloomberg Billionaires Index, which tracks the wealth of the world’s 500 richest individuals, shows that the combined net worth of the two Nigerian billionaires declined to $50.7 billion on June 25 from $54.2 billion on June 8.

The decline mirrors a correction in some of Nigeria’s largest listed companies, particularly Dangote Cement and BUA Cement, whose shares have come under sustained selling pressure.

Africa’s richest man saw his fortune fall to $34.3 billion after briefly almost nearing the $40 billion mark earlier this month. The decline followed a 10 percent plunge in Dangote Cement’s share price on Wednesday, wiping N1.8 trillion off the company’s market capitalisation, which fell to N16.3 trillion from N18.1 trillion on Tuesday.

The drop cost the continent’s biggest cement producer its position as the Nigerian Exchange’s most valuable listed company. MTN Nigeria now leads with a market capitalisation of N17.43 trillion, followed by BUA Foods at N16.9 trillion, Airtel Africa at N16.4 trillion, and Dangote Cement.

Dangote owns 87.45 percent of Dangote Cement, making movements in the company’s share price the biggest driver of changes in his personal wealth.

Rabiu, founder of BUA Group, also saw his fortune decline as investors sold shares in his flagship listed companies. He owns 95.8 percent of BUA Cement and 92.6 percent of BUA Foods, leaving his net worth closely tied to the performance of both companies.

BUA Foods shares slipped to N939 from N967 earlier in the month, while BUA Cement fell to N340.2 on Wednesday from N378 on June 11, reducing the value of Rabiu’s holdings.

The decline pushed Rabiu behind South African luxury goods billionaire Johann Rupert, who reclaimed the position of Africa’s second-richest person after a rally in Richemont shares lifted his fortune to $20 billion.

The losses underscore how quickly fortunes tied to concentrated equity holdings can change as market sentiment shifts.

After delivering one of the world’s best equity performances in 2025, the NGX has entered a sharp correction, driven by widespread profit-taking and weakening investor sentiment.

On Wednesday, the stock market’s All-Share Index fell 2.35 percent, its biggest single-day decline in June and among the steepest daily losses this year. The selloff dragged the market’s year-to-date return down to 51.06 percent, below the record 51.19 percent gain recorded for the whole of 2025.

Heavyweight stocks including Dangote Cement, BUA Cement and Geregu Power all closed at the maximum daily decline of 10 percent, triggering a broad market retreat.

The market capitalisation of the Nigerian Exchange dropped to N150.85 trillion, while the benchmark All-Share Index closed at 235,074.54 points.

Dangote Cement fell below the N1,000-per-share mark, dropping from N1,070 to N963 in a single trading session. BUA Cement declined from N378 to N340.20, while Geregu Power also slipped below N1,000, falling from N1,019.30 to N917.40.

The selloff comes after an extraordinary rally that made Nigerian equities one of the best-performing frontier markets globally. The benchmark index gained 51.19 percent in 2025, its strongest annual performance in nearly two decades.

In response to heightened market volatility, the Exchange has announced a significant change to its pricing methodology, replacing the temporary uniform price movement rule with a three-tier price limit system based on individual share prices, a move aimed at improving market efficiency while maintaining orderly trading.
