Africa's Public Markets Don't Need More Companies. They Need Better Institutional Capital

Introduction

The standard diagnosis of a thin market is a supply diagnosis. When Temi Popoola, the Group Managing Director and CEO of NGX Group, said in August that he expected the Nigerian market's value to reach ₦230 trillion by year-end, he tied the forecast to a pipeline: \"with the listings that we expect in our market, we expect that figure to be N230 trillion.\" The market stood at about ₦160 trillion at the time.

A fortnight later he put the second half of the task differently, saying the exchange has to \"turn greater international visibility into broader participation, deeper liquidity and more capital for Nigerian businesses.\" The first statement is about supply. The second is about demand, and it is the one this article takes seriously.

Nigeria is my evidence base, and every claim below is about Nigeria. I do not claim the numbers transfer to Johannesburg or Nairobi, though I suspect the mechanism does. Institutional capital, as I use the term, means money managed by institutions that answer to long-horizon beneficiaries, mainly pension funds, insurers and asset managers, rather than money traded for short-term gain. Free float is the share of a company's equity that is available to public investors, as opposed to shares held by controlling owners who do not trade them.

What Is Missing From African Public Markets?

A market becomes deep when buyers and sellers can transact size without moving the price, and that needs three things at once: buyers who will still be there after a bad year, buyers who can influence the companies they own, and enough stock available to buy. Listing more companies addresses none of these directly. It raises the count of tickers, which is a supply statistic, and leaves the quality of demand untouched. I take the three conditions in turn.

Does the Capital Stay Through a Cycle?

Nigeria's pension industry is the obvious candidate for durable domestic capital. The National Pension Commission (PenCom) reported pension assets of ₦31.32 trillion as of May 2026, and its Director-General called the industry's pool \"probably the largest pool of passive long-term savings capital in the country.\" Pension liabilities are long-dated by design, so the duration is real.

The question is where that capital sits. ThisDay, citing PenCom, reported that pension fund administrators' exposure to equities and Federal Government securities reached ₦23.87 trillion in April 2026. Within that, quoted equities were ₦6.5 trillion, up from ₦3.95 trillion at the end of 2025, and FGN securities were ₦17.36 trillion. By my calculation, securities are about 2.7 times equities, and equities are about 21% of the ₦30.94 trillion net asset value PenCom reported for April. The same report quotes a 77% share for government securities that does not reconcile with its own naira figures (₦17.36 trillion is about 56% of ₦30.94 trillion), so I rely on the naira figures.

The pattern is that long-dated liabilities have so far been matched mainly with sovereign paper, and the move into equities is recent and fast. I cannot observe how that capital behaves in a downturn, because it has not yet been through one at this scale, and The Upside Journal's confidence analysis sets the bar high for what counts as durable: foreign-exchange predictability through a full commodity cycle, repatriation certainty, institutional continuity and a multi-year record. Permanence by temperament is a different thing. The African Capital Builders framework describes owners who behave as permanent holders rather than on fund-cycle logic, and that is valuable, but a public market cannot rely on temperament. It needs institutions whose permanence is contractual.

Verdict: long-dated liabilities make pension capital durable in principle, and whether it is durable in equities is a question the next downturn will answer.

Does the Capital Have a Voice?

The second test is stewardship: whether holders can influence the companies they own. I could not find a published measure of how Nigerian pension fund administrators vote or engage with issuers, so this test is an argument, not a statistic.

The argument is mechanical. Where a controlling owner holds most of the equity, outside institutions are price-takers: they can sell, but they cannot steer. The First HoldCo analysis shows the tension in a single company, where the ownership concentration that made a balance-sheet clean-up possible is the same variable that caps how much of the company index capital can hold. A reformed issuer with concentrated ownership gives institutions visibility without influence, and I regard visibility without influence as liquidity, not stewardship.

What would voice look like in practice? It would show up as measurable behaviour: published voting records, engagement on disclosure and related-party transactions, and a willingness to withhold support from issuers that keep float low without explanation. None of that requires holding a majority. It requires holding enough, for long enough, that management expects the question. That is why duration and voice are linked: an institution that expects to be a shareholder for a decade has a reason to ask, and one that expects to rotate out within a year does not.

Verdict: capital that can only exit is liquidity, and a market needs capital that can also insist.

Is There Anything of Size to Own?

The third test is investable supply, and it is where the supply diagnosis fails on its own terms. Serrari Group's analysis, published in May 2026 and based on an ownership database of more than 200 Nigerian listed companies, estimates that of a ₦129 trillion market capitalisation roughly ₦45 trillion is investable and about ₦84 trillion is locked in controlling holdings. That is a free float of about 35%. The three largest names account for around 42% of the benchmark index's weighting, yet have single-digit or barely double-digit free floats: the second-largest at about 5%, the fourth-largest at 2.3%.

These are one analyst's estimates, compiled before the market rose further in the summer, and I treat them as indicative. They do not need to be exact to make the point. If most of the largest companies trade only a sliver of their equity, listing additional companies adds weight to the index that institutions still cannot buy.

The largest offering in the pipeline illustrates it. The Dangote refinery offer raises ₦2.15 trillion through 4.1 billion new shares at ₦525, which places 3.3% of the enlarged company in public hands. It is a large raise and a thin float at the same time, and it is the supply the NGX forecast leans on. Sources differ on when the subscription window closes, and I have not verified a single closing date against the offer document, so I give none.

The practical reading is that float, not capitalisation, is the number an allocator should ask for first. Capitalisation tells an investor how large a company is on paper. Float tells the investor how much of it can change hands, and therefore how large a position can be built or sold without the price moving against it. A market in which the biggest companies have the smallest floats is one in which the most visible assets are the hardest to trade, and that is a depth problem no listing count can fix.

Verdict: a listing that adds shares nobody can buy adds a ticker, not depth.

What Do the Data Say Against This Argument?

The strongest case against me is that participation is already rising quickly. NGX data reported by allAfrica show domestic turnover of ₦10.68 trillion for January to July 2026, up about 126% from ₦4.73 trillion in 2025. Domestic institutions traded ₦6.71 trillion, up about 145%, and retail investors ₦3.97 trillion, up about 100%. Foreign investors traded ₦1.29 trillion, or 10.79% of the ₦11.98 trillion total. By my calculation, domestic institutions accounted for about 63% of domestic turnover. Pension fund equity holdings rose about 65% between December and April, and the market's capitalisation reached ₦158.326 trillion at the end of July.

I concede the direction. Institutional demand is arriving, and my argument is not that institutions are absent. It is that rising demand into a small investable supply raises prices before it raises depth, and the data I have cannot separate repricing from deepening, because I have not found published spread or market-depth measures. Turnover is also a flow. Durability is about whether the flow holds when prices fall. And part of the capital arriving may be benchmark-driven rather than conviction-driven, a distinction the J.P. Morgan index analysis draws: funds tracking an index must hold its constituents in proportion regardless of their view of credit quality, which makes that capital sticky but undiscriminating.

This is the falsifiable part of my claim. If institutional participation continues to rise through a down-cycle, and investable float grows alongside it, the argument weakens.

Where This Argument Does Not Apply

I am not arguing that listings are bad. An offering that places a meaningful share of a company in public hands adds exactly the supply this argument says is scarce. Nor does the argument concern the mechanics of index inclusion, which the First HoldCo pillar covers, or detailed profiles of individual owners, or the longer-run scenarios for how African conglomerates may become institutional assets, which belong to a separate node. The claim is narrow: the binding constraint on depth in the Nigerian market is the quality of demand and the size of investable float, not the number of companies on the board.

Why This Matters for Pension Regulators and Capital Allocators

For regulators, the implication is that the metrics for success should change. A count of listings or a headline market capitalisation measures supply and size. The measures that track depth are investable float, the share of equity held by institutions over multi-year horizons, and how holders engage with issuers. If I were setting priorities, I would put float thresholds and stewardship expectations ahead of listing targets, though that is my opinion and not a finding. The reason is sequence. Raising equity allocation limits before float and stewardship improve pushes more money toward the same small set of tradable shares, which lifts prices without adding the supply or the engagement that would make the holdings durable.

For allocators, the consequence is that capitalisation can overstate what is buyable. A portfolio sized against the headline index inherits the thin float of its largest constituents, and the cost shows up in exit liquidity when selling is hardest. The economic consequence of the supply diagnosis is a market that looks larger each year while the share of it that long-term capital can own barely moves.

Conclusion

The market does not need more companies to prove it is deep. It needs institutions whose capital is durable, whose holders can engage with issuers, and a float large enough for them to own. The evidence from Nigeria supports the direction of this claim and leaves its strongest test, a sustained downturn, still to come. Until then, depth should be measured by what long-term capital can actually buy, not by how many companies are listed.
