Nigeria has the scale. Ghana has the rerating story. The real question is not which market is bigger, but which risk premium investors are being paid to assume.

By Lord Fiifi Quayle

For years, any serious discussion about African capital markets would inevitably place Nigeria ahead of Ghana.

And, on one very important measure, that remains true.

Nigeria has the larger economy, the deeper capital market, greater trading liquidity, a broader universe of listed companies and a much larger institutional investor base. The Nigerian Exchange (NGX) is simply a different scale of market.

But 2026 is forcing investors to ask a more interesting question:

Is size still the most important determinant of opportunity?

I do not think it is.

The more useful question for investors today is:

Where is the greater compensation for the risk being assumed?

On that measure, the Ghana Stock Exchange (GSE) deserves considerably more attention than it has historically received.

The numbers have changed the conversation

Both markets have delivered extraordinary equity-market performances this year.

As of early August, the GSE Composite Index was up roughly 73% year-to-date, while the NGX All-Share Index was up about 58%. 

These are remarkable numbers by any standard.

But they also require interpretation.

A rising stock index does not automatically mean an economy has become fundamentally stronger. Equity markets price expectations, liquidity, earnings, interest rates, currency conditions and risk premiums. A market can rise because investors are becoming more optimistic about the future, even before that optimism is fully reflected in the underlying economy.

That is precisely why the Ghana–Nigeria comparison is so fascinating.

Ghana’s rally increasingly looks like part of a broader macro-risk repricing.

Nigeria’s rally looks more like a combination of earnings, liquidity, structural reform and market depth.

Those are different investment stories.

Nigeria: The case for scale

There is no need to manufacture an argument for Nigeria.

The case is obvious.

The NGX offers investors exposure to some of Africa’s most important corporate franchises across banking, telecommunications, cement, energy, consumer goods, industrials, insurance and technology.

Its scale matters.

For a large institutional investor, liquidity is not a luxury. It is an investment variable.

An asset that can generate a 20% return but cannot be exited efficiently can be less attractive than an asset generating a smaller return in a much deeper market.

That is one of Nigeria’s structural advantages.

The NGX’s market capitalisation reached approximately ₦158.3 trillion by the end of July, with the market generating approximately ₦58.9 trillion in investor gains during the first seven months of 2026, according to Nigerian market reporting. 

And Nigeria’s pipeline of corporate activity reinforces the argument.

The proposed listing of Dangote Refinery, reportedly targeting approximately $5 billion, would be a major event for the Nigerian capital market and potentially the largest IPO in Africa. 

This is what market depth looks like.

Nigeria can produce companies large enough to materially change the composition of the exchange.

Ghana cannot yet do that at the same frequency or scale.

For investors seeking breadth, liquidity and corporate scale, Nigeria remains the stronger market.

But Ghana is becoming a different kind of opportunity

The Ghana story is more subtle.

Ghana’s equity market is considerably smaller. That brings disadvantages: thinner liquidity, greater concentration and fewer investable names.

But it also creates something that large markets struggle to offer:

rerating potential.

The GSE has been one of Africa’s strongest-performing equity markets in 2026. The exchange’s own market reports show the extraordinary pace of the equity-market recovery, while recent market data place the GSE Composite Index around 15,200 points in early August. 

The question investors should therefore ask is not simply:

“Why has the GSE gone up?”

The better question is:

“What is the market beginning to price in?”

And the answer increasingly appears to be macroeconomic normalisation.

Lower inflation.

Improving fiscal credibility.

Greater confidence in debt sustainability.

Improved external-sector conditions.

Greater currency stability.

A changing interest-rate environment.

And, critically, the possibility that Ghana’s sovereign risk premium is declining.

This matters because equity valuations are not isolated from sovereign risk.

When investors become more confident in the sovereign, the cost of capital can fall. When the cost of capital falls, companies can be valued differently. When earnings expectations simultaneously improve, the effect can be powerful.

That is the mechanism of a sovereign-to-equity transmission channel.

This is where Ghana’s story becomes bigger than the GSE

I have long argued that African assets should not be evaluated solely through conventional debt-to-GDP ratios or headline economic growth.

Credibility matters.

Markets price not only what a government owes, but how investors perceive its ability and willingness to manage that obligation.

The same principle applies to equities.

A Ghanaian company operating in an environment where macroeconomic volatility is falling can experience a valuation rerating even without extraordinary changes in its underlying business.

The investor is effectively receiving two potential returns:

earnings growth + reduction in the risk premium.

That is a powerful combination.

It is also why Ghana’s equity performance should not be dismissed as merely a speculative rally.

There will certainly be speculation in a market that has risen this rapidly. There will also be profit-taking, valuation concerns and liquidity constraints.

But beneath the market movement is a more important question:

Is Ghana transitioning from a crisis-pricing regime into a normalisation regime?

If the answer is yes, the implications extend well beyond the GSE.

The problem with comparing the two markets

There is a temptation to say:

GSE +73% versus NGX +58%. Therefore Ghana wins.

That would be bad analysis.

The two indices are not directly comparable simply because both are expressed as index points or percentage returns.

The investor’s actual return depends on several variables:

Equity return + dividends + currency movement + inflation + liquidity + valuation.

A foreign investor therefore needs to ask a much harder question:

What was my return in hard currency?

A local-currency equity market can produce an extraordinary nominal return while generating a much smaller return for a dollar-based investor if the currency depreciates significantly.

Conversely, currency appreciation can amplify local equity returns for foreign investors.

This is why the next generation of African capital-market analysis must move beyond headline index performance.

At Africa Macro Intelligence, I would describe this as the difference between market performance and investor performance.

They are not always the same thing.

GSE’s weakness is also its opportunity

There is another uncomfortable truth.

Ghana’s market remains highly concentrated.

That means investors can be exposed to significant company-specific and liquidity risk. The GSE’s own market data have repeatedly demonstrated the importance of a relatively small number of large listed companies in overall trading activity. 

For a pension fund or global asset manager deploying hundreds of millions of dollars, this presents a genuine constraint.

Nigeria is simply easier to scale into.

But for a smaller institutional investor, family office, sophisticated private investor or long-term African investor, Ghana’s smaller size can be precisely what makes it interesting.

The market is less efficient.

And inefficient markets can sometimes contain greater mispricing.

That does not mean every Ghanaian stock is cheap.

It means the dispersion between price and fundamental value may be greater.

That is where active analysis becomes important.

So where should capital go?

My answer is deliberately not “Ghana” or “Nigeria.”

That would be too simplistic.

If you want scale, Nigeria wins.

The NGX offers greater liquidity, sectoral breadth and corporate depth.

If you want structural corporate growth, Nigeria remains compelling.

Its large domestic market and expanding corporate ecosystem provide a powerful investment universe.

If you are looking for a sovereign-risk rerating, Ghana is increasingly compelling.

The combination of macro stabilisation and equity-market repricing deserves attention.

If you are looking for frontier-market asymmetry, Ghana may offer the more interesting proposition.

But that comes with higher liquidity and concentration risk.

This distinction is critical.

Nigeria is primarily a scale story.

Ghana is increasingly a credibility-and-rerating story.

The bigger African investment question

There is a lesson here for Africa’s capital markets.

We should stop measuring the attractiveness of African markets solely by their size.

Some of the continent’s most interesting investment opportunities may emerge from countries undergoing transitions in credibility, institutions, macroeconomic stability and capital-market depth.

The next decade of African investing will not simply be about finding the biggest economy.

It will be about identifying where the market is mispricing the transition.

That is the investment thesis I find most compelling.

Nigeria has already demonstrated that Africa can build a large, liquid and increasingly sophisticated capital market.

Ghana now has the opportunity to demonstrate something different:

that restoring macroeconomic credibility can become an investable asset in its own right.

And if that happens, the GSE’s current performance may ultimately be remembered not as an isolated stock-market boom, but as an early signal of a broader repricing of Ghanaian risk.

My verdict

NGX is the deeper market.

GSE is the more concentrated market.

NGX offers greater liquidity.

GSE offers greater potential sensitivity to a decline in sovereign risk.

Nigeria offers scale.

Ghana offers rerating potential.

For investors willing to look beyond headline returns, the real contest is therefore not:

GSE versus NGX.

It is:

Scale versus asymmetry. Liquidity versus rerating. Corporate depth versus sovereign-risk repricing.

And that is a much more interesting investment debate.

The African investor of the future should not ask only, “Where is the biggest market?”

The better question is: “Where is the market underpricing the future?”
