Despite return to FTSE frontier index, local investors still dominate Nigeria’s stock market

Foreign investors staged a sharp comeback in Nigeria’s stock market last year. Equity turnover by foreigners on the Nigerian Exchange (NGX) roughly tripled in dollar terms in 2025 as a clutch of economic reforms rebuilt some of the confidence lost after the currency slump. It looked, briefly, like the start of something durable.

Yet, domestic investors have remained the dominant market force. They accounted for 78% of all market transactions during the year, while foreigners made up just 22%. Also, the momentum from 2025 has not carried through. Foreign participation on the exchange has fallen steadily this year, and foreign portfolio flows have been in net outflow every month from January to July, with more money leaving than coming in.

Look past the stock market entirely and the picture gets starker still. Of the $10.4 billion in capital that flowed into Nigeria in the first quarter of 2026, foreign investment in equities made up barely 1%. The rest went overwhelmingly into money-market instruments and bonds; dollars chasing yield, not shares.

It is against this backdrop that FTSE Russell is restoring Nigeria to its frontier-market index, effective September 21. The upgrade gives foreign investors a fresh reason to return. Whether many will take it is the bigger question. 

Foreign investors continue to shun Nigeria’s world-beating stocks 

Nigerians have financed their own stock market for most of its modern history. Back in 2007, domestic investors already accounted for roughly 85% of trading activity on the exchange. What has changed is not who dominates but by how much. The gap widened sharply as a currency crisis and a chronic shortage of dollars made the West African nation an increasingly difficult place for foreign investors to do business. 

The mechanics were straightforward. For years, Nigeria ran a multi-tiered exchange rate system, forcing investors to guess which one actually applied to them. The government unified the two in June 2023, floating the naira for the first time. But by then the damage was done. Reserves had fallen below $35 billion, where they stayed for the next two years.

In early 2024 however, the the nation’s apex bank said it had cleared $7 billion in outstanding FX backlog inherited from the previous administration.This was after FTSE Russell had downgraded Nigeria to “Unclassified” status in September 2023, citing market liquidity constraints.

Before the reclassification was confirmed late month, Africa’s most populous nation had been marked down by three of the world’s major index providers.

Despite the turmoil, domestic institutions had no such option to walk away. Pension funds and insurers are required by law to keep most of their investments in the local market, providing a steady, captive source of demand regardless of how foreigners swung. 

However, the same dysfunction that drove foreign capital away also kept the market small. As at the end of 2022, total market capitalisation stood at roughly ₦28.65 trillion, compared with ₦160 trillion at this year’s peak.

The market has grown in real terms too. Measured in dollars, its total value has nearly doubled post-unification, from $62.8 billion to about $116 billion in under four years. In July, Bloomberg named the NGX the best-performing equity market globally, as its dollar returns hit 67% year-to-date. 

Yet, foreign investors have continued to shun Nigerian stocks.

According to official market data, non-residents accounted for 12% of all transactions in H1 2026, down from 27% over the same period in 2025. By contrast, domestic investor participation increased to 88% from 73%. 

Nigeria is not alone in this. Major African stock markets have followed a similar pattern, although the NGX remains at the extreme end of the broader trend. 

Visibility vs inflow

FTSE Russell’s decision to restore Nigeria to Frontier Market status puts the country back on the radar of global investors. In a recent public notice, the index provider said the stock market now meets all five of its Quality of Markets criteria. This follows the clearance of FX arrears and the restored ability of international investors to repatriate capital without material delay.

From September 21, when the upgrade will kick-in, 31 Nigerian stocks will become eligible for the FTSE Frontier Index Series. In practice, passive funds tracking the relevant benchmarks will generally need to adjust their holdings to reflect Nigeria’s new index weightings. This could create a potential source of demand independent of investors’ views on individual stocks.

The largest beneficiaries are likely to be the country’s biggest banks and other heavyweight stocks such as MTN Nigeria and Airtel Africa. 

The upgrade comes as concerns over the bourse’s newly adopted T+1 settlement cycle have largely faded. Foreign custodians had worried that the shorter settlement period could force them to fund trades before execution. But FTSE said it had found no material funding problems since the new cycle took effect, allowing the reclassification to proceed after months of uncertainty.

Analysts are largely optimistic, if not uniformly so.

“FTSE’s acceptance of Nigeria’s new T+1 settlement system supports confidence in the country’s market infrastructure,” says Kazeem Adamu, a Lagos-based credit-risk expert. Cordros Securities has called the move “a catalyst for Nigeria’s capital market”, projecting $840 million to $1.04 billion in resulting inflows.

However, caution is still warranted. Reclassification does not compel index funds to buy Nigerian stocks immediately. Funds must first determine Nigeria’s actual index weighting and then rebalance according to their mandates. The benefits may also be concentrated: given the market’s heavy weighting towards a handful of large-cap companies, smaller and mid-cap stocks are unlikely to attract meaningful passive inflows.

Set against the NGX’s recent performance, even Cordros’s optimistic estimate looks modest. On July 8th alone, the exchange added roughly ₦3.45 trillion  in market value—about $2.4 billion at prevailing exchange rates—after Airtel Africa shares rose by 10%. That surge illustrates the scale of price movements the domestic market can generate, even without comparable foreign inflows. 

Investors nevertheless welcomed the announcement. The NGX ended an 11-session losing streak on the day of the news and gained a further 0.9% the following day.

The initial rally has since cooled, however, raising fresh doubts about whether the reclassification alone can sustain a bull market. 

FTSE’s decision is therefore best seen as a catalyst for access and visibility rather than a guarantee of capital inflows. The bigger test will be whether Nigeria can turn improved market infrastructure and renewed index eligibility into a lasting return of foreign investors. Its market regulators are already setting their sights on reinstatement to the MSCI and JPMorgan indices as they seek new ways to rebuild foreign investor confidence.

Meanwhile, S&P Dow Jones has placed the West African nation on a watch-list of its own, with a verdict due in 2027.

The hard part is not getting back on the list

Nigeria has fixed some of the problems that once made its stock market difficult for foreigners to navigate. The most obvious was access to dollars, following a sharp rise in reserves that has also helped strengthened the naira. In March, the CBN eased rules that had restricted the repatriation of oil companies’ export earnings, deepening dollar liquidity.

The improvements extend beyond the stockmarket. In October 2025, the Financial Action Task Force removed Nigeria from its grey list after concluding that the country had addressed deficiencies in its anti-money-laundering and counter-terrorist-financing regime. While this move, by itself will not make Nigerian shares more attractive, it removes another obstacle for international banks and investors.

On the macroeconomic front, the picture is also encouraging.  Gross Domestic Product growth accelerated to 4.43% year-on-year in the second quarter of 2026, while oil production rose to 1.72m barrels a day. S&P upgraded Nigeria’s sovereign rating in May, citing stronger oil production and an improved balance of payments.

Moody’s followed in August by raising its outlook to positive, pointing to higher reserves, stronger growth and better-functioning foreign-exchange markets.

Still, Africa’s most populous country is not an easy sell. The International Monetary Fund expects growth to hover around current levels in the near term—solid by recent standards, but underwhelming for an economy whose population is expanding rapidly. Inflation is still expected to end 2026 at around 17%. And for a dollar-based investor, a more functional FX market does not eliminate the risk of a falling naira.

Fiscal risks remain, too: S&P has warned that Nigeria’s narrow tax base and high debt-servicing costs leave its finances vulnerable to a reversal in reforms or weaker oil revenues.

That leaves the West African economy in an awkward middle ground. The barriers to getting money in, trading it and getting it back out have become less daunting. But foreign investors have plenty of alternatives, including frontier markets with more depth, lower inflation or more stable currencies. Nigeria therefore needs to demonstrate that its reforms will survive the next political cycle and that today’s improved FX liquidity and fiscal position are durable rather than the product of favourable oil prices.

The FTSE decision is evidence that the country has crossed an important threshold. It is not evidence that the journey is over.
