Two years ago, the idea of Nigeria ranking among the world’s top five best-performing equity markets would have seemed optimistic at best, delusional at worst. The naira had just been floated and was in freefall. Inflation was at a 28-year high. Foreign investors were pulling capital out of Nigerian assets as fast as the system would let them. The NGX All-Share Index, despite its nominal naira gains, was delivering negative returns in dollar terms to any offshore investor unfortunate enough to be holding Nigerian equities.
Fast forward to 2026 and the story has changed dramatically. In 2025, the NGX All-Share Index posted a full-year return of 51.19 percent, one of the strongest performances of any major equity market on earth. Total annual turnover on the Nigerian Exchange hit a record ₦11.23 trillion, more than double the ₦5.59 trillion of 2024. Foreign investor transactions reached $1.97 billion, the highest in 19 years. And in March 2026 alone, foreign transactions jumped 107.74 percent month-on-month to $215 million.
This is not a bubble. It is not hype. It is the result of a specific set of reforms, executed under difficult conditions, that have genuinely changed the risk profile of Nigerian equities for global investors. Understanding what drove the return and what could reverse it is essential for anyone with exposure to or interest in Nigeria’s capital market.
“The NGX All-Share Index rose 136% between 2023 and 2025. Foreign transactions hit $1.97 billion in 2025, the highest in 19 years. Nigeria’s equity market is no longer just a story of potential. It is a story of delivery.”

Where Nigeria Was: The Years Foreign Investors Left
To appreciate how significant the return of foreign capital is, you need to understand how badly Nigeria’s capital market lost international confidence between 2015 and 2023.
The rot began with the CBN’s multiple exchange rate regime, a system that maintained an artificial official rate while a parallel market ran at a dramatically different price. For foreign portfolio investors, this was an existential problem. They could bring dollars into Nigeria at the official rate, buy equities, watch those equities appreciate and then find themselves unable to repatriate their profits at the same rate they came in at. The FX backlog at one point reportedly exceeded $7 billion; billions of dollars of foreign capital trapped in Nigeria, unable to exit. Once burned, institutional investors do not forget easily.
On top of the FX dysfunction, Nigeria was added to the Financial Action Task Force (FATF) grey list in February 2023, a designation that flagged strategic deficiencies in the country’s anti-money-laundering and counter-terrorism-financing framework. According to an IMF study, grey-listing reduces capital inflows by an average of 7.6 percent of GDP across affected countries, largely due to higher compliance costs and de-risking behaviour from global banks. For correspondent banking relationships, the plumbing that connects Nigerian financial institutions to the global banking system, the grey listing added friction, cost, and reputational risk to every international transaction.
The result was predictable. Foreign participation in NGX trading, which had historically accounted for 40 to 50 percent of activity, collapsed to single digits. Pension funds, sovereign wealth funds, and institutional asset managers across Europe and North America quietly removed Nigeria from their frontier market allocations. The domestic investor base pension funds, insurance companies, and retail investors had to carry the market alone.
What Changed: The Reform Stack That Rebuilt Confidence
The return of foreign investors to Nigerian equities is not the result of a single policy change. It is the cumulative effect of what analysts are calling a reform stack, a series of interconnected changes across monetary policy, fiscal management, market regulation, and international compliance that together have shifted Nigeria’s risk profile from unacceptable to investable.
1. Foreign Exchange Liberalisation
The single most important reform for foreign portfolio investors was the unification and liberalisation of the foreign exchange market in June 2023. By ending the multiple exchange rate system and allowing the naira to find its market level, President Tinubu’s administration resolved the repatriation problem that had trapped billions of dollars of foreign capital. Investors who had been burned by the old system could now, for the first time in years, be confident that the dollars they brought in could be taken out at a transparent, market-determined rate.
The initial shock was severe, the naira collapsed from ₦450 to over ₦1,500 against the dollar in the space of months. But for foreign investors looking forward rather than back, a volatile but transparent market is far preferable to a stable but rigged one. Once the new FX regime demonstrated staying power, the re-entry began.
2. FATF Grey List Removal — October 2025
On October 24, 2025, at the FATF Plenary in Paris, Nigeria was officially removed from the grey list alongside South Africa, Mozambique, and Burkina Faso. This was not a gift. It was the result of nearly three years of sustained institutional reform: new anti-money-laundering legislation, operationalisation of a beneficial ownership register, strengthened intelligence sharing between law enforcement agencies, and a 19-point action plan executed under the coordination of the Nigerian Financial Intelligence Unit.
The practical significance for capital markets is immediate and measurable. Grey list removal means global banks no longer need to apply enhanced due diligence to every transaction involving Nigeria. Correspondent banking relationships become cheaper and easier to maintain. Compliance costs for international investors fall. And the reputational signal, that Nigeria’s financial system is now considered to meet global standards changes the conversation in investment committee rooms in London, New York, and Singapore. Moody’s upgraded Nigeria’s long-term foreign-currency issuer rating from Caa1 to B3 in May 2025, citing improved fiscal position and demonstrated commitment to reform. The grey list removal added further momentum to that re-rating.
3. The Investments and Securities Act (ISA) 2025
The ISA 2025 is Nigeria’s most significant capital market legislation in nearly two decades. It replaces the 2007 Act and comprehensively modernises the regulatory framework governing securities, investment funds, digital assets, and market participants.
For foreign investors, three elements are particularly significant. First, ISA 2025 introduces enhanced investor protection including statutory rights for investors to rescind unauthorised foreign investment products and stricter disclosure requirements for fund offering materials. Second, it gives private equity and venture capital funds express legal authority to raise capital publicly, aligning Nigeria with international fund structures and opening a new channel for institutional capital. Third, and most futuristically, ISA 2025 provides regulatory clarity on digital and virtual assets recognising them as securities where applicable and creating a supervised framework for digital finance that reduces the wild-west risk perception that had previously deterred institutional investors from Nigeria’s fintech-adjacent capital markets.
The SEC Director-General Emomotimi Agama described the Act as a ‘comprehensive reform agenda’ designed to position Nigeria’s capital market for global competitiveness. The NGX Group Chairman called it a ‘bold statement of intent.’ The market agreed: trading volumes and foreign participation both accelerated in the months after the Act came into force.
4. Monetary Tightening and Yield Attraction
Nigeria’s Central Bank raised interest rates aggressively through 2024 and into 2025, pushing the benchmark Monetary Policy Rate to 27.5 percent at its peak. While this was painful for borrowers and businesses, it had a specific and powerful effect on foreign portfolio investors: it made Nigerian fixed-income assets, treasury bills, bonds extraordinarily attractive on a yield basis.
Global investors chasing yield in an environment where US rates were declining found Nigeria’s double-digit real yields compelling. The inflow of portfolio capital into fixed-income assets provided foreign currency liquidity that stabilised the naira and built confidence that the FX market could absorb significant inflows and outflows. That confidence, the belief that you can get your money out is the foundation on which equity market participation is built.
The Market Performance: What the Numbers Show
The NGX All-Share Index rose approximately 136 percent between 2023 and 2025. To contextualise that: the S&P 500 returned roughly 50 percent over the same period. The FTSE 100 returned around 15 percent. Nigeria’s equity market, measured in naira, was one of the best-performing in the world.
In 2025 specifically, the NGX ranked fifth among the world’s top-performing stock exchanges and fourth in Africa, according to the Federal Ministry of Industry, Trade and Investment. Total transactions more than doubled from ₦5.59 trillion in 2024 to ₦11.23 trillion in 2025. For the first time in several years, Nigeria recorded a net positive foreign capital flow meaning foreign inflows exceeded outflows. That is a structural signal, not a statistical fluke.
The Q1 2026 data confirms the trend is continuing. Foreign inflows rose 78 percent year-on-year to ₦393.68 billion. Foreign transactions in March 2026 alone more than doubled compared to February $215 million in a single month. Total market transactions in Q1 2026 reached $3.08 billion, an 85.9 percent increase from the same period in 2025.
The caveat and it is an important one is that outflows are also rising. Foreign outflows in Q1 2026 climbed 31.2 percent to ₦420.37 billion. This means Nigeria is still experiencing slight net outflows even as gross inflows surge. Investors are returning, but they are also actively taking profits and rebalancing. This is not the long-term, patient capital of infrastructure investors or strategic FDI. It is the fluid, opportunistic capital of portfolio managers who are constructive on Nigeria but not yet fully committed.
“Foreign inflows surged 78% in Q1 2026. But outflows also rose 31.2%. Investors are returning but they’re keeping one hand on the exit. The trust is rebuilding, but it is not yet complete.”
Who Is Buying and What Are They Buying
The foreign capital returning to Nigeria’s equity market is not distributed evenly across the exchange. It is concentrated in large, liquid, fundamentally strong companies primarily in banking, consumer goods, and telecoms that institutional investors can enter and exit at scale without moving the market against themselves.
Banking stocks have been among the biggest beneficiaries of the reform narrative, with several Tier 1 banks launching rights issues and public offers to meet the CBN’s recapitalisation requirements. These capital raises have attracted both domestic institutional investors and foreign strategic participants looking for exposure to Nigerian banking at what many analysts consider attractive valuations relative to peers across Africa and emerging markets.
MTN Nigeria and Airtel Africa, the two dominant telecoms players have also attracted sustained foreign interest as dollar-revenue earners with strong market positions and improving FX visibility. The NGX’s Banking ASI and its Consumer Goods Index have both outperformed the broader All-Share Index over the reform period.
What Could Stop the Recovery
The return of foreign investors to Nigerian equities is real and data-backed. It is also fragile, and the conditions that enabled it are not guaranteed to persist.
The four risks most cited by analysts and market participants are: first, inflation and interest rate trajectory, if the CBN is forced to cut rates faster than inflation falls, the yield attractiveness that drew in portfolio capital evaporates; second, FX stability, a sharp naira depreciation event would trigger immediate capital flight from investors still scarred by the 2015 to 2023 experience; third, security, a major escalation of insecurity in economically critical regions would damage the reform narrative that is currently driving sentiment; and fourth, election cycle risk — Nigeria’s next general election cycle will begin to loom larger from 2026 onward, and fiscal discipline historically loosens in pre-election years, creating macro risks that patient foreign capital monitors carefully.
Structural improvements are also still needed. Market depth remains limited, the NGX has relatively few listings compared to peer exchanges, and the pipeline of new IPOs has been slow despite the buoyant market conditions. Capital gains tax policy needs clarification. And the 80 percent local investor dominance of total trading means the market’s resilience still depends heavily on domestic institutional investors, pension funds and insurance companies whose mandates and risk appetite are constrained by regulation.
The Bottom Line
Nigeria’s equity market has earned back a portion of the credibility it spent a decade destroying. The FATF grey list removal, the ISA 2025, the FX unification, and the monetary tightening cycle together constitute the most coherent set of capital market reforms Nigeria has implemented in a generation. Foreign investors are noticing and returning, cautiously but measurably.
The 51 percent All-Share Index return in 2025, $1.97 billion in foreign transactions, the highest in 19 years. The 78 percent surge in foreign inflows in Q1 2026. These are not the numbers of a market being ignored. They are the numbers of a market being re-rated.
But the gap between portfolio re-rating and genuine long-term commitment remains wide. The money coming in is largely tactical chasing yield, exploiting cheap valuations, rotating into a market that the reform story has made temporarily attractive. Converting that into the patient, structural capital that builds companies, creates jobs, and transforms economies requires one thing above all else: consistency. Consistent policy. Consistent regulation. Consistent macro management.
Nigeria has a historic track record of starting reforms and not finishing them. The investors returning to the NGX in 2026 know this better than anyone. They are not betting that Nigeria has changed permanently. They are betting that the change is real enough, for long enough, to be worth the risk. Proving them right is now the most important economic task Nigeria faces.
