Nigeria’s equity market has been dealt a potentially significant setback after global index provider FTSE Russell placed the country’s planned reclassification to Frontier Market status under further review, citing concerns that the Nigerian Exchange’s (NGX) transition to a T+1 settlement cycle could effectively force foreign investors to prefund their trades.
The decision raises fresh questions about the sustainability of the Nigerian stock market’s recent rally and its ability to attract the foreign portfolio investment (FPI) flows that are widely regarded as critical to improving market liquidity, price discovery and long-term capital formation.
According to FTSE Russell, the accelerated settlement cycle may undermine one of its core Quality of Markets criteria—Settlement Cycle/Delivery versus Payment (DvP)—because international institutional investors could be required to have cash available before executing trades, effectively turning Nigeria into a prefunded market.
The review comes barely two months after FTSE Russell had confirmed Nigeria’s planned upgrade to Frontier Market status, effective September 21, 2026, following the country’s earlier migration from T+3 to T+2 settlement, a move that aligned the market more closely with international standards.
However, Nigeria proceeded to shorten settlement further to T+1 on June 1, prompting FTSE Russell to reopen its assessment.
Market analysts warn that the implications could extend far beyond the technical issue of settlement timelines.
Foreign portfolio investors remain a major source of liquidity on the Nigerian Exchange, particularly for large-cap banking, telecommunications and industrial stocks that dominate market capitalization.
While domestic institutional investors have become increasingly active over the past two years, FPIs continue to play an outsized role in driving daily turnover, supporting price discovery and providing the liquidity needed by global asset managers.
The timing of FTSE Russell’s review is particularly significant because it comes after one of the strongest rallies in the history of the Nigerian Exchange (NGX). The benchmark NGX All-Share Index (ASI) ended 2025 at 155,613.03 points, delivering an annual return of 51.19 per cent, while total market capitalisation climbed to about N99.38 trillion, up from roughly N66.23 trillion at the end of 2024, representing an increase of approximately N33.15 trillion, or about 50 per cent. The rally was driven by improving corporate earnings, banking recapitalisation, macroeconomic reforms and a gradual return of foreign investor confidence.
The bullish momentum carried into 2026, with the market crossing the historic N100 trillion capitalisation mark in January and reaching over N129 trillion by the end of the first quarter. By the end of March, the NGX ASI had surged to 201,287.78 points, representing a 29.35 per cent year-to-date gain, while market capitalisation had expanded by about N29.83 trillion, or 30 per cent, from N99.38 trillion at the beginning of the year to N129.21 trillion.
Analysts say that makes the FTSE Russell decision particularly consequential. The market’s remarkable gains have been underpinned by renewed optimism over Nigeria’s reform programme and expectations of increased foreign participation following the country’s planned return to the FTSE Frontier Market Index. Any delay or reversal could weaken foreign portfolio inflows, reduce trading liquidity and increase volatility, potentially interrupting the momentum that has made the NGX one of Africa’s best-performing equity markets over the past 18 months.
Analysts note that any development that discourages international investors could reduce market depth, widen bid-offer spreads and weaken investor confidence at a time when Nigerian equities have attracted renewed global attention.
Why T+1 matters
Settlement cycles determine the number of business days between executing a trade and completing payment and delivery of securities.
Globally, several advanced markets, including the United States, have migrated to T+1, largely because they possess sophisticated market infrastructure, deep foreign exchange liquidity and seamless coordination among custodians, brokers and clearing houses.
However, FTSE Russell’s concern is not the T+1 framework itself but whether foreign investors can complete both the equity and foreign exchange legs of transactions within one business day without having to deposit funds in advance.
Published FTSE Russell market classification criteria state that markets requiring mandatory prefunding are viewed less favourably because they increase operational costs and settlement risks for institutional investors.
Market participants argue that, under current Nigerian conditions, overseas investors may have little choice but to keep idle naira balances in local accounts before trading,effectively transferring settlement risk from the market infrastructure to investors’ balance sheets.
Broader implications
The FTSE review could have consequences beyond the immediate Frontier Market classification.
Global equity indices serve as benchmarks for trillions of dollars managed by passive and active investment funds.
Inclusion or continued membership often results in automatic capital inflows from index-tracking funds, while exclusion or delayed upgrades can reduce visibility and limit investment allocations.
Analysts say uncertainty over FTSE classification could also slow Nigeria’s longer-term ambitions of qualifying for inclusion in other influential global benchmarks such as those managed by MSCI, widely regarded as one of the world’s most important equity index providers.
Successful inclusion in major international indices generally lowers countries’ cost of capital by improving liquidity, expanding the investor base and increasing confidence in market accessibility.
Window for corrective action
FTSE Russell has indicated that it will continue monitoring developments before reaching a final decision later in August, leaving regulators with a narrow window to address concerns before the planned September implementation date.
Industry stakeholders have suggested several possible solutions, including providing optional settlement arrangements for foreign investors, introducing same-day foreign exchange facilities aligned with global custodian timelines, strengthening Delivery versus Payment mechanisms and improving engagement with international custodians and institutional investors.
Many market participants argue that while Nigeria’s ambition to modernise its capital market is commendable, reforms must be carefully sequenced to ensure market infrastructure evolves alongside settlement timelines.
For Nigeria, whose capital market has enjoyed a prolonged bullish run supported by renewed foreign interest, the outcome of FTSE Russell’s review could prove pivotal.
A favourable decision would reinforce investor confidence and strengthen the country’s integration into global capital markets. Conversely, failure to address the concerns could slow foreign portfolio inflows, reduce market liquidity and weaken momentum just as Nigeria seeks to position its stock market as one of Africa’s leading investment destinations.
