The market’s record close also came on the day Nigeria’s equities returned to FTSE Russell’s frontier-market classification, providing useful context without claiming that the reclassification alone caused Monday’s gains.

The record market valuation coincided with Nigeria’s formal return to frontier-market status in FTSE Russell’s global equity classification on September 21.
FTSE Russell had previously classified Nigeria as “unclassified” in 2023 amid foreign-exchange liquidity constraints and difficulties experienced by international investors seeking to repatriate funds.
The global index provider announced earlier in 2026 that Nigeria would return to frontier status following an assessment of improvements in market accessibility and foreign-exchange conditions.
