Nigeria has officially rejoined the FTSE Frontier Index Series after a three-year absence, buoyed by improved foreign-exchange liquidity and structural market enhancements.

The Asian Development Bank secured $2 billion through a 10-year global bond offering with a 4.625% coupon to fund investments in developing member countries.

Leadership from the Nigerian Exchange Group and the Central Securities Clearing System are in London to discuss index status concerns with FTSE Russell. The talks aim to address operational challenges international investors face following Nigeria's transition to a T+1 settlement cycle.
