J.P. Morgan adds Nigerian government bonds to GBI‑EM Edge; $17.47bn eligible, 7.4% country weight

On September 14, 2026 J.P. Morgan announced inclusion of Federal Government of Nigeria (FGN) local‑currency bonds in its newly created Global Bond Index—Emerging Markets Edge, assigning a 7.40% country weighting and identifying $17.47bn of eligible FGN instruments across 16 bonds, reopening passive index demand for Nigerian local debt.

Index inclusion mechanically creates passive demand from funds tracking the GBI‑EM Edge. That demand is most likely to target onshore liquid benchmarks and long‑dated maturities, which could exert downward pressure on onshore yields, deepen local secondary liquidity, and feed through to reduced foreign‑currency refinancing premia for Nigeria. The effect on FGN Eurobonds is indirect and concentrated at the long end.
