Stock Market Impact: The upgrade of Seplat Energy PLC’s long‑term issuer rating from B to B+ and the parallel upgrade of Nigeria’s sovereign rating to B are likely to lift Seplat’s share price and improve sentiment for oil‑and‑gas equities in the Nigerian market.
Listed Companies and Sectors: Seplat Energy PLC, a listed oil & gas exploration and production company, benefits from the rating action. S&P projects production of 135,000‑155,000 barrels of oil equivalent per day on average, net‑debt leverage of 0.5‑1.5×, and funds‑from‑operations to debt of 45‑60% across the cycle. The outlook remains stable, with expected improvement in credit metrics for 2026‑2027 assuming Brent crude at $100/barrel in 2026 and $75/barrel in 2027.
Investment Flows: The sovereign rating upgrade of Nigeria (foreign and local currency ratings to B on 15 May 2026 and country risk assessment to 5 on 19 May 2026) may attract additional foreign portfolio investment into Nigerian assets, including Seplat’s securities.
Interest Rates, Inflation, and Liquidity: No direct monetary policy changes are mentioned. S&P highlights Seplat’s policy of holding at least 70% of cash in hard currency, with at least 70% of that cash held offshore, indicating strong liquidity.
Fiscal or Monetary Policy: No specific fiscal or monetary measures are cited; the rating actions reflect Nigeria’s firming economic growth, commitment to reforms, and improved external position, including higher foreign‑exchange reserves.
