Nigeria's macroeconomic reform programme is delivering measurable results in May 2026, with all three major rating agencies upgrading the sovereign for the first time in over a decade and the NGX All-Share Index posting 127% year-on-year gains. However, the reform dividend remains uneven: inflation reversed its disinflationary trend in April, rising to 15.69% on fuel price shocks from the Middle East conflict, while a fiscal deficit equivalent to 70% of projected revenue raises sustainability questions ahead of the 2027 election cycle. The Central Bank holds its MPR at 26.5%, balancing naira stability against the cost of tight credit conditions for an economy where poverty is projected at 53.4%.
TL;DR
- Q4 2025 GDP growth hit 4.07% year-on-year; 2026 forecasts range 2.9%-4.6%
- Inflation climbed to 15.69% in April 2026 from 15.10% in January
- Central Bank holds MPR at 26.5% following February 50bps cut
- NGX All-Share Index up 127% year-on-year as of May 20
- S&P upgraded sovereign rating to B from B-, first upgrade in 14 years
Macro Overview
Nigeria's GDP expanded 4.07% year-on-year in Q4 2025, marking a strong close to the fiscal year as annualized growth exceeded 4% for 2025. The recovery was driven by higher crude oil production and stronger performance in dominant sectors, with agriculture contributing 25.67% to nominal GDP in Q4. Looking ahead, PwC projects 4.3% GDP growth for 2026, while scenarios range from 2.86% in the worst case to 4.6% in the best case, depending on exchange rate stability, oil output, and inflation trajectory.
Inflation rose to 15.69% in April 2026, reversing the 10-month disinflationary trend that pushed headline inflation to 15.10% in January. The uptick reflects fuel price shocks from the Middle East conflict, which elevated food and transport costs. Food inflation accelerated to 16.06% in April, undermining earlier optimism from single-digit food inflation of 8.89% recorded in January.
On external accounts, Nigeria's current account surplus expanded to 6.8% of GDP in 2024 from 1.3% in 2023, supported by stronger remittances and reduced refined fuel imports following higher local refining capacity. However, the fiscal position remains precarious: the 2026 budget proposes total expenditure of ₦58.47 trillion against projected revenue of ₦33.19 trillion, leaving a deficit of ₦25.27 trillion—equivalent to a deficit-to-revenue ratio of about 70%.
Monetary Policy
The Central Bank of Nigeria held its Monetary Policy Rate at 26.5% in May 2026, maintaining a restrictive stance after cutting rates by 50 basis points in February from 27%. Governor Olayemi Cardoso emphasized that a cautious and vigilant stance was needed to anchor inflation expectations, particularly after headline inflation climbed for a second month to 15.7% in April.
On currency dynamics, the naira strengthened to N1,373.34 per dollar on May 20, showing resilience amid reforms. Gross external reserves climbed to $49.49 billion as of May 15, 2026, providing more than nine months of import cover. The CBN's FX reforms have improved market liquidity, with average monthly FX turnover rising to approximately $8.6 billion in 2025, and April 2026 recording nearly $10 billion.
However, tight monetary conditions impose costs: the CBN's high interest-rate stance supports FX stability but weighs on growth, while borrowing costs remain elevated for businesses and households, with immediate relief limited as food prices and weak purchasing power persist.
Political Risk
President Bola Tinubu's administration, inaugurated in May 2023, has implemented sweeping reforms—fuel subsidy removal, FX unification, and tax overhauls—that have drawn both praise from international institutions and domestic criticism over cost-of-living pressures. Tinubu reaffirmed commitment to strengthening democratic institutions, stating the Electoral Act 2026 represents a collective national effort to deepen electoral integrity, though opposition parties have criticized the amendments.
Government stability appears intact, with Vice President Kashim Shettima stating the administration shifted focus from stabilization in 2025 to acceleration in 2026. However, institutions remain ineffective at protecting citizens from insecurity, economic recession, or inflation, while government revenues have declined and deficit spending has increased.
Security challenges persist: kidnapping, banditry, and insurgency continue to affect economic activity, food production, and internal movement. With fiscal deficits expected to average 3.1% of GDP in 2025-26 as spending pressures mount ahead of the 2027 general elections, and poverty projected at 53.4% in 2026, the administration faces mounting political pressures to deliver tangible benefits while maintaining reform discipline.
Equity Market
Nigeria's NSE All Share Index fell to 249,064 points on May 20, 2026, but remained up 127.21% year-on-year, continuing a remarkable rally. In 2025, the Nigerian Stock Exchange posted a robust 48.12% gain, outperforming regional peers. The benchmark NGX All-Share Index closed at 249,175.39, representing a year-to-date gain of 60.13% as of May 22.
The equity surge reflects strong performance in banking, consumer goods, and industrial stocks, supported by recent economic reforms including exchange rate stabilization, banking sector recapitalization, and fiscal consolidation. Market capitalization reached ₦159.7 trillion ($117 billion) in May 2026.
However, concerns linger: Nigeria's stock market has reached record levels, but concerns remain over market depth, bank valuations, and limited productive lending. Sector concentration in financials and the disconnect between equity performance and real economy conditions (high inflation, weak consumer purchasing power) pose valuation risks.
Investment Themes
Opportunities:
- Reform credibility gaining traction: Upgrades by Fitch, Moody's, and S&P send a strong signal that Nigeria is regaining macroeconomic credibility, potentially improving access to international capital markets
- FX market stabilization: Structural reforms including foreign exchange market liberalization and market-driven exchange rates have reduced volatility, supporting portfolio inflows
- Equity rally momentum: NGX up 127% year-on-year, with banking, consumer goods, and industrial sectors outperforming
- Oil sector upside: Oil production expected to average 1.5 million barrels per day in 2025, up from 1.34 mbpd in 2024, though still below pre-pandemic levels
Risks:
- Fiscal sustainability concerns: ₦25.27 trillion deficit in 2026 against revenues of ₦33.19 trillion raises debt trajectory worries; interest payments expected to consume 43% of government revenue in 2025
- Inflation volatility: Inflation rising to 15.69% in April due to Middle East conflict fuel shocks threatens reform gains
- Political cycle risks: Spending pressures mounting ahead of 2027 elections could derail fiscal consolidation
- Structural bottlenecks: Insecurity affecting food production, weak tax administration (one of the lowest tax-to-GDP ratios in Africa), and poverty at 53.4% in 2026
- Sovereign-bank linkage: Banking exposure to government securities exceeds 250% of core capital, creating systemic concentration risk
Sovereign Risk
Credit Ratings:
- S&P: Upgraded to B from B- with stable outlook in May 2026, marking Nigeria's first upgrade by S&P in 14 years
- Moody's: B3 with stable outlook (upgraded from Caa1 in May 2025)
- Fitch: B with stable outlook (upgraded from B- in April 2025)
All three agencies cite improving macroeconomic conditions, FX reforms, and stronger fiscal performance as upgrade rationale. However, S&P notes Nigeria still faces significant structural challenges including inflation, poverty, unemployment, and security pressures.
CDS Spreads & Outlook: While specific CDS spread data for May 2026 was not directly available in search results, sovereign bond yields show improving sentiment: Nigeria's 10-year government bond yield held at 14.96% on May 19, 2026, remaining 4.93 points lower than a year ago. The rating upgrades have likely compressed credit default swap spreads, though structural linkage between sovereign and banking sector risk remains a key vulnerability, with bank exposures exceeding 250% of capital tied to government securities.
The outlook remains stable but conditional: reversing current reforms or adopting expansionary fiscal policies could negatively affect future ratings performance, while persistent inflation, weak governance, and low revenue mobilization continue to undermine Nigeria's credit profile.

FAQ
Q: Is Nigeria's inflation decline sustainable given recent upticks?
A: Early indicators suggest Nigeria is trending toward the best-case scenario of 14.27% inflation by year-end, relying on an MPR averaging 24.5% and a naira at ₦1,300/$. However, fuel price shocks from the Middle East conflict have pushed inflation back to 15.69% in April, and achieving the best case hinges on sustained oil production, exchange rate stability, and mitigating climate and security shocks. The path remains promising but vulnerable to external shocks and domestic policy execution.
Q: How significant are the sovereign rating upgrades for market access?
A: The upgrades are highly consequential. Fitch, Moody's, and S&P upgrades send a strong signal to global investors that Nigeria is regaining macroeconomic credibility, and sovereign rating upgrades often reduce borrowing costs for governments and improve access to international capital markets. Bank and corporate ratings are typically capped at sovereign level, so upgrades trigger corresponding improvements in Nigerian bank ratings, opening the door to lower borrowing costs and broader investor interest. However, implementation risk remains: reversing reforms could quickly erode these gains.
Q: What are the biggest risks to Nigeria's investment case in H2 2026?
A: Three interconnected risks dominate: (1) Fiscal sustainability—the ₦25.27 trillion deficit and 70% deficit-to-revenue ratio raise concerns about debt trajectory, especially with interest payments consuming 43% of revenue; (2) Political cycle pressures—spending pressures ahead of 2027 elections could derail fiscal consolidation; (3) Inflation resurgence—rising inflation from fuel shocks threatens to undermine CBN credibility and consumer purchasing power. Structural issues—insecurity affecting food production and weak tax administration—compound these cyclical risks.
