Adjust Forecast Parameters
The model explains approximately 74% of variation in Nigeria's GDP growth (2010–2025). Full-year 2025 GDP of 3.87% (NBS, Feb 27, 2026) is broadly consistent with model predictions given the reform dividend. The dominant drivers remain oil production (β=0.19) and oil price changes (β=0.08), confirming structural oil dependence. The FX Reform dummy captures the 2023 liberalisation premium (+0.72 pp). The negative inflation coefficient (−0.06) reflects demand-compression: every 10 pp increase in inflation reduces growth by ~0.6 pp. For 2026, the model implies 4.3–4.5% growth (consistent with BMI/Fitch 4.4%, World Bank 4.4%, PwC 4.3%) given: Brent ~$82/bbl, production rising to 1.84 mbpd, and inflation easing toward 12%.
Models oil price paths using: dS = μS·dt + σS·dW where μ = drift, σ = volatility, dW = Wiener process increment. Starting price: US$82/bbl (Brent, May 2026; post Iran-US Hormuz reopening Apr 18 — prices moderated from ~$103 peak). IMF WEO Apr 2026 projects $82.22/bbl average for 2026.
Estimated relationship: FAAC_oil (₦T) = 1.82 + 0.31 × Brent($/bbl) + 0.47 × Production(mbpd) + FX_rate_effect
Every $10 change in Brent crude ≈ ₦500bn change in FAAC oil revenues (at current production 1.84 mbpd, FX ₦1,376/$). 2026 budget benchmark: $64.85/bbl · 1.84 mbpd · ₦1,400/$.
At its peak (~$103/bbl in March 2026), the Iran conflict delivered approximately ₦6.8 trillion in additional oil revenue for Nigeria vs. the pre-conflict $67/bbl baseline (BMI/Fitch, Apr 2026). Iran formally reopened the Strait of Hormuz on April 18, 2026, triggering a price correction toward ~$82/bbl by May 2026 — still comfortably above the 2026 budget benchmark of $64.85/bbl. Nigeria's 2026 budget was also supplemented by ₦9 trillion (total: ₦67.4 trillion). The net windfall above budget benchmarks is estimated at ~₦3–4 trillion in additional oil receipts for the year, contingent on sustaining production at the NUPRC-announced 1.84 mbpd.
Primary Balance Condition: pb* = (r − g)/(1 + g) × d where pb = primary balance/GDP, r = real interest rate, g = real GDP growth, d = debt/GDP.
Nigeria stabilises debt if actual primary balance ≥ pb*. Adjust parameters to test sustainability.
Fiscal Parameters
Nigeria needs to close a fiscal gap of 3.5 pp of GDP to stabilise debt. This requires either revenue expansion, spending cuts, or GDP growth acceleration — or all three.
Debt/GDP Trajectory (10-Year Projection)
| Fiscal Metric | 2023 | 2024 | 2025 | 2026F |
|---|---|---|---|---|
| Revenue/GDP (%) | 7.8 | 8.1 | 8.5 | 9.5 |
| Expenditure/GDP (%) | 14.2 | 12.8 | 11.6 | 11.5 |
| Fiscal Deficit/GDP (%) | −6.4 | −4.7 | −3.1 | −3.5* |
| Debt Service/Revenue (%) | 73.5 | 62.4 | 49.5 | 42.0 |
| Capex/Total Spending (%) | 12.1 | 14.3 | 17.2 | 18.5 |
| FAAC (₦ Trillion) | 20.9 | 27.4 | 37.4 | 42–48† |
| * 2026 Budget supplemented by ₦9T → total ₦67.4T; deficit depends on oil revenue realisation. † Higher end if oil averages $82+/bbl and production holds at 1.84 mbpd. BMI/Fitch projects NGN 6.8T windfall vs. pre-conflict baseline. | ||||
Despite improvement, Nigeria's debt service-to-revenue ratio (49.5% in 2025) remains nearly double the IMF's 25–30% sustainability threshold. The 2026 budget supplemental (+₦9T) raises total expenditure to ₦67.4T, adding further pressure unless oil revenues at $82+/bbl and 1.84 mbpd are sustained. Every 1 pp reduction in the debt service ratio requires either ~₦374bn in new revenue or equivalent debt restructuring/refinancing.
Estimated model: π = α + β₁·π(-1) + β₂·E[π] + β₃·Oil + β₄·FX_depreciation + β₅·M2_growth + β₆·Output_gap + ε
Nigeria's inflation is primarily supply-side driven with significant FX pass-through (estimated at 0.31 for imported goods).
Inflation Driver Weights (Structural VAR Variance Decomposition)
| Driver | Contribution | Channel |
|---|---|---|
| FX Depreciation | 31.4% | Import costs |
| Food/Supply Shocks | 26.8% | Agriculture, insecurity |
| Fuel/Energy Costs | 18.9% | PMS prices, transport |
| Money Supply (M3) | 11.2% | Monetary expansion |
| Inflation Expectations | 7.6% | Expectation anchoring |
| Output Gap | 4.1% | Demand-pull (weak) |
Nigeria's inflation is 85%+ supply-side driven — FX pass-through + food shocks + fuel costs. This explains why the MPR (cut to 26.5% in Feb 2026, after peaking at 27.5%) has been imperfectly effective: demand-compression tools cannot resolve supply-side price pressures. Critically, March 2026's uptick (15.38%) was driven by transport (+16.9% YoY) and food (+14.31% YoY) — directly linked to the Middle East conflict's fuel shock — not monetary factors. The Hormuz reopening (Apr 18, 2026) should help moderate fuel-driven inflation in Q2–Q3 2026. CBN's 14.5–18.5% tolerance band is being respected, leaving room for further measured rate cuts in H2 2026.
Debt accumulation equation: d(t) = [(1 + r(t))/(1 + g(t))] × d(t-1) − pb(t)
where r = effective real interest rate on government debt, g = real GDP growth, pb = primary balance/GDP.

|---|---|---|---|---|
| 2025 (actual) | 39.8 | 39.8 | 39.8 | 39.8 |
| 2026F | 38.5 | 36.2 | 42.1 | 40.8 |
| 2027F | 37.4 | 33.1 | 46.5 | 43.2 |

| 2030F | 35.9 | 26.1 | 63.9 | 44.8 |
Nigeria's debt-to-GDP ratio remains moderate by regional standards (39.8% in 2025 vs. Ghana ~65%, Kenya ~70%), but the debt service-to-revenue ratio (49.5%) is the critical vulnerability — nearly double the IMF's 25–30% threshold. The revised bear scenario — triggered by an oil price collapse toward $50–60/bbl — pushes debt/GDP toward 64% by 2030. Revenue mobilisation (raising tax/GDP from 8.5% → 15%) and full PH Refinery + Dangote monetisation are the pivotal levers. The 2026 budget supplemental (₦9T) adds near-term fiscal pressure contingent on oil revenue delivery.
Three-phase scenario analysis for the Iran–US conflict impact on Nigeria's macro outcomes (2026–2027). Conflict started 28 February 2026. Iran formally declared the Strait of Hormuz open on 18 April 2026, triggering a price correction — Brent fell from ~$103/bbl (Mar peak) toward ~$82/bbl (May 2026). IMF WEO (Apr 2026) projects full-year average of $82.22/bbl; BMI/Fitch projects $78/bbl. Probabilities revised to reflect post-Hormuz dynamics.
| Variable | Current (May 2026) | S1: Truce Materialising | S2: Renewed Conflict | S3: Full Escalation |
|---|---|---|---|---|
| Brent Crude ($/bbl) | ~$82 (post-Hormuz) | $72–80 | $95–115 | $130–160 |

| GDP Growth 2026F | 4.4% (BMI/World Bank) | 4.0–4.2% | 4.4–4.6% | 3.8–4.0% |
| FAAC Oil Revenue (₦T) | ~₦38T (on track) | ₦32–35T | ₦44–50T | ₦52–60T |

| Fiscal Deficit/GDP | ~−2.8% (2026F) | −3.5% | −2.0% | −1.0% |
| Poverty Rate (2026) | 63% | 61% | 62% | 66%+ |
The Iran conflict created a paradox for Nigeria: the peak conflict scenario (Brent ~$103/bbl, March 2026) delivered an estimated ₦6.8 trillion windfall vs. the pre-conflict $67/bbl baseline (BMI/Fitch). However, the Hormuz reopening on April 18, 2026 has already begun to unwind this windfall — Brent has moderated toward $82/bbl by May 2026. Nigeria now faces the post-conflict arithmetic: at $82/bbl and 1.84 mbpd, revenues exceed the $64.85/bbl budget benchmark by ~$17/bbl (~₦3–4 trillion upside for the year), but far below the conflict peak. The optimal policy response was (and remains): deploy conflict windfall savings into the Sovereign Wealth Fund, front-load Dangote crude supply to 100%, and reduce the supplementary budget deficit exposure before any renewed conflict or oil price shock.

Impact at Selected Utilisation Rates
| Utilisation | Import Savings | CA Impact | GDP Add. | PMS Price Est. |
|---|---|---|---|---|
| 65% (current, NNPCL deal) | $13.0bn | +1.7% | +0.6pp | ₦950–1,050 |
| 75% | $15.0bn | +1.9% | +0.8pp | ₦850–950 |
| 90% | $18.0bn | +2.3% | +1.0pp | ₦750 |
| 100% (full, 650kbd) | $20.0bn | +2.6% | +1.2pp | ₦650 |
Full Dangote operation at 650,000 bpd would save ~$20bn annually in petrol imports — equivalent to ~4.5% of GDP. NNPCL crude compliance has improved from 26.9% (2025 avg) to ~65% (2026). However, 35% of potential import savings remain unrealised. Resolving the 100% crude supply commitment to Dangote remains the single most powerful economic lever available in 2026–2027, with potential PMS price reduction from ~₦1,000 to ₦650/litre at full utilisation.

Deepwater production (Bonga, Egina, Agogo, OPL 314) will increasingly dominate Nigeria's output mix, shifting from ~35% of total in 2022 to an estimated ~48% by 2028. Onshore volumes — driven by indigenous operators following the IOC divestiture wave — should stabilise around 700–800 kbd with improved security. Gas monetisation via NLNG Train 7 and the AKK pipeline represents the single largest untapped revenue lever over the medium term.
