Nigeria H1 2026: The Stabilisation Report

H1 2026 is the first six-month period since 2021 where Nigeria’s macro story can be told without the words “freefall,” “crisis,” or “emergency.” That is not a bullish call. It is a data-driven observation, and like every observation in this brief, it comes with its sources and its caveats. Here is what the canonical figures show, where they agree, and where they quietly diverge.

The headline: stabilisation, not expansion

Five numbers define the first half of 2026:

The narrative: growth is running slightly above the historical median (≈3.4% over 2010–2024). Inflation has fallen sharply — from a 34.8% peak on the rebased series (December 2024) to 15.93% in May 2026. The naira has held a ₦1,330–₦1,520/$ trading band for six months, the narrowest since the June 2023 managed float. Reserves reached $51.04bn as of June 18, the highest level since January 2009. That is the floor. What follows is what the floor does not fix.

The FAAC record — and what it conceals

FAAC distributed ₦2,036bn in March 2026 — back above ₦2 trillion, though below August 2025’s ₦2,225bn high. April (₦2,257bn) and May (₦2,300bn) then set new records. FAAC first cleared ₦2 trillion on July 2025 revenue and stayed above it through October. The step-up is real: the drivers are higher oil revenue (improved NNPCL remittances plus naira-denominated valuation gains from FX translation) and improved non-oil tax collection.

What it conceals: the fiscal-stress composite: Composite scores are being recomputed on actual data (17 Oct 2026). Nigeria’s total public debt was ₦159.3tn at the end of 2025 (DMO), and debt service took 76.7% of FGN retained revenue in January–September 2025 (Budget Office). A record FAAC month adds to the inflow side; it does not reduce the outflow side. The structural constraint has not moved. At LGA resolution (all 774 councils, state observed, LGA apportioned), the distribution is extreme — the top decile receives allocations multiple times larger than the bottom decile, which determines which councils can fund basic service delivery and which cannot. This is the evidence layer most Nigeria analyses skip. ONYX tracks it at every level.

The capital inflow story — strong headline, fragile composition

Capital importation hit $10.37bn in Q1 2026 — up 83.8% year-on-year, above the $8.49bn peak of Q1 2019. The composition is what matters: portfolio investment was 95.1% of total inflows; foreign direct investment just 1.3%.

Portfolio money responds to interest-rate differentials. At an MPR of 26.5% and a relatively stable naira, Nigeria’s real policy rate (≈10.8%, deflated against April CPI) is competitive with comparable EM debt. That is why the money came in. It is also why it can leave. FDI responds to the operating environment — infrastructure, energy cost, regulatory predictability. At 1.3% of inflows, the productive-capital story is not yet in the data. This is not cause for pessimism; it is cause for precision.

Reconciliation receipt: the inflation number you’re comparing wrong

Nigeria rebased its Consumer Price Index in 2024, shifting the base year from 2009=100 to 2024=100. Under the old base, the December 2024 print was often quoted as “34.8%.” Any year-on-year comparison that mixes pre- and post-rebase prints produces a false picture of the disinflation path. The rule: compare rebased figures to rebased figures. Several Nigerian aggregators still publish the old series alongside the new without flagging the discontinuity.

ONYX carries the rebased CPI (2024=100) from 1995 onwards, back-converted from NBS publications. When a source disagrees, we retain the alternate as a superseded record; the canonical value we serve is the NBS primary, rebased, with the period clearly marked. The current read: 15.93% (May 2026, rebased basis).

The PMI break — signal or noise?

Nigeria’s Stanbic IBTC PMI dipped to 49.4 in April 2026 — below the 50-point threshold for the first time in sixteen months. The drag came from input costs and supplier delivery times, consistent with a global supply-side squeeze rather than domestic demand collapse: new orders held; output expectations stayed above 50. The answer arrived quickly — the May 2026 PMI rebounded to 54.1, a nine-month high. The April contraction was a one-month blip, not the start of a trend.

Composite indices — H1 2026 mid-year read

All three ONYX composite indices update on every data ingest. Scores below are the 2025 baselines from the composite run of 9 Jun 2026; the live index on /today is recomputed as components are revised, with 90% confidence intervals from Monte Carlo sensitivity (5,000 draws, Dirichlet weight perturbation):

Composite scores are being recomputed on actual data (17 Oct 2026). One-line H1 read: the macro floor is in; the structural ceiling has not lifted.

What to watch in H2 2026

Five variables will determine whether stabilisation converts to sustainable expansion: (1) the monthly PMI trajectory — one sub-50 reading is a flag, two consecutive is a trend; (2) capital-importation composition in Q2 — whether portfolio inflows hold; (3) the debt-service trajectory against the FGN 2026 revenue assumptions; (4) the FAAC revenue trend — April (₦2.257trn) and May (₦2.300trn) both set records above ₦2trn, but FAAC also held above ₦2trn from July to October 2025 and then fell back, so the run alone does not prove the trend is structural, with June revenue due in the ~Jul 10 communiqué; and (5) monetary policy inflection — the CBN has held the MPR at 26.5% since March, and the first cut will be the most significant macro signal of the year.

Every figure here shows its receipts

Every number above carries its source, period, and capture method in the ONYX platform. When sources disagreed — and for Nigeria data they frequently do — we resolved against the primary print and kept the alternates as a dated audit trail.

Correction, 17 October 2026. An earlier version of this article said federal debt service takes about 40% of FGN retained revenue. That figure had no source, and it was wrong. The Budget Office’s budget implementation reports put debt service, including the sinking fund, at 76.7% of FGN retained revenue (excluding government-owned enterprises) for January to September 2025: ₦12.63trn against ₦16.48trn. For 2024, the last full year, it was 63.5% (provisional). It also said March 2026 was the first month FAAC distributed more than ₦2 trillion. On ONYX’s series, FAAC first cleared ₦2 trillion on July 2025 revenue, and August 2025’s ₦2,225bn stood as the high until April 2026. The text above has been corrected.
