What we track
10 series with anchored historical reference points going back to 2020. Each anchor below is recoverable from a named public source — NBS, CBN, AbokiFX, PropertyPro, or the operator's own published tariff.
Methodology
Between anchored dates we linearly interpolate. That's an approximation — actual prices don't move in straight lines — but it's honest about what we know and what we're estimating. As our daily snapshot archive (started May 23, 2026) accumulates, organic data points layer in alongside the anchors and interpolation gives way to actual observations.
- FX rates are parallel-market / market-rate equivalents (not official CBN window).
- Fuel uses the PPPRA cap pre-May 2023 and NBS bulletin averages thereafter.
- Cement uses Dangote's ex-factory price (the market-leader benchmark).
- Food uses NBS Selected Food Prices bulletin medians.
- Rent uses PropertyPro's half-yearly Lagos mainland averages.
- Where an anchor is missing for a year, we interpolate from the bracketing dates.
The inflation index, weekly.
When the cement, rice or USD line moves, the weekly digest leads with it — alongside what the official NBS CPI release said the same week.
