The defining act
The decade of borrowing
Buhari inherited a balance sheet rocked by the 2014 oil price collapse and chose to plug the gap with debt. Eurobonds, China-Exim loans, IMF emergency credit, and aggressive CBN ways-and-means financing pushed external debt from $45 billion to $103 billion in seven years. Gross government debt as a share of GDP doubled from 15% to 30%. Annual debt service tripled. By 2022, debt service consumed an estimated about 96% of federal revenue (per DMO and Finance Ministry data analyzed by BudgIT). The fiscal squeeze that defined the 2023 election was, in large part, the bill for these eight years.
The economy

$493B → $503B
+$10B over 8 years. 0.3% CAGR, the slowest sustained growth of any modern Nigerian president. Two recessions: 2016 (oil price crash) and 2020 (COVID).
GDP per capita
$2,586 → $2,281
−$305 per citizen. The only Fourth Republic administration where Nigerians ended up poorer than they began, on average.
Agriculture
+22.9%
3.0% CAGR. Anchor Borrowers programme expanded smallholder credit. Agricultural lending visibly rose, though productivity gains modest.
Manufacturing
−10.7%
−1.6% CAGR. Sector contracted in real terms over the tenure. FX rationing and import restrictions hurt input-dependent producers.
Power access
+15.2%
2.0% CAGR. One of the few sustained positive trends, share of population with electricity rose from about 52% to about 60%.
Inflation
−41.0%
Headline metric reduction. But this is partly artefact, chronic FX shortages and parallel-market premium meant CPI understated lived cost-of-living pain.

What he left behind
Legacy
01
$58 billion in new external debt. External debt nearly tripled. Annual debt service climbed from $2.4B (2014) to $9.7B (2023). The bill is now an inheritance for every subsequent administration.
02
Two recessions in eight years. 2016 (oil price crash, $44/barrel) and 2020 (COVID-19). First multiple-recession era for Nigeria since the 1980s.
03
The first defeated-incumbent election (2015). Buhari's 4th attempt at the presidency succeeded. Set the democratic precedent, Jonathan conceded peacefully, that defined the Fourth Republic's maturity.
04
Border closure (Aug 2019, Dec 2020). Closed all land borders to halt rice and other smuggling. Domestic rice prices spiked. Effective on some smuggling, painful on consumers and ECOWAS neighbours.
05
Naira redesign (October 2022). CBN announced replacement of N200, N500, N1,000 notes with weeks of notice. Massive cash crunch through Q1 2023. Affected the 2023 election turnout.
06
#EndSARS (October 2020). Mass youth protests against police brutality. Lekki tollgate incident October 20. Largest civic mobilization since the Fourth Republic began.
