Muhammadu Buhari concluded his presidency in May 2023 leaving a nation exhibiting signs of severe structural regression. Forensic analysis of macroeconomic data proves that this administration oversaw a period where nearly every primary indicator worsened. Gross Domestic Product growth rates failed to match population expansion.
This demographic misalignment birthed increased poverty headcount numbers. Data confirms 133 million Nigerians now live in multidimensional poverty. This statistic represents sixty-three percent of the total populace. Such figures contradict official narratives claiming success in agrarian reform or social welfare programs.
Realities on the ground display reduced purchasing power for average citizens.
Fiscal indiscipline defined these eight years. Central Bank financing reached illegal thresholds under the Ways and Means provision. Printing money without productivity backing caused hyperinflation. Consumer Price Index metrics spiraled upward uncontrollably. Food prices detached from earner reality. Families reduced consumption frequencies to survive.
Education budgets shrank in real terms while debt servicing costs ballooned. Revenue generation remained flat. Oil theft occurred at industrial scales daily. Security agencies failed to halt pipeline vandalism or secure export terminals. Consequently Nigeria lost its position as Africa's top crude producer temporarily during this era.
Foreign reserves depleted defending an indefensible currency valuation.
Exchange rate management utilized a disastrous multiple-window system. This arbitrage opportunity enriched political insiders while suffocating legitimate businesses. Manufacturers could not access foreign exchange for raw materials. Factories closed operations or relocated to neighboring jurisdictions.
Unemployment figures hit thirty-three percent officially before statistical collection stopped. Youth idleness fueled social unrest. The EndSARS protests highlighted deep frustration with police brutality and governance failure. State response involved kinetic force rather than dialogue or reform.
Trust between the governed and government evaporated completely.
Security architecture collapsed regionally. Boko Haram insurgency morphed into nationwide banditry. Northwest states experienced terror previously confined to the Northeast. Kidnapping became a lucrative criminal enterprise. Travelers abandoned roads for fear of abduction.
Rail infrastructure projects accumulated heavy Chinese loans but delivered compromised service. Terrorists attacked the Abuja-Kaduna train line successfully. Kuje Correctional Centre suffered a breach where high-profile terrorists escaped. Intelligence gathering yielded no actionable prevention.
Commander-in-Chief orders garnered no obedience from field operatives. Sovereignty appeared contested in rural zones where non-state actors collected taxes.
Corruption fighting served as a political weapon rather than an institutional cleansing. The Economic and Financial Crimes Commission targeted opposition figures selectively. Pardon power liberated convicted felons jailed for stealing billions. This action nullified the anti-corruption mantra entirely. Civil service morale plummeted.
nepotism determined appointments in key agencies. Federal Character principles were ignored consistently. Divisions along ethnic and religious lines widened dangerously. National cohesion fractured under perceived favoritism. Buhari retired leaving a polarized entity burdened by N77 trillion in public debt.

Legislative oversight failed to curb executive excesses. The National Assembly functioned as a rubber stamp for loan requests. Scrutiny regarding project viability was nonexistent. Ministries operated without fear of sanctions. Auditor General reports citing missing funds accumulated dust.
No high-ranking official faced prosecution for administrative negligence. Impunity reigned supreme across federal parastatals. Institutional checks effectively vanished. Governance became a personalized affair run by a cabal within the presidency.
Judiciary independence eroded systematically. Department of State Services agents raided judges' homes in midnight operations. A Chief Justice was removed unconstitutionally weeks before an election. Court orders were disobeyed routinely by executive bodies. Citizens lost hope in obtaining justice via legal channels. Rule of Law became Rule by Man.
This degradation of democratic norms remains a lasting legacy. History will judge this timeline harshly based on empirical evidence provided here.
Official records place the enlistment of Muhammadu Buhari into the Nigerian Military Training College in 1962. Mons Officer Cadet School in Aldershot provided subsequent instruction. Platoon Commander duties commenced in 1963 within the Second Infantry Battalion.
This officer participated actively during the July 1966 counter-coup which eliminated General Aguiyi-Ironsi. The Civil War saw him commanding the 4th Sector of the 1st Division. Troops under this specific command secured supply routes to Onitsha. By 1975 he acted as Governor for the North-Eastern State.
General Olusegun Obasanjo appointed this Daura native as Federal Commissioner for Petroleum and Natural Resources in 1976. That tenure birthed the Nigerian National Petroleum Corporation (NNPC) in 1977. Refineries located at Warri and Kaduna constitute tangible outputs from that era.
Scrutiny later arose regarding 2.8 billion dollars allegedly missing from Midland Bank accounts. A tribunal headed by Justice Ayo Irikefe found no proven theft yet noted accounting errors.
December 31 of 1983 marked the overthrow of Shehu Shagari. This Major General cited economic collapse plus corruption as justification. His Supreme Military Council suspended the 1979 Constitution immediately. Austerity measures followed. Borders closed. Imports ceased. The "War Against Indiscipline" demanded orderly conduct at bus stops.
Civil servants arriving late executed frog jumps. Decree Number 4 criminalized press reports deemed embarrassing to government officials. Two journalists faced jail time under these statutes.
General Ibrahim Babangida removed the regime in August 1985. Detention followed for the deposed leader until 1988. Sani Abacha later utilized him as Chairman for the Petroleum Trust Fund (PTF) starting 1994. PTF revenue funded roads plus hospitals across northern zones. Critics alleged regional bias regarding project allocation. Data confirms heavy investment towards infrastructure rehabilitation during those years.
Political ambitions surfaced in 2003. Defeats occurred against Obasanjo, Yar'Adua, then Jonathan. The All Progressives Congress formed a coalition which secured victory in 2015. History records this event as the first democratic transfer of power involving an incumbent defeat.
Economic indicators fluctuated wildly between 2015 and 2023. Two recessions struck the federation. Oil prices crashed in 2016. A global pandemic triggered another contraction in 2020. The administration closed land borders to boost local rice production. Food inflation surged regardless. Security forces battled Boko Haram in the northeast while banditry ravaged the northwest.
Fiscal metrics from the Central Bank reveal sharp deterioration. Public debt climbed from 12 trillion Naira in 2015 to 77 trillion Naira by May 2023. That figure includes Ways and Means advances. Unemployment rates tripled. The Naira lost significant value against foreign currencies. Anti-corruption efforts yielded recoveries of looted funds but convictions of high-profile political figures remained rare.

The presidency concluded with mixed assessments. Infrastructure projects like the Second Niger Bridge reached completion. Rail lines connected Lagos to Ibadan. Yet insecurity spread beyond the northeast. Kidnapping became an industry. Crude oil theft reduced output below OPEC quotas. Brain drain accelerated as professionals emigrated. The baton passed to Bola Ahmed Tinubu amid these conditions.
Governance under Muhammadu Buhari functioned as a statistical deviation from normative economic management. Data points collected between 2015 and 2023 reveal a trajectory of decline across every major development index. This analysis prioritizes raw numbers over political rhetoric to establish the factual density of administrative failure.
A primary indictment involves the illegal securitization of the "Ways and Means" advances. The Central Bank of Nigeria breached its own 2007 Act by lending the Federal Government N22.7 trillion. Section 38 of that Act caps such advances at five percent of the previous year's revenue.
Godwin Emefiele directed the apex bank to print currency far exceeding legal limits. This liquidity injection without productivity growth ignited hyperinflation which destroyed the purchasing power of the Naira.
Public debt records show another variance between executive promises and fiscal reality. The Debt Management Office reported a total liability profile of N12.12 trillion in June 2015. By May 2023 that figure swelled to N77 trillion. Servicing this obligation consumed 96 percent of government revenue in 2022.
Such expenditure left negligible funds for capital projects or health infrastructure. Corruption allegations surfaced regarding the Nigerian National Petroleum Corporation. The entity failed to remit dollars to the foreign reserve accounts for months. This starvation of the official window forced businesses towards the parallel market.
Consequently the exchange rate moved from N197 per USD to over N750.
Human rights violations present an equally dark ledger. The events of October 20 2020 at Lekki Toll Gate remain a stain on the democratic record. Peaceful protesters demanded an end to police brutality under the EndSARS banner. Military personnel from the 81st Division intervened with kinetic force. Live ammunition was discharged at unarmed citizens.
The administration initially denied military presence. Later they admitted soldiers were there but fired only blanks. Forensic evidence and hospital records contradicted these claims. A judicial panel subsequently labeled the event a massacre. No senior officer faced prosecution for these actions.
Censorship emerged as a tool for controlling narratives. On June 4 2021 authorities suspended Twitter operations within the federation. This directive followed the platform deleting a tweet by the President which threatened secessionists with civil war memories. Access remained blocked for 222 days.
NetBlocks estimated this action cost the economy N546 billion. Small businesses relying on social commerce suffered immense losses. The administration insisted the ban was about national security. Critics identified it as personal retaliation by a leader unaccustomed to digital accountability.
Security architecture collapsed in the North West. While the military focused on Boko Haram in the North East bandit gangs seized control of Zamfara and Katsina. These groups kidnapped thousands for ransom. The Abuja Kaduna train attack in March 2022 exemplified this intelligence failure. Terrorists mined the track and abducted passengers.
Hostages spent months in captivity while government negotiators appeared helpless. Citizens perceived a total absence of protection. The Global Terrorism Index ranked Nigeria among the most dangerous nations on Earth during this tenure.
Nepotism charges dogged appointments across security and revenue agencies. Critics noted a lopsided concentration of personnel from the President's region holding command positions. The Department of State Services and Customs Service saw leadership retention beyond statutory retirement ages.
This disregard for federal character principles alienated other zones. It fueled separatist agitations in the South East. Nnamdi Kanu remains in detention despite court orders for his release. The executive branch repeatedly disobeyed judicial pronouncements. This behavior signaled a breakdown in the rule of law.
Oil theft reached industrial proportions under this watch. Production fell below one million barrels per day at various points. Pipelines functioned as free dispense points for syndicates. Naval monitoring appeared nonexistent or complicit. The nation lost its status as Africa's top producer to Angola temporarily.
Revenues that should have stabilized the currency vanished into private pockets. A Tompolo led security contract later exposed illegal connection lines operating for years.

History records the tenure of Muhammadu Buhari as a period defined by statistical regression rather than the promised restoration. Analysis of sovereign data points paints a picture of a republic that slid backward on almost every measurable metric of development.
The General assumed command in 2015 with a mandate to crush corruption and secure the territory. Eight years later the Federation witnessed an entrenchment of patronage and the democratization of violence. This report dissects the mathematical reality of that era. It ignores sentiment to focus purely on the ledger of the state.
Fiscal discipline collapsed completely under the weight of unorthodox monetary experiments. The Central Bank of Nigeria abandoned traditional orthodoxy. It embraced direct financing of federal expenditures. This violation of the CBN Act resulted in a debt profile that metastasized beyond solvency. Abuja printed money to fund its operations.
This triggered hyperinflation that decimated the purchasing power of the middle class. The Naira did not just depreciate. It lost its function as a store of value. Official exchange rates detached from market reality. Arbitrage flourished. A cabal of forex speculators amassed fortunes while manufacturing output shrank.
The following dataset illustrates the sheer velocity of this economic degradation.

Security metrics reveal a similar trajectory of failure. The administration claimed technical defeat of Boko Haram in the Northeast. Yet violence metastasized into the Northwest and North Central zones. Banditry replaced insurgency as the primary threat vector. Kidnapping evolved from an ideological tactic into a commercial enterprise.
Non-state actors exercised sovereignty over vast swathes of territory in Zamfara and Niger states. Farmers abandoned harvests. Food insecurity surged. The state monopoly on violence evaporated. Citizens turned to self-help groups. Warlords collected taxes where the Federal Inland Revenue Service could not reach.
Infrastructure stands as the sole counter-argument presented by apologists. Steel and concrete investments did materialize. The Second Niger Bridge reached completion. Rail lines connected Lagos to Ibadan. These projects exist physically. Yet the financing model casts a long shadow over their utility.
Abuja borrowed commercially to fund social infrastructure with low immediate returns. Servicing these loans consumes nearly all government revenue. Future generations inherit the rails but also the crushing liabilities attached to them.
Institutional integrity suffered grave erosion. The executive branch repeatedly disobeyed court orders. The Department of State Services operated with impunity. A raid on the homes of Supreme Court justices signaled a subjugation of the judiciary. This weakened the rule of law. Foreign capital fled. Investors seek predictable legal environments.
They found a regime that altered rules by fiat. The closure of land borders in 2019 exemplifies this erratic policymaking. It achieved nothing regarding smuggling but destroyed legitimate regional trade.
Anti-corruption efforts devolved into political weaponry. The Economic and Financial Crimes Commission focused on opposition figures while cabinet members faced credible accusations without consequence. The "accountant general" of the federation allegedly embezzled over 100 billion Naira.
Pardons granted to convicted former governors convicted of theft shattered the moral argument of the presidency. Transparency International consistently ranked the nation lower on corruption indices throughout the tenure.
Oil production collapsed during a global price boom. While other petroleum states built reserves the Nigerian National Petroleum Corporation failed to meet OPEC quotas. Industrial scale theft occurred under the watch of security agencies. Pipelines functioned as open taps for syndicates.
The treasury received zero remittance from crude sales for months at a time. This represents a forensic anomaly of immense proportions. It suggests state complicity in the looting of national resources.
Buhari left a polarized citizenry. Ethnic and religious fault lines widened. The governing style favored nepotism. Appointments skewed heavily toward the president's region. This violated the federal character principle enshrined in the constitution. Trust in the union hit historic lows. The exodus of skilled professionals accelerated.
Doctors and engineers voted with their feet. They chose migration over stagnation. This "Japa" phenomenon represents a brain drain that will cripple the domestic workforce for decades.
