The “Gatekeeper” Era (2015–2020)
Kyari redefined the office of the Chief of Staff, moving it from a purely administrative role to the nerve center of the Nigerian government.
-
The Mandatory Channel: After Buhari’s 2019 re-election, the President famously ordered his cabinet ministers to channel all requests and memos through Kyari’s office. This consolidated immense power in his hands, making him the ultimate arbiter of who and what reached the President’s desk.
-
Economic Nationalist: Influenced by developmental economists like Amartya Sen, Kyari championed “inward-looking” policies. He was a chief architect of the Siemens Power Deal, traveling to Germany personally to negotiate a blueprint for fixing Nigeria’s electricity grid.

The P&ID Savior: Historical accounts in 2025 highlight that it was Kyari who took the lead in 2019 to challenge the fraudulent $11 billion P&ID award against Nigeria. While others pushed for a settlement, Kyari insisted on a legal fight in London, a strategy that eventually saved Nigeria from fiscal catastrophe years after his death.
Passing and 2026 Historical Status
As of January 9, 2026, Mallam Abba Kyari’s influence is viewed through a lens of institutional discipline and the “Buhari Shadow.”
-
The COVID-19 Martyr: Kyari was the first high-profile Nigerian official to die from COVID-19 complications. He contracted the virus while on an official mission to Germany to finalize the Siemens power agreement, leading many supporters to describe him as a “martyr who died in active service.”
-
Legacy of Discipline: In recent 2025 memorial essays, former colleagues have contrasted Kyari’s “spartan and exacting” administrative style with the more decentralized approach of subsequent administrations. He is remembered for wearing a signature white baban riga and red Kanuri cap, living a life of personal simplicity despite his proximity to power.
-
Posthumous Honors: In late 2022, he was posthumously conferred with the Commander of the Order of the Federal Republic (CFR), Nigeria’s third-highest national honor, in recognition of his service.
Professional Profile
-
The Intellectual Powerhouse: With degrees from Warwick and Cambridge and a career spanning the top echelons of United Bank for Africa (UBA) and Unilever, Kyari was often considered the “intellectual engine” of the Buhari presidency.
-
The Controversies: His tenure was not without friction. He had high-profile public disagreements with the former Head of Service (Winifred Oyo-Ita) and the National Security Adviser (Babagana Monguno), instances often cited by critics as proof of “presidential overreach.”
