Ivorian tycoon Jean Kacou Diagou's NSIA Banque lifts profit 7% as balance sheet tops $5 billion

NSIA Banque Côte d'Ivoire pushed its balance sheet past 3 trillion CFA francs for the first time last year, a milestone for the lender at the centre of Jean Kacou Diagou's bancassurance group.

The Abidjan-based bank reported net profit of $70.76 million (40.7 billion CFA francs) for 2025, up 7%, as loan growth and a surge in deposits offset heavier provisioning. Total assets rose 22% to $5.34 billion (3,073 billion CFA francs).

Lending drove the expansion. Outstanding loans climbed 18% to $3.16 billion (1,819 billion CFA francs), with credit to businesses rising 26%. Customer deposits grew faster still, up 32% to $3.90 billion (2,242 billion CFA francs), helped by a 47% jump in demand deposits.

That deposit mix matters more than the headline. Demand deposits are the cheapest funding a bank can raise, and a sharp rise in them gives NSIA room to lend without squeezing margins, a useful cushion as competition intensifies across Côte d'Ivoire's banking market.

Income tracked the growth. Net banking income rose 15% to $196.29 million (112.9 billion CFA francs), with stronger interest income covering a decline in fees. Operating costs rose just 7%, lifting gross operating income almost 30% to $89.19 million (51.3 billion CFA francs) and pulling the cost-to-income ratio down to 54.6%.

Profit grew more slowly than the operating line because management chose to set money aside. The bank raised provisions under what it describes as a more cautious risk policy, capping earnings growth rather than letting it run. Non-performing loans stood at about 7% of the book, against a West African Economic and Monetary Union average closer to 10%.

Capital held up. The solvency ratio reached 13.15%, comfortably above the 11.5% regulatory floor. Shareholders will vote on a dividend of $33.03 million (19 billion CFA francs), a payout ratio of about 47%.

The bank also completed an $86.93 million (50 billion CFA franc) receivables securitisation, the first multicurrency deal of its kind in the regional bloc, structured in both CFA francs and euros. It continued lending into housing, small business, agriculture and energy.

The start to this year has been stronger than the year just reported. First-quarter net banking income rose 28% and net profit jumped 53%.

Diagou built the group behind these numbers from a standing start. He trained at the École nationale d'assurances in Paris in 1972, climbed through the African subsidiaries of French insurer UAP, and helped draft the CIMA code that governs insurance markets across 14 francophone African countries. In January 1995, at a moment when local investors doubted an Ivorian firm could take on entrenched European insurers, he founded Nouvelle Société Interafricaine d'Assurance with $521,600 (300 million CFA francs) in capital.

The break came within a year. Assurances Générales de France pulled out of Côte d'Ivoire in 1996, and NSIA bought its life and non-life units, transforming a startup into a serious player overnight. Expansion followed into Benin, Gabon, Senegal, Congo and Togo.

Banking came in 2006, when NSIA acquired BIAO Côte d'Ivoire, then one of the country's largest banks, and became the first Ivorian group to pair banking with insurance under one roof. The purchase was structured under a new parent, NSIA Participations. BIAO was later rebranded as NSIA Banque Côte d'Ivoire and listed on the BRVM, the regional exchange in Abidjan.

The group now spans 12 countries in West and Central Africa across roughly 31 companies, employing more than 2,800 people. Its banking arm has subsidiaries in Côte d'Ivoire, Benin and Guinea, branches in Senegal and Togo, and ambitions in Cameroon. It bought the francophone arm of Nigeria's Diamond Bank for 61 million euros in 2017 and took a 25% stake in Orange Bank Africa, the region's first fully digital bank.

Diagou has spent the past year tightening his grip. His family's investment vehicle, Manzima Holding, bought out the National Bank of Canada's 22.6% stake in NSIA Participations in April 2025, lifting the family holding to 68.73% and ending a decade-long partnership. Swiss Re, which invested $112 million in 2017, remains a shareholder. Diagou's daughter, Janine Bénédicte Kacou Diagou, runs the banking division.

The consolidation was framed around a single objective: building one strong financial holding company. The 2025 results are the first full-year test of what the family now controls outright.

Whether the provisioning proves prudent or merely conservative will be settled in the loan book over the next two years.
