Tidjane Thiam

Tidjane Thiam (born July 29, 1962, Abidjan, Côte d’Ivoire) is an Ivoirian-born international businessman and politician who has headed prominent global financial institutions as well as worked in the Ivoirian government. He has served as president of the Democratic Party of Côte d’Ivoire–African Democratic Rally (Parti Démocratique de Côte d’Ivoire–Rassemblement Démocratique Africain; PDCI-RDA) political party since 2024. Thiam attempted to stand in Côte d’Ivoire’s 2025 presidential election, but his candidacy was disqualified over the dual French-Ivoirian citizenship he had held for many years.

Early life and family

Thiam was born in Côte d’Ivoire, the youngest of seven children in a family with a political pedigree. His mother, Mariétou, was the niece of Félix Houphouët-Boigny, Côte d’Ivoire’s first president, who ruled the country for more than three decades. His father’s side also had political prominence: Thiam’s father, Amadou, was originally from Senegal, and Amadou’s brother, Habib Thiam, held various positions in the Senegalese government from the 1960s to the ’90s, including prime minister. Amadou was a journalist who, in 1963, was the Ivoirian minister of information. He was jailed for two years early in Tidjane Thiam’s life on charges of trying to overthrow the Ivoirian government, but was acquitted. Thiam later spent part of his childhood in Morocco, where his father served as ambassador (1966–78).

Education and early business career

An excellent student, Thiam became the first Ivoirian to pass the entrance exam for École Polytechnique (French: “Polytechnic School”), an elite university in Paris, from which he graduated in 1984 with a degree in engineering. He then attended École Nationale Supérieure des Mines de Paris (French: “National School of Mines of Paris”; now Mines Paris–PSL) and graduated with a degree in civil engineering in 1986. That year, Thiam took a job at the consulting firm McKinsey & Company in France and, over the course of his career there, would work in Paris, London, and New York. While at McKinsey, he earned an MBA from the European Institute of Business Administration (INSEAD) at Fontainebleau, near Paris, in 1988. The next year, Thiam moved to the World Bank before returning to McKinsey in 1990.

Public sector work and cabinet minister

In 1994 Thiam came back to Côte d’Ivoire to work in the public sector, overseeing the National Bureau for Technical Studies and Development, an agency in charge of infrastructure projects. In 1998 he was named the minister of planning and development, but his time in that position was cut short when the country was rocked in late 1999 by a military coup. At first, the military junta put Thiam under house arrest, but later offered him a job in the new government. He declined the post, ending that chapter of his government experience, and came back to Europe to focus on his business career.

Successful return to the private sector

Thiam returned to work at McKinsey in 2000 before moving to Aviva, a British insurance company, in 2002, where he later became CEO of the company’s European division. In 2008 he moved again to become the CFO of London-based Prudential, a financial services and insurance company. The next year, he was made CEO, and the company’s stock price tripled and its profits doubled while he was chief executive.

Those impressive accomplishments led the chairman of Zurich-based Credit Suisse, Urs Rohner, to attempt to recruit Thiam as the company’s chief executive. Thiam was initially cautious about making the jump: He told Euromoney magazine in 2018, “I actually said no twice.” He eventually took the job and helped turn around a company that was “in a deep funk,” as The New York Times described it in 2020. Thiam’s impact was immediate. The very day in 2015 that the company announced his hiring, its shares jumped 7 percent. The bank returned to profitability under his tenure.

But in some ways, his time at Credit Suisse was personally difficult. The Times reported that Thiam, the only Black chief executive at banking’s highest echelons, endured a “series of painful incidents…some moments were shocking, others disturbing; most had to do with tensions around being Black in a predominantly white industry and an overwhelmingly white city.” A scandal that the Swiss media dubbed “spygate” forced Thiam to resign in February 2020 after revelations that the company’s chief operating officer had ordered surveillance of some former employees. Even though Thiam denied knowledge of it and was cleared of involvement, the taint of the scandal led to his ouster.

Political career

In late 2023 Thiam was elected leader of the PDCI-RDA, a prominent political party in Côte d’Ivoire, and officially stepped into his new role in early 2024. In April 2025 the PDCI-RDA named him as the party’s candidate for the country’s presidential election scheduled for later that year.

Under Côte d’Ivoire’s constitution, presidential candidates must be exclusively Ivoirian citizens. In addition to having been born an Ivoirian citizen, Thiam had held French citizenship since 1987. In anticipation of getting his party’s nomination for the role, he had renounced his French citizenship in February 2025 so he would be eligible to run; this was officially recognized by France in March. However, just days after being announced as the PDCI-RDA candidate, he was struck from the voter roll because he held French citizenship at the time of his registration, and in September he was one of several candidates declared ineligible to stand in the presidential election by the Constitutional Council. Many analysts thought Thiam would have been the strongest challenger to the incumbent president, Alassane Ouattara, in the October 2025 election.
