Mauritania’s Sidi Ould Tah Takes Over as African Development Bank Chief

Mauritania’s former economy minister, Sidi Ould Tah, has assumed office as head of the African Development Bank, pledging to build a “robust and prosperous” Africa. He takes over at a difficult time, with U.S. plans to cut $500 million in funding, declining foreign aid, rising debt, and climate challenges. Tah urged action, stressed peace as key to development, and proposed seeking new funding sources, particularly from Gulf countries.

Mauritania’s former Minister of Economy, Sidi Ould Tah, on Monday officially took office as the new head of the African Development Bank, where he pledged to dedicate his leadership to building a “robust and prosperous” Africa. His inauguration marks the beginning of a significant new chapter for the bank, which plays a vital role in financing and supporting development across the continent.

The African Development Bank is widely recognized as one of the world’s largest multilateral development institutions. It functions by drawing on several sources of funding, including subscriptions from member states, loans raised on international markets, repayments from previous projects, and income generated from its own loan portfolio. Over the decades, the bank has become a cornerstone for African countries seeking funding for infrastructure, education, healthcare, and climate resilience projects. Yet, despite its strong foundation and influence, the institution is entering a challenging phase. The administration of U.S. President Donald Trump has announced plans to withdraw $500 million in funding previously allocated to AfDB programs designed to assist low-income countries. This potential cut presents a critical hurdle that Tah and his team will have to navigate as they chart the future direction of the bank.

In his remarks delivered after being sworn in at the AfDB’s headquarters in Abidjan, Côte d’Ivoire, Tah expressed both optimism and determination. He reiterated his belief in the bank’s mission, declaring, “We are united by a shared responsibility: building a robust and prosperous Africa.” His statement was not only a reaffirmation of the bank’s guiding principles but also a call for renewed commitment from all stakeholders at a time when Africa faces mounting difficulties.

Tah identified several key challenges that the continent must urgently address. Among these are the decline in foreign development aid, which has historically supported many African governments in financing basic services; the growing weight of external debt, which threatens economic stability in multiple countries; and the intensifying impact of climate change, which disproportionately affects African nations despite their relatively small contribution to global emissions. He stressed that overcoming these hurdles would require innovative approaches and strong collaboration between governments, financial institutions, and international partners. “The eyes of Africa are on us, the youth is waiting, the time is for action,” Tah declared passionately, underscoring that sustainable peace and stability are indispensable foundations for achieving the continent’s broader development objectives.

During his campaign for the AfDB presidency, Tah outlined a vision that included expanding the bank’s resource base beyond traditional donors. With Western countries signaling a reduction in foreign aid, he argued that Africa must look toward alternative partnerships, particularly with Gulf nations, which he identified as potential new contributors to the continent’s development agenda. This approach reflects a strategic shift that could help cushion the impact of funding shortfalls while creating opportunities for fresh investment and collaboration.

At the age of 60, Sidi Ould Tah brings considerable experience and knowledge to his new role. He served as Mauritania’s Minister of Economy from 2008 to 2015, a period during which he played a central role in shaping his country’s economic policies and managing key development programs. His election in May to lead the AfDB made him the successor to Nigeria’s Akinwumi Adesina, who had served as the bank’s president since 2015. Tah’s appointment is seen by many observers as both a continuation of the AfDB’s longstanding mission and a chance to infuse the institution with renewed direction at a time of uncertainty.

By stepping into this role, Tah assumes responsibility for guiding an institution that not only finances projects but also symbolizes Africa’s collective aspirations for self-reliance, resilience, and inclusive growth. The coming years will test his ability to balance financial realities with the high expectations of a continent eager for progress.
