Senegal’s president Bassirou Diomaye Faye on Monday installed a seasoned economist with long experience at the regional central bank as prime minister, three days after the abrupt dismissal of his firebrand predecessor Ousmane Sonko. Ahmadou Al Aminou Lo, who previously headed the Senegalese branch of the Central Bank of West African States, appeared on state television to pledge that the country remained “a safe and reliable” destination for private capital, but acknowledged the “state of emergency” facing public finances. The appointment, viewed from Dakar, represents a decisive pivot from the populist rhetoric of Sonko, who had championed a sovereign approach to the country’s massive debt pile, to a figure described as knowing “the inner workings of the economy and finance”.

The rupture between the former allies, who swept to power in 2024, built for months against a backdrop of a financial crisis that saw Faye accuse the previous administration of concealing billions in debt. The discovery of hidden obligations equivalent to around €7 billion—132 percent of GDP—led to the suspension of a $1.8 billion IMF programme agreed in 2023. Sonko, barred from the presidential race and having thrown his weight behind Faye, was dismissed by decree on Friday along with the entire government. In a cryptic social media post that evening, Sonko wrote simply: “Tonight I will…” – a message that left his large youth following speculating about his next move. The turmoil deepened on Sunday with the resignation of parliament speaker El Malick Ndiaye, a senior PASTEF figure, who cited the “higher interest of the nation”.

Viewed from Johannesburg, investors and analysts see the sacking as both an opportunity and a risk for the stalled negotiations with the International Monetary Fund. While Sonko’s strident criticism of debt restructuring had been a key obstacle, his removal creates fresh political uncertainty, according to Thalia Petousis, portfolio manager at Allan Gray. She warned that a newly appointed prime minister might still favour a deep debt restructuring that could hurt bondholders. From London, analysts note that Lo’s technocratic profile could facilitate a return to the negotiating table, but factional fallout within PASTEF and unclear allegiances in parliament raise the spectre of legislative paralysis. Parliament was set to convene on Tuesday to vote on reinstating legislative business, a process now clouded by the leadership vacuum.

The next weeks will test whether Faye can convert the appointment of a trusted central banker into a workable governing coalition and, crucially, an IMF board-level agreement. Viewed from Washington, the Fund is likely to welcome a more orthodox interlocutor, but it will be wary of contingent liabilities and the political capacity to deliver on fiscal consolidation. In Dakar, the immediate priority is reassuring a jittery private sector and foreign investors who had grown accustomed to Sonko’s combative style. The Senegalese crisis, playing out against a backdrop of regional security concerns and global economic headwinds—including the domestic fallout from the Iran war cited by some officials—remains both a litmus test for the new administration’s credibility and a bellwether for sovereign risk in West Africa.
