Nine Ghanaian private banks collapsed during the country’s 2017–19 financial crisis. Apart from public audits that revealed liquidity problems and large portfolios of non-performing loans, the crisis generated vibrant debate on ‘indigenous banks’ as integral to national economic sovereignty. At the centre of these debates was a contested central bank-led project to inject equity in five struggling Ghanaian banks through a special purpose vehicle (SPV), Ghana Amalgamated Trust (GAT). Set against the historical dominance of foreign banks in West Africa and Ghana’s recent history of political fault lines, this article explores the moral discourses and popular discontents of harnessing an SPV – a device typically used to isolate financial risk – for a desire for African economic sovereignty. Drawing on banking archives, public debates and fieldwork in a private bank selected as a benefactor of the SPV, I focus on the contests of value that emerge when costly banking sector reforms meet a critical public that doubts the sincerity of politicians and bankers as economic ‘reformers’. Arguing that ‘indigenous banks’ became a moral category that embedded abstractions of finance in a nationalist discourse of affect and sentiment, this article illuminates the long history of centring domestic ownership of financial infrastructures in postcolonial African economic policymaking.
