Abstract

No final de 2025, segundo dados oficiais do BNA, o sistema bancário angolano detinha cerca de 9,3 biliões de kwanzas em títulos e valores mobiliários, e tinha concedido 8,98 biliões em crédito à economia, num activo total de 26,59 biliões. A foto fixa diz pouco. Diz muito a trajectória dos últimos cinco anos: a carteira de títulos cresceu sistematicamente acima do crédito à economia, e foi essa divergência continuada, mais do que qualquer decisão dramática num ano específico, que produziu uma exposição soberana próxima dos 35 por cento dos activos do sector. Argumento neste artigo que o fenómeno é estrutural e corresponde ao que a literatura chama nexo soberano-bancário, operando em Angola através de quatro canais: balanço (risco latente), crowding out (custo activo e quotidiano para a diversificação económica), pró-cíclico (amplificador dos choques petrolíferos) e repressão financeira (com indícios documentados, ainda que sem consagração normativa). A interacção destes canais com o original sin cambial, numa economia em que 79 a 83 por cento da dívida pública está denominada em moeda estrangeira, gera vulnerabilidades que a literatura convencional, desenvolvida sobretudo para a zona euro, não capta adequadamente. Proponho quatro eixos de política: alargamento da base de investidores em dívida pública, reforma dos incentivos regulatórios de Basileia III, desenvolvimento do mercado de capitais, e reforço da supervisão macroprudencial pelo BNA. As experiências comparadas do Ghana, da África do Sul e de Portugal informam estas propostas, sem nunca as determinar. Concluo que o nexo angolano configura um desvio estrutural da função de intermediação financeira, e que a distância entre a situação actual e uma crise de estabilidade financeira pode ser mais curta do que os indicadores agregados sugerem.As of 31 December 2025, according to official BNA data, Angola's banking system held approximately 9.3 trillion kwanzas in securities and 8.98 trillion in credit to the economy, against total assets of 26.59 trillion. The static snapshot says little. What says a great deal is the trajectory: over the past five years, the securities portfolio has grown systematically faster than credit to the economy, and it is this divergence that has produced, quietly, a sovereign exposure close to 35 percent of sector assets. I argue in this paper that the phenomenon is structural and corresponds to what the literature calls the sovereign-bank nexus, operating in Angola through four channels: balance sheet (latent risk), crowding out (active daily cost to economic diversification), pro-cyclical (amplifier of oil shocks) andfinancial repression (documented indications, albeit without normative expression). The interaction of these channels with currency original sin, in an economy where 79 to 83 percent of public debt is denominated in foreign currency, creates vulnerabilities that the conventional literature, developed for the eurozone, does not adequately capture. I propose four policy axes: broadening the investor base for public debt, reforming the regulatory incentives of Basel III, developing capital markets and strengthening macroprudential supervision by the BNA. The comparative experiences of Ghana, South Africa and Portugal inform these proposals without ever determining them. I conclude that the Angolan nexus constitutes a structural deviation of the financial intermediation function, and that the distance between the current situation and a financial stability crisis may be shorter than aggregate indicators suggest.
