Abstract Monetary authorities around the world are implementing enhanced banking capital adequacy requirements under Basel III meant to improve financial stability. Critics however argue that increased capital requirements concentrate the banking industry reducing competition while not guaranteeing financial sector stability. Using data from 167 banks in 37 African countries, we find that increased capital beef-up significantly increases financial instability in Africa (except in big banks) implying that higher capital requirements did not make African banks safer. We also find that increased regulatory capital improves competitive pricing for foreign banks while it makes domestic banks less competitive mainly attributed to the high cost of sourcing and holding extra capital for domestic banks compared to foreign banks who can source cheaper capital from parent companies. The results put to question the effectiveness of enhanced regulatory capital on stability and competitiveness of the African financial system.

非洲的资本需求,银行竞争与稳定

摘要世界各地的金融管理部门正在实施《巴塞尔协议三》下提高的银行资本充足率要求,以提高金融稳定性。然而,批评人士认为,增加的资本要求使银行业集中于减少竞争,同时又不能保证金融部门的稳定。使用来自37个非洲国家/地区的167家银行的数据,我们发现,资本增加的幅度显着增加了非洲的金融不稳定(大银行除外),这意味着更高的资本要求并不能使非洲银行变得更安全。我们还发现,增加监管资本可以改善外资银行的竞争定价,同时也可以降低国内银行的竞争力,这主要是由于与可以从母公司那里获得较便宜资本的外资银行相比,国内银行的采购成本高和持有额外资本。结果使人们质疑增强监管资本对非洲金融体系的稳定性和竞争力的有效性。
