Bank capital is a principal aspect of regulation and will determine how long a bank remains in business from a regulatory point of view. Prior research on the relationship between capital and profitability has largely focused on developed economies, especially the USA, and Europe and the results have been inconclusive. There is no evidence of such research done to date that focuses on an emerging economy such as South Africa. Using South Africa as a unit of analysis and using the Generalised Methods of Moments (GMM), and Panel Two Stage Least Squares (2SLS) or Pooled IV method as the estimation techniques, this study tested the hypothesis that there is a positive and statistically significant relationship between bank capital and profitability. The results provided evidence of a positive relationship between capital ratio (CAR), return on equity (ROE) and return on assets (ROA). From a bank specific strategic decision-making perspective, this would assist financial institutions and investors in tailoring investment decisions in response to policy decisions that relate to bank capital. From the public policy perspective, this would assist both governments and regulators in formulating better- informed policy decisions regarding the importance of bank capital. (original abstract)

Kapitał bankowy jest zasadniczym aspektem regulacji i określa, jak długo bank utrzyma się na rynku z regulacyjnego punktu widzenia. Wcześniejsze badania dotyczące związku między kapitałem a rentownością w dużej mierze koncentrowały się na gospodarkach rozwiniętych, w szczególności USA i Europie, a ich wyniki były niejednoznaczne. Natomiast jak dotąd brak jest wyników badań dotyczących gospodarek wschodzących, takich jak RPA. Wykorzystując Republikę Południowej Afryki jako przedmiot analizy i stosując Uogólnioną Metodę Momentów (GMM), Podwójną Metodę Najmniejszych Kwadratów (2SLS) lub metodę zmiennych instrumentalnych (Pooled IV method) jako techniki szacowania, w badaniu zweryfikowano hipotezę zakładającą, że istnieje dodatni i statystycznie istotny związek między kapitałem banku a zyskiem. Wyniki analizy dostarczyły dowodów na pozytywny związek między współczynnikiem adekwatności kapitałowej (CAR), rentownością kapitału własnego (ROE) i rentownością aktywów (ROA). Z punktu widzenia podejmowania decyzji strategicznych przez bank wyniki niniejszych badań mogą pomóc instytucjom finansowym i inwestorom w dopasowaniu decyzji inwestycyjnych do polityki państwa dotyczącej kapitału bankowego. Natomiast z punktu widzenia polityki państwa, może pomóc to zarówno rządom, jak i organom regulacyjnym, w formułowaniu bardziej świadomych decyzji dotyczących znaczenia kapitału bankowego.
