We examine whether and how banks’ diversification strategy responds to expected investment opportunities. We find evidence consistent with the view that whether banks diversify to develop internal funding capability in response to good prospects, or to search for new growth opportunities in response to poor prospects in the current activity, depends on external capital constraints. The results further suggest that banks find it optimal to have immediate control over the internal fund allocation rather than relying on the allocation managed by their group parent. We also find evidence suggesting that although international diversification can facilitate activity diversification, the former is unlikely to substitute for the latter. In addition, there is no evidence that activity diversification by banks reflects inefficient diversification.
