A Theory of Precautionary Regulatory Capital in Banking*
Phong T. H. Ngo(School of Finance and Applies Statistics, College of Business and Economics, Australian National University, ACT, Australia)

The orthodox assumption in the banking literature is that capital requirements are a binding constraint on banking behavior. This is in conflict with the empirical observation that banks hold a buffer of capital well in excess of the minimum requirements. This paper develops a model where capital is endogenously determined within a profit-maximizing equilibrium. Optimality involves balancing the reduction in expected costs associated with regulatory breach with the excess cost of financing from increasing capital. We demonstrate that when the equilibrium probability of regulatory breach is less than one-half, banks are expected to hold precautionary capital.

We investigate the gains and losses from equity trades of individual investors, various institutional investors, and foreign investors in the Tokyo Stock Exchange. We develop a trade-weighted performance measure and examine the impact of trading intervals, price spreads, and market timing on performance. We find that different investor types gain or lose from different sources. For example, we discover that individual investors have poor market timing ability but potentially gain during short-run trading intervals as their average sell price is consistently higher than the average purchase price. In contrast, we find that foreign investors consistently generate gains from trade due to good market timing, although their average sell price is lower than the average purchase price. Also, we find that foreign investors extract significant portion of their gains by trading against Japanese institutional investors when Japanese investors trade before their fiscal-year end.

US banks making prime rate revisions are known to suffer stock price declines, which is consistent with the Stiglitz–Weiss adverse selection theory, given the relative stickiness of interest rates. If banks suffer price declines, then why are some banks consistent leaders when revising prime rates? This research question is the focus of our paper and is examined in the relatively concentrated banking system of Singapore. Lead banks in Singapore initiating a large number of rate increases earned an average abnormal return of 5.2%, while non-lead banks also experienced positive abnormal returns of 3.9%, a result not in agreement with US-specific evidence. We argue that the rate increases (decreases) resulting in a significant stock price increase (decrease) for lead banks are consistent with a valuation effect in a concentrated banking system. Our results could be explained as a valuation effect from anticipated higher profits or as reward for being first. The first mover advantage may thus also have signaling value on quality.
