Banking Market Size Structure and Financial Stability: Evidence from Eight Asian Countries

Using commercial bank data from eight major Asian countries, we examine the relationship between the banking market size structure and the stability of financial institutions. We also analyze the effect of bank upsizing on the financial stability. Our results show that a rise in large banks’ market power, accompanying an increase in their market shares, lowers the capital adequacy of small banks. Small banks’ nonperforming loans and the possibility of their bankruptcy also increase as large banks’ market shares rise. We further show that larger banks tend to have lower capital adequacy ratios, liquidity ratios, and distance-to-default ratios. Our study suggests that large banks’ greater market shares are associated with small banks’ financial instability. Overall, these findings are consistent with the notion of the recent banking literature that has important antitrust policy implications.

Market Size Structure and Small Business Lending: Are Crisis Times Different from Normal Times?*

Conventional wisdom holds that small banks have comparative advantages vis-à-vis large banks in serving small firms, while recent literature suggests this may not be the case. Using a panel of recent US start-ups, we investigate how small bank presence affects these firms in normal times (2004–06) and in the recent financial crisis (2007–09). We find that greater small bank presence yields significantly more lending to and slightly lower failure rates of these firms during normal times. However, these benefits disappear during the financial crisis, possibly because small banks are less diversified and benefit less from government guarantees than large banks.

Banking Market Conditions and Deposit Interest Rates

This paper addresses the impact market conditions on bank deposit interest rates. Examining data for 1988-2000, we find that rates are affected by market size structure (defined as the distribution of market shares of banks of different sizes whether or not the market share is achieved entirely in that local market). This is in addition to the effects of market concentration noted in earlier work. We also find large differences between urban and rural markets. In rural areas, changes in market concentration have no effect on deposit rates. These findings have implications for antitrust policy in banking.

Banking market conditions and deposit interest rates

This paper shows that the impact of market structure on bank deposit interest rates is complex. Both market size structure and multimarket bank presence have independent effects on rates. There is evidence that mid-size banks were more aggressive competitors than other banks, but that the effect of market structure on deposit rates has evolved over time, with mega-banks recently becoming more aggressive competitors. This may be related to the growth of mega-banks in many markets. These findings have implications for existing theories of deposit pricing and, by extension, antitrust policy in banking.

Does market size structure affect competition? The case of small business lending

Market size structure refers to the distribution of shares of different size classes of local market participants, where the sizes are inclusive of assets both within and outside the local market. We apply this new measure of market structure in two empirical analyses of the US banking industry to address concerns regarding the effects of the consolidation in banking. Our quantity analysis of the likelihood that small businesses borrow from large versus small banks and our small business loan price analysis that includes market size structure as well as conventional measures yield very different findings from most of the literature on bank size and small business lending. Our results do not suggest a significant net advantage or disadvantage for large banks in small business lending overall, or in lending to informationally opaque small businesses in particular. We argue that the prior research that excluded market size structure may be misleading and offer some likely explanations of why our results differ.

The Effect of Market Size Structure on Competition: The Case of Small Business Lending

Banking industry consolidation has raised concern about the supply of small business credit since large banks generally invest lower proportions of their assets in small business loans. However, we find that the likelihood that a small business borrows from a bank of a given size is roughly proportional to the local market presence of banks of that size, although there are exceptions. Moreover, small business loan interest rates depend more on the size structure of the market than on the size of the bank providing the credit, with markets dominated by large banks generally charging lower prices.
