Abstract

Japanese regional banks are now facing an existential crisis. Their traditional business model has been devastated by the hollowing out of regional economies, technological change, declining populations and the rapid aging of Japan's non-urban areas. These banks must either go out of business or make significant changes. Reorganizations are a potential change that might solve the problem. Reorganizations include mergers and forming bank holding companies. This research examines regional bank reorganizations over the period from 2008 to 2019. It analyzes the stock market's response to announcements of bank reorganizations. A positive response is defined as stock price appreciation. It is a measure of the value that an efficient financial market attributes to the reorganization. This research finds that some kinds of reorganizations create more value than others. Specifically, mergers between banks within prefectures create more value. Yet, within prefecture mergers have the disadvantage that they might concentrate the provision of banking services in the hands of a few providers, leading to poorer services and higher fees. These reorganizations may violate competition law. Nevertheless, within-prefecture mergers may be a better overall solution to the regional bank crisis.

日本地方银行并购的教训:股市是怎么想的?
日本地区银行目前正面临一场生存危机。地区经济的空心化、技术变革、人口减少以及日本非城市地区的迅速老龄化,摧毁了它们的传统商业模式。这些银行要么倒闭,要么进行重大改革。重组是一个可能解决问题的潜在变化。重组包括合并和组建银行控股公司。本研究考察了2008年至2019年期间的地区银行重组情况。它分析了股市对银行重组公告的反应。积极的反应被定义为股票价格上涨。它是衡量有效的金融市场赋予重组的价值。本研究发现,某些类型的重组比其他类型的重组创造更多的价值。具体来说,县内银行之间的合并创造了更多的价值。然而,在县内合并的缺点是,它们可能会将银行服务的提供集中在少数供应商手中,导致服务质量下降和费用增加。这些重组可能违反竞争法。然而,地区内合并可能是解决地区银行危机的更好的整体解决方案。
