Does the rescue of a troubled lender halt regional bank share declines?
Core argument: A KBW index of regional bank stocks fell more than 5 percent in morning dealings as investors digested JPMorgan's takeover of First Republic alongside gloomy economic data.
The rescue of First Republic this week has failed to arrest a sell-off in regional bank shares, which plunged on Tuesday morning as investors digested JPMorgan’s takeover of the troubled Californian lender along with gloomy economic data. A KBW index of regional bank stocks slid more than 5 percent in morning dealings. Investors have been heavily betting on further share declines in some of the mid-sized banks, with short interest in California-based PacWest particularly high. However, the level of shorting activity is little changed over the past month, according to Markit data.
