US regulators are coming under increasing pressure to restore confidence in regional banks, following a turbulent week for share prices. JP Morgan analysts predicted that the government may need to take emergency steps such as halting short-selling of bank stocks to prevent further damage. They also suggested measures such as expanding deposit insurance or limiting information being spread on social media. The calls came after a tumultuous week for US banks, which saw First Republic Bank bought out of government receivership by JP Morgan and several other banks suffer sharp falls in their share prices.
