The document discusses emergency policy measures taken by governments during the 2008 financial crisis to address bank failures and restore confidence in the financial system. These measures included expanding retail deposit insurance, guaranteeing wholesale bank liabilities, injecting capital into banks, and purchasing troubled assets. The policies aimed to address issues like lack of confidence, uncertainty, frozen credit markets, and bank undercapitalization. However, the broad guarantees introduced moral hazard and funding issues. They also complicated existing deposit insurance systems. Governments must address the root causes of confidence problems to prevent future crises.
