The European Central Bank’s announcement of its “outright market transactions” program has reduced the risk of a sovereign-debt crisis in the eurozone periphery and a breakup of the monetary union. The Bank of England has moved from QE to CE (credit easing), and the Bank of Japan has repeatedly increased the size of its QE operations.
答案很简单：中央银行再一次祭出了流动性大杀器，这给了风险资产一剂强心剂。美联储采取了激进的无期限量化宽松（QE）。欧洲央行所宣布的“直接货币交易”计划降低了欧元区外围国主权债务危机和货币联盟崩溃的风险。英格兰银行从QE转向了CE（信用宽松），日本银行则再度增加了QE操作规模。
