Thus, central banks in many advanced and emerging economies are facing a nightmare scenario, in which they simultaneously must tighten monetary policy (to fight inflation) and ease it (to reduce the downside risks to growth). As inflation and growth risks combine in varied and complex ways in different economies, it will be very difficult for central bankers to juggle these contradictory imperatives.
因此，许多发达经济体和新兴市场经济体的中央银行都面对着恶梦般的情形，它们必须同时既紧缩货币政策（以遏制通货膨胀）又放松货币政策（以减小经济下行的风险）。因为在不同的经济体中通货膨胀和增长风险以各种复杂的方式结合在一起，中央银行要同时处理这些对立的紧急任务将会变得十分困难。
