Monetary policies in advanced economies and emerging markets face quite different challenges at the current juncture. In the advanced countries, current dilemmas derive from the normalisation of unconventional monetary policies. The short-term dilemma is to determine when to start exiting extraordinary policies and selecting appropriate tools, as conventional tools may not be very relevant during this phase. The medium- to long-term challenges relate to the sequencing, pace and mechanics of normalisation. Monetary policy in emerging markets needs to cope with the familiar dilemmas of fiscal dominance, the growth-inflation trade-off and the "impossible trinity." With fiscal parameters in control, and food and commodity prices subdued, the chief dilemma currently confronting emerging markets involves a trade-off between targeting divergent domestic and external cycles. Although they are now better placed to absorb a sudden stop, the impact is likely to be differential, with those with weaker macroeconomic parameters suffering greater pain.
