As Russia begins hosting the G20, I thought readers might be interested in my Reuters interview earlier this week making the case for proactive monetary and fiscal policy coordination. There has been a lot of talk of currency wars. I believe that what we are witnessing now are best described as currency skirmishes. The trouble is that a skirmish can easily segue into a war. That is what makes it imperative for nations to have conversations and coordination on monetary and fiscal policies. Skilled interventions are needed on multiple fronts, from managing government debt levels to financing long-term investment in developing countries. My hope is that leaders in Moscow will be attentive to these and might also turn their minds to interventions for the poor, whether they live in far corners of Russia’s great expanse, the townships of South Africa, the favelas of Brazil or the rural hinterlands of China and India.
