The IMF’s projection is just over four percent for real global GDP growth. The consensus of private forecasters sees growth in Europe and Japan close to estimates of potential, or in the neighborhood of two percent. Growth in the major emerging markets looks impressive, reflecting not only the benefits of a positive external environment, but also the impact of better economic leadership and policies more supportive of macroeconomic stability and reduced external vulnerability. In China, officials now seem more confident that they have induced the desired moderation in growth to a more sustainable, but still high pace of growth. The global economy has weathered the oil price shock quite well. If the long term futures prices are right, we need to be prepared to live with the possibility of a sustained period of higher oil prices, and perhaps more volatility in oil prices, and the world seems to be getting itself more prepared for that prospect. In the financial markets, this broadly positive outlook has been accompanied by a dramatic reduction in risk premia, leaving the price of insurance unusually low against a less favorable or more volatile environment. These developments imply a view among market participants that future macroeconomic shocks will be more moderate than in the past and more likely to be absorbed without broader damage to economic performance or the financial system. They reflect a general increase in confidence that monetary authorities here and in other countries can keep inflation stable at appropriately moderate levels.
They reflect diminished uncertainty about the expected path of monetary policy in the United States. And they imply that the imbalances in the global economy will be diffused smoothly. Of course, not much is certain in economics and finance. One cannot know with confidence whether future economic policies and outcomes will justify the confidence in the benign outlook now reflected in risk premia. What are the broader challenges and forces that will dominate the policy agenda and affect economic outcomes? I want to touch on four, though this is a selective list. First, all of the major economies face difficult fiscal sustainability issues, and these will be exacerbated by the approaching demographic cliff. Fiscal policy in most of the major economies is on a path that will lead to increasing, rather than stable or falling debt-to-GDP ratios. In virtually all the major economies, the cost of committed benefits substantially exceeds the stream of tax resources available under current policies. If one were to produce a ten year forecast of the U.S. fiscal position using the  fan charts to illustrate uncertainty that are a feature of the inflation reports of many central banks, the size of the fan would be very wide, indicating a substantial probability of deficits significantly worse than the already troubling central path for the deficit predicted given current policies.
