As the year 2018 begins, the world economy is gathering speed. The new
World Economic Outlook Update revises our forecast for the world economy’s growth in both 2018 and 2019 to 3.9 percent. For both years, that is 0.2 percentage points higher than last October’s forecast, and 0.2 percentage points higher than our current estimate of last year’s global growth.
This is good news. But political leaders and policymakers must stay mindful that the present economic momentum reflects a confluence of factors that is unlikely to last for long. The global financial crisis may seem firmly behind us, but without prompt action to address structural growth impediments, enhance the inclusiveness of growth, and build policy buffers and resilience, the next downturn will come sooner and be harder to fight.
Every government should be asking itself three questions today. First, how can we raise economic efficiency and output levels over the longer term? Second, how can we support resilience and inclusiveness while reducing the likelihood that the current upswing ends in an abrupt slowdown or even a new crisis? Third, how can we be sure to have the policy tools we will need to counter the next downturn?
Near-term prospects
Looking first at where we are now, how do we see the world economy in the near term?
The primary sources of GDP acceleration so far have been in Europe and Asia, with improved performance also in the United States, Canada, and some large emerging markets, notably Brazil and Russia, both of which shrank in 2016, and Turkey. Much of this momentum will carry through into the near term. The recent U.S. tax legislation will contribute noticeably to U.S. growth over the next few years, largely because of the temporary exceptional investment incentives that it offers. This short-term growth boost will have positive, albeit short-lived, output spillovers for U.S. trade partners, but will also likely widen the U.S. current account deficit, strengthen the dollar, and affect international investment flows.
