For the first time in a decade, the world’s major economies are growing in sync, a result of lingering low-interest-rate stimulus from central banks and the gradual fading of crises that over years ricocheted from the U.S. to Greece, Brazil and beyond.

All 45 countries tracked by the Organization for Economic Cooperation and Development are on track to grow this year, and 33 of them are poised to accelerate from a year ago, according to the OECD. It is the first time since 2007 that all are growing and the most countries in acceleration since 2010, when many nations enjoyed a fleeting snapback from the global financial crisis.

The International Monetary Fund in July projected global economic output would grow 3.5% this year and 3.6% in 2018, up from 3.2% growth in 2016.

In the past 50 years, simultaneous growth among all the OECD-tracked countries has been rare. In addition to happening last decade, it has only happened in the late 1980s, and for a few years before the 1973 oil crisis.

“It’s not a particularly fast or thrilling beat, more plodding and methodical, but it’s getting the job done,” Josh Feinman, chief global economist of Deutsche Asset Management.
