PARIS: Global economic growth has peaked out in the face of rising trade frictions and emerging market turbulence, the OECD said, trimming its earlier outlook. The world economy is on course for growth this year of 3.7% this and next year, up from 3.6% last year, said the Organisation for Economic Co-operation & Development (OECD). In its last economic outlook in May, the Paris-based policy forum had forecast growth of 3.8% this year and 3.9% in 2019, but it said in an update yesterday that growth had peaked since those last projections were made.
