The World Trade Organization cut its forecasts for global goods trade on Wednesday after quarterly growth turned negative, with trade shrinking by an average of 0.7% in the first two quarters of this year.
The WTO sees world trade growth of 2.8% this year and 3.9% in 2016, revised down from the forecasts it made in April of 3.3% and 4.0%, respectively.
Risks, including a potential US interest rate rise and further slowing in developing economies, are "firmly on the downside", the WTO said in a statement.
