The British economy will grow by 1.0% in 2017, said the OECD as it published revised forecasts.
In its earlier forecasts in June, before the referendum, it had projected the economy would grow by 2.0%.
Growth in 2017 is likely to be “well below the pace in recent years and forecasts prior to the referendum,” the OECD said.
In addition, “uncertainty about the future path of policy and the reaction of the economy remains very high and risks remain to the downside.”
The weaker outlook for Britain, the second-biggest economy in the European Union, will also push down global output, which is stuck in a “low-growth trap,” the organisation warned.
Global growth is seen at 2.9% this year, rising to 3.2% in 2017, the OECD said, trimming both forecasts by 0.1 percentage point.
The effects of Brexit are offset by a “gradual improvement in major emerging market commodity producers,” according to the OECD.
However, while the Brexit impact on the rest of the euro area has been “modest” so far, the OECD said the spillover will result in “more negative effects” next year.
The organisation downgraded its 2017 forecast for the 19-nation zone by 0.3 percentage point, projecting growth of 1.4% after 1.5% this year.
The key to avoiding significant economic problems will be quickly sorting out Britain’s trading relationships with its partners, the OECD added. - AFP
