IMF warns Trump trade tariffs could dent global economy as it upgrades UK outlook

New report upgrades outlook for UK economy with growth now forecast at 1.1% rather than 0.7%

• While the IMF is upbeat about global growth it knows where dangers lurk

The Washington-based organisation said tariffs trigger tit-for-tat trade wars that impoverish the economies involved in the dispute and the wider global economy.
