The Australian dollar benefited from not only the lift in bond yields but also gains in commodity markets, jumping as high as 69.38 US cents, a level last seen in late July. The Chinese yuan increased to four-month highs as the prospect of tariff cuts negated the need for a weaker currency. The euro also fell sharply against the pound, hitting a low of 82.78 pence, its weakest level since July 2016.
