The dollar has been under pressure this week, as riskier currencies benefited from increased optimism over a string of Covid-19 vaccines news reports and hopes for a more stable period in politics.

"When looking at how economies have rebounded in the July quarter, the United States grew and made a strong rebound. In a scenario where vaccines becomes gradually available next year and economies return to normal, the will probably be one of the most resilient among developed countries. And I think that will create a dollar-favourable environment," he said.
