"We expect a broad dollar decline to continue, supporting emerging market FX (despite local coronavirus issues) and see euro/dollar at $1.15 in 3 months," said Lars Sparres? Merklin, senior FX analyst at Danske Bank, in a note to clients.
"This continues to be a recurring observation, with markets not being weighed down by the current host of problems with coronavirus in EM and some U.S. states, not least the likely still-weak current earnings."
Merklin added that the market's focus is the direction rather than the level of economic activity, being supported by fiscal and monetary policy.

A weekly gauge of consumer confidence in Australia has dropped after a spike in infections in Melbourne and that could be echoed in the United States, where the magnitude of the outbreak is much larger, he noted.
