Another wave of risk aversion swept through the foreign exchange market again on Wednesday, causing investors to favour the safe-haven US dollar at the expense of most other major currencies.Chair of the Federal Reserve Jerome Powell had very little positive to say regarding the US economy during his speech yesterday. As we had anticipated, Powell ruled out the possibility of the Fed cutting interest rates into negative territory, although he did warn that additional measures may have to be taken in the coming months to shield the economy. He warned the market about significant downside risks and long-term economic harm caused by the virus outbreak, noting that the recovery would be a gradual one.We’ll continue to receive evidence of this aforementioned hit to the US economy in this afternoon’s initial jobless claims data, which remains one of the most important releases on the economic calendar. While we are seeing an easing in the number of new weekly jobs shed, the pace at which new claims has slowed has been a much more gradual one than hoped. With no real job protection schemes in the US to speak of this is likely to remain the case in the coming weeks - a development that is unlikely to help the dollar’s cause, in our view.Aside from today’s jobless claims, we look ahead to tomorrow’s US retail sales data for April. An avoidance of sales falling by a fresh record amount would be a major surprise.
