Due to the FED's unprecedented actions to help backstop a depression caused by a forced governmental economic lockdown the USD is losing purchasing power rapidly. Sure, people will argue that due to the global sovereign demand of USD relative to other global currencies, that there is still some relative strength. The thing is, the FED has taken the most aggressive action in comparison to every other central bank in the world at the moment. Currently, we are in a deflationary environment due to a simultaneous supply & demand shock. Why does this matter? If the USD were to remain elevated, this would hinder US exports due to currency conversions (foreign firms' margins decrease). So to maintain and/or increase global import/export trends, a weaker USD is a benefit for the United States from a supply/demand perspective. China knows this is the case due to global FX markets, look at the price of the Yuan since September 3, 2019. Their government caps levels they want their currency at, and have been reportedly called out for manipulating their currency via their central bank. Not only is it a matter of maintaining economic growth in the United States, it's a matter of maintaining global currency demand away from China.
