With the U.S. economy improving, the U.S. dollar has been falling recently. What are the factors of the dollar's devaluation? Chan Kung, Anbound’s chief researcher said the dollar’s devaluation this time has little to do with the economy, and neither is it has much to do with the speeches of the U.S. Secretary of the Treasury, Trump's attitude, the U.S. trade deficit, and the "strong" Renminbi. The two major reasons for the devaluation is the downward curve of the U.S. bond yield and the isolation of the U.S. due to the over-emphasis of "America First".
