Dollar devaluation: A clear relief valve for US economic policy

As the FED continues to push for policy normalisation, it is unable to do so and maintain its mandate for keeping stock propped up (more formally known as the 'wealth effect' or explicitly acted upon in the eyes of 'ensuring market stability').

A pricy dollar does not economically benefit the US, for example: with much exposure to energy junk debt through its banks, the devaluation of the Dollar helps support the revaluation of Oil despite the continued glut. This helps stabilise various risks in the economy which poise risk to policy normalisation.
