From the article:
Outside of legislative action, who Trump appoints to the Fed will play a significant role in how the institution operates going forward. In particular, there is great focus on the vice chair of supervision, a position created specifically to monitor the Fed’s expanded powers as a financial regulator.
That position was created as part of the Dodd-Frank financial reform law as a focal point for new regulatory powers, but President Obama never nominated someone to fill it. That allows Trump to make a significant mark on how the Fed operates as a regulator with just one selection.
