Both US banks and utilities are considered critical infrastructure under Executive Order 13636 of 2013. The government is charged with ensuring their resilience and availability to maintain a stable society (in the face of cyber threats).

If politics is a risk to stability (I know at least one fortune 100 finance company that does have it in their risk register) then this Trump executive order against de-banking is aligns with the former one from the Obama administration.

A defense against de-banking is a bi-partisan win.
