The OCC tells California its climate laws should not reach national banks

On October 29 the OCC asked the California Air Resources Board to confirm that national banks and federal savings associations need not comply with two state climate disclosure laws. The agency cited preemption, visitation and the cost to smaller banks.

OCC letter to CARB
Letter
No formal preemption order

The OCC sent a letter to the California Air Resources Board on October 29 about two California climate disclosure laws. It asked the board to clarify that national banks and federal savings associations are not required to comply. The release says the laws “would be inconsistent with OCC regulation” and that their application to banks “may well run afoul of the legal framework for preemption and visitation.”

The OCC listed several concerns. It said the laws would put an undue burden on smaller banks and could harm California customers and their banking relationships. It also raised constitutional concerns under the Supremacy Clause. The agency warned that the result could be less competition, higher prices and reduced access to financial services in California.

A letter, for now

The OCC did not issue a formal preemption determination. It sent a letter and said that “the agency will continue to monitor state law developments nationwide and act where appropriate.” The release does not name the two laws, and the full letter is posted as a PDF. State-chartered banks are outside the letter’s reach, so their obligations depend on the laws themselves.

Preemption is now being argued in letters before it is argued in court. National banks should keep the letter on file.
What this means for your bank
  • National banks with California operations should file the OCC letter with their compliance analysis of the two laws and track CARB’s reply.
  • State-chartered banks should not rely on the letter. Confirm with counsel whether either law reaches you.
