OCC Challenges Applying California Climate-Disclosure Laws to Federal Banks
The OCC urged California regulators to clarify that national banks and federal savings associations are not subject to two state climate-disclosure laws, citing preemption, safety-and-soundness, burden, competition, and customer-access concerns.
What the OCC announced on October 29
Source publication date: October 29, 2026. The Office of the Comptroller of the Currency submitted a letter to the California Air Resources Board concerning two California climate-disclosure laws. The OCC urged CARB to clarify that national banks and federal savings associations are not required to comply. The announcement states the agency's legal and policy position; it is not by itself a final court ruling or a complete implementation guide for every entity.
- 01OCC asks CARB to exclude federal banks
- 02The letter raises preemption concerns
- 03Coverage is not resolved by the release alone
The OCC identified several legal and policy concerns
The agency said applying the laws to federally chartered banks would be inconsistent with OCC regulation and safety and soundness, impose undue burdens—particularly on smaller banks—disrupt customer relationships, and raise constitutional, preemption, and visitation concerns. The OCC also argued that coverage could reduce competition, increase prices, and limit access to financial services for California residents and Main Street businesses.
The issue can affect multiple parties differently
A bank, parent company, borrower, investor, vendor, or other business may have different obligations based on charter, entity, size, revenue, location, activities, corporate group, effective dates, and final regulatory interpretation. Even if a federal bank is excluded, it may still request climate, insurance, property, supply-chain, energy, or transition-risk information for underwriting, portfolio management, investor reporting, or other applicable requirements.
Practical borrower and investor takeaway
Identify which legal entities and reporting periods may be covered, assign responsibility, and preserve source data for emissions, energy, properties, insurance, vendors, and material risk disclosures where relevant. Track CARB guidance, OCC actions, litigation, and effective dates with qualified counsel. In financing discussions, ask which data the lender actually requires, how it will be used, and whether costs belong in the operating forecast. Do not assume the OCC letter automatically cancels a state obligation or changes credit terms.
Banks, borrowers, and investors with California exposure should monitor the implementation dispute, identify entity-specific reporting obligations, and maintain reliable emissions and risk data where required without assuming the OCC letter has resolved coverage.
