From Oversight to Omission: The OCC’s New Stance on Disparate Impact Liability

In this alert, Winston’s Financial Services Industry Group takes a closer look at the OCC’s new stance on disparate impact liability and its implications for the financial services industry.
The Office of the Comptroller of the Currency (OCC) announced on July 14, 2025, that it will cease supervising banks for disparate impact liability, instructing its examiners to “no longer examine for disparate impact.”[1] Accordingly, OCC examiners will not request, review, conclude on, or follow up on matters related to a bank’s disparate impact related risk, risk analysis, or assessment processes or procedures.[2] The OCC also removed references to disparate impact liability from its fair lending examination manual. 
This policy shift follows President Trump’s April 2025 executive order mandating the elimination of disparate impact liability across federal agencies and claiming that disparate impact liability forces companies to “engage in racial balancing to avoid potentially crippling legal liability.”[3] Given the Trump administration’s approach, the OCC’s policy shift is unsurprising. But the change means financial services companies should reconsider how they evaluate and address disparate impact risk, not only from the perspective of this revised federal regulatory lens, but also with the understanding that state attorneys general and private litigants will continue to pursue disparate impact claims as long as such claims remain legally viable. 
What does this mean to you and your clients?

What Is Generative AI?

Generative AI tools can create new content, such as text, computer code, images, audio, sound, and video, in response to a user’s prompt, often in the form of a short written description of the desired output. Generative AI tools are based on machine learning, trained using enormous amounts of data.[1] Generative AI tools are built on a system of inputs and outputs. First, the tool goes through a machine learning period whereby it is trained to generate predictive models and creative outputs through a large data set, often varied and diverse but tailored to the goal of the tool (i.e., customer service, generating scientific or marketing models, etc.). For in-house tools, this can be done with the company’s own data; for larger tools such as ChatGPT, this is done with the creator’s data set.[2] Once the tool has been trained, the individual user “inputs” a short prompt for the tool to synthesize and produce an “output.” Inputs are often retained on the servers controlled by the company that supports the tool, for monitoring of the tool’s performance and, in some cases, continued learning. The “outputs” are created by combining the machine learning during the training period with the inputs to produce an output.[3]...Read more
