What Visa Inc. told the SEC could break it.
Visa's largest single exposure is legal: its long-running U.S. interchange litigation still had roughly $39.4 billion of estimated interchange fees at issue in unresolved damages claims as of October 1, 2025 (down from about $49.6 billion two years earlier). Most of the rest is regulatory pressure on how its network operates around the world — rules on transaction routing and on-shore processing in markets like Thailand, Mexico and Brazil that can force it to lean on third-party processors or even support rival networks — and the geopolitical fallout of sanctions, having suspended its Russia operations in March 2022 and given up that revenue entirely. Underlying it all is heavy international concentration: about 61% of fiscal 2025 net revenue ($24.4 billion of $40.0 billion) came from outside the U.S., subject to local regulation and currency swings.
4 self-disclosed vulnerabilities, pulled from its own filings, each in the company’s words, with the source. This is the risk register almost nobody reads.
In its own words
What could break it.
Regulatory & policy
- transaction-routing / on-shore processing mandates (Thailand, Mexico, Brazil)medium
In countries where Visa cannot manage end-to-end processing (e.g. Thailand, Mexico) it depends on clients/third-party processors, and regulations on transaction routing, on-shore processing, and network-rule pre-approval (e.g. Brazil) could force Visa to support rival networks or share IP.
“Due to our inability to manage the end-to-end processing of transactions for cards in certain countries (e.g., Thailand, Mexico), we depend on our close working relationships with our clients or third-party service providers to ensure transactions involving our products are processed effectively.”
SEC filing →As of 2025 - Russia operations suspension due to sanctions — loss of Russia revenuemedium
Visa suspended its operations in Russia in March 2022 due to economic sanctions and no longer generates domestic or cross-border revenue from Russia; war in Ukraine and Middle East instability create further regional exposure.
“In March 2022, we suspended our operations in Russia due to economic sanctions imposed on Russia, impacting Visa and its clients. As a result, we are no longer generating revenue from domestic and cross-border activities related to Russia.”
Litigation
- U.S. interchange MDL — ~$39.4B in interchange fees at issuehigh
Visa's U.S. covered interchange litigation (Interchange MDL) involved approximately $39.4 billion of estimated interchange reimbursement fees at issue in unresolved damages claims as of October 1, 2025 (down from ~$49.6B in 2023).
“The estimated interchange reimbursement fees at issue in unresolved claims for damages in the U.S. covered litigation was approximately $49.6 billion as of October 1, 2023 and was approximately $39.4 billion (1) as of October 1, 2025.”
