Which database lists all merchants termined for cause?

The Combined Terminated Merchant File is the correct answer because it specifically contains a list of merchants that have been terminated for cause, which means they were dropped from their payment processing agreements due to violations or other issues that warranted such action. This database is crucial for payment processors and acquirers as it helps them avoid high-risk partnerships and protect themselves from potential fraud or financial losses by ensuring that they are not working with merchants known for problematic behavior.

In contrast, the Combined Warning Bulletin is typically used to alert processors about potential risks or issues with specific merchants but does not catalog those terminated for cause. The Commercial Relationship and Commercial Credit databases do not focus on merchant terminations at all; instead, they relate to broader aspects of business relationships and credit evaluations, making them unsuitable for this specific inquiry.
