A KYC analyst receives a notification that the Office of Foreign Assets Control (OFAC) has updated its sanctioned entity and individual list. The analyst reviews the list and identifies a current customer. Which step should the analyst take first?

Upon identifying a confirmed match with an Office of Foreign Assets Control (OFAC) list, the immediate and legally mandated first step is to block or freeze the customer's accounts and any associated assets. This action is required to prevent the sanctioned entity from accessing or moving funds, thereby ensuring the financial institution's compliance with sanctions regulations. This immediate containment prevents any further prohibited transactions. Internal escalation and reporting to the appropriate compliance officer or MLRO follows the freezing action.

A. Report the issue to the Money Laundering Reporting Officer. This is a critical subsequent step, but the immediate legal obligation is to first freeze the assets to prevent their dissipation.
B. Form a sanctions committee to develop standard processes and procedures. This is a governance function. Such procedures should already be in place and are not an immediate response to a specific sanctions hit.
D. Contact the customer to request clarification. This is strictly prohibited as it constitutes "tipping off," which would alert the sanctioned party and is a serious regulatory violation.
