The Office of Foreign Assets Control (OFAC), the US Treasury unit that administers American sanctions, removed 18 duplicate entries from its Specially Designated Nationals list on Monday 27 July as part of a modernisation exercise1. Every underlying designation stays in force2.
The SDN list is the register banks, insurers and shipping brokers screen against before they move money or accept cargo, and duplicates in it produce false matches that compliance teams then have to clear by hand. Removing them changes what a screening engine returns; it changes nothing about who is sanctioned.
The distinction is worth holding onto in a week when a delisting could be read as a concession. Treasury designated a network of Iranian firms linked to the oil trader Babak Zanjani under Executive Order 13902 on 24 July ; that was policy, aimed at named companies. Deleting duplicate rows three days later is maintenance on the register those designations sit in.
