The new measures grant countries an unspecified deadline to terminate Iran-related activities or face punitive U.S. intervention. By broadening the reach of the Office of Foreign Assets Control (OFAC), the Treasury now claims authority to penalize foreign persons providing services to Iran’s digital asset, technology, gold, and shipping sectors. These designations specifically target brokers and shadow-fleet operators across the UAE, Hong Kong, Singapore, Switzerland, and Europe that funnel revenues to the IRGC-Quds Force.

Beijing remains the focal point of this pressure campaign, as it currently absorbs over 80% of Iran’s seaborne oil. While Washington has bypassed major Chinese banks for now, the effect of the blockade is already visible in import data, which dropped from 823,000 barrels per day in July to 534,000 in August. Market data shows Iran’s offshore crude stocks are depleting rapidly, falling from over 100 million barrels in mid-July to roughly 83 million, with only a small fraction of floating storage remaining unsold near Singapore.

Oil markets reacted with a retreat as traders secured profits ahead of the announcement. Brent crude dropped 2.56% to $91.97, while WTI fell 2.58% to $84.81 by Monday afternoon. The decline marks a cooling period for energy benchmarks that had rallied more than 5% in the previous week in anticipation of the administration’s strategy.
