The oil licence Trump finally signed

GL X's narrow scope (oil alone, 60 days, no frozen-assets release) reflects three structural constraints in Washington's position.

First, the Islamabad MOU was published in outline only, and its nuclear commitments, per US officials speaking to CNN, exist as verbal side-deals rather than treaty text. OFAC cannot issue broad relief against a document whose binding terms are not in writing.

Second, the US Treasury's IRGC designation framework, in place since 2007 under Executive Order 13382, prohibits dollar payments to entities the IRGC controls. Any instrument broader than GL X would require a formal designation revision, which carries its own congressional-notification requirements under IEEPA.

Third, GL X also quietly amends Russia-related General License 134, linking the Iran oil instrument to the parallel Russia sanctions track. That dual-ledger linkage constrains how far any single Iran relief instrument can go without triggering Russia-policy objections inside the administration.

GL X is de-escalatory in intent but the 60-day ceiling contains its own escalation risk. If the window closes without a successor instrument on 21 August, Iran's oil sector reverts instantly to full sanctions exposure.

The PGSA fee schedule and Shetab-Mir Stage 3 completion both fall within the same window, meaning the August expiry will arrive with Iran's parallel infrastructure complete rather than nascent. A cold snap-back on 21 August would be harder to enforce than the original sanctions, not easier.
