A U.S. official said the sanctions and blockade on Iranian ports will not be lifted until an agreement is signed on Friday [1].

The timing of the sanctions relief is critical because it links the immediate economic viability of Iran's maritime trade to the formal execution of a diplomatic deal. By maintaining the blockade, the U.S. is using port access as primary leverage to ensure the agreement is finalized without further delay.

The official said the U.S. intends to keep the restrictions in place as a prerequisite for the signing process [1]. This approach ensures that the terms of the agreement are fully accepted before any economic concessions are granted to the Iranian government [2].

"We will not lift the sanctions on Iran's ports until the agreement is signed on Friday," the official said [1].

The blockade affects the movement of goods and services through Iran's maritime gateways, creating significant pressure on the nation's trade infrastructure [2]. The U.S. position remains that the signing of the document is the only trigger for the removal of these specific measures [1].

Diplomatic observers are monitoring the situation to see if the Friday deadline will be met. The U.S. has made it clear that the sequence of events is non-negotiable: the signature must precede the lifting of the port sanctions [1, 2].

"We will not lift the sanctions on Iran's ports until the agreement is signed on Friday."

This development highlights a 'compliance-first' strategy by the U.S. government. By tying the lifting of the blockade directly to the act of signing on Friday, the U.S. minimizes the risk of providing economic relief without a guaranteed legal commitment from Iran. It transforms the port sanctions into a high-stakes bargaining chip for the final hours of the negotiation.
