Iran Faces Trilemma as US Blockade Enters Third Phase

The US-Iran war has entered its third phase, with Tehran facing a trilemma: endure, escalate, or negotiate. The blockade imposed by Washington is making it increasingly expensive for Iran to maintain the status quo.

Iran's crude exports have fallen to 248,000 barrels per day (kbd) in August, while non-Iranian crude flows through the Strait of Hormuz have increased. In contrast, Iranian oil loadings at Kharg Island have decreased significantly, and loaded barrels are trapped within the blockade zone.

The blockade is also affecting Iran's petrochemical exports, which have declined by 63% since early 2026. Food imports are under pressure, with corn, soybean, and wheat imports below their five-year range. The UAE's decision to halt trade with Iran threatens another important import channel.

Tehran is likely to withstand the blockade for several more months, but doing nothing carries costs beyond economics. Iranian officials have long maintained that if the country cannot export oil, its neighbors should not be able to either. The recovery in Gulf exports undermines this deterrence narrative and risks looking like weakness to the domestic audience.
