**Summary**: US Treasury Secretary Bessent says new bank sanctions on Iran will be announced this week and next, alongside comments that he has discussed Iran cooperation with China and that Hormuz will be ‘bypassed’ in two years. Markets may read this as preparation for tougher enforcement on Iranian oil flows, lifting the geopolitical risk premium in crude.

## Detail

1) What happened: The US Treasury Secretary stated that the United States will announce new bank sanctions on Iran over the next two weeks and that he has held private discussions with China on cooperation regarding Iran. He also remarked that the Strait of Hormuz would be “bypassed” within two years as oil flows transition to land pipelines, and characterized Iran as trying to use Hormuz as a chokepoint. These comments come amid an already tense US–Iran environment, with recent tanker attacks and threats around Hormuz.

2) Supply-side and demand effects: Additional US sanctions on Iranian banks can materially affect Iran’s ability to receive payment and clear transactions for oil exports, particularly if they target financial intermediaries used to circumvent existing restrictions. While Iran has been exporting an estimated 1.5–2.0 mb/d in recent years via gray channels to China and others, stricter financial enforcement could constrict that flow by several hundred kb/d if Beijing and smaller traders grow more cautious. The mention of US–China coordination over Iran is critical: even a modest tightening of Chinese compliance could have an outsized impact on Iranian export volumes and insurance/shipping arrangements. The two-year horizon for bypassing Hormuz is more of a strategic signal than an immediate factor, but it implies US willingness to reduce systemic dependence on Gulf maritime routes, keeping geopolitical risk premium elevated in the interim.

3) Affected assets and direction: Brent and WTI are biased higher on expectations of tighter effective supply from Iran and an intensified sanctions/grey market crackdown. Dubai/Oman benchmarks and Middle East sour grades may see stronger support relative to Atlantic Basin crudes if Iranian barrels become less accessible to Asian refiners. Tanker equities in the dirty segment could benefit from increased route inefficiencies, while risk premiums on Gulf shipping and war risk insurance stay elevated. The Iranian rial remains under pressure; EM FX exposed to higher oil import bills (e.g., INR, TRY, PKR) could face incremental headwinds.

4) Historical precedent: Each meaningful ratchet-up in Iran-related financial sanctions (2011–2012 SWIFT measures, 2018–2019 US withdrawal from the JCPOA) produced multi-percent gains in crude benchmarks as markets priced in export losses of 0.5–1.0 mb/d. Market reaction this time will hinge on how sweeping the bank designations are and whether China visibly cooperates.

5) Duration: The signaling effect is immediate; price impact could unfold over weeks as details emerge and physical export data adjust. If enforcement is robust and sustained, the supply effect and associated risk premium could persist for months to years, barring a parallel diplomatic de-escalation or offsetting increases from other producers.
