Iran has opened talks with three Japanese firms on resuming crude imports for the first time since 2019, two Iranian and Western sources told Reuters1. The purchases would run under the temporary United States sanctions waiver that took effect on 22 June and expires on 21 August, the one live document tied to the 60-day peace deal. Japanese buyers have asked Washington for a longer waiver before committing, because a tanker sailing from Iran to Japan spends much of the 60-day window at sea.
A senior Japanese refiner told Reuters that insurance, not politics, is the single biggest obstacle2. Every cargo needs protection-and-indemnity (P&I) cover, the marine liability insurance that pays out when a tanker spills, collides or is seized, and that cover has been frozen or priced at war rates since this conflict's first week. Washington has licensed the trade through 21 August, yet none of the three firms will load a barrel until that cover clears. A licence removes the legal bar; it does not compel a London or Asian underwriter to write the policy, and the underwriters have not returned at commercial rates.
That gap is the whole story. Iranian crude has been sailing freely for weeks, an estimated $3.5 billion of it since mid-June, yet Trump demanded cheaper petrol and signed nothing new on Iran, and Treasury reached for pre-war authority to keep its existing sanctions moving, the very framework Japan is now testing. Japanese buyers are asking for a longer window before they load, which means they are pricing in the risk that a cargo booked today arrives after the legal cover has lapsed, a timing mismatch the transit distance makes acute.
If the insurance market stays shut, the waiver produces headlines and no cargoes, exposing a form of sanctions relief that cannot function without underwriting capacity. If a Japanese refiner does commit, it widens Iran's buyer base beyond China and sets a precedent other Asian importers will watch closely.
