What is the reported US–Israel plan on Iran oil sanctions?

According to Japanese media, Washington and Israel aim to tighten pressure on Tehran by targeting crude exports to China, which take over 80% of Iran’s shipments. Measures discussed include stricter scrutiny of routes, sanctions on shippers or insurers, and possible third-country tariffs. Enforcement details and timing remain uncertain.

How could this affect oil prices and Japan?

Markets may add a risk premium even before any cargo is halted. Higher freight and insurance could widen Brent-Dubai spreads and lift Asia benchmarks. Japan could see higher import costs flow into the Japan Crude Cocktail with a lag, affecting utilities, airlines, chemicals, and household energy bills.

What signals would show the policy is being enforced?

Look for more detentions or inspections of Iran-linked tankers, changes in ship-to-ship patterns, insurer or classification society notices, and US Treasury guidance. Chinese port data, weaker discounts on Iranian barrels, and tighter Brent-Dubai time spreads would also suggest impact on flows and risk premium.

How does this relate to Iran nuclear talks?

The Feb 17 talks could set the tone for security and energy issues. Tougher positions might support tighter measures, while dialogue could keep enforcement gradual. Markets will react to any guidance on exceptions, timelines, or coordination with China, which heavily influences Iran’s export channels.
