Iran parliament speaker Ghalibaf on Sunday called for a nationwide campaign to reduce natural gas consumption by at least 10% as officials warn of shortages ahead of winter.

Mercuria, one of the world's largest commodity traders, has sued the 282‑year‑old Baltic Exchange; the UK High Court will hear the case on Monday. The dispute centers on whether the Baltic should have continued publishing its flagship tanker route benchmark TD3C for voyages via the Strait of Hormuz after US and Israel opened hostilities with Iran. Mercuria says voyages fell sharply and Iran declared a blockade, and argued the Baltic should have suspended TD3C; it initially alleged losses of "hundreds of millions of dollars" but amended its filing to drop monetary damages and now seeks declaratory relief that publications since early March are invalid. The Baltic Exchange says short‑term inactivity on a route is not uncommon, brokers continued to provide rates, and warns a Mercuria victory would have "chaotic market‑wide consequences" and could force the unwinding of hundreds of trades. TD3C underpins pricing and hedging for billions of dollars of freight derivatives.
