Overview
- Ship-tracking analysts reported that tanker-based floating storage off Malaysia and Singapore was drawn down to zero by mid-October, ending the pool of crude Iran used to supply Chinese refiners.
- U.S. Central Command says the blockade has denied Iran roughly $25 billion in oil revenue, which officials say limits Tehran's ability to replace weapons and fund wartime production.
- Chinese independent refiners that relied on discounted Iranian crude have shifted purchases to Brazil and West Africa, reshaping Atlantic Basin flows and lifting premiums for those grades.
- Non-Iranian Gulf crude shipments have recovered to about prewar volumes under U.S. naval protection through the Strait of Hormuz, which has eased but not eliminated price and transport costs.
- Oil sales make up about 30 to 40 percent of Iranian government revenue so the loss has sharp fiscal impact, is worsening currency and inflation pressures, and increases incentives for Tehran to use energy disruption as leverage.
