A growing number of tankers carrying Iranian crude are reportedly sitting off eastern Malaysia, highlighting a slowdown in buying interest from China. The buildup points to a market where available cargoes are outpacing immediate demand, even as sellers offer steeper discounts.

The key pressure appears to be weak appetite from Chinese independent refiners, which have often been important buyers of discounted barrels. Their limited presence in the market is leaving more Iranian crude on ships for longer, creating a visible offshore stockpile near Malaysia.

The situation also suggests that price cuts alone are not enough to quickly clear cargoes. When refiners hold back despite cheaper offers, sellers may be forced to keep oil at sea while waiting for demand to recover or for trading conditions to improve.

For the broader oil market, the tanker cluster off Malaysia is a sign of soft regional buying and uneven crude flows into Asia. If Chinese independent refiners remain cautious, the offshore accumulation of Iranian oil could continue and keep pressure on pricing for those cargoes.
