Chinese oil trader Unipec diverted a supertanker away from Shandong after new U.S. sanctions complicated discharge plans, underscoring fragility in crude logistics under tightened compliance. The diversion may spur demurrage, prompt rerouting costs and influence regional benchmarks. Traders said supply chains are recalibrating as sanctions risk interacts with weak prices and refinery runs. Market focus remains on whether diversion becomes systemic or isolated, affecting Asia’s import mix, shipping day rates, and refinery margins over coming sessions.
