• Tanker voyage times from the Persian Gulf to Asia, taking 28–55 days, are keeping oil inventories under pressure even after any reopening of the Strait of Hormuz.
  • Rerouted vessels via the Cape of Good Hope could take 1–2 months to fully resume normal operations, prolonging supply chain disruptions.
  • Global oil prices remain elevated as transport costs rise and inventories struggle to rebuild.

Slow Rebalancing Ahead

Tanker delays from the Persian Gulf to key Asian markets are extending the oil market's rebalancing process, according to Rabobank strategists. Fully laden shipments to India, China, South Korea, and Japan take 28–55 days, meaning that even if the Strait of Hormuz reopens, inventories will remain under pressure for weeks.

Rerouted vessels via the Cape of Good Hope could require an additional 1–2 months to fully restart normal operations after any pause in hostilities. “The lag in flow normalization is a critical factor,” one shipping analyst said. “Backlogs and restart dynamics mean the market won't snap back overnight.”

Geopolitical Tensions Persist

The situation underscores the vulnerability of the Strait of Hormuz as a critical chokepoint. Even as diplomatic efforts continue, the risk of further disruptions keeps shipping costs high and insurers cautious. “We're seeing a structural shift in how tankers are routed,” a Singapore-based trader noted. “Every day of delay adds to the cost burden for refiners.”

Implications for Asian importers are significant. With inventories already low, higher transport costs are feeding into refined product prices. Producers face scheduling penalties and higher insurance premiums, while consumers brace for potential price pass-throughs.

Outlook

In the near term, tight tanker availability and elevated freight rates will likely sustain oil quotes until flows normalize. A gradual rebalancing is expected if tensions ease, but the tempo will remain uneven. “Think of it as a river with multiple dams,” one strategist said. “Even if a dam opens, the downstream takes time to settle.”
