Global oil markets face mounting pressure as tankers that departed before the US-Iran conflict now arrive with minimal follow-on shipments. Goldman Sachs data reveals Asian countries excluding China hold only about a month's worth of oil stockpiles, leaving them vulnerable to supply disruptions. South Korea, India, Malaysia, and Singapore are experiencing immediate impacts as their heavy dependence on Gulf crude becomes a liability.

Governments across Asia have begun implementing demand-containment measures including remote work policies, air conditioning restrictions, and public transport incentives. Australia faces secondary effects, importing refined products from Asian hubs now restricting exports to domestic markets. The situation highlights how quickly energy security can shift from theoretical concern to practical crisis when supply chains are disrupted.

Should the strait remain closed, the market will eventually rebalance, but at a cost of approximately 10 million barrels per day less than current consumption - comparable to the entire drop during the first year of the Covid-19 pandemic. This creates a two-tier challenge: geographic vulnerability initially, then affordability becomes the primary determinant of access. Wealthy nations like Australia can likely outbid others for scarce cargoes, but even rich countries may need to prioritize strategic users like healthcare systems over consumer markets.
