Strait of Hormuz Closure: Daily Revenue Flows and Price Impact

The immediate financial impact is quantified by the strait's near-total shutdown. Vessel traffic has collapsed to roughly 4 per cent of pre-war levels, with only a handful of ships transiting daily. This effective closure has severed the flow of goods that normally pass through the waterway, where 20 per cent of the world's oil and gas transits.

The daily revenue loss is stark. Iran, which relies on oil exports for a major portion of its income, is losing an estimated $105 million per day in oil revenue at current prices. This represents a direct and severe blow to its state coffers, cutting off a critical cash flow.

For the world's largest oil importer, the cost is even more acute. If oil prices climb to $150 per barrel, China would face an additional daily expense of $560 million. This figure is derived from its 6.5 to 7.5 million barrels of oil per day imported through the strait, which accounts for 40-45% of its total supply. The price shock is not a future possibility but a present financial pressure.

The Price Surge and Rerouting Costs

The immediate market impact is a severe price shock. Crude oil prices have surged nearly 47% this month due to the reduced supply. This is not a distant threat but a present financial reality, with the cost of a barrel of oil now climbing sharply.

The shockwave spreads to industrial materials. Polypropylene, a key plastic feedstock, jumped 24%, while aluminum increased 10%. These spikes directly feed into manufacturing costs for everyday goods, from packaging to electronics, as companies face higher input prices.

At the same time, the physical rerouting of ships adds a new flow of money to the global economy. Longer transit times and higher freight costs are driving up shipping and marine insurance expenses. This creates a double cost pressure: manufacturers pay more for materials and more to get them.

The Flow of Money and Key Catalysts

The critical catalyst is the duration of the closure. If the strait remains shut, manufacturers will shift from a waiting pattern to active mitigation, further straining global supply. This transition is already underway, with companies bracing for higher transportation and materials costs as they seek alternatives.

Major Asian economies face rising energy costs and production pressures, reshaping the balance of winners and losers. China, India, Japan, and South Korea are the first to feel the impact, with daily cost increases ranging from $224 million to $560 million. This directly threatens their industrial competitiveness and domestic inflation, creating a powerful incentive to resolve the crisis.

A new flow of money is emerging for Iran. The regime has begun charging transit fees on some commercial vessels passing through the strait, representing a direct revenue stream. This creates a perverse incentive to maintain the chokepoint's strategic value while generating cash, complicating diplomatic efforts to reopen it.
