Correction — 22 October 2026: This guide replaces unsupported claims about inevitable bond and currency reactions, fixed geopolitical price premiums and predictable trading outcomes. The figures below have explicit historical reference periods. They do not describe live shipping conditions or establish whether the strait is currently open, closed or operating normally.
Keep the denominator and date attached to the headline
The EIA’s 16 June 2025 chokepoint analysis estimated 2024 oil flows through Hormuz at about 20 million barrels per day, equivalent to roughly one-fifth of global petroleum-liquids consumption. Its share of seaborne oil trade was larger. Those percentages use different denominators; they are not interchangeable.
The IEA’s February 2026 factsheet describes approximately 20 million barrels per day of crude and products passing through in 2025. It estimates 3.5–5.5 million barrels per day of capacity potentially available to redirect crude via Saudi Arabia and the UAE. The factsheet cautions that rerouting logistics had not been robustly tested at substantial volumes. These are dated estimates, not guaranteed emergency deliveries.
Separate traffic, production and delivered supply
A tanker delay is not automatically an equal-sized production loss. Cargo can wait, inventories can change, routes can change, and customers may receive deliveries later. Equally, a production-capacity estimate does not establish that the output can reach the intended buyer. A useful update specifies which quantity is being discussed and over what period.
For a purely hypothetical balance, assume that 10 million barrels per day of normal deliveries are disrupted for five days. The gross delayed volume is 50 million barrels. If a separately verified alternative provides 2 million barrels per day for all five days, that offsets 10 million barrels, leaving 40 million before considering inventories or demand changes. This is arithmetic under stated assumptions, not an estimate of an actual event or a forecast of the oil price.
Check four operational questions
- What changed? Distinguish a statement, a navigation restriction, a delayed loading, and a measured reduction in completed voyages.
- Which cargo? Crude, refined products and LNG are different markets. A crude pipeline cannot simply substitute for an LNG vessel.
- For how long? A flow rate needs a duration before it becomes a volume shortfall. A temporary delay and a persistent loss have different implications.
- What can actually be rerouted? Identify spare operational capacity rather than total design capacity, and account for the ports and onward transport needed.
Why an importer’s cost needs a currency calculation
Use an illustrative barrel priced at $80 and an exchange rate of 1,300 local-currency units per dollar. Its converted price is 104,000 local units. If the dollar price rises to $88 and the exchange rate rises to 1,365, the converted price becomes 120,120: a 15.5% increase. The 10% commodity move and 5% currency move compound. Freight, insurance, taxes, contract terms and hedges are excluded from this example, so it is not a company’s actual import bill.
A currency move can also offset part of a commodity move. The direction must be measured rather than assumed from the geopolitical headline. To compare actual costs, use matching dates and the relevant contract or invoice basis.
A bond move is not a verdict on the whole event
The earlier guide presented rising yields as proof of a serious inflation shock and falling yields as proof of a contained growth shock. That binary test was too strong. A single yield observation cannot identify all the expectations behind it, and markets can respond to unrelated information during the same session. State the yield change in basis points, identify the instrument and time interval, and separate it from any proposed explanation.
The same discipline applies to equities. An energy producer’s exposure depends on its operations, sales terms and other costs; a higher oil quote does not guarantee its share price rises. A broad index also combines businesses with different exposures. The original universal sector-trade recommendation has therefore been removed.
A usable format for the next update
Record the source publication date, the underlying observation period, the affected cargo and route, the measured quantity, and the uncertainties. Then show the price observations separately. If only rhetoric changed, describe rhetoric. If verified shipments changed, state the measurement. Avoid converting either into an unsupported probability of closure or a fixed dollar premium.
