How much do oil and gas prices rise if shipping halts?
Core argument: The authors estimate an $18/bbl real-time risk premium in crude prices based on a 15% weekend gain in retail prices, approximately matching their fair-value estimate of a six-week full halt in Strait of Hormuz flows.
Tanker traffic through the Strait of Hormuz--through which normally 1/5 of global supply for both oil and LNG flows--appears significantly disrupted as many shippers, oil producers, and insurers have shifted to a cautious wait-and-see mode amidst reports about damaged ships. Based on the 15% weekend gain in retail prices, we estimate an $18/bbl real-time risk premium in crude oil prices, which corresponds approximately to our estimate of the fair value effect of a six-week full halt in Strait of Hormuz flows (allowing for spare pipeline capacity use as a partial offset). This estimated impact moderates to +$4 if only 50% of the flows are halted for one month. However, oil prices can rise substantially more if the market demands a premium for the risk of more persistent supply disruptions. We see significant upside risk to prices from a potential sustained disruption of LNG supply through the Strait of Hormuz. In a scenario where flows halt for one month, we think it is likely that [European gas] and [Spot LNG] could approach 74 EUR/MWh ($25/mmBtu)--130% above current levels--a threshold that triggered large natural gas demand responses during the 2022 European energy crisis. We see limited upside risk to US natural gas prices.
