UPDATE: Iran's draft Hormuz plan bars US and Israel-linked vessels and fines violators 20% of cargo value; Brent jumps 3.8% to $82.49

Who it hits first

• Chennai Petroleum and Savita Oil buy crude as their main input (95% and 86.3% of cost) and cannot raise selling prices as fast, so their margins get squeezed straight away.
• The three state fuel retailers - Indian Oil, BPCL and HPCL - pay more for crude while pump prices stay effectively administered, squeezing what they earn on every litre sold.
• IndiGo pays more for jet fuel, which is 28.3% of what it spends to fly.
• Paint makers Asian Paints and Berger pay more for the crude-derived chemicals that make up 40% and 32.5% of their costs.
• Britannia has already told investors that Middle East conflict costs pushed its June-quarter profit below expectations, so the shock is showing up in real company results, not just forecasts.

Who may gain

• Great Eastern Shipping owns oil tankers; when a waterway carrying a fifth of the world's oil becomes risky, cargo sails further and insurers charge more, so tanker owners collect higher daily rates.
• ONGC and Oil India pump crude out of the ground and get a higher price per barrel - though India's history of taxing oil windfalls has capped how much of that reaches shareholders, and neither actually rose in the last crude spike.
• Refineries generally earn more profit per barrel during a supply scare, and companies holding crude bought cheaply book a gain on those stocks.
