UPDATE: Iran lets Iraqi oil tankers back through the Strait of Hormuz - the first concrete easing in weeks - but fresh US sanctions loom and Brent is still above $90

Who it hits first

• Chennai Petroleum and Savita Oil, which spend 95% and 86.3% of their costs on crude and crude-derived feedstock, get direct relief on their biggest bill
• Indraprastha Gas and Mahanagar Gas, which buy imported gas to top up their cheap domestic allocation, see that top-up cost fall
• ONGC and Oil India, which sell the oil they pump, lose the high price that a blocked strait was supporting
• Petronet LNG's import terminals can run closer to full as cargoes stop being rerouted or cancelled

Who may gain

• Refiners and lubricant makers whose single biggest cost is crude
• City gas distributors in Delhi and Mumbai, which had the strongest measured gains in both past easing episodes
• Petronet LNG on restored terminal throughput
• Paint, tyre and packaging makers further down the chain, whose petrochemical inputs track crude with a lag
