Oil's sharp drop takes some heat off inflation and gives a tailwind to anything that burns fuel or uses it in products.

Why the price fell

Tensions in the Middle East easing removes the fear premium that had been baked into crude. With less chance of supply shocks, traders sold futures and WTI slid more than 7% to the $83-84 range. Brent followed. That's the direct cause-and-effect: lower geopolitical risk equals lower oil price.

Who feels it first

• Helps: Oil marketing companies (IOC, BPCL, HPCL) see better margins on fuel sales; airlines get lower jet fuel costs; paint, tyre and chemical makers pay less for feedstock; broader risk assets like equities get a mild boost as inflation worries cool.
• Hurts: Upstream producers such as ONGC face lower realisation on every barrel they pump.

What would reverse it

Any fresh escalation in the region that re-introduces supply risk would quickly push prices back up. Watch headlines on that front more than the daily oil print itself.
