What happened

Crude just made its sharpest move in weeks. Brent futures jumped roughly 5% on Tuesday to trade above $75.50 a barrel, with US benchmark WTI up a similar 5% to around $72, as reported by NBC News and CNBC. Then it kept going: on Wednesday morning Brent rose as much as 3% more, with the September contract at $76.07 as of 04:00 GMT — the highest since June 23, per Al Jazeera. Two weeks ago oil had drifted all the way back to pre-war levels. That slide just reversed in about 36 hours.

Why it moved

Three things hit the market almost at once, and each one tightens expected supply.

• Attacks in the Strait of Hormuz. Three commercial vessels — including a Qatari LNG carrier and a Saudi oil tanker, per Yahoo Finance — were struck by projectiles in the strait. US, Qatari and Saudi officials blamed Iran. The strait is the world's most important oil chokepoint; roughly a fifth of global oil supply passes through it, so any doubt about safe passage gets priced instantly.
• The US revoked Iran's oil-sale licence. Last month, as part of a negotiated truce, the US Treasury had allowed Iran to sell its sanctioned crude until August 21. That waiver is now cancelled: no new purchases or loadings after Tuesday, and all transactions end by 12:01am EDT on July 17, per the Treasury statement cited by Al Jazeera. Iranian barrels the market was counting on are coming off the table.
• US strikes on Iran. US Central Command said it launched "powerful strikes" to impose costs for the shipping attacks, and Iran's military command vowed a "crushing response", per Business Standard. That raises the odds of a longer disruption, not a one-day scare.

The mechanism is simple: oil prices track expected barrels, not just current ones. Fewer Iranian exports plus a riskier Hormuz means traders pay more today for delivery tomorrow. MST Marquee's head of energy research told Al Jazeera that passage through the strait could stay below 50% of pre-war levels for months.

Who it touches

India imports most of its crude, so this lands hard at home — Indian markets opened lower on Wednesday, with the Nifty down about 0.56% at 24,261 by mid-morning and oil & gas the worst sector, per Business Standard.

• Hurt: Indian oil marketing companies (HPCL, BPCL, Indian Oil) — they buy crude and can't always pass on higher costs; HPCL and BPCL were among Wednesday's top losers. Also airlines (IndiGo), paints (Asian Paints, Berger) and tyre makers, where crude is a core input.
• Helped: upstream producers like ONGC and Oil India, which sell crude at prices linked to Brent; US shale producers; and LNG shippers able to avoid the strait.
• Watch the rupee: costlier oil widens India's import bill and tends to pressure the currency, which feeds inflation beyond fuel.

What to watch

The one thing that would flip this move: a credible de-escalation that reopens the strait to normal traffic — that's what dragged Brent back to pre-war levels earlier, and it could do so again just as fast. On the other side, the July 17 licence deadline is now a hard date; if Iranian barrels actually stop flowing then, today's price may look cheap. Gold and silver, notably, fell on Wednesday (down 0.99% and 1.87% per Business Standard) — this is an oil-supply story, not yet a broad flight to safety.
