Oil climbed above $110 a barrel in London trading, hitting a three-week high, as markets held their breath waiting for Washington's response to a proposal from Tehran aimed at ending the war and reopening the Strait of Hormuz.

Why the Strait of Hormuz Matters So Much

The Strait of Hormuz is the narrow waterway between Iran and Oman through which roughly one-fifth of the world's oil supply passes every day. Any closure or threat to shipping there sends immediate shockwaves through global energy markets, because there is no easy alternative route for most of that volume.

Tehran's proposal, the details of which have not been made public, appears to have introduced the possibility — however uncertain — that the strait could reopen to normal traffic. That prospect alone was enough to push traders into a cautious wait-and-see position rather than driving prices sharply higher.

What the Market Is Pricing In

The move above $110 reflects ongoing war risk premium baked into crude prices. Traders are not yet pricing in a resolution; they are pricing in uncertainty. If Washington rejects the proposal or talks stall, the risk of prolonged disruption to Hormuz traffic remains, which would likely push prices higher still. A credible agreement, on the other hand, could bring swift relief to oil markets and ease pressure on fuel costs globally.

For India, the stakes are particularly direct. India is one of the largest importers of crude oil from the Gulf region, and much of that supply transits through the Strait of Hormuz. Elevated oil prices feed through quickly into fuel costs, inflation, and the current account deficit — all pressure points for the Indian economy right now.

The fact that prices have risen to a three-week high without a clear escalation suggests the market is assigning meaningful probability to further disruption. The US response to Tehran's proposal is now the single most watched variable in global energy markets.

Watch for: any official statement from Washington on the Iranian proposal, any change in shipping activity near the strait, and weekly US crude inventory data, which could amplify or dampen the price move in the near term.
