Global oil prices rose Monday after Iran signaled that the Strait of Hormuz would not reopen quickly [1].

The uncertainty threatens one of the world's most critical energy arteries, where any prolonged closure could trigger severe global supply shocks.

Brent crude futures reached $83.54 a barrel at 0643 GMT [3]. Prices for the day increased by nearly two% [2]. Market analysts said the upward movement reflects cautious trading as Iran established specific conditions for the reopening of the strait [1], [4].

The Strait of Hormuz serves as the primary maritime chokepoint between the Persian Gulf and the Gulf of Oman [4]. Before the current conflict, about 20% of the world's oil and liquefied natural gas passed through this channel [2].

While Tehran and Oman are reportedly nearing a new agreement regarding shipping lanes [4], the Iranian government has tempered expectations for a rapid resolution [1]. This tension has kept global oil traders monitoring the market closely for further signals from the region [1].

Industry observers said the current price volatility is linked to the strategic importance of the waterway. Because one-fifth of global oil and LNG depends on this passage [2], any ambiguity regarding its status creates immediate pressure on futures markets.

Iran's decision to set conditions rather than announce an immediate opening has shifted the market sentiment from optimism to caution [1], [4]. Traders are now weighing the likelihood of a diplomatic breakthrough against the risk of continued disruption in the Persian Gulf.

The sensitivity of oil prices to the Strait of Hormuz underscores the fragility of global energy security. Because the waterway handles roughly one-fifth of the world's oil and LNG, Iran possesses significant leverage over global markets. The shift toward conditional reopening suggests that the maritime passage is being used as a diplomatic tool, meaning prices will likely remain volatile until a formal shipping agreement with Oman is finalized.
