So, oil prices are still up there. It's Monday, and the market is trying to figure out if a barrel of West Texas Intermediate crude is going to settle above the big, round, psychologically important number of $100. The reason, as you've probably guessed, is that the war is still going on and the world's most important oil shipping lane is still effectively closed.

President Donald Trump added some fresh fuel to the fire over the weekend, threatening to strike Iran's crude export facilities on Kharg Island and demanding that seven countries join a coalition to police the Strait of Hormuz. He's also reportedly weighing a seizure of Kharg Island itself if tankers remain bottled up. For context, about 90% of Iran's oil exports ship from Kharg. Meanwhile, Iran's new supreme leader has vowed to keep the Strait closed if hostilities continue. It's a classic standoff, and the oil market is stuck in the middle.

This has led to a very direct question on the prediction market platform Kalshi: Does WTI close above $100? The bet resolves against the official Intercontinental Exchange (ICE) front-month WTI settlement price. If it's $99.99 or above at settlement, the "YES" bet wins. Below that, "NO" wins.

Early Monday, WTI futures were trading at $100.37 a barrel, up 1.68%, after earlier climbing as high as $102.40—their highest level since July 2022. So, it's above the line right now. But the Kalshi crowd isn't totally convinced it will stay there. The "YES" contract is trading at ¢66, which implies about a 59% probability that WTI settles above $100. Traders there are also pricing a 56% chance of a close above $101 and a 42% chance of pushing past $102. The message seems to be: $100 might hold, but a sustained breakout much higher is far from a sure thing. Kalshi stops taking new bets at 2:30 PM ET.

The Supply Squeeze

Here's the fundamental picture keeping prices elevated. Iran is blocking Gulf countries from exporting their oil while allowing tankers carrying its own crude to pass freely. This keeps the supply shock alive as long as the war does. Since the conflict began, WTI crude has surged nearly 50%, from around $67 a barrel on February 28 to above $100 by mid-March.

The Potential Relief Valve

But there are forces working in the other direction. Late Friday, Trump said he held off on striking Kharg's oil facilities and called for Iran to reopen the Strait of Hormuz. Any hint of real diplomatic progress could collapse prices fast. Furthermore, prices are currently holding firm despite a massive, coordinated intervention.

More than 30 countries are executing an emergency release of 400 million barrels from their strategic reserves—the largest such intervention in history. The U.S. alone is contributing 172 million barrels from its Strategic Petroleum Reserve. The Paris-based International Energy Agency (IEA), which is overseeing the effort, said on Sunday that Asian nations began releasing supplies immediately, with Americas and European stockpiles flowing by the end of March.

So, you've got a physical blockage of a key chokepoint and military threats against critical infrastructure pushing prices up. And you've got the world's governments literally tapping their emergency stockpiles in an unprecedented effort to push prices down. The market, for now, is siding with the geopolitics. The question for traders today is whether that's enough to definitively crack the $100 ceiling, or if it's just a temporary spike.
