Oil Slides as US-Iran Talks Flicker But the Strait Stays Shut

In early Asian trade on Tuesday, Brent oil fell to between $97.50 and $98.04. Different times of the day showed that WTI fell between $91.34 and $96.83. There is a real difference between those numbers that shows this market is moving quickly and in both ways, sometimes in the same session.

The story on Monday was very different. After the U.S. forces started blocking Iranian ports, Brent went up more than 4% and WTI went up almost 3%. 

Then Tuesday came around, JD Vance did an interview on Fox News, and traders who were waiting for things to get worse started pulling back. No, not because the danger is over. It's not. But because the "total breakdown" line moved a little toward "tenuous stalemate," and that's enough to cause a selloff in this hot oil market.

The availability problem that was there before hasn't changed. ANZ experts think that about 10 million barrels of oil per day have been taken off the world's crude markets. Ten million barrels per day is a number that you should think about for a moment.

About 103 million bpd are used around the world. Losing almost 10% of that, even if it's only partly or temporarily, is not a problem that goes away with the news cycle.

What Vance Actually Said — and What the Market Heard

Reports that ceasefire talks in Pakistan over the weekend had totally broken down were shot down by U.S. Vice President JD Vance on Monday evening. During the talks in Islamabad, he talked about having what he called "good conversations" with Iran on Fox News. He said that Iran should be the one to start the present standoff.

"The country is no longer under attack." Vance said, "What we expect the Iranians to give up is a full reopening of the Strait of Hormuz." He also said that the U.S. wants Iran to stop enriching uranium, saying, "There really is a grand deal to be had here, but it's up to the Iranians to take the next step."

The markets saw this as a sign that things would calm down, or at least not get worse. The difference is important. Vance wasn't making a deal public. He was saying that Washington is still open to one, which is a much lower bar. But since the price of oil had been above $118 at Brent's most recent high point, after a 63%+ monthly rise in March, even a small drop in tail-risk is seen as bearish by traders who have big long holdings.

However, Tim Waterer, chief market expert at KCM Trade, put it well: Trump had "some steam taken out of the oil price again dangling the carrot of a possible deal." Resolution is not that. That's what expectation management does, which isn't quite negotiation yet.

The Blockade Is Real — and So Are Its Limits

On Monday, the U.S. military announced that its blockade of Iranian ports would go through the Strait of Hormuz and into the Gulf of Oman and the Arabian Sea. MarineTraffic.com's ship tracking showed that most ships were staying away from the crossing as of Tuesday morning. However, a few oil tankers and cargo ships seemed to have gone through over the previous two days..

Trump said that 34 ships had gone through Hormuz before the ban started. He said that this was the most ships that had been through since the Iran war began in late February. It's not clear if that number shows real normalcy or just a last-ditch effort to get through before limits get tighter. The tracking data at the very least shows that throughput is still extremely limited.

In response to the blockade, Iran said it would target ports in countries that border the Gulf. This statement, which may have been meant to show resolve rather than an impending threat of action, made markets nervous because they were still worried about attacks on energy infrastructure across the area. Iran has hit energy production centers in several Middle Eastern countries since the fighting started. This has caused production to stop, which made the Hormuz problem worse.

Notably, important NATO partners like Britain and France refused to join the U.S. blockade and instead pushed for diplomatic ways to open the waterway again. This split makes the strategic picture more difficult and shows that Washington's alliance is smaller than it was earlier in the campaign.

The Supply Math That Doesn't Care About Headlines

When you take away the political noise, what you're left with is a supply shock of historic proportions. In a united statement, the International Monetary Fund, the World Bank, and the International Energy Agency called this the biggest shock to the global energy market ever. This doesn't make it sound like things will get better quickly.

Monday, Fatih Birol, the head of the IEA, said that the organization is ready to move, even though more strategic oil releases aren't needed right now. That is careful wording. There is no "we're releasing reserves"; there is only "we're watching." The difference shows that the IEA thinks the problems are serious, but haven't yet put consumer countries in a real emergency situation.

According to ANZ's calculations, a sustained U.S. blockade could remove 3 to 4 million bpd from the market, in addition to the 10 million already off. That amount keeps Brent above $100 regardless of diplomatic statements since the physical market doesn't have enough oil to meet demand at lower prices.

In a client note, ANZ said, "The oil market no longer needs a worst-case escalation to justify higher prices." "Tight balances alone are sufficient to sustain the price of Brent near or above recent threshold levels."

That line needs to be read again. There is already a case for higher oil prices. It is not the bear case or the worst case. Other than that, it's all a matter of degree.

Who's Still Trying to Broker a Deal

Iran made it clear in public that it had no plans to continue talks. Trump made it clear that he didn't care if Iran came back to the table. Either way, it's likely that neither comment is policy but rather positioning.

Behind the public face, people who knew about the talks told reporters that Washington and Tehran were still talking. Pakistani Prime Minister Shehbaz Sharif stated that efforts are still being made to calm things down. The most recent round of talks took place in Islamabad, which is also the capital of Pakistan. Other Asian and Middle Eastern governments are also said to be working to set up new talks.

As of Tuesday morning, the two-week peace between the US and Iran looked like it would last. Since at least Sunday, there had been no new strikes. The biggest factor affecting oil prices right now is whether the ceasefire lasts or breaks down after Trump's dates. No amount of chart analysis or inventory data can tell us what will happen.

The U.S. Energy Secretary, Chris Wright, said that oil prices might reach their highest point in "the next few weeks" after shipping through Hormuz starts up again. This schedule is based on the idea that shipping will start up again, which is based on the idea that a deal will be made and Iran will take the action Vance said it would take. There are a lot of ideas there, and all of them must be true.

Two Paths From Here — One Is a Lot More Painful Than the Other

If talks about peace work, Hormuz will reopen, even if only partly, over the next few weeks. The supply gap of 10 million barrels per day starts to close. The extra risk that pushed Brent above $118 is slowly going away. As the physical market rebalances and consuming countries release strategic reserves to add to supply, WTI is likely to find a floor in the $80s. This is the best chance for the market, but Iran needs to change its stance first.

If the blockade hardens, Iran does not negotiate or the ceasefire fails. The 3–4 million bpd interruption risk from ANZ materialises. Hoarding by consumer nations is what the IMF, World Bank, and IEA cautioned against this week. Europe and Asia's Gulf crude-dependent supply chains make increasingly unpleasant contingency decisions. Brent doesn't see a ceiling there. March saw a one-month surge from $70 to $118.

The pullback on Tuesday doesn't tell us which of those paths we're on. The market quickly thought the first path was more likely, as shown by this change. In a few weeks, that opinion might seem reasonable, or it might seem silly.

What's Worth Watching — Not What's Worth Reacting To

The Trump and Vance statements will keep generating volatility. That's not where the real signal is.

Tanker tracking data from Hormuz and the Gulf of Oman is more accurate than diplomatic readouts for ship movement. If announced, IEA coordinated reserve releases would indicate the agency believes the disruption is greater than it claims. Iran's response to the blockade in the next days—whether it attacks Gulf oil infrastructure or retreats—will determine whether the ceasefire lasts.

For longer-term traders, Brent's forward curve shape indicates whether the market expects a near-term interruption or a structural supply issue. Deep backwardation—front months trading much above deferred months—indicates a tight actual market, not merely in expectation. That amount matters more than single-session price moves.

Oil is down Tuesday. Ten million barrels a day are still missing. Those two facts aren't in conflict — they're just measuring different things.
