Oil Slides a Fifth Day as US-Iran Deal Nears Friday Signing

Oil keeps falling, and the reason is a signature that has not happened yet. Crude slid for a fifth straight session on Wednesday, with Brent near 79 dollars and WTI around 75, as traders price in the return of Iranian barrels ahead of a US-Iran deal set to be signed Friday in Switzerland. The market is moving on the deal before the ink is dry.

This is the tail end of a long unwind. Oil spiked earlier in the year when the US-Iran conflict put the Strait of Hormuz at risk, the chokepoint a big slice of the world's crude passes through. As the fighting cooled and the talks advanced, that war premium drained out. Brent is now down close to 40 percent from its conflict peak. Different phase of the same story.

The interim agreement, due to be signed in Switzerland on Friday, hands Tehran broad economic incentives, including the immediate resumption of its oil exports. It also eases restrictions on shipping through the Strait of Hormuz. More than 100 oil-laden ships have been stuck in the Gulf, and their release would push a wave of supply back onto a market that no longer fears a shortage. Tanker operators are already repositioning toward the region.

Brent traded just under 79 dollars, its lowest since early March, WTI around 75 to 76. Five sessions down in a row. The move is orderly. Each day without a supply scare takes a little more risk premium out. Energy stocks feel it. The broader read is cleaner: cheaper oil cools inflation pressure, which matters on a day the Fed is also deciding rates.

The near-term path runs through Friday. If the deal gets signed and the ships sail, the extra supply caps any rebound and could push prices lower still. The risk on the other side is durability, since shipping firms remain cautious about how long the agreement holds. One flare-up in the Gulf and the war premium snaps back fast. For now the market is betting on calm.

So oil is doing the math early. A deal on Friday, Iranian crude back on the market, and a chokepoint reopening add up to more supply and less fear. Brent at a three-month low says traders already believe it. The signing is the formality. The price already moved.
