Crude oil prices pulled back Friday but stayed on course for a second consecutive weekly gain. The Strait of Hormuz, a narrow passage connecting the Persian Gulf to the open ocean through which Gulf crude must travel to reach buyers abroad, sits at the center of that move. Hopes of a swift reopening of the channel had faded to near-zero by week's end, and the United States pledged to increase economic pressure on Iran.

The strait functions as a chokepoint. When access is disrupted or in serious doubt, traders pay more for oil that can still move, and that premium works its way into weekly prices. Two straight weekly gains in crude is the market saying it does not expect a fast resolution.

It helps to separate Friday's dip from the broader weekly trend. A single session can move in either direction as traders adjust positions going into the weekend. A second consecutive weekly increase means the market has looked at the Hormuz situation and settled on a view: the channel is not returning to normal soon.

Economic pressure, when Washington applies it to Iran, means measures that restrict Iran's ability to export oil and conduct financial transactions. The U.S. vow to increase those measures matters for the timeline. The harder it presses, the longer any negotiated resolution of the strait dispute likely takes, and the longer that supply concern keeps prices from falling.

What was pledged versus what is currently in place is worth tracking. The U.S. made a commitment, not an announcement of specific measures. And the strait, as of Friday, had not reopened.
