Oil Prices Head for Worst Month Since 2020 on Hormuz Deal Hopes

Yahoo Finance reported Friday that oil prices are tracking toward their steepest monthly decline since 2020, with the Strait of Hormuz at the center of shifting market sentiment. Brent crude is on course to close May sharply lower as traders price in a growing probability that Washington and Tehran could be approaching a diplomatic agreement.

Hormuz Fears Fade, Prices Follow

The Strait of Hormuz sits at the mouth of the Persian Gulf. It handles roughly 20% of global oil flows. Any credible signal that the waterway could remain open — or reopen following threats of closure — carries immediate weight in energy markets. Recent signs of progress in US-Iran negotiations have eased the geopolitical risk premium that had been supporting crude prices for much of the month.

Brent crude, the international benchmark, is heading for its worst monthly performance in roughly six years. That puts it on track to erase a significant portion of gains accumulated during the earlier phase of Hormuz tension this year.

Background: Why Hormuz Matters So Much

The Strait of Hormuz has historically been one of the most strategically sensitive chokepoints on earth. Iran has repeatedly threatened to close the passage during periods of heightened tension with Western powers. Even unverified threats tend to push crude higher. Actual disruption would remove millions of barrels of daily supply from global markets almost instantly. That sensitivity explains why any movement toward a US-Iran nuclear deal carries such outsized influence over oil pricing.

The 2020 precedent is also significant. Brent crude suffered historic losses that year as pandemic demand destruction combined with a Saudi-Russia price war. Matching that monthly decline now — in the absence of a comparable demand shock — underscores how heavily geopolitics have driven prices in May 2026.

What Traders Are Watching Next

Oil market participants are closely monitoring the pace and tone of US-Iran diplomatic communications. A formal agreement would likely trigger a further leg down in crude as supply risk evaporates. Conversely, any breakdown in talks could rapidly reverse the month’s losses. OPEC+ production decisions remain a secondary factor. The Hormuz narrative is, for now, the dominant force shaping the energy complex going into June.
