Oil Prices Are Up From a Six-Week Low, Brent Crude Around $93 as Iran-US Negotiations Continue Unresolved

Oil markets are sending a clear message about the state of Iran-US negotiations: close enough to move prices, far enough from resolution to keep them elevated. Brent crude climbed back toward $93 a barrel at the start of June after touching a six-week low in the final days of May a recovery that captures in a single price chart the back-and-forth that has defined three months of fragile ceasefire, stalled diplomacy, and intermittent military strikes.

The volatility is not noise. It is a real-time referendum on whether the world’s most important oil chokepoint is about to reopen and the market’s answer, as of this week, is: not yet, and not certain.

How We Got to a Six-Week Low

To understand the current recovery, it helps to understand what caused the dip. Brent crude suffered its worst monthly performance since the Covid-19 pandemic in May alone, falling nearly 19 percent from its 2026 peak of around $108 a barrel. The driver was a specific kind of optimism: as reports of a tentative 60-day memorandum of understanding between Washington and Tehran began circulating in mid-to-late May, traders priced in a deal that would reopen the Strait of Hormuz and restore approximately one-fifth of global oil and LNG flows to the market.

CNBC reported that oil dropped roughly 20 percent from its 2026 highs on “optimism over US-Iran ceasefire talks” — a move that reflected genuine expectations of supply restoration rather than any actual change in physical oil availability. The Strait of Hormuz remained closed. Iranian mines remained in the water. Not a single additional barrel had moved through the strait. But futures markets trade on expectations, and expectations had shifted sharply toward resolution.

Why Prices Bounced Back

The recovery from the six-week low has a specific trigger: fresh US military strikes on Iran around May 26, targeting missile launch sites and boats attempting to lay mines in southern Iran. CNBC reported that Brent crude jumped more than 3 percent on the day of those strikes, briefly touching $100 a barrel as Iran vowed to retaliate and investors reversed their ceasefire optimism.

The strikes exposed a market that had moved too far, too fast on deal expectations. When Trump left the Situation Room on May 29 without signing the MOU — after a two-hour meeting billed as a “final determination” — the signal to energy markets was unambiguous: the deal is not done, the strait is not open, and the supply disruption that has pushed crude prices to historic levels is not over.

Brent settled back toward the $92–$93 range, with WTI falling below $88 — reflecting a market that has recalibrated from peak optimism to something more cautious: a deal is likely, but its timing is uncertain, and its impact on actual physical supply will be gradual even after it is signed.

What Analysts Are Watching

Time reported that market analysts are projecting oil prices will remain in the $90 to $100 range “at least for the next couple of months” until there is greater clarity on any lasting peace agreement. UBS noted there is “little evidence” of any short-term improvement in vessel traffic or energy flows through the Hormuz region, despite the diplomatic momentum — a reminder that even a signed deal produces a time lag before physical supply normalizes.

That lag matters. The current MOU framework under US-Iran nuclear talks calls for Iran to clear mines from the strait within 30 days of signing. The Royal Navy and a Franco-British coalition are positioned to conduct mine-hunting operations once fighting stops, but their deployment cannot begin until a deal is formally in place. Even under the most optimistic timeline — deal signed this week, mine clearance completed within 30 days — Hormuz would not be fully operational until early July at the earliest.

Euronews reported that equity markets have risen on ceasefire optimism even as oil prices remain elevated — a divergence that reflects the distinction between what a deal means for corporate risk appetite broadly and what it means specifically for energy supply. Stocks are pricing in reduced geopolitical risk. Oil is pricing in continued supply constraint.

The Nuclear Variable Markets Cannot Price

The deepest uncertainty for energy markets is not whether the Hormuz reopens — it is whether the nuclear dimension of the US-Iran conflict remains unresolved in ways that make the current ceasefire inherently reversible. The proposed 60-day MOU defers rather than resolves Iran’s nuclear program question, launching negotiations during the window rather than extracting commitments upfront. Critics of the deal — including Republican hawks in Congress and analysts at institutions like the Heritage Foundation — have warned that a 60-day framework without nuclear resolution is simply a pause before a resumed confrontation.

If markets begin pricing that scenario — deal signed, Hormuz briefly reopened, negotiations collapse at the 60-day mark, conflict resumes — the current $93 level could prove to be a floor rather than a ceiling. The difference between a genuine peace agreement and a temporary truce is not semantic. For oil markets, it is the difference between a structural supply restoration and a temporary relief rally that reverses.

For now, Brent crude at $93 reflects exactly that ambiguity: better than $108, worse than $70, and anchored to a diplomatic process that the world’s most sophisticated trading desks cannot price with confidence — because the man who has to sign the deal left the room without signing it.
