Is Brent setting a trap below $90 as Russia quietly tightens fuel supply?

Oil prices edged lower on Friday and were heading for their first weekly decline in three weeks as hopes of improved shipping through the Strait of Hormuz outweighed fresh supply risks from Russia.

Brent crude fell about 0.3% to $89.45 a barrel in early trade, while US West Texas Intermediate slipped 0.3% to $83.31.

Brent is down roughly 5.3% this week and WTI about 4.3%, reversing part of their recent rally.

The market is now caught between two geopolitical forces: Middle East diplomacy is removing some risk premium, while Ukrainian attacks on Russian energy infrastructure are tightening the refined-fuel outlook.

Hormuz hopes take some heat out of Brent

Iran and Oman have moved closer to a framework for managing shipping through the Strait of Hormuz, including a temporary corridor and negotiations over the waterway’s future administration.

Iranian officials have also discussed sharing revenues associated with services in the strait. But important details remain unresolved, including when commercial vessels can safely use the new route.

Tehran has stressed that the agreement does not amount to a full reopening.

That distinction matters for Brent, which is particularly sensitive to seaborne Middle East supply.

The prospect of increased traffic pushed crude sharply lower earlier this week. Yet prices recovered from those lows as Washington showed little appetite for restarting direct negotiations with Tehran, reducing confidence that a comprehensive Hormuz settlement is close.

ANZ Research analysts see fading hopes for an immediate reopening as supporting crude after the earlier selloff. In their view, actual progress on restoring traffic remains more important than announcements around a potential framework.

Russia adds a different supply problem

Attention is meanwhile shifting towards Russia, where repeated Ukrainian attacks on refineries and export infrastructure are disrupting fuel availability.

Russia has imported more than 1 million barrels of gasoline by sea since late July to address domestic shortages, according to vessel-tracking data from S&P Global Commodities at Sea and Kpler. Additional supplies have come from Belarus and Kazakhstan.

Moscow is also preparing to extend restrictions on diesel exports through September after Ukrainian attacks left several refineries idle and contributed to recurring regional fuel shortages.

That is important because refinery damage affects gasoline, diesel and jet-fuel availability even if Russia can continue pumping crude. Product markets were already tight after months of disruption across the Middle East.

MUFG strategists have suggested that recent strength in crude could mark the beginning of another energy-price rebound.

However, their assessment hinges heavily on how much traffic is genuinely moving through Hormuz rather than what diplomatic statements imply.

Weekly losses hide a fragile balance

Oil’s weekly decline therefore does not signal that geopolitical risk has disappeared.

Brent has retreated from above $94 earlier this week, but a concrete increase in Hormuz tanker traffic is still needed to justify removing more of the Middle East premium.

At the same time, further damage to Russia’s refining system could tighten global fuel supplies.

The next move may depend on which development becomes more tangible first. A functioning Hormuz corridor would strengthen the bearish case.

A breakdown in diplomacy, another shipping incident or deeper Russian refinery outages could quickly put $90 Brent back in play.
