Gulf tensions and short covering drive energy higher amid renewed supply shock fears

Key Points:

• Energy dominates commodity performance as renewed Middle East tensions trigger the biggest one-day oil rally in more than three months, with Brent climbing above USD 86 while diesel and European gas lead gains
• The speed of the move reflects positioning as much as fundamentals, with heavily under-owned crude markets, aggressive short covering and thin summer liquidity amplifying the geopolitical risk premium
• Several factors may ultimately limit crude upside, including weakening Chinese demand, the transition beyond peak summer demand, and Saudi and UAE pipeline capacity that can bypass part of the Strait of Hormuz disruption.
• Gold is showing unexpected resilience, suggesting markets may increasingly be focusing on the broader economic consequences of a prolonged energy shock rather than simply its inflationary impact.

The Bloomberg Commodity Total Return Index has rallied sharply over the past week, driven overwhelmingly by the energy sector as renewed geopolitical tensions in the Middle East once again dominate commodity price action. Energy has gained almost 9% during this time, comfortably outperforming industrial metals, agriculture and soft commodities, while precious metals remain the only sector trading lower.

The latest escalation began last week after an Iranian tanker attack prompted renewed US strikes, before accelerating dramatically after President Trump reinstated the blockade on Iran and announced a 20% toll on all cargo transiting the Strait of Hormuz. Brent crude responded with its largest one-day gain in more than three months, surging more than 10%, before extending gains above USD 86 per barrel as traders continued to cover short positions and reassess the risk of renewed supply disruptions across the Persian Gulf.

Positioning turns a geopolitical shock into a price spike

While the geopolitical headlines provided the catalyst, the magnitude of the rally reflects how vulnerable the market had become to a bullish surprise. Over recent weeks, hedge funds had steadily reduced bullish crude exposure as expectations grew that improving Gulf security, weak Chinese demand and rising OPEC+ production would keep prices contained. Instead, many investors found themselves wrong-footed as supply risks returned, forcing aggressive short covering into a market already characterised by thin summer holiday liquidity. With fewer willing sellers, relatively modest buying quickly translated into outsized price moves. The rally therefore reflects both a renewed geopolitical risk premium and a positioning squeeze, with technical factors amplifying what remains an uncertain fundamental outlook.

Why USD 100 Brent is not a foregone conclusion

Despite the latest surge, several important mitigating factors continue to argue against an extended move towards USD 100 Brent.

Firstly, the market has now rolled into the September Brent contract, meaning prices increasingly reflect demand beyond the peak northern hemisphere summer driving season. Seasonal refinery demand typically begins to soften from late August, reducing some of the immediate pressure on crude markets.

Secondly, China continues to provide an important offset to supply concerns. Crude imports fell to their lowest level in almost a decade last month as refinery runs weakened amid sluggish domestic demand and continued economic uncertainty. Should prices continue rising, Beijing is once again likely to respond cautiously, rebuilding inventories only gradually in order to avoid becoming the marginal buyer that drives prices materially higher. China's subdued demand has repeatedly acted as an important stabiliser during previous periods of geopolitical disruption.

Finally, while the Strait of Hormuz remains one of the world's most critical energy chokepoints, the market also recognises that Saudi Arabia and the United Arab Emirates retain significant pipeline infrastructure capable of bypassing parts of the strait. While these routes cannot replace all Gulf exports—particularly those from Iraq, Kuwait, Qatar and Iran—they nevertheless reduce the probability of a complete disruption to regional crude supplies.

Refined fuels remain the real inflation story

If crude oil tells only part of the story, refined products continue to paint a much tighter picture. Diesel remains the standout performer across global commodity markets, with both European gas oil and US ULSD futures rising around 18% over the past week. At the same time, European natural gas has climbed almost 14%, lifting Dutch TTF futures above EUR 53/MWh, their highest level in three months.

Unlike crude oil, refined products face far fewer mitigation options. Several Middle Eastern refineries remain affected by the ongoing conflict while Russia's diesel export restrictions continue to constrain global availability. Refining capacity globally also remains relatively limited, preventing crude supply increases from quickly translating into additional diesel and gasoline production.

As a result, refining margins have expanded sharply, leaving end users increasingly exposed to fuel costs more commonly associated with Brent trading well above current levels. For consumers and industry alike, it is refined fuel prices—not crude itself—that ultimately determine the economic impact of an energy shock.

This distinction matters because elevated diesel and gasoline prices feed directly into freight costs, manufacturing, agriculture and inflation, potentially creating a more persistent drag on economic activity than crude prices alone would suggest.

Is gold beginning to look beyond inflation?

Recently, rising oil prices created headwinds for precious metals by lifting inflation expectations, supporting bond yields and strengthening the dollar. That dynamic was also evident in the past few days as US Treasury yields moved higher, with the two-year yield climbing to its highest level in more than a year at 4.29% as markets priced a greater likelihood of further Federal Reserve tightening. Fed funds swaps now imply roughly a 50% probability of a July rate hike, with a full 25-basis-point increase priced by September following Governor Waller's comments that additional tightening may be needed to bring core inflation under control. Initially, gold followed this familiar pattern, falling below the psychologically important USD 4,000 level.

However, as Brent extended its advance towards USD 86 and beyond, bullion stopped falling. Instead, buyers re-emerged, lifting gold back above USD 4,000 despite oil, yields and inflation concerns remaining elevated. It remains too early to conclude that the recent inverse relationship between oil and gold has broken down. Nevertheless, the latest price action may indicate that markets are beginning to look beyond the inflationary consequences of higher energy prices and instead focus on the broader economic risks associated with a prolonged energy shock.

Persistently elevated diesel, gasoline and natural gas prices have the potential to slow economic growth, squeeze corporate margins and weaken consumer spending. Should those concerns begin to outweigh the prospect of tighter monetary policy, gold's traditional safe-haven characteristics may once again come to dominate price action.

Three questions that will determine what comes next

For now, crude oil remains the central driver of cross-asset pricing. Whether this latest rally evolves into another sustained energy bull market or proves to be another positioning-driven spike will depend less on military headlines than on three key questions: whether physical exports through the Gulf remain disrupted, whether China continues to suppress global demand through weak imports, and whether exceptionally tight refined fuel markets begin to spill over into broader economic activity.
