From escalation to exit ramp: why oil's war premium is unwinding again

Searching for an exit ramp

The most important development has been talks between Iran and Oman, with the two sides discussing an interim framework aimed at resuming shipping through the Strait of Hormuz, including the establishment of a temporary joint navigational corridor and a project to clear mines from the waterway.

Importantly, such an arrangement would not require Washington and Tehran to immediately resolve the much larger disagreements surrounding sanctions, Iran's nuclear programme and regional security. Instead, it could provide a practical first step towards reducing the economic damage while broader negotiations continue.

Other developments also point towards de-escalation. The US has reportedly started returning diplomatic personnel to several Middle Eastern posts that were evacuated or downsized following the outbreak of war. The phased return includes missions in countries such as Saudi Arabia, Iraq, Israel and Lebanon, with other Gulf posts also expected to increase staffing. While hardly proof that the conflict is over, the move suggests Washington currently assesses the risk of renewed large-scale military escalation to have diminished.

Meanwhile, Washington's much-anticipated expansion of sanctions against Iran has so far proved less aggressive than feared. The Treasury sanctioned close to 60 Iran-linked entities, individuals and vessels and widened the range of activities potentially exposed to secondary sanctions. However, it stopped short of immediately imposing significant penalties on other countries continuing to trade with Iran and, importantly, did not target major Chinese financial institutions suspected of facilitating Iranian oil trade.

China, Iran's largest oil customer, has responded defiantly, arguing that its relationship with Tehran should not be disrupted and warning that it will take measures to protect its interests. The US may yet escalate its economic campaign, but for now its measured approach reduces the immediate risk of a sanctions confrontation with Beijing that could further disrupt global energy flows.

After six months of conflict, the incentives for finding an exit are becoming increasingly clear. Iran desperately needs economic relief and improved access to its oil export markets. Washington, meanwhile, needs energy normalisation after months of elevated fuel prices, SPR releases and disruptions across the Gulf.

Crude is pricing diplomacy before physical recovery

The speed of this week's sell-off is particularly notable because there has been little evidence yet of a meaningful recovery in physical flows. Ship traffic through the Strait of Hormuz remains severely depressed. Preliminary Kpler data cited by Reuters showed just five commodity vessels crossing on August 25, compared with a ten-day average of around 15. Before the conflict, the Strait handled roughly one-fifth of globally traded oil and LNG.

In other words, crude prices are falling not because large volumes of disrupted oil have suddenly returned to the market, but because traders are assigning a greater probability to their return in the coming weeks.

The market has moved from pricing a high probability of prolonged disruption and renewed escalation towards pricing partial reopening, negotiated shipping arrangements and a lower risk of renewed military confrontation.

This also leaves the market vulnerable in both directions. A credible agreement that rapidly restores Hormuz traffic could remove another layer of geopolitical premium. Conversely, a breakdown in negotiations could force traders to rebuild risk premium almost as quickly as it has disappeared.

Product stress eases but remains extreme

The same improvement in sentiment is visible in refined products, although here the physical tightness remains much clearer. The WTI-ULSD spread has retreated to around USD 88 per barrel after recently trading above USD 100, while the Brent-gasoil spread has dropped back below USD 70 from above USD 80 last week.

Those are substantial declines, but they should be viewed in context. Both remain at exceptionally elevated levels compared with normal conditions. This time last year, the WTI-ULSD spread traded just above USD 30, while the Brent-gasoil spread traded around USD 22 per barrel, highlighting that the refining system continues to face severe constraints even as the panic premium begins to ease.

Middle Eastern refinery outages remain an important factor, while developments in Russia are adding another layer of pressure, particularly across middle distillates. Repeated Ukrainian attacks have disrupted Russian refineries and export infrastructure, potentially restricting diesel exports through September as Moscow attempts to protect domestic supplies amid refinery outages.

Based on these observations, we can conclude that crude is increasingly trading diplomacy while diesel and gasoil are still trading scarcity.

Peace dividend or premature optimism?

The sharp correction in crude reflects signs of an improving diplomatic backdrop, and after months of confrontation both sides increasingly have economic reasons to seek a way out.

The immediate downside risk for oil is clear: successful negotiations followed by a sustained reopening of Hormuz could release trapped Gulf barrels, ease shipping costs and further reduce the geopolitical premium. Back in June, when the Strait opened for a few weeks, Brent crude slumped all the way to USD 70 per barrel.

The opposite risk is equally important. The market may already be pricing the first stages of a peace dividend before any meaningful peace dividend has actually arrived. Looking again at the most recent developments, the failure to secure a deal following the June reopening drove renewed hostility and a subsequent USD 30 rebound in Brent.

Based on these recent developments, the only thing traders seem to be guaranteed is continued price volatility. It remains to be seen not whether tensions have eased — they clearly have — but how much de-escalation is already reflected in the price.

For now, the market appears willing to believe that Washington and Tehran have finally found sufficient reason to search for an exit ramp. The next test will be whether diplomacy can turn that expectation into ships actually moving through Hormuz again.
