Oil market: litmus test as stocks cushion geopolitical risks

Oil prices rose only modestly last week after further setbacks in negotiations between the United States and Iran, a markedly muted reaction compared to similar episodes in recent weeks.

According to Commerzbank AG, this measured response reflects the market’s increased ability to absorb disruptions through inventory draws, rerouting and demand adjustments.

Reduced price response to geopolitical risks

As hopes for a quick deal between the United States and Iran faded again, Brent and European natural gas saw only small gains last week.

However, the rise in oil prices was much more contained than during previous episodes of increased tensions.

Norman Liebke, FX and commodities analyst at Commerzbank AG, explained the dynamics:

“This can probably be explained by the fact that oil stocks are holding out longer than expected, even though stocks of some oil products have already fallen sharply.â€

He noted that the supply-demand deficit caused by the closure of the Strait of Hormuz was partially filled not only by inventory draws, but also by rerouting of exports, weaker demand in some regions and strategic releases of reserves.

However, oil prices rose more than 4% on Monday as geopolitical tensions rose following Israel’s latest attacks on Lebanon.

Markets remain uncertain and increasingly sensitive to geopolitical headlines.

Inventory cushion provides wiggle room

This inventory resilience gave the market more room to absorb shocks than many had anticipated.

While product stocks (notably gasoline and distillates) have decreased significantly, overall crude stocks have held up better, preventing a more pronounced surge in prices despite persistent geopolitical uncertainty.

However, the situation remains fluid. Any prolonged closure of the Strait of Hormuz or escalation of the conflict could further test these cushions in the coming months, especially as the Northern Hemisphere enters the peak summer demand season.

Key reports to guide market direction this week

This week will see several important data releases that could set the tone for oil markets for the remainder of 2026 and into 2027.

The US Energy Information Administration (EIA) is scheduled to release its monthly Short-Term Energy Outlook (STEO), which includes updated forecasts of global supply and demand.

Liebke a souligné l’importance des récentes données de production:

“Most recently, it reported a decline in daily global oil production of about 10.5 million barrels per day for March and April. This decline probably became more pronounced in May.â€

He added that this drop in production has, for now, limited relevance for the global market because oil cannot be shipped due to the blockade of the Strait of Hormuz.

The EIA will also address US LNG export capacity, a crucial topic given the constraints on Qatari LNG.

OPEC and Chinese data at the center of attention

On Thursday, OPEC will release its monthly report.

The cartel’s general secretary recently indicated that OPEC would maintain its relatively optimistic demand forecast, in contrast to more cautious projections from the IEA and EIA.

Chinese foreign trade data, expected next week, will also be closely scrutinized, Liebke stressed.

The current environment highlights the evolving capacity of the oil market to adapt to geopolitical shocks.

While inventories provided more support than expected, the combination of sustained seasonal demand, potential further production cuts and continued uncertainty around the Strait of Hormuz suggests that volatility is likely to persist.

Marché sensible 

Liebke and other analysts say the market remains sensitive to both positive diplomatic developments and any signs of renewed escalation.

Upcoming releases of EIA, OPEC and Chinese data will be crucial in determining whether current resilience continues or whether new price pressure emerges.

For now, the oil market appears to be in a cautious wait-and-see phase, balancing geopolitical risks with physical market realities that have proven more accommodating than many feared.

How this week’s reports impact expectations could determine whether this resilience continues or gives way to sharper price movements in the second half of 2026.
