Opening the taps on diesel reserves is a risky gamble for Europe

In an attempt to mitigate a diesel crisis exacerbated by the US-Iran war, the Group of Seven (G7) nations have agreed to release emergency petroleum stocks. US President Donald Trump, facing re-election in a month, may be maneuvering to secure a favorable outcome. The G7 will distribute 100 million barrels over four months, with a larger share allocated to diesel.

This move comes after the Gulf shipping scheme, protected by US naval vessels and aircraft, successfully restored crude oil flows to near prewar levels. However, the situation remains precarious as Europe and Japan possess substantial petroleum product reserves, particularly diesel and petrol, while the US's strategic petroleum reserve primarily contains crude oil.

The US has already extracted a significant portion of its strategic reserves, leaving limited capacity for further withdrawals. Despite the proposed release, it is unlikely that Europe will fully rely on these reserves, as the crisis is not solely centered around diesel availability. Moreover, the ownership of European petroleum stocks differs from the US model, as they are held by private oil companies rather than government entities.

This arrangement may limit the immediate impact of the release on Europe's diesel supply. While the G7's decision aims to alleviate the crisis, it remains uncertain whether the participating nations will fully utilize their reserves, especially as the US presidential election approaches. If the US backs down from imposing a diesel export ban following the elections, European nations may avoid the worst consequences of the crisis.

However, if the conflict escalates further, and Iran retaliates against its adversaries, the situation could deteriorate rapidly, potentially leading to a repeat of refinery damage witnessed in Israel and several Gulf states. In this volatile scenario, Europe must strike a delicate balance between appearing to comply with Trump's demands and preserving strategic reserves for future contingencies.
