G7 Oil Release Pressures Diesel Margins Amid Persian Gulf Tensions

The G7's decision to release 100 million barrels of crude oil and diesel has put downward pressure on refinery margins for middle distillates, which had reached record highs last month. The stock releases, set to begin over the next four months, along with reduced concerns about a U.S. ban on diesel exports, have caused the ICE gasoil crack to drop to around $70 per barrel. This is down from a peak of $85 per barrel just last week, according to Warren Patterson, Head of Commodities Strategy at ING.

The diesel crack spread, a key indicator of refinery profitability when converting crude oil into diesel, remains historically high despite the recent decline. Analysts, including those from ING, note that the G7's action provides only temporary relief and does not address the underlying market tightness. Patterson emphasized that the long-term solution requires the resumption of refined product flows from the Persian Gulf.

Tensions in the Middle East continue to escalate, with recent attacks on commercial vessels near the Strait of Hormuz. UK Maritime Trade Operations (UKMTO) has reported seven strikes on vessels in the area since September 28. Additionally, a U.S. official recently told the Wall Street Journal that Iran's ability to target ships has improved, making transit through the Strait of Hormuz riskier.

The ongoing geopolitical risks and supply constraints highlight the challenges in achieving a sustained balance in the middle distillate markets.
