Citi Warns of Diesel Pullback Risk as Speculative Bets Near Historical Ceiling

Speculative positioning in diesel futures has become so overstretched that it is nearing a historical ceiling, increasing the risk of a sharp price correction, according to a new warning from Citi Research.

This analysis comes as Brent crude prices have rallied in August, climbing from below $80 to approximately $89 per barrel, driven by persistent geopolitical risks.

Positioning Reaches Critical Level

Analysts at Citi noted that net long positions held by managed money in ICE diesel futures are once again approaching multi-year highs. This bullish positioning has been the primary driver supporting strong refining margins and diesel crack spreads.

According to the bank, data as of last week showed these net long positions were nearing the 100,000-contract range. Citi stated that this level has historically acted as a cap, with positioning often experiencing a rapid and significant reversal after reaching it. "Such overstretched positioning has historically tended to reverse quickly," the report noted.

Geopolitical Risks Underpin Prices

The strength in the energy market is underpinned by several ongoing conflicts. Citi, citing data from Kpler, reported that vessel traffic through the Strait of Hormuz fell sharply over the weekend. Other key factors include:

• Escalating Houthi attacks in the Red Sea and against Saudi Arabia.
• Continued Ukrainian drone strikes on Russian refining infrastructure, including the Bashneft-Novoil and Slavneft-YANOS refineries, as reported by CNBC.
• Stalled U.S.-Iran talks and an alleged attack on a UAE-linked tanker in the Strait of Hormuz.

A Mirror Image of Early Summer

Citi contrasted the current bullish sentiment with the market dynamics of late June and early July. At that time, combined managed money net long positions in Brent and WTI crude were near multi-year lows, and market sentiment was overwhelmingly bearish, with some forecasts calling for oil to fall into the $60 or even $50 per barrel range.

However, an escalation in U.S.-Iran tensions quickly reversed that trend, driving both prices and speculative net long positions sharply higher. This previous reversal highlights how quickly market sentiment and positioning can shift in response to geopolitical developments.
