Goldman Sachs Raises Global Diesel Refining Margin Forecast on Tight Supplies

Diesel Spreads Surge on Supply Crunch

Goldman Sachs Group Inc. has significantly increased its 2024 global diesel refining margin forecast, citing a confluence of persistent tight supply conditions across key markets. The investment bank now projects average diesel crack spreads to reach $28 per barrel for the year, a material uplift from its previous estimate of $24 per barrel. This revision underscores an expectation of sustained strength in middle distillate prices, driven by structural supply constraints and resilient demand.

The announcement immediately resonated across energy markets, with prompt-month NYMEX Ultra-Low Sulfur Diesel (ULSD) futures responding with a 2.3% surge to $2.75 per gallon. European ICE Gasoil futures for March delivery also saw robust gains, climbing 1.8% to $850 per metric ton, signaling broad-based market recognition of the tightening supply narrative. This upward price action reflects a renewed bullish sentiment towards refined products, particularly diesel, which is critical for industrial, agricultural, and transportation sectors.

Market Impact

The upgraded forecast by Goldman Sachs has translated into tangible shifts across the energy complex. The Brent crude oil crack spread for gasoil, a key measure of refiner profitability, widened by $1.50 per barrel to $32.50 per barrel on Tuesday, reaching its highest level in three weeks. This expansion signals that refiners are capturing a larger premium from processing crude into diesel, incentivizing higher throughputs where capacity allows.

Globally, distillate inventories remain notably constrained. US distillate stocks, which include diesel and heating oil, were reported at 122 million barrels as of the latest EIA data, approximately 12% below the five-year seasonal average. In Europe, the ARA (Amsterdam-Rotterdam-Antwerp) region, a crucial hub for refined products, saw gasoil inventories fall by 5% last week to 2.1 million metric tons, marking the lowest level since October 2023. This persistent deficit contributes significantly to the elevated margin environment.

The positive outlook for refining margins has also bolstered the equity performance of major independent refiners. Shares of Phillips 66 ($PSX) advanced by 1.9% to $158.20, while Valero Energy Corp. ($VLO) climbed 2.1% to $172.50. Marathon Petroleum Corp. ($MPC) saw a 1.7% increase to $201.30. These gains reflect investor confidence in the sector's ability to generate strong cash flows amid favorable pricing conditions, especially as refining margins account for a substantial portion of their earnings.

What Analysts Are Saying

Goldman Sachs analysts, led by Roger Hirst, attributed the margin upgrade primarily to "structurally lower global diesel inventories and ongoing geopolitical disruptions." They highlighted that Chinese refined product export quotas for 2024 remain below pre-pandemic levels, limiting a major source of global supply. Furthermore, the analysts noted that European demand continues to outstrip regional refining capacity, necessitating persistent imports, which are now more expensive due to Red Sea shipping diversions.

"The global diesel market is facing a perfect storm of factors, including persistent refinery maintenance schedules, lower-than-expected Chinese export volumes, and robust industrial demand," stated analysts at JPMorgan Chase & Co. in a client note. They project that European gasoil imports will need to remain elevated throughout the first half of 2024, maintaining upward pressure on pricing.

However, some analysts offer a more cautious perspective. Morgan Stanley equity research highlighted potential headwinds, including the possibility of demand destruction if prices rise too sharply, or the eventual ramp-up of new refinery capacity in regions like the Middle East and Asia later in 2024. "While the near-term outlook is undoubtedly strong, investors should monitor the elasticity of demand and the timing of new supply coming online, which could temper margins in the latter half of the year," a Morgan Stanley report suggested.

What to Watch

Investors should closely monitor several key indicators and events that could influence global diesel refining margins. Firstly, weekly inventory reports, particularly for US distillate stocks from the EIA and ARA gasoil levels from Insights Global, will provide crucial insights into supply-demand balances. A sustained build in these inventories could signal easing tightness and potentially pressure margins.

Secondly, the utilization rates of global refineries, especially in Europe and the US Gulf Coast, will be critical. Any unexpected outages or prolonged maintenance periods could further tighten supplies and support margins. Conversely, a significant increase in utilization, particularly from units returning from maintenance, could add supply to the market.

Thirdly, China's refined product export policies and actual export volumes for diesel will be a significant determinant. Any deviation from current subdued export levels could materially alter global supply dynamics. Geopolitical developments, particularly those affecting shipping routes like the Red Sea, also remain a key risk factor, as disruptions can significantly increase freight costs and lead times for refined products.

Finally, upcoming earnings reports from major refiners in the first and second quarters of 2024 will offer direct guidance on company-specific outlooks and capital allocation plans amidst the strong margin environment. Investors should also track global economic growth forecasts, as a slowdown could dampen industrial and transportation demand for diesel, potentially reversing the current bullish trend.
