Brent slips 1.6% to $103 as Russian diesel talk meets continuing Gulf strikes

Brent futures slipped 1.6% to $103.01 a barrel in thin Monday trade as Trump's Russia-Ukraine energy ceasefire met continuing Gulf strikes on shipping and airports. The drop is roughly $1.70 on a holiday-thinned session, a narrow basis for any view on supply.

Energy costs are seen lifting US CPI above core Forecast annual US CPI rate as rising energy costs feed through, Brent futures' gap to their recent top, and the US crude futures price.

What happened

  • Stock markets opened erratically on Monday, and oil slipped amid confusion over whether Russia would, or could, increase energy exports.
  • US crude futures lost 1.9% to $90.11 a barrel, a slightly larger percentage fall than Brent's.
  • South Korean stocks fell 2.2% and Taiwanese shares eased 0.5%, while MSCI's Asia-Pacific index excluding Japan dipped 0.3%.
  • Japanese markets were shut and the US was on a partial holiday, with major US banks due to open earnings season on Tuesday.
  • S&P 500 third-quarter earnings are expected to jump by more than 30%, according to LSEG IBES, with the bulk of that from tech.

Why it matters

  • constraint Senators in both parties called Trump's diesel plan potentially illegal, so a trader cannot yet count extra Russian diesel as supply.
  • exposure Markets price an 18% chance of a Fed hike this month and 85% by December, a 67-point climb, so energy-driven CPI surprises this week would test that path.
  • contradiction S&P 500 futures edged up 0.3% and Nasdaq futures 0.4% while the investment-grade credit default swap index sat at its highest since the Iran war began, so stocks and credit insurance are pricing different risks.

A 1.6% fall to $103.01 implies a prior price near $104.7, so the session took out roughly $1.70 [17], and Brent had started it higher [5]. It is still $6.96, or 6.3%, below the recent top of $109.97 [18]. A market that believed Russia was about to ship meaningfully more diesel would, in our view, have sold harder than that (or rather, would have sold harder on a day with normal volume, and Monday had thin trade [7]).

Diesel is the interesting puzzle. "Oil prices remain higher than we had assumed as shipping costs have soared and product prices are even higher," said Bruce Kasman, head of global economics at JPMorgan [10]. Diesel is a refined product, so Trump's proposal for Russia to export more of it [4] aims at the category Kasman calls "even higher". The inflation forecasts show the stakes: US CPI is expected to rise 0.6% on the month to 3.7% annual, with core at 0.2% and 2.5% [11], a 1.2-point gap between headline and core [19].

Credit is the other price in play. My Bui, an economist at AMP, said tech had supplied the S&P 500's entire gain since mid-September, and that investors wanted higher yields on the debt being raised to pay for AI [13]. "Overall, wider spreads suggest investors are questioning whether AI revenues can keep pace with rising borrowing costs," Bui said [14].

This can still go several ways. If the ceasefire holds and Russian diesel moves, Brent falls through $103 and stays there; if the Gulf strikes on shipping widen [2], it revisits $109.97 [5]; if neither is verified, it moves between the two. We think the third is likeliest this week, because the report does not include ceasefire terms or a volume for the extra diesel, and Brent is trading the announcements until one of them is verified. We would be wrong if Brent is still below $103 once Japanese markets are open and US trading is back at full volume.

What to watch

  • Whether Brent stays below $103 once Japanese markets are open and US trading returns to full volume.
  • US consumer and producer price data and retail sales this week, which set the test for December hike odds now at 85%.
  • Any published terms of the Ukraine-Russia energy ceasefire, or a Senate move on the diesel export proposal.
