The Arb View: Atlantic Basin barrels come into play

Red Sea tensions have shifted oil trading dynamics, particularly for the Atlantic Basin. Disruptions have redirected Dubai and reopened west-to-east arbitrage opportunities, while a halt in the CPC removed about 800 kbd of crude from the Mediterranean. Despite this, a potential downward revision in prompt Dubai Light (DFL) should remain supported, with Europe possibly benefiting from Saudi barrels rerouted through the Sinai Petroleum Oil Pipeline (SUMED).

Asian markets now offer more favorable economics for Midland, with traders anticipating a response from physical flows. Key observations include:

1. Red Sea closure has decreased tanker crossings to eight per day, down from 30, with Bab el-Mandeb liquids-tanker traffic falling significantly.

2. The widening of Brent-Dubai and Murban cash differentials to $7/bbl and $15/bbl, respectively, has reopened the west-to-east arbitrage on paper.

3. Midland is now trading at around $9/bbl below Murban for September loaders, a level seen in March.

4. Longer voyages, STS operations, and restricted Red Sea access are increasing costs, potentially deterring Asian refiners.

5. Reduced Latin American crude exports and increased Panaman Canal transits could fill the supply gap.

6. CPC tightening is prompting Saudi barrels to divert west through SUMED, adding supply to the Mediterranean as halted CPC loadings remove roughly 800 kbd of sour crude.

7. Sour grades remain firm while CPC barrels are trapped, with rising Johan Sverdrup differentials making Atlantic alternatives more competitive.
