CPC disruption is tightening the Med and lifting Black Sea freight and insurance costs, pushing refiners towards Saudi and Atlantic barrels. That should support WAF differentials and prompt DFL.
Key Takeaways
Repeated attacks around the CPC terminal have pushed Black Sea transit risk directly into physical pricing. Loadings remain suspended and August bids have gone unanswered, keeping CPC Blend differentials firm as sellers hold back. With no confirmed damage to the SPMs, the market is pricing uncertainty over resumptions, vessel availability and insurance rather than a lasting supply loss. If the outage extends beyond the week, Kazakhstan will likely divert what it can through Russian pipelines, BTC and Georgian terminals while bringing field maintenance forward, potentially removing up to 1mbd of Kazakh crude from the Med and leaving refiners with a larger replacement problem.
That brings WAF and North Sea grades firmly into play. Dalia is one option, with its low sulphur and strong middle-distillate yield fitting the current margin environment, although its higher TAN raises corrosion risk and processing costs. Nigerian light sweets also offer useful blending flexibility. Our arb tool shows light sweet grades generating FCC margins above $30/bbl, leaving refiners enough room to absorb higher crude costs and maintain runs. These barrels are already being tested, with Sarroch receiving a Dalia cargo last week and another expected next week after a one-year hiatus.

Saudi barrels should take some of the pressure off. During last year’s Israel-Iran conflict, exports from Sidi Kerir picked up sharply as Europe looked for alternative supply. The latest Aramco OSP cuts have now improved Arab Light’s competitiveness for August loaders, with the grade landing only around $0.50/bbl above Dalia, compared with roughly $7/bbl two weeks ago. Once Dalia’s higher TAN and processing penalty are included, the Saudi barrel looks better value. With Bab el-Mandeb risk also rising, Med refiners should pull more Arab Light alongside WAF and North Sea grades as CPC supply tightens.

That stronger pull should give Aramco room to hold or raise European OSPs, while the extra competition for WAF and North Sea barrels remains supportive of prompt DFL. Higher Black Sea insurance and freight should also make CPC less competitive on a delivered basis, opening the door for more Angolan WAF into the Med. If refiners like the fit, some of that rerouting could remain even after CPC loadings normalise.
