Amsterdam

Amsterdam's own tank farms, the storage end of the ARA hub rather than its refining or pricing ends, are where a squeeze on inbound cargoes shows up first. Saudi Arabia's share of ARA imports had already dropped from 33-37% to 12% by mid-June as Hormuz closures cut Gulf loadings, with US and Brazilian cargoes filling the gap at $1.50-2.00 a barrel more in freight.

That replacement supply now travels the long way round via Suez rather than the short hauls Russian barrels once took, so any hiccup on that longer passage arrives at Amsterdam's storage gates as thinner receipts rather than a paper shortfall, with no nearby cargo to draw on instead. Gasoil flowing into the hub roughly halved between June and mid-July, and by 15 July the depth of cover held in Amsterdam's own tanks (see ARA for the hub-wide stock count) was thinner than at any point in several years, a physical constraint rather than a trading position.

Amsterdam's blending and storage margins move with the ARA crack, the reference price for how tight Europe's fuel market has become, rather than with crude itself. Moscow tightened its own diesel-export restriction on 8 July to bind domestic producers, not just the trading houses that had handled the flow until then, the same day the crack reached a record.

Brent's flat price slid back under $84 in late July even as the crack kept climbing, a divergence that tells Amsterdam's blenders the constraint sitting in their own tanks is a shortage of finished product, not of crude to refine. The West Mediterranean market ran ahead of ARA's own margin over the same stretch, widening the premium a barrel earns for landing at Amsterdam over the Mediterranean (see Argus Media for the hub-to-hub spread itself).
