Russia will reroute Kazakh oil exports from Ust-Luga to Novorossiysk to free up Baltic port capacity for additional Russian crude shipments, according to source reports

Rerouting decisions of this kind are as much political as logistical: Kazakh crude moving through Russian infrastructure has historically been hostage to the transit relationship, with past episodes of Russian authorities interrupting or redirecting flows on stated technical grounds during periods of tension. The mechanism here is port and grade substitution: shifting Kazakh volumes from Ust-Luga to Novorossiysk frees Baltic capacity for additional Russian barrels, which under the prevailing sanctions regime means more Urals moving on longer voyages from Baltic loadings rather than into short-haul European buyers. The practical distinction is between the two routes' constraints: Black Sea shipments pass through the Turkish straits, where tanker traffic and inspection regimes have periodically throttled throughput, while Baltic loadings lean more heavily on the shadow fleet and longer-haul Aframax and Suezmax tonnage. Loading programmes are the tell: CPC and Novorossiysk schedules, alongside Urals differentials at each port, reveal whether this is a genuine capacity optimisation or a squeeze on Kazakh transit. Freight rates on both routes and any Kazakh response, given Astana's past efforts to diversify export routes away from Russian territory, are the follow-ons worth tracking.
