CPC mixed crude exports are expected to be around 1.5mln bpd in September (prev. 1.5-1.6mln bpd M/M)

CPC loading programmes are watched as one of the cleaner reads on Kazakh and Russian Black Sea supply, and the blend's weight in the Mediterranean and Northwest European light-sour diet means modest month-on-month trims tend to show up first in CPC and regional sour differentials rather than in flat price. The move from a 1.5-1.6mln bpd range to around 1.5mln sits at the low end rather than breaking it, which in past episodes has limited the tightening signal unless confirmed by the final loading schedule. The historical caveat is that preliminary CPC programmes are revised, with outages at the terminal, weather delays on the Black Sea and field maintenance in Kazakhstan all having driven prior variance between initial and final plans. Compliance dynamics also matter: Kazakh output running above quota has repeatedly left CPC loadings firmer than guidance, so Tengiz and Kashagan schedules are the cross-check. Worth noting is whether the cut is supply-led or weather-led, as the former persists into subsequent months and the latter tends to re-load.
