Russia cuts crude output 300,000-400,000 bpd as Ukrainian drones hit Ust-Luga, Primorsk and Novorossiysk

Analysis
The sharpest monthly production cut since COVID-era discipline, corroborated across Moscow Times and Bloomberg, with independent IEA methodology as a distinct confirming source, marks a shift from the 40-percent export-capacity peak disruption of late March to sustained structural impairment: Ukrainian deep-strikes on export terminals and inland refineries are imposing a non-trivial revenue cost that complicates the 2026 FSB budget and reserve-fund drawdown pace. The IEA's 120,000 bpd supply-forecast revision for the remainder of the year very likely understates the compounding effect if Kyiv sustains strike tempo through summer; Europe's winter heating cycle is unaffected given the distinct transit architecture, but Asian refiners face narrower Russian crude availability and a likely $2–4/barrel tightening of Chinese and Indian discounts over coming months. Moscow may be using strike attribution to cover discretionary production discipline aimed at propping global prices, in which case the true drone-attributable share is materially smaller, but the convergence across independent sources favors the structural-impairment read over the price-management hypothesis.
