📝 Resumen ejecutivo
ExxonMobil signaled that Kazakhstan's largest oil field will hit peak production within years, pointing to a plateau and eventual decline in output from a major non-OPEC supplier. The warning deepens concerns over long-term global crude supply as mature fields and underinvestment constrain future growth. Brent and WTI find support if Kazakh volumes taper ahead of schedule, while Exxon's own production outlook faces downgrade risk.
