The FT reports that Leonid Fedun, vice-president of Lukoil says Russia's oil production has peaked.
Why does that matter? Because Russia is the world's second largest oil producer, just a shade behind Saudi Arabia, and a shade in front of the USA. All these countries produce more than double the amount that Iran, placed fourth, does. It's also the second largest oil exporter, way ahead of Norway (yes, Norway) in third place.
The USA's production peaked decades ago, and Saudi Arabia is notoriously secretive about its reserves and future production capacity, and there's been a notion that we're going to increasingly rely on Russia for energy in the future. Well, not now, we're not. Basically, the future of oil is down to whether Saudi Arabia can turn up the the pumps, or whether some new reserves will magically appear.
