Russia's decision to ban exports of diesel and gasoline risks disrupting fuel supplies ahead of winter, but how deep the impact will be depends on how long it lasts.

The nation shipped more than one million barrels a day of diesel-type fuel so far this year, narrowly making it the world's biggest seaborne exporter, according to data from Vortexa. That's an enormous chunk of supply for the market to lose at short notice roughly enough to meet the entire demand of Germany.
