In a surprising move, Russia has slammed the brakes on exporting diesel fuel and gasoline to most countries.
This sudden ban could mess up for fuel supply just as winter approaches and make the global fuel shortage even worse.
Russia, one of the big dogs in the diesel world, says this ban is temporary. But here's the catch, they didn't give an end date.
This ban kicked in right away and applies to almost all countries except for Belarus, Kazakhstan, Armenia, and Kyrgyzstan.
These countries are in a club with Russia called the Eurasian Economic Union.
Why did they do it? Russia says they want to keep fuel prices stable back home.
But experts are scratching their heads because the language used in Russia's announcement is pretty vague.
Some folks worry that Russia might be playing games with our fuel supplies, especially when winter's chill starts to bite.
Before Russia's big move, they used to ship out a whopping 2.8 million barrels of diesel every day.
That's a ton of fuel! But lately, it's been more like 1 million barrels a day.
Experts are worried about this because winter usually means more people need fuel to keep warm.
Plus, there's already not enough diesel in the world right now. So, this ban might make things worse.
One expert said, "The loss of around 1 million barrels per day of Russian diesel in the global market will be felt." That means we might feel the pinch when we go to fill up our cars or heat our homes.
Russia isn't the only player in this game. OPEC top seat Saudi Arabia and Russia both said they're cutting down on their oil exports.
Some folks think Russia's ban might have something to do with recent trouble they had at the UN.
Others wonder if Russia is trying to use energy as a weapon, like they did with gas supplies to Europe in the past.
