It gets more bizarre though. Putting aside economics, the US, the Saudis and the Iranians all have a pretty aligned geo-political reason for pumping the oil hard: ISIS.
Politics and war make strange bedfellows.
It's a very ballsy move, but it's also a very dangerous one, because the Saudi regime relies heavily on direct patronage - handouts - and if those stop happening there's a real danger of instability.
It's also very dangerous to poke Russia too hard, because Putin really isn't likely to say "Fine then, I'll just give up."
This could all end very badly for everyone.
So they've decided to fight for market-share this time. And they can, since their production prices are on the low side.
But so if there's only so many barrels of oil going to be sold, then at this point it really is an all-out scrap for market share. Maybe Saudi Arabia is aiming to just to divest themselves of the majority of their reserves while volumes like that can still be moved at all, i.e., over the next 20-50 years.
If this is a 20 year game then it's time for bold moves.
Syria's production is close to Belarus's production and behind Cuba's. And even before its decline it was behind Ukraine's production.
It's not a big enough player for anything. Especially for a juggernaut like Russia.
