Let us see how the effect will come since Saudi Arabia has dropped their grip on the US dollar.
I bet the Saudis pay in $ when in need for weapons.
They might or they will source it out from other manufacturers that will allow them to pay in whatever currency they want to. But I guess since their alliance with BRICS is at hand and has been vulgar, are they going to purchase it from any of those participating countries that are also into arms manufacturing?
9% of the US Oil comes from Saudi Arabia.
Aside from that, they're also known as suppliers and have one of the biggest shares globally. If my research is right, it's about 16% or so as per the global share that they're doing for the entire world. That's a lot of share coming from them.
