So I will admit I am very ignorant of economics, but I am interested in how current events effect currency value.
For example, Saudi Arabia announces it will not renew the petrodollar deal with the US and instead work in multiple currencies including the Chinese yuan. Yet the dollar seems to have increased against the yuan in the last few days.
Russia has been bombarded with constant sanctions and yet they manage to keep their exchange rate at around 1 ruble = .011 USD.
These events seem counterintuitive to someone without knowledge like myself, and I would like to better understand them. Any resources for the theory to help better understand the driving forces behind currency values would be greatly appreciated.
