Reading an article by Cline and Perry (2013) I came across a paragraph about the relationship between oil prices, the Dollar and of course Exchange rates.
In this article aptly named “Wages, Exchange Rates, and the Great Inflation Moderation: A Post-Keynesian View” Cline and Perry argue that oil is endogenous through the effects of the exchange rate. When oil is sold by OPEC countries they receive dollar denominations, which then need to be converted into the local currency. It is argued that as the dollar falls in value OPEC oil prices rise to meet profit quotas.
Therefore as the dollar falls in value the price of oil rises. It is also argued on the other hand that when the dollar rises in value OPEC increase the production of oil, therefore decreasing its price.
Let me know your thoughts on this relationship: @Breadeconomics
