The financial markets profit form both rises and falls in exchanges rates. But when the value falls across the board all business profits and share values fall.

It is therefore imperative that market regulators and govements act together to avoid financial crashes sush as the one in 2008 which has required several huge interventions of the fiscal stimulus to avoid another damaging crash.
