Hi, not neccessary
you can talk about how fiscal policy can be used to stimulate economic growth encouraging imports which could see a depreciation. You could give an example as in 2007 prior to the GFC, economic growth had seen the dollar fluctuate between 95c, not going higher.
yeah, i mentioned m.p and how it appreciates/depreciates with change in cash rate
also, how many trends woudlve been appropriate to mention in this essay? i didnt have any graphs either
