Problem 4: International Finance For each of the following, include both a verbal explanation and a relevant foreign exchange supply-demand diagram: a) How will it affect the value of the US dollar if the Fed's Open Market Committee (somewhat surprisingly) decides to increase the federal funds rate by an additional 0.25% in June 2023? b) How will it affect the value of the Pound Sterling if the UK announces expansionary monetary policy that markets predict to be inflationary? c) How will it affect the value of the Brazilian real if Brazil's central bank increases interest rates, but markets view this as a "desperate" move revealing that the real is in a more fragile condition than had been previously assumed?
