2. Suppose that Brazil, which is running a current account (CA) deficit of $4 billion and a balanced capital account, is initially in a balance of payment equilibrium. a) What is Brazil's financial account (FA) balance? For each of the following economic actors, suggest one way through which they can help Brazil obtain the foreign currency it needs to cover its current account deficit: i. Foreign investors ii. Brazilian investors iii. Foreign central banks Now, assume that foreign investors reduce their holdings of Brazilian reais (the domestic currency) by selling $1 billion worth of Brazilian reais in the foreign exchange market. b) What is the immediate impact of such action on the CA or FA of Brazil, assuming that the value of the Brazilian real has not adjusted against foreign currency yet? c) Is there a temporary overall balance (OB) surplus or deficit for Brazil? Is it an excess supply of or demand for foreign currency? d) If Brazil has a flexible exchange rate, what would happen to the value of the Brazilian real (against foreign currency)? Use the foreign exchange (FX) diagram to illustrate your answer. Be sure to indicate the initial $4 billion CA deficit/FA surplus on the diagram..
