At current interest rates and exchange rates, the US might have a $400 billion net financial (capital) account inflow from the rest of the world during 2010, and therefore a matching $400 billion trade (current account) deficit.
a. Explain why the size of the net US financial inflow has to approximately match the size of the US current account deficit, because of how the foreign exchange markets work.
b. Explain what might happen to both of these imbalances if the Chinese yuan is significantly revalued upwards against the dollar, revalued by the central bank of China and other Chinese agencies that hold massive reserves of dollars and yuan. Explain the cause-effect of why your proposed changes in these imbalances would occur.
