2. I am the central bank of A. I want to keep my exchange rate with B fixed. If something happens that means people would not want my currency. I would have to buy B currency to keep the exchange rate fixed.
3. I am the central bank of A. I want to keep my exchange rate with B fixed. If something happens that means people would not want my currency. I would have to decrease my reserves of B currency to keep the exchange rate fixed.
4. I am the central bank of A. I want to keep my exchange rate with B fixed. If something happens that means people would not want my currency. I would eventually have no choice but to devalue my currency, close my borders to international markets, or beg the IMF for a loan.
