Please find below answer to your question
Introduction
The exchange rate has an effect on the trade surplus or deficit, which in turn affects the exchange rate, and so on. In general, however, a weaker domestic currency stimulates exports and makes imports more expensive. Conversely, a strong domestic currency hampers exports and makes imports cheaper
In following ways exchange rates are considered a self-correcting mechanism of international trade
1) The importing and exporting activity of a country can influence a country's GDP, its exchange rate, and its level of inflation and interest rates.
2) A floating exchange rate is determined by the private market through supply and demand of goods in international trade
3) A fixed, or pegged, rate is a rate the government (central bank) sets and maintains as the official exchange rate and that can lead to growth and higher demand of international trade
4) The reasons to peg a currency are linked to stability. Especially in today's developing nations, a country may decide to peg its currency to create a stable atmosphere for foreign investment and ultimately it will boost the activities related to international trade
5) If, for example, it is determined that the value of a single unit of local currency is equal to US$3, the central bank will have to ensure that it can supply the market with those dollars. In order to maintain the rate, the central bank must keep a high level of foreign reserves
6) Exchange rate ensure an appropriate money supply, appropriate fluctuations in the market (inflation/deflation) . The central bank can also adjust the official exchange rate when necessary.
