The risk of currency exchange rate distortion encountered in international trade is particularly prominent in a large number of countries. The currency exchange rates are often greatly affected by political and economic factors, resulting in sharp exchange rate fluctuations, which brings tremendous risks to importers, exporters and investors.
For a long time the U.S. dollar has been one of the dominant reserve currency, and about half of international trade is invoiced in dollars, and about half of all international loans and global debt securities are denominated in dollars [1]. However, many countries do not have sufficient U.S. dollars reserves. Thus they often face threat of foreign debt crisis and inflation. These problems will further exacerbate the risk of instability and distortion of their national currency exchange rates.
Due to aforementioned factors, the countries will face great difficulties in international trade. And in plenty of cases, those countries are often forced to take measures to devalue their currencies to maintain trade balance. In general, a weaker currency makes imports more expensive, while stimulating exports by making them cheaper for overseas customers to buy. A weak or strong currency can contribute to a nation's trade deficit or trade surplus over time [2].
The risk of exchange rate distortion and insufficient U.S. dollars reserves are two of the most common and biggest problems encountered in a lot of countries in international trade. These problems not only affect importers, exporters and investors, but also have a huge impact on the economic and social development of the countries.
