The foreign currency denomination of contracts in international transactions can lead to international currency exposure at the country level with important economic and policy implications. When debts are denominated in foreign currency and revenues in domestic currency, exchange rate fluctuations can result in balance sheet effects for countries with either net asset or liability positions. Moreover, currency mismatch between assets and liabilities can be a cause for crises in developing and emerging economies.

They consider international currency risk after the Swiss franc ended its one-sided peg with the euro, for example, and the foreign exchange positions of firms in Turkey and Russia. Other contributors take macroeconomic perspectives, examining the potential effects of exchange rate realignment, the pressure to appreciate on countries with current account surpluses, and the currency exposure in international trade. Finally, contributors consider the issue from finance and political economy perspectives, addressing the phenomenon of the forward premium puzzle and discussing geopolitical aspects ascending currencies.ContributorsFatih Altunok, Huseyin Aytug, Agustin S.
