Many of Asia's currencies are losing value against the United States dollar this year.But experts say governments are managing the losses better than they did in the past.The currencies of China, India, Indonesia and Myanmar all have lost value since January of 2018.The Indian rupee was at a record low against the U.S. dollar in June.And the Chinese yuan lost 3.2 percent in the first half of the year.Economists say there are many reasons for this, including possible contagion from financial problems in Turkey.They also say investors are worried about the effects of the trade dispute between the United States and China.Next week, China will face additional U.S. tariffs on $16 billion-worth of Chinese products.Song Seng Wun is an economist with investment bank CIMB in Singapore.He said, "It's just basically that everything we've worried about now and then sort of converged."
