Weaker yuan seen in 2015

The yuan may depreciate about 2 percent against the dollar this year amid China's economic slowdown, said a report released on Wednesday in Shanghai.

"With robust economic growth, strong expectations of rising interest rates and lagging economic recoveries in many other countries, the US dollar will further strengthen and appreciate against the yuan," said an annual exchange-rate report by Chen Xuebin and Li Huajian, researchers at the Institute for Financial Studies at Fudan University.

The report said the yuan's value against the dollar may fluctuate by 4 to 5 percent in 2015 amid uncertainty over global economic conditions.
