Yen Rises on Rebound in Tertiary Sector Activity, Korean Won Falls Despite Interest Rate Rise

The yen strengthened against the U.S. dollar on Friday after the Japanese tertiary sector activity rebounded in May. At around 6 am GMT, the greenback lost 0.3% of its value to trade around ¥80.1250 against the Japanese currency. The yen was pushed higher by news of a strong rebound in its tertiary sector. According to

, Japan's tertiary sector activity rose by 2.6% in May, following a 5.9% fall in April. Analysts were predicting a slightly stronger rebound of 2.7%, however. The tertiary sector activity data follows a string of encouraging data for the Japanese economy.

In spite of an increase in interest rates, the Korean won lost some ground against the U.S. dollar. At around 6 am GMT, the U.S. dollar rose 0.26% to 1082.90 against the won. The Korean economy is exports-oriented and if interest rates continue to rise, pushing the value of the won higher, the country's exporters will start to lose their competitive edge. This is a scenario the Korean authorities will surely like to avoid.
