Yen Slides Amid Risk Appetite

The Japanese yen weakened against other major currencies in the European session on Thursday amid risk appetite, as European leaders debate ways to ramp up sanctions against Iran.

"We need to adapt and expand them," French President Emmanuel Macron said of sanctions the EU has already slapped on the Islamic Republic.

Israel would make its own decisions on potential retaliation for Iran's unprecedented attack, prime minister Benjamin Netanyahu has said - hours after David Cameron landed in Israel for talks, urging restraint.

In economic news, data from the Ministry of Economy, Trade and Industry showed that Japan's tertiary activity index increased at a faster-than-expected pace in February. The seasonally adjusted tertiary activity index rose 1.5 percent month-on-month in February, reversing a 0.5 percent decrease in January. Economists had expected a 0.8 percent increase.

On a yearly basis, the tertiary activity index increased at a faster pace of 2.5 percent in February after a 1.0 percent gain in the prior month. Moreover, it was the quickest increase in six months.
