The yen rose 0.7 percent
to 117.11 per dollar in Tokyo from 13 Jan. It strengthened for a fifth
day against the euro, climbing 0.6 percent to 138.04
yen. The euro was little changed at $1.1789 after it touched $1.1753 yesterday,
the least since December 2005.
The Aussie dropped 0.9 percent
to 80.88 U.S. cents after copper fell below $5,400 a metric tonne in London, the
lowest level since July 2009.
The yen is the best performer in the past month
against nine developed-nation. It has risen 5.7 percent amid increased demand for haven assets amid a
plunge in oil and declines in global stock markets. The euro has fallen 2.2 percent in the period, while the dollar gained 4 percent.
The Japanese stocks fell following declines in oil
and copper to the lowest levels since 2009.
If stocks continue to slump on the idea that low oil prices will become a risk to the U.S. or the global
economy, dollar-yen will continue to fall.
