Asia stocks fall ahead of Fed decision

Asian markets were lower on Wednesday, in cautious trading ahead of next week's Federal Reserve meeting, while Japan was weighed by a stronger yen.

The region followed the U.S. lower, after stocks on the Wall Street fell overnight as investors sold to cash in some of the strong gains for the year and continued to worry about the potential impact of the Federal Reserve reducing its stimulus.

Speculation over when the Fed will start to roll back its bond-buying program has been a persistent theme in Asia since the early summer, when it sparked a series of selloffs in the region. Recent employment data from the U.S. have been strong, which has raised expectations that the Fed could start to withdraw its stimulus as early as in its December policy meeting next week, giving trading a general air of caution.

This caution could be seen in the dollar's movement against the yen, which pulled back overnight, after spending much of Tuesday with striking distance of challenging its year high. The dollar (USDJPY)   lost a total of 0.4% against its Japanese counterpart overnight and was last trading at ¥102.80, compared with ¥102.84 late Tuesday in New York.

The yen's push back against the dollar weighed on Japanese stocks, with the Nikkei (JP:NIK)  last down 0.4%.
