Asian stocks fell on Wednesday ahead of the Fed's rate call later today as the chances of a Donald Trump victory in the Presidential elections appeared to increase.

U.S. futures were also down, with the Dow Jones down 0.26%, S&P 500 mini futures  0.29%  lower and Nasdaq 100 futures off 0.25%. The Fed is seen unlikely to change rates today, when it will deliver its verdict during the U.S. afternoon.

The dollar was down 0.24% against the yen at ¥103.9000 after an equities selloff on Wall Street on Tuesday. An ABC/Washington Post poll yesterday put Republican Trump one percentage point ahead of Democratic Presidential candidate Hillary Clinton, though other polls suggest Clinton has a narrow lead. Clinton lost ground after the FBI last week reopened an investigation into her use of her private email server.
