SYDNEY (Reuters) - The U.S. dollar jumped in Asia on Monday after FBI Director James Comey said a review of newly discovered emails did not change the agency's conclusion that no charges were warranted in the case of Hillary Clinton's use of a private email server.

The dollar climbed about 1 percent against the yen to 104.05 <JPY=>, while the euro slipped 0.6 percent to $1.1066 <EUR=>.

Markets have tended to see Democratic contender Clinton as the status quo candidate for U.S. President and news favoring her bid often boosts risk appetite.

In a letter to Congress, Comey said on Sunday the agency had completed its review of the new emails and "we have not changed our conclusions that we expressed in July with respect to Secretary Clinton".
