New York: The US dollar soared to an eight-month high as remarks by a Federal Reserve official bolstered market expectation for an interest-rate hike by year-end.

San Francisco Fed President John Williams said during the weekend that there is a "strong case" for the Fed to raise rates when policymakers meet next month.

On the economic front, US existing-home sales in October were at a healthy pace but failed to keep up with September's jump, according to the National Association of Realtors on Monday.

Despite last month's decline, sales are still 3.9 percent above a year ago.
