NEW YORK (Reuters) - The dollar rose to a three-week high against a basket of currencies, and a one-month high against the yen, on Tuesday as investors looked ahead to crucial jobs data this week for clues on when the Federal Reserve will next raise interest rates.
Hawkish comments on Friday by Fed Chair Janet Yellen and Vice Chair Stanley Fischer increased expectations the U.S. central bank could hike at its September policy meeting, though most investors and economists view a single increase at the December meeting as more likely.
The next key indicator is Friday's jobs report for August, which is expected to show employers added 180,000 jobs in the month, according to the median estimate of 89 economists polled by Reuters. [ECONUS]
"We had a bit more hawkish tone from Yellen at Jackson Hole and that was reinforced by Fischer,” said Mark McCormick, North American head of FX strategy at TD Securities in Toronto.
"The market is refocusing itself on the upcoming data releases and I think that's helping a rethink of where the Federal Reserve's is going to be in the second half of the year,” he said.
Friday's jobs data will be preceded on Wednesday by the ADP National Employment Report of private-sector payrolls.
Fischer, who said that the data could weigh on any rates decision, gave no fresh clues on timing in a television interview on Tuesday. He said the U.S. job market is nearly at full strength and the pace of Fed rate increases will depend on how well the economy is doing.
The dollar index, which measures the currency against a basket of six majors, rose as high as to 96.143 <.DXY>, its highest level since Aug. 9, before falling back to 96.062, up 0.50 percent on the day.
The greenback gained 1.1 percent against the yen to 103.01 <JPY=>, after earlier hitting 103.13, the highest level since July 29. The yen was also held back by comments from policymakers worried about its recent strength.
Japan's Chief Cabinet Secretary Yoshihide Suga told Reuters in an interview that the government will respond "appropriately" to unwelcome yen gains that hurt economic growth.
Koichi Hamada, an adviser to Prime Minister Shinzo Abe, said the Bank of Japan could consider buying foreign bonds as an option to weaken the yen, if government intervention in the currency market is deemed by the United States to be exchange rate manipulation.
