TOKYO, Sept 8 (Reuters) - The dollar rose to a one-week peak against major peers on Wednesday, buoyed by higher Treasury yields and a weaker euro ahead of a European Central Bank policy decision. The dollar index , which measures the currency against six rivals, ticked up 0.05% to 92.580, after earlier touching 92.590, a level not seen since Sept. 1.

The dollar index had tumbled to its lowest levels since early August at the end of last week, when a surprisingly soft U.S. payrolls report prompted speculation the Federal Reserve will forgo announcing a taper of stimulus at a policy meeting this month.

This week"s dollar strength appears to be the result of a shift in investor focus to wage growth, which "suggests that the Fed may stick with its tapering plan," Ken Cheung, a strategist at Mizuho Bank in Hong Kong, wrote in a report. "We look for further upside for the USD." However, the surge in COVID-19 deaths in the United States could give the central bank pause.
