HONG KONG, Aug 11 (Reuters) - The dollar and U.S. yields extended gains in Asia on Wednesday, spurred by tapering talk, while Asian shares traded sideways on fears about the spread of the coronavirus despite a record close on Wall Street.
The dollar index rose to its highest since mid July, gaining against the yen , while the euro neared year-to date lows against the greenback.
Improving U.S. economic data and a more hawkish tone from Federal Reserve officials have led markets to expect the central bank to begin tapering its asset purchases later this year, pushing up yields and supporting the dollar.
But the move has been well flagged, meaning a repeat of the so-called "taper tantrum" of 2013 that shook markets when the Fed began putting the brakes on its quantitative easing program, is unlikely said Ray Farris, chief investment officer South Asia, Credit Suisse.
"In Asia there's a little bit of concern about tapering but there is increasing understanding that we're unlikely to get a tantrum," said Farris.
"But there is a lot more concern about Delta because of its impact on a lot of Asian economies where vaccination rates are lower," he said.
The Delta variant of the new coronavirus is spreading quickly in many Asian countries raising fears about local travel restrictions, hurting the economic recovery.
