SINGAPORE, May 17 (Reuters) - The dollar held firm near a 10-month high versus a basket of currencies on Friday after a U.S. Federal Reserve official said the central bank may begin to taper its asset buying this summer, while Asian shares were mixed.
U.S. equities had sagged on Thursday after John Williams, president of the Federal Reserve Bank of San Francisco, said the Fed could begin easing back on the monetary gas pedal this summer and end bond buying late this year.
Although Williams does not have a vote in the Fed’s policy-setting panel this year, his comments had weighed on shares, since the Fed’s purchases of $85 billion a month in bonds has been a significant driver of the rally in equities that has taken U.S. stock indexes to record highs this year.
The dollar index, which measures the dollar’s value against a basket of currencies, rose 0.4 percent to 83.927, nearing a 10-month high of 84.094 set earlier this week.
The dollar’s strength will probably become more prominent later this year, said Sim Moh Siong, FX strategist for Bank of Singapore.
“What we’re seeing right now is more of a rehearsal. It’s likely to pan out on a more sustained basis by late this year,” he said.
“Eventually I think the broad tone of data should show that the U.S. economy is holding up much better than the rest of the world and that would lend more durable support for the U.S. dollar,” he said.
The dollar is likely to gain support particularly against other low-yielding currencies such as the euro, the yen, sterling and the Swiss franc, he added.
In the stock market, MSCI’s broadest index of Asia-Pacific shares outside Japan fell 0.3 percent to 479.75, inching away from last week’s high of 491.17, its strongest level since July 2011.
Japan’s Nikkei share average erased its earlier losses and edged up 0.3 percent, holding near a 5-1/2-year intraday high set on Thursday. The main index in the Philippines fell 0.7 percent, down for a second straight day after having set a record closing high on Wednesday.
Markets in South Korea and Hong Kong were closed on Friday for public holidays.
Spot gold eased to about $1,380 an ounce. Gold had hit a four-week low near $1,369 on Thursday as renewed liquidation in gold ETFs and the recent drop below the $1,400 per ounce level hurt sentiment.
U.S. crude futures slipped to about $95 a barrel.
Economic data the previous day had stirred some negative sentiment about the U.S. economy.
Factory activity contracted in the mid-Atlantic region in May, ground-breaking for new homes tumbled in April and new claims for jobless benefits spiked last week, according to three separate reports.
Coupled with soft underlying inflation, the data suggested weak demand as the U.S. economy entered the second quarter.
