* San Francisco Fed's Williams say Fed could end QE this
* Dollar index near its July peak
* Dollar/yen near 4 1/2-year high, euro near 6-week low
By Anirban Nag
LONDON, May 17 The dollar rose against a basket
of currencies on Friday, hovering near a 10-month high as debate
over whether the Federal Reserve would wind down its asset
buying programme later this year gathered pace.
The dollar's strength, along with expectations that the
European Central Bank could introduce negative deposit rates,
the rate at which banks park surplus funds with it, kept the
euro pinned down to recent six-week lows.
The dollar index, which measures its value against a
basket of six major currencies, rose 0.4 percent to 83.886,
nearing a 10-month high of 84.094 set on Wednesday. A break of
its July peak of 84.10 would see it rise to its highest in
nearly three years.
The dollar was up 0.2 percent at 102.51 yen, not far
from Wednesday's 4-1/2-year high of 102.77 yen.
Investors added to favourable bets in the dollar, drawing
support from comments by a regional Federal Reserve chief who
said the Fed could begin easing up on stimulus this summer.
John Williams, the president of the San Francisco Fed, said
the U.S. central bank could completely exit its easing by the
end of the year.
Although Williams is not a voter this year at the Federal
Open Market Committee, his views carry weight as they are often
considered close to Fed's top officials such as Chairman Ben
Bernanke and Vice Chair Janet Yellen.
Bernanke and Yellen want to keep monetary policy ultra-loose
for a longer period of time, while others like Richmond Fed
chief Jeffrey Lacker say the economy's prospects are looking
better and the pace of asset purchases can be reduced.
"His comments took the market by surprise since he is a
dove," said Peter Kinsella, currency strategist at Commerzbank.
"It is a dollar story this year as the U.S. labour and
housing markets appear to be recovering. And while we do expect
the Fed to be cautious in withdrawing stimulus, the economic
recovery should drive the dollar higher."
A resurgent dollar pushed the euro near a six-week low. The
common currency stood at $1.2870, not far from a six-week
low of $1.2843 hit on Wednesday, with buying by Middle-East
investors slowing its decline.
"We have a negative arrow on the euro today primarily
because the dollar remains in demand and ECB speakers today,"
said Chris Turner, head of currency strategy at ING. "Anyone
could be asked about negative deposit rates and repeat (ECB
chief) Mario Draghi's line that the ECB is technically ready."
Lowering the deposit rate to negative would make holding
euros unattractive and lead to a broad sell off, traders say.
ECB board members, Beniot Coeure, Yves Mersch, Joerg
Asmussen and Peter Praet are due to speak at various times of
the day and could fuel debate over whether the ECB is likely to
introduce negative deposit rates in coming months.
The euro held its ground against the struggling Australian
dollar, rising 0.6 percent to a 1 1/2 year high of
A$1.3219. The Aussie has lost considerable ground as
hedge funds have sold it aggressively in recent weeks. It was
trading down 0.6 percent at $0.9741, a 11-month low.
