    Feb 16 (Reuters) - Gold prices edged higher on Friday,
heading for their biggest weekly percentage gain in nearly two
years, buoyed by a weaker U.S. dollar and as investors looked to
hedge against inflation.
    Spot gold        was up 0.4 percent at $1,358.40 an ounce as
of 0801 GMT, after touching a three-week high of $1,360.
    The metal is up more than 3 percent this week, set for its
best weekly performance since the week ended April 29, 2016.
    U.S. gold futures         climbed 0.4 percent to $1,360.90
per ounce on Friday.
    Spot gold has gained 4 percent from a one-month low of
$1,306.81 last week, mostly on a weaker dollar. 
    "Gold has risen this week mainly due to a weaker dollar and
physical buying ahead of Chinese New Year," said Amit Kumar
Gupta, portfolio management services head at Adroit Financial
    "Also, the market is starting to fall in love with inflation
trades again. Gold could be the standout performer this year if
that's the case though some wearing off can come once the
seasonal buying is done," Kumar said.
    The dollar slipped to a three-year low against a basket of
currencies on Friday, and was headed for its biggest weekly loss
in two years, as bearish factors offset support the U.S.
currency could take from rising Treasury yields.        
    U.S. producer prices accelerated in January, boosted by
strong gains in the cost of gasoline and healthcare. The Labor
Department said its producer price index for final demand rose
0.4 percent last month after being unchanged in December.
    In a second report, the Labor Department said initial claims
for state unemployment benefits increased by 7,000 to a
seasonally adjusted 230,000 for the week ended Feb. 10.
    "A combination of rising inflation, coupled with slightly
weaker U.S. growth readings and a struggling dollar should
continue to provide gold with an element of support," INTL
FCStone analyst Edward Meir said.
    Holdings of SPDR Gold Trust      , the world's largest
gold-backed exchange-traded fund, fell 0.29 percent to 821.30
tonnes on Thursday from Wednesday. 
    "Technically, the January 2016 high was $1,365 and the 2016
high was $1,375 ... If gold can clear both those levels, there
is lot of room above," Gupta of Adroit said.
    Among other precious metals, spot silver        was up 0.3
percent at $16.92.
    Platinum        was 0.8 percent higher at $1,008.90, after
hitting its highest since Jan. 29 at $1,009.80.
    Palladium        was up 0.7 percent at $1,025. The metal has
gained 5 percent this week, its best since the week ended Oct.
