PRECIOUS-Gold prices flat as investors brace for large U.S. rate hike

    Sept 21 (Reuters) - Gold prices lingered near recent lows on
Wednesday as investors prepared for the likelihood of another
super-sized interest rate hike from the U.S. Federal Reserve in
its effort to tame soaring inflation.
    * Spot gold        was flat at $1,663.73 per ounce, as of
0126 GMT. Bullion hovered close to $1,653.10, its lowest level
in more than two years marked last week.
    * U.S. gold futures        edged 0.1% higher at $1,686.70.
    * The dollar index        was steady, holding close to a
20-year high hit earlier this month. A firmer greenback makes
bullion more expensive for other currency holders.       
    * The Fed's two-day policy meet will conclude on Wednesday,
with rate futures traders pricing in an 81% chance of a 75
basis-point hike and a 19% probability of a 100 bps increase.
    * Higher interest rates increase the opportunity cost of
holding non-yielding bullion and boosts the dollar. 
    * The European Central Bank may need to raise interest rates
to a level that restricts economic growth in order to cool
demand and combat unacceptably high inflation, ECB President
Christine Lagarde said on Tuesday.             
    * Swiss exports of gold to top consumer China fell in August
from July's 5-1/2-year high, while shipments to Turkey rose to
their highest since June 2013, Swiss customs data showed on
    * Holdings of SPDR Gold Trust      , the world's largest
gold-backed exchange-traded fund, fell 0.48% to 953.32 tonnes on
Tuesday from 957.95 tonnes on Monday.             
    * Spot silver        fell 0.3% to $19.26 per ounce, platinum
       rose 0.2% to $924.10 and palladium        was down 0.9%
at $2,149.01.
