Monday as the dollar firmed, though the market is focused on the
outcome of the U.S. presidential debate later in the day, that
could see investors buying more of the metal as a hedge against
financial uncertainty.
    Spot gold slipped 0.1 percent to $1,336 an ounce at
0719 GMT. U.S. gold futures slid 0.2 percent to $1,339.9
an ounce.

    The first U.S. presidential debate between Republican Donald
Trump and Democrat Hillary Clinton will take place at 0100 GMT
on Tuesday, with investors looking for indications of who could

likely to keep gold underpinned," said Alex Thorndike, senior
precious metals dealer, MKS PAMP Group.
    The dollar index, which measures the greenback
against six major currencies, was up 0.05 percent at 95.521.

$1,340 range in the lead up to the presidential debate," MKS
PAMP Group trader Sam Laughlin said in a separate note.
    Boston Federal Reserve President Eric Rosengren said on
Friday that he believed interest rates should be raised
gradually now and warned that a fall in the unemployment rate
below its sustainable level could derail economic recovery in
the United States. 
    The split at the Federal Reserve over when to next raise
interest rates appears to hinge largely on disagreements over
the labour market outlook, comments from policymakers on Friday
    Gold is highly sensitive to rising rates, which lift the
opportunity cost of holding non-yielding assets such as bullion,
while boosting the dollar, in which it is priced.
