CANADA FX DEBT-C$ rallies to 3-1/2-month high

* C$ touches C$0.9852 vs US$, or $1.0150
    * Bond prices retreat across the curve

    TORONTO, Aug 21 (Reuters) - The Canadian dollar climbed to a
three-and-a-half-month-high against the U.S. dollar on Tuesday,
tracking global equities, commodities and other commodity-driven
currencies higher as a stream of encouraging headlines lifted
    The Australian and New Zealand dollars got a boost after the
Reserve Bank of Australia sounded content with policy where it
was, while talk of stimulus measures in regional China
underpinned risk appetite. 
    Meanwhile, talk the European Central Bank will take strong
action to ease Spanish and Italian borrowing costs was also
being telegraphed to markets. 
    "I would say there isn't one catalyst but a slew of
catalysts which have helped the risk rally," said Camilla
Sutton, chief currency strategist at Scotiabank.
    She cautioned however that near term, the currency's recent
surge could be overdone.
    "Anything we measure it against, all the fundamental drivers
for CAD are positive for CAD which is good, however if we look
at it on any of the charts, it's really overstepped its rally,"
added Sutton, noting correlations to oil and other commodities,
and interest rate spreads.
    At 8:19 a.m. (1219 GMT), Canada's dollar was at C$0.9861
versus the U.S. dollar, or $1.0141 U.S. cents, firmer than
Monday's North American session close at C$0.9884 versus its
U.S. counterpart, or $1.0117.
    The Canadian dollar hit an intraday high of C$0.9852, or
$1.0150, its firmest level since May 3.
    Sutton eyed the Canadian dollar's range for the day between
C$0.9840-C$0.9890 against the greenback.
    Wednesday's Canadian retail sales data, comments from Bank
of Canada's Mark Carney when he speaks to the Canadian Auto
Workers union and the U.S. Federal Reserve's FOMC minutes could
all be factors in the currency's direction. Market watchers will
look closely for any change in the Canadian central bank's
perceived tightening bias.
    Fed Chairman Ben Bernanke's speech in Jackson Hole, Wyoming,
on Aug. 31 is seen as a major event. On the domestic front, all
eyes will also be on the Bank of Canada policy decision and the
Quebec election.
    Canadian bond prices retreated across the curve, tracking
U.S. Treasuries down as investors preferred riskier assets.
    The two-year bond was down 5 Canadian cents to
yield 1.214 percent, and the benchmark 10-year bond 
fell 27 Canadian cents, yielding 1.967 percent.
