NEW YORK, April 4 (Reuters) - Gold rose and silver surged
to 31-year highs on Monday, as fresh gains that pushed oil and
grain prices to their highest since 2008 stoke inflation
worries.
While silver streaked ahead, rising to its strongest
relative to gold since 1983 after the Hunt Brothers cornered
the silver market, bullion prices have struggled for the past
month to sustain new highs.
Activity in the U.S. futures market on Monday was less than
half the average, set to be one of the weakest this year, as
the metal struggled to extend its record high $1,447.40 an
ounce set on March 24.
"There is no question that the inflation factor is
supporting gold," said Bruce Dunn, vice president of precious
metals dealer Auramet Trading. "Both gold and silver are
benefiting from speculative buying and good demand from
physical bars and coins."
Spot gold <XAU=> rose 0.3 percent to $1,432.24 an ounce by
2:06 p.m. EDT (1806 GMT), off an earlier high of $1,438.55 an
ounce.
U.S. gold futures for June delivery <GCM1> settled up 0.3
percent to $1,433.
Rising oil and grain prices boosted gold's inflation hedge
appeal. U.S. oil rose to a 2-1/2-year highs on geopolitical
risks to supply from the Middle East, while corn futures
rallied to the highest level since the 2008 global food crisis
due to very tight supplies. [] []
Silver <XAG=> climbed to its highest in 31 years at $38.58
an ounce, sending the gold-to-silver ratio to its lowest level
in 18 years. It was later up 2 percent at $38.48.
Silver prices are fast closing in on $40 an ounce, lifted
by interest in the metal as a cheaper proxy for gold and
expectations that industrial demand is set to improve. But
analysts remain wary of silver's extreme volatility, which has
led to some heart-stopping reversals in recent years.

ECB RATE HIKE, DOLLAR STRENGTH EYED
Bullion rose as the the euro hovered near a five-month peak
against the dollar, with the ECB expected to raise rates by 25
basis points from a record low in reaction to rising
inflationary pressures in the euro zone, with two more 25 basis
point hikes factored in by year-end. <ECBWATCH> []
Bullion investors chose to side with expectations of a
weakening dollar after the ECB meeting this week, as rising
interest rates are generally negative for gold, as they raise
the opportunity cost of holding non-yielding assets.
Gold is also benefiting from concerns some smaller euro
zone economies such as Portugal and Ireland will continue to
struggle with sovereign debt, and from unrest in the Middle
East and North Africa.
For platinum group metals, platinum <XPT=> rose 0.9 percent
to $1,781.49 an ounce, while palladium <XPD=> gained 1.3
percent to $780.22.
