LONDON, March 11 (Reuters) - Gold slipped alongside oil on
Friday but was supported after a major earthquake struck Japan
and investors fretted about unrest in the Middle East.
It is on track for its biggest weekly decline since early
January, down about $30 since hitting a lifetime high of
$1,444.40 a troy ounce on Monday.
Spot gold <XAU=> was bid at $1,409.00 an ounce at 1054 GMT
from $1,412.59 at the close on Thursday.
The biggest earthquake to hit Japan since records began 140
years ago struck the northeast coast, triggering a 10-metre
tsunami that swept away everything in its path, including
houses, ships, cars and farm buildings. []
"Gold is trading off oil, but Japan's earthquake and tension
in the Middle East is helping," said Andrey Kryuchenkov, an
analyst at VTB Capital. "Markets are nervous also with a planned
'day of rage' in Saudi Arabia."
Investors are watching to see what happens in Saudi Arabia,
where a planned day of demonstrations will test whether
activists calling for political reform will succeed in taking
their protests to the streets. [] []
Also on the radar was Libya, where a sea and tank assault
was launched on the oil port of Ras Lanuf overnight,
intensifying a counter-offensive against the out-gunned
insurgents. []
"Historically, those sort of events in the Middle East have
tended to be quite supportive," said Michael Lewis, head of
commodity research at Deutsche Bank.
"But the effect will probably fade quite quickly."

The yen fell broadly and slumped to a two-week low against
the dollar and Brent futures slipped after the earthquake as
investors retreated from assets they see as risky. [] []
A stronger dollar makes dollar-denominated commodities
cheaper for holders of other currencies, while gold is used as a
hedge against inflation, often triggered by rising oil prices.
But neither of these was in play on Friday.
"There have been signs of some profit taking and scrap
sales, but the market remains tight. Focus is concentrated on
the Middle East; any sign of resolution will take some froth off
the gold market," Standard Bank said in a note.
"Private investors have bought (silver) as a more affordable
gold substitute, while professionals have remained keenly aware
of silver's propensity to outperform in a bull market."
Silver <XAG=> was bid at $34.46 an ounce from $35.25 on
Thursday, having rallied to a 31-year peak above $36 on Monday.
Holdings of iShares Silver Trust <SLV> were unchanged at a
record high at 10,974.06 tonnes.
"We have raised our silver price profile significantly, by
16 percent to $35.50 an ounce in 2011 and 18 percent to $36.25
an ounce in 2012," said BNP Paribas in a report.
"We expect investment demand to remain strong throughout the
year and the gold/silver ratio to stay in the low 40s."
Spot platinum <XPT=> was at $1,761.49 an ounce from
$1,760.24 on Thursday and palladium <XPD=> at $744.97 an ounce
from $765.50 an ounce.
"The appeal of (platinum and palladium) has been tainted by
people worrying about the rise in oil prices and the impact on
economic growth," a trader said.
