LONDON, March 18 (Reuters) - Gold rose 1 percent on Friday, as the United Nations authorisation of military attacks in Libya boosted gold's status as a shelter from risk, while investors eyed whether intervention in the yen could calm markets jitters.
Gold hit a session high of $1,416.80 an ounce, trading at $1,415.00 at 1059 GMT from $1,402.40 late in New York on Thursday. The metal was little moved by news China's central bank would raise lenders' required reserves by 50 basis points. [
]Bolstering bullion, the U.N. approved military action to contain Libyan leader Muammar Gaddafi, heightening geopolitical tensions in the oil-rich region and lifting crude prices, while unrest in Bahrain also unnerved investors. [

"The uncertainty across the different global centres is still there and that should support precious metals," said Saxo Bank analyst Ole Hansen.
In the wake of the crisis, Japan bought billions of dollars to restrain a soaring yen and traders reported intervention by European central banks, kicking off joint action by the world's richest nations to calm markets. [
]In recent sessions risk aversion mounted to such heights that even gold, traditionally a safe haven from risk, was no exception to the broad sell-off from risk as investors sold the metal to cover losses elsewhere.
"When everything turns into risk adversity mode no one stays clear of that and the same thing happened for precious metals," Hansen said.
But potential stability in the yen may soothe investors.
"The yen probably holds the key now," Hansen added. "If they manage to keep the yen at these levels that could help stabilise the markets in general and also gold."
CHINA MOVE
China's central bank announced it would raise lenders' required reserves for the third time this year and the sixth since November. [

Meanwhile, investors also sought shelter in gold as a haven from inflationary pressures as Libya's crisis kept oil prices strong. [
]"Military action's always a concerning event for investors," Mitsubishi precious metals analyst Matthew Turner said of the U.N. vote on Libya.
Brent crude <LCOc1> was up 0.5 percent, paring earlier gains after China raised reserve rate requirements.
