LONDON, March 18 (Reuters) - Gold pared gains on Friday as Libya's declaration of a ceasefire soothed some financial market jitters and hit oil prices, while investors also looked to an intervention in the yen as a move that could calm markets.
But bullion remained underpinned by market uncertainty as France said it was still cautious about the ceasefire and as Britain prepared warplanes for action. [
]Gold was at $1,418.07 an ounce at 1306 GMT from $1,402.40 late in New York on Thursday. Earlier the metal was little changed after news China's central bank would raise lenders' required reserves by 50 basis points. [
]Muammar Gaddafi's government declared a ceasefire to protect civilians and comply with a United Nations resolution passed overnight, Libyan Foreign Minister Moussa Koussa said.
Gold earlier hit a session high of $1,423.70 an ounce, supported by the United Nation's approval of military action to contain Gaddafi, while unrest in Bahrain has also unnerved investors. [
] [ ]"If that (the ceasefire) actually stands and is sustained, then concerns soften in regard to the wider implications for the whole region," said Carl Firman, an analyst at Virtual Metals.
"If the MENA (Middle East and North Africa) region stabilises ... we'll see confidence return," he added.
A weaker U.S. dollar against a basket of currencies also supported dollar-priced gold.
GLOBAL UNCERTAINTY

"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 as investors sold the metal to cover losses elsewhere.
"When everything turns into risk (aversion) 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."
Curbing investors' flight to gold as a safe haven from inflationary pressures, Brent crude oil prices reversed earlier gains to trade near $114 an ounce after the ceasefire announcement. [
]Inflation watchers also kept an eye on China, where the central bank announced it would raise lenders' required reserves for the third time this year and the sixth since November. [
] [ ]The move increases the required reserve ratio for the country's biggest banks to a record 20.0 percent, another step in the government's campaign to control inflation.
