LONDON, Feb 22 (Reuters) - Gold edged lower on Monday after hitting a one-month high earlier, as risk appetite eased off and the dollar hit a session high against the euro amid renewed worries about Greek debt.
"We had a dip in the oil price, also in base metals, the dollar is a bit stronger and in equity markets, we've seen a trend lower," said Tobias Merath, analyst at Credit Suisse.
"A lot of fincancial market participants are long so there's still profit to be taken. Also there's concerns about March - its usually the worst time of year for gold."
Spot gold <XAU=> was quoted at $1,115.00 by 1539 GMT, up from $1,117.50 at New York's notional close on Friday, having hit an intraday high of $1,130.65 an ounce earlier.
The dollar came off earlier lows versus the euro to hit a session high amid reports Germany has made no decision on aid for Greece. [
] [ ]A stronger dollar weighs on gold as it dents the metals appeal as an alternative to the U.S. currency. It also makes dollar-priced gold costlier for non-U.S. investors.
Also weighing on gold, U.S. stocks fell on Monday as markets continue to assess the implications of the Federal Reserve's move to increase emergency borrowing rates for banks and Greece's debt issues remain unresolved. [
]Gold, sometimes bought as a safe haven asset and hedge against financial uncertainty, has been moving in line with risk appetite in recent weeks.
Currency markets took the Fed's surprise decision to raise its discount rate last week as a signal the U.S. central bank was coming closer to raising its benchmark rate.
Although a benign U.S. inflation reading on Friday caused markets to reassess that view, there remains underlying nervousness with regards to U.S. monetary policy.
VOLATILE
Investors await Fed Chairman Ben Bernanke's twice-yearly testimony to Congress and the Senate on Wednesday and Thursday for further clues on rate policy, and also further clues on the U.S. economy. [
]"Markets are set to remain volatile in the week ahead due to the line-up of economic data and in particular Friday's GDP reading as players look for sign of continued growth as the Fed begins to reign in its emergency measures," said James Moore, analyst at TheBullionDesk.com
Bullion was about 8 percent below a lifetime high above $1,200 an ounce struck in early December and but still well above a three-month low around $1,043 hit almost three weeks ago.
U.S. gold futures for April delivery <GCJ0> fell $6.7 an ounce to $1,115.50 an ounce, after hitting an intraday high of $1,131.50 on Monday, the strongest in a month.
Gold priced in euros <XAUEUR=R> traded at 819.30 euros, off last week's record of around 830 euros.
Oil held just below $80 a barrel on Monday, paring much of an earlier gain to a six-week high and denting the appeal of gold as a hedge against oil-led inflation. [
]In other precious metals, silver <XAG=> was at $16.25 an ounce versus $16.27, platinum <XPT=> was at $1,527.00 versus $1,530 and palladium <XPD=> was at $437.50 versus $437.00. (Reporting by Maytaal Angel; Editing by Michael Urquhart)
