NEW YORK, April 29 (Reuters) - Gold surged nearly 2 percent to a record for a third consecutive day on Friday, as inflation worries, a dollar drop and expectations the U.S. Federal Reserve will maintain loose monetary policy lifted bullion to its biggest one-day gain in two months.
In late U.S. afternoon trade, bullion sharply extended early gains, as U.S. consumer spending rose for a ninth straight month in March with inflation at its highest in nearly a year. Platinum group metals also rose about 2 percent but silver fell 1 percent after soaring to record high in the previous session.
Option traders reported strong buying of call options and call spreads, reflecting bullish market expectations. A gauge of bullion market volatility also spiked in response to a sharp price rally.
"What has been driving gold is an abundance of liquidity of Fed policy that remains exceedingly accommodative, which is going to work against the U.S. dollar," said Mark Luschini, chief investment strategist of broker-dealer Janney Montgomery Scott, which manages $53 billion in client assets.
"There is worry that inflation, which is not a problem right now, could escalate to become one. And once it does, it becomes very difficult to put the genie back into the bottle," he said.
Spot gold <XAU=> was last up 1.8 percent at $1,562.60 an ounce by 3:40 p.m. EDT (1940 GMT), having earlier hit an all-time high $1,569.30. The metal notched a 9 percent monthly gain, its strongest since November. Bullion also posted its seventh consecutive weekly rise, its longest winning streak since 2007.
U.S. June futures <GCM1> settled up 1.7 percent at $1,556.40 an ounce, with trading volumes about one-third below its 30-day average due to a public holiday in London.
On the options front, heavy buying of outright call options and bull call spreads of June 2012 calls with strikes $1,800 and $2,000, said COMEX gold options floor trader Jonathan Jossen.
Bull call spread is an option play involving the buying of calls at one strike price while selling them at a higher strike with the same expiration date. Investors often expect prices to rise moderately with the strategy.
Also, the CBOE gold volatility index <.GVX>, which measures bullion investor anxiety, rose 6 percent and set to be one of the biggest daily rise in 2011.
A slight drop in the dollar also contributed to bullion's gains. Earlier in the week, expectations of further weakness in the dollar were the biggest drive for gold and silver rallies to records. [
]Investors look forward to next Friday's nonfarm payrolls data for trading cues, after data this week painted a picture of an economy with slower growth and higher inflation, and after the Federal Reserve signaled it would not tighten monetary policy any time soon.
SILVER RETREATS FROM RECORD
Silver extended gains after it on Thursday eclipsed the peak set in 1980 when Texas brothers William Herbert and Nelson Bunker Hunt attempted to corner to market. It posted a near 27 percent rise in April, its biggest monthly gain since April 1987.
Silver <XAG=> was last down 0.8 percent at $48.03 an ounce.
Silver gained 3 percent this week, although analysts say its robust performance against the other precious metals may not be sustainable.
"If silver doesn't make a new high and sustain above that, it may go through a more vicious correction here. So, gold in the short term could go down in sympathy of that," said James Dailey, portfolio manager of the TEAM Asset Strategy Fund. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

]For platinum group metals, platinum <XPT=> echoed the strength in gold, rising 1.9 percent on the day to $1,870.49 an ounce, while palladium <XPD=> rose 2.6 percent to $790.97. Prices at 3:40 p.m. EDT (1939 GMT)
