NEW YORK, Aug 18 (Reuters) - Gold rose to a 1-1/2 month high on Wednesday, extending a rally to a fifth day on strong physical demand and as the dollar's initial losses triggered technical buying.
The metal has risen nearly 3 percent in the last five sessions, the biggest five-day percentage rise since May.
Silver and platinum group metals stayed lower on broad weakness in commodities and a decline in crude oil.
Bullion benefited from a weaker dollar against major currencies. Earlier this week, however, gold rose on safe-haven buying along with U.S. Treasuries.
"It's still a safe-haven mentality as people are not satisfied with the fiat currencies. They see the $1,220 level as a possible bargain as we get closer to the Indian wedding season and there was physical buying overnight," said Michael Daly, gold specialist at Chicago-based futures broker PFGBest.
Physical gold demand tends to rise in August as jewelers stockpile inventory ahead of the start of top consumer India's wedding season. The country's busy festival season starts with Raksha Bandhan on Aug. 24 and extends until Dhanteras in November, the single biggest gold-buying day.
Spot gold <XAU=> was at $1,229.15 per ounce by 3:22 p.m. EDT (1922 GMT), up from $1,222.90 late in New York on Tuesday. U.S. gold futures for December delivery <GCZ0> settled up $3.10 at $1,231.40 per ounce.
Turnover in COMEX gold remained quiet in the summer months, near a one-year low set on Tuesday, preliminary Reuters data showed.
However, silver futures volume spiked to more than 70,000 lots, their highest level in nearly two months, due to heavy profit-taking in an overbought market, traders said.
Gold moved higher as the dollar fell sharply against a basket of major currencies <.DXY> in earlier trade, resuming its usual inverse correlation with the U.S. currency that reappeared recently. The dollar index traded flat in later sessions.
Gold is strengthening its inverse correlation relationship with the dollar and a positive link with the euro, analysts said.
The 25-day simple correlation between gold and the dollar fell to a plus 0.1 on Monday, sharply lower than a high of over plus 0.8 earlier in August.
After trading in a broad range for two months, gold has rallied this week on worries about a double-dip recession after a flurry of weak economic data and the Federal Reserve's downgrade of its economic outlook.
On charts, gold is poised to challenge its all-time high at $1,264.90 an ounce set on June 21, after the metal held above $1,160 an ounce back in late July.
FUNDS BUY OPTIONS
COMEX floor trader Jonathan Jossen said gold futures' rise was "purely technical" as prices began to rally after the metal found support at $1,223 an ounce, where a series of successive highs were made back in mid-July.
Strong fund buying also suggested gold could have a sharp move in the near term, Jossen said.
"There are a lot of big options trade, and the funds are getting back in. The funds will put their bets on when they think technically it is going to make a move," Jossen said.
U.S. stocks also rose as advancing consumer shares helped push the S&P 500 into positive territory, while crude oil fell to a five-week low as government data showed crude inventories and oil products rose to record highs. [
