NEW YORK, July 13 (Reuters) - U.S. gold futures retreated by midmorning Friday on profit-taking, but a weakening dollar and firmer oil prices limited losses and traders said the yellow metal should rise further in the near term.
"Gold will continue to firm up as long as the dollar is weakening the way it has been," Carlos Perez-Santalla of Hudson River Futures said from the COMEX floor.
At 10:57 a.m. EDT (1457 GMT), most-active gold for August delivery GCQ7 on the COMEX division of the New York Mercantile Exchange was down $2.40 at $665.90 an ounce, trading between $664.40 and $669.90.
Investors opted to lock in profits after this week's rally. August gold on Thursday surged to a peak of $671 which marked the loftiest level since June 7. Gold futures have rallied more than $20 or 3 percent from last Thursday's close of $650.60.
U.S. oil futures rose more than 1 percent to $73.30 per barrel on supply concerns and speculative buying.
The dollar continued to slump and touched a record low against the euro in morning trading. The greenback then retraced some of its early losses.
The dollar is still on pace for its second-biggest weekly drop of the year against a basket of major currencies, the dollar index .DXY, which is down more than 1 pct on the week.
A weaker dollar makes gold cheaper for investors holding other currencies. Meanwhile, gold is seen as a hedge against oil-led inflation.
"I think we are going to see $678 next week..because of the weak dollar," Perez-Santalla said.
"The combination of weak dollar and oil driven inflationary concerns will continue to work in gold's favor," said James Moore, an analyst at TheBullionDesk.com.
Moore said that spot gold's next resistance level was seen at $675 and the precious metal could challenge $690.
Bullion's rise prompted investors to increase holdings in StreetTRACKS Gold Shares GLD.N, the No. 1 gold ETF.
Most recent data showed bullion held by StreetTRACKS XAUEXT-NYS-TT increased to 484.84 tonnes, more than 20 tonnes higher than 464.22 tonnes reported last Thursday. An inflow is a bullish signal because it shows that longer-term investors are entering the bullion market.
Spot gold XAU= was quoted at $664.30/664.90 an ounce, lower than $667.00/667.80 late Thursday. The London afternoon gold fix was $666.50.
