NEW YORK/LONDON, July 30 (Reuters) - Gold fell 1 percent on Thursday to a near a 5-1/2-year low as the dollar rose after data showed the U.S. economy improved in the second quarter, supporting views that the Federal Reserve would lift rates by year-end.
The U.S. Department of Commerce said gross domestic product expanded at a 2.3 percent annual rate. First-quarter GDP, previously reported to have shrunk at a 0.2 percent pace, was revised up to show a 0.6 percent rise. ID:nLNNUIEBDP
Spot gold XAU= dropped as much as 1.3 percent to a session low of $1,081.85 an ounce in earlier trading, not far from its cheapest since February 2010 at $1,077 hit after a selloff on July 20. It was down 0.7 percent at $1,089.11 by 2:07 p.m. EDT (1807 GMT).
With the stronger dollar and the likelihood of a rate hike by the end of the year, "there's no need for any kind of safety whatsoever," said Phillip Streible, senior commodities broker for RJO Futures in Chicago.

That buoyed the dollar, which was up 0.4 percent against a basket of leading currencies, making dollar-priced gold more costly for non-U.S. buyers.
U.S. gold for August delivery GCcv1 slipped 0.4 percent to settle at $1,088.40 an ounce.
"As the focus is back on the dollar and its strength, the trajectory for gold is down until a hike actually happens," Citigroup (NYSE:C) strategist David Wilson said.
Mizuho Bank said in a note that it expected just one rate increase this year, with the Fed adopting a gradual pace of tightening. "And policy will continue to be conditioned on data," it added.
Holdings of the largest gold-backed exchange-traded fund, New York's SPDR Gold Trust GLD , were unchanged at 21.87 million ounces for a second day on Wednesday. That level is the lowest since September 2008. GOL/ETF
Spot platinum XPT= was up 0.1 percent at $983.24 an ounce, within reach of a 6-1/2-year low of $942.49 hit in the previous week. Palladium XPD= was up 0.2 percent at $617.25 an ounce, and silver XAG= dropped 0.1 percent to $14.72 an ounce.
