NEW YORK, Aug 16 (Reuters) - Gold rose nearly 1 percent on

Thursday as comments by German Chancellor Angela Merkel and

disappointing U.S. manufacturing and housing data fueled

speculation that central banks may be set to launch more

bullion-friendly stimulus measures.

Platinum rose 3 percent as supply worries in South Africa

prompted investors to buy the metal. Labor unrest forced Lonmin

, one of the world's top platinum producers, to

cease production. South Africa accounts for three-quarters of

the world's platinum output.

Gold posted its biggest one-day gain in two weeks after

Merkel voiced support for European Central Bank President Mario

Draghi's crisis-fighting strategy. Data showing

contracting manufacturing activity in the U.S. mid-Atlantic

region and slow housing starts also raised hopes for Federal

Reserve stimulus.

Open interest, a liquidity gauge that measures the number of

outstanding long and short contracts, fell to a 2012 low for

U.S. gold futures on Wednesday, latest exchange data showed.

Doubts about central banks' commitment to take aggressive steps

to boost their economies have kept gold prices in a trading

range in the last four months.

"The open interest in gold is indicating rallies are mainly

short-covering now. Also, the upcoming Jackson Hole conference

with (Fed Chairman Ben) Bernanke hopefully discussing a stimulus

of some kind moved traders," said George Gero, vice president of

RBC Capital Markets.

Most Wall Street economists still expect the Federal Reserve

to do more to stimulate growth this year, with the majority

looking for action as soon as September after an annual meeting

of economists and central bankers in Jackson Hole, Wyoming, on

Aug. 31.

Spot gold gained 0.8 percent to $1,616.20 an ounce by

2:09 p.m. (1809 GMT).

U.S. COMEX gold futures for December delivery settled

up $12.60 at $1,619.20 an ounce, with trading volume about 30

percent below its 30-day average, preliminary Reuters data

showed.

Tame U.S. inflation data on Wednesday reassured investors

that price pressures would not prevent the Fed from launching

more quantitative easing - printing money to buy bonds in a bid

to keep interest rates low - if a more negative view of growth

emerges.

"My general view is that for the time being, major central

banks will let go of the mandate of price stability in favor of

spurring growth figures," LGT Capital Management analyst Bayram

Dincer said.

PHYSICAL DEMAND SOFT IN 2ND QUARTER

A closely watched report from the World Gold Council showed

on Thursday that demand for physical gold from jewelers and

investors fell in the second quarter to its lowest level since

the first three months of 2010.

Among other precious metals, silver was up 1.5

percent at $28.21 an ounce, while spot platinum was up

3.4 percent at $1,436.49 an ounce. Spot palladium was up

0.7 percent at $587.47 an ounce.

Lonmin, the world's No. 3 platinum miner, said that so far

it has lost 15,000 ounces of platinum production due to labor

unrest. South African riot police opened fire on striking miners

Thursday, killing at least a dozen men in the deadliest episode

of a week of union violence.
