(Updates with New York prices, comment)

LONDON, June 12 (Reuters) - Gold tumbled by more than 2 percent on Thursday to its lowest level since early May as the dollar extended gains against the euro after the release of above consensus data from the United States.
Spot gold <XAU=> fell to $856.80 an ounce, the lowest since May 2, as the dollar rose after data showed U.S. retail sales jumped by 1 percent in May. [
]The news reinforced growing perceptions that U.S. interest rates may have bottomed and that the next move by the U.S. Federal Reserve would be a hike, possibly later this year.
Gold <XAU=> cut declines for a late New York quote at $868.10/870.10 an ounce by 1615 EDT (2115 GMT) from $881.15/882.55 late in New York on Wednesday.
In New York, August gold futures <GCQ8> on COMEX division of New York Mercantile Exchange finished $10.9 lower at $872.0 an ounce, and set a range between $860 and $873 an ounce.
While falling crude prices and rising dollar against the euro hurt U.S. gold futures as well, traders cited gold's bounce off a 200-day moving average for some late technical buying.
Earlier, the benchmark gold contract tumbled to a low dating back to March 2 at $859.6 an ounce.
"The shape of the trendline for gold prices is currently very dependent on the US dollar, although the amplitudes of the swings are relatively low," said Eugen Weinberg, commodities analyst at Commerzbank.
Anti-inflation rhetoric by a Fed official also helped the dollar earlier on Thursday. [
]Gold has see-sawed this week in line with the dollar and crude oil prices.
"We are seeing gold tracking forex ... There is so much uncertainty regarding inflation and where crude oil is going," said Standard Bank analyst Walter de Wet.
FLOOR
Falling crude <CLc1> prices are pressuring gold, which is often bought as a hedge against oil-led inflation. [
]But with prices still firm over $130 a barrel and within reach of the all-time high they set last week, "crude oil definitely provides a floor in gold prices," said de Wet.
Forex, however, remains the main driver. The dollar has taken a firmer tone this week after a raft of comments from U.S. officials expressing concern over the currency's weakness.
U.S. Federal Reserve Chairman Ben Bernanke's increased emphasis on rising inflation has been interpreted as a sign that an interest rate hike may be on the cards later this year.
However, with expectations for a euro zone rate hike also rising, currency markets have been volatile this week, leading to similar fluctuations in gold.
The precious metal benefits from a weaker dollar as it is seen as an alternative investment, while a softer U.S. currency also makes dollar-priced metals such as gold cheaper for holders of other currencies.
"Given the likelihood of further rate speculation/economic data reaction, gold could see further slippage," said TheBullionDesk.com analyst James Moore.
Platinum <XPT=> tracked gold lower, but trimmed losses to $2,010.50/2,030.50 in late in New York versus $2,032.50/2,052.50 on Wednesday.
The white metal has largely moved in tandem with gold as the dollar has fluctuated, but is also benefiting from fears over supply from major producer South Africa.
Platinum therefore "looks likely to outperform gold as dollar strengthens," Fairfax IS analyst John Meyer said.
The republic, which produces around 80 percent of global platinum supply, is suffering from a power shortage that is expected to cut metals output.
Palladium <XPD=> firmed in late New York trade to $435/443 an ounce against 424.00/432.00 an ounce, while silver <XAG=> pulled off earlier lows to still trade lower at $16.45/16.55 from $16.88/16.95 an ounce on Wednesday.
