LONDON, Dec 7 (Reuters) - Arabica coffee futures on ICE were lower on Friday with the market moving back down towards a 2-1/2 year low set earlier this week, weighed by surplus supplies.
Raw sugar futures on ICE also fell as the prospect of a large global surplus in 2012/13 kept the market on the defensive, while cocoa edged up as dealers eyed a widening front month premium in London.
Dealers said the arabica coffee market was struggling to absorb a large Brazilian crop this year while the prospects for next year's harvest in the world's top producer were favourable.
March arabica coffee futures were down 1.55 cents or 1.0 percent at $1.4940 per lb at 1304 GMT, drifting back down towards a two-and-a-half-year low of $1.4635 touched Wednesday.
"I don't see $1.50 (a lb) as the end of the potential slide. There is much more coffee coming to the market and $1.50 is still a level at which you can make a profit in Brazil," F.O. Licht analyst Stefan Uhlenbrock said.
"Historically the market has always fallen back to somewhere between $1.20 and $1.40 which is where Brazilian production costs are seen widely," he added.
Arabica coffee prices have been cut in half during the last 18 months with increasing supplies helping to dampen investor appetite for the commodity.
Slow sales by Brazilian producers had helped to underpin the market but could soon turn into a bearish factor with much coffee remaining unsold, dealers said.
Brazil is likely to ship about 5 million fewer bags of green, unroasted coffee this year than in 2011, even though a larger crop was gathered this year, the Council of Green Coffee Exporters said on Thursday, citing slower sales and weather-related delays.
"There is a lot of coffee in the hands of Brazilian producers which still has to find a home," Uhlenbrock said.
March robusta coffee on Liffe fell $26 or 1.4 percent to $1,885 a tonne.
WIDENING SUGAR SURPLUS
Raw sugar futures on ICE were also lower with the market also weighed down by excess supplies.
Consultancy Kingsman SA revised up its 2012/13 world sugar surplus estimate to 9.2 million tonnes raw value on Friday, citing increased supply from producers including Brazil and China.
March raw sugar on ICE was off 0.10 or 0.5 percent at 19.26 cents a lb.
"We seem to be range bound 20/30 points either side of 19.50 in the short term but we feel there is more potential downside than upside," Thomas Kujawa of Sucden Financial said in a note.
"We feel it's safer to sell a rally than buy a dip and we expect lower levels in the medium term," he added.
March white sugar on Liffe was off $2.80 or 0.5 percent at $515.70 per tonne.
Cocoa futures were marginally higher with the focus on the recent widening of the front month spread in London <LCC-1=R>.
The premium was trading around 75 pounds on Friday after peaking at more than 80 pounds during the previous session as the open position on December was still well in excess of certified stocks just a few days before Wednesday's expiry.
"If you don't have tenderable cocoa then you already should have focused on the March position," said a European trader.
"If your short is on the December and your cocoa is not tenderable then you have a little bit of a problem. If you start sampling today I don't think you'll get grading sorted out before Wednesday, you could be lucky, but don't count on it."
March cocoa on Liffe rose 3 pounds or 0.2 percent to 1,550 pounds a tonne while March cocoa on ICE stood $5 or 0.2 percent higher at $2,425 a tonne.
