NEW YORK/LONDON, Dec 19 (Reuters) - ICE raw sugar jumped on Thursday, recovering from the previous day's 3-1/2 year low as a technically oversold condition drove buying, and Liffe robusta coffee fell on expectations of renewed supply movement in top grower Vietnam.
Cocoa futures advanced, as the U.S. Federal Reserve provided support and sent stock markets higher with its plan to start scaling back its bond-buying stimulus.
European shares rallied after the Fed accompanied its decision with a promise to keep record low interest rates in place even longer than previously signalled.
ICE March raw sugar futures rallied 0.27 cent, or 1.7 percent, to 16.16 cents a lb by 12:34 p.m. EST (1734 GMT) as sharply oversold conditions and low prices drove buying.
The front-month sank to 15.86 cents on Wednesday, the lowest level since July 2010, and its 14-day relative strength index fell to the lowest level since 1982.
"You're seeing a mix of end-user buying down here, short-covering, and the macro funds might be bottom-picking," said Nick Gentile, senior partner of commodity trading consultancy Atlantic Capital Advisors.
Further, Indonesia's demand for raw sugar could help absorb excess supply in the global market as No. 2 producer India moves to aid the country's struggling millers.
India's cabinet will consider interest-free loans to sugar mills to help them pay government-set rates to cane growers at a time when sugar prices have fallen, a move that would support production in the face of falling global prices.
March white sugar on Liffe rose $5.30 cents, or 1.2 percent, to $438.70 per tonne, after dipping to $432.10 on Wednesday, the lowest level for the front month since May 2010.
The whites-over-raws sugar premium, a measure of refining profitability, has been subdued for months but looks set to rebound as buyers take advantage of multi-year price lows.
ROBUSTA COFFEE SLIDES
Liffe March robusta coffee eased $15, or 0.9 percent, to finish at $1,684 a tonne, on expectations of supply movement in Vietnam.
Robusta beans in the top grower changed hands below London futures this week for the first time since February.
Robusta prices are expected to slide after being one of the best performing commodities in recent weeks, analysts said. The recent price recovery came as growers held back supplies of a bumper crop.
"We're seeing cash coffee trading at a discount to the exchange, an indication of supplies moving," said Sterling Smith, a futures specialist with Citigroup in Chicago.
Dealers said arabica coffee prices had derived support from the strength of the robusta market and now appeared overvalued given more than ample supplies and the prospect of a huge crop in top producer Brazil next year.
March arabica futures on ICE slipped 0.65 cent, or 0.6 percent, to $1.1530 per lb.
In cocoa, May futures on Liffe finished up 5 pounds, or 0.3 percent, at 1,766 pounds a tonne, entrenched inside its the range of 1,711 pounds to 1,788 pounds in which it has traded for over a month.
The London market was in backwardation, meaning nearby contracts traded at premiums to later dated contracts, indicating expectations of tightening supply.
ICE March cocoa rose $21, or 0.8 percent, to settle at $2,791 a tonne.
Deficit concerns have underpinned prices, even as the recent high port arrivals in top grower Ivory Coast, a sign of supply flow, have kept a lid on further gains.
