LONDON, June 6 (Reuters) - Raw sugar and arabica coffee futures on ICE rose slightly on Wednesday, trading above 22-month lows earlier in the week, as a weak dollar supported dollar-priced commodities, while investors awaited the results of a European Central Bank meeting. Cocoa futures on Liffe were higher after ICE cocoa moved higher on Monday and Tuesday, when London markets were closed. The European Central Bank is due to announce the outcome of its latest policy meeting at 1245 GMT, with the market consensus calling for it to keep interest rates unchanged at 1 percent. SUGAR * Raw sugar futures hovered above Monday's 22-month low, supported by demand on the physical market ahead of the Muslim fasting month of Ramadan. * ICE July sugar futures were up 0.35 cent or 1.8 percent at 19.41 cents a lb at 0851 GMT after touching 18.86 cents earlier in the week, the lowest level for the front month since August 2010. * Sugar output from Mauritius is expected to fall 5.8 percent to 410,000 tonnes this year from 435,309 tonnes in 2011 due to lower rainfall, the Chamber of Agriculture said on Tuesday. * India's annual monsoon rains have arrived at the southern Kerala coast, a top weather official said on Tuesday, brightening prospects for higher farm output by helping farmers plant summer-sown crops such as rice, soybean and cotton on time. * New York July sugar will retest a support at 18.88 cents per lb, a break below which would trigger a further loss to 18.65 cents, according to Reuters analyst Wang Tao. * London August white sugar was up $4.40 or 0.8 percent at $557.90 per tonne. COFFEE * Arabica coffee futures were higher, above Monday's 22-month low, with dealers anticipating a rise after the market had become oversold. * Arabica coffee prices have fallen by around 30 percent since the beginning of the year, while robusta coffee has risen around 15 percent over the same period, in part due to roasters' switching out of more expensive arabicas into robustas. * July arabica on ICE was up 1.55 cent at $1.5775 per lb. September was up 1.45 cent at $1.5990 after the second month touched $1.57 on Monday, the lowest price for the second month since July 2010. * A bearish target at $1.5270 per lb remains unchanged for New York July coffee as indicated by its wave pattern and a Fibonacci projection analysis, according to Reuters market analyst Wang Tao. * Robusta futures on Liffe were slightly higher, with September up $10 or 0.5 percent at $2,153 a tonne. * Indonesian coffee production will grow by 17 percent to 9.7 million 60-kg bags green bean equivalent in marketing year 2012/2013 due to more supportive weather conditions, according to a U.S. Department of Agriculture attache. COCOA * Liffe cocoa futures were higher, tracking gains made earlier in the week on the ICE market while London was closed. * Dealers said news that Ivory Coast new crop forward sales were ahead of levels some had expected had been bullish for prices. * Ivory Coast sold 620,000 to 640,000 tonnes of its 2012/2013 cocoa harvest by May 20 as part of a system of auctions introduced earlier this year, an official in the finance ministry said on Monday. * Liffe September cocoa futures traded up 40 pounds or 2.8 percent at 1,491 pounds a tonne, while ICE July cocoa futures fell $19 or 0.9 percent to $2,144 a tonne. * Official cocoa purchases in Ghana reached 775,761 tonnes by May 24 since the start of the season in October, down 11.3 percent from the 874,291 tonnes recorded in the same period a year ago, according to data from regulator Cocobod seen by Reuters on Tuesday. * Cocoa farmgate prices in Ivory Coast's principal growing regions declined last week as falling prices on the futures market sapped export demand, farmers and buyers said on Tuesday. * New York July cocoa will extend its Tuesday gain to $2,189 per tonne, as indicated by its wave pattern and a Fibonacci retracement analysis, according to Reuters market analyst Wang Tao. OTHER MARKETS * European shares and the euro gained on Wednesday as the acute financial problems in Spain and recent data confirming a widespread economic slowdown across Europe fueled hopes that the region's central bank would respond with stimulus measures. * Oil rose toward $100 a barrel on Wednesday as supportive economic and crude stocks data from the United States outweighed pressure from Europe's lingering debt crisis. * The euro rose on Wednesday as investors cut hefty short positions, though concerns about Spain's troubled fiscal situation and the possibility of a rate cut by the European Central Bank could limit its rise.
