From WATTAgNet:

Global food prices in May were at their lowest level since September 2009, according to the United Nations’ Food and Agriculture Organization. Decreases in cereals, dairy and meat products outweighed slight increases in oils and sugar.

By the numbers:

• The Food Price Index averaged 166.8 points in May, down 2.4 points from April and as much as 43.6 points below the same month last year.
• The FAO Cereal Price Index averaged 160.8 points in May, 6.4 points less than in April and 46 points below its level in May 2014. Ample stocks combined with generally favorable crop outlooks for this year continued to keep international prices under downward pressure. Subdued trade prospects, with many importing countries postponing purchases to later this year, also contributed to the general decline in prices. The May average was the lowest since July 2010.
• The FAO Vegetable Oil Price Index averaged 154.1 points in May, up 3.9 points from April, although still 41 points below the same month last year. The gain has been driven by rising quotations for palm and soy oils. Palm oil prices strengthened mainly on account of increased concerns about possible El Niño developments which could affect production in Southeast Asia, while soy oil values firmed primarily on resumed import demand – by China in particular. Quotations for sunflower and rapeseed oil also moved up, reflecting lower than anticipated world production and export supplies.
• The FAO Dairy Price Index averaged 167.5 points in May, down 5 points from April. Milk powders and butter were the main commodities affected, while cheese remained stable. The lingering low prices characterizing world markets reflects large unsold stocks in New Zealand and the buildup of export supplies in Europe, as production in the northern-hemisphere reaches its seasonal peak. Uncertainty over the level of China’s purchases of milk powder during 2015 continues to weigh on the market, although lower prices have stimulated buyer interest in the Middle East and North Africa.
• The FAO Meat Price Index averaged 171 points in May, down 1.7 points from its revised April value. Generally lower prices for meat exports from the United States continue to weigh on the Index. Overall, international prices of bovine and ovine meat moved lower, while those of poultry and pig meat were little changed. In the case of poultry meat, import restrictions imposed by some countries due to outbreaks of highly infectious avian influenza in some states in the U.S. also influenced prices. After declining since June 2014, pig meat prices were relatively stable in April and May, with European prices in particular stabilizing.
• The FAO Sugar Price Index averaged 189.3 points in May, up 3.7 points from April 2015. The increase in May, which represents the first significant rebound since last October, was mainly due to a slow start of the crushing season in Center/South Brazil, as raw sugar prices remain under the pressure of large supplies and growing surpluses in 2014-15.
