ROME (REUTERS) - World food prices dipped in May for a second consecutive month after hitting a record high in March, although the cost of cereals and meat both rose, the United Nations' food agency said on Friday (June 3).

The Food and Agriculture Organisation's (FAO) food price index, which tracks the most globally traded food commodities, averaged 157.4 points last month versus 158.3 for April. The April figure was previously put at 158.5.

Despite the monthly decline, the May index was still 22.8 per cent higher than a year earlier, pushed up in part by concerns over the impact of the Russian invasion of Ukraine.

In separate cereal supply and demand estimates, the FAO said it expected global cereal production would drop in the 2022/23 season for the first time in four years, easing 16 million tonnes from record 2021 levels to 2.784 billion tonnes.

While the dairy, sugar and vegetable oil price indices all fell last month, the meat index edged up to hit an all-time high, and the cereal index climbed 2.2 per cent, with wheat posting a 5.6 per cent month-on-month gain.

Year-on-year, wheat prices were up 56.2 per cent.

The FAO said wheat prices were shunted higher by India's announcement of an export ban, as well as reduced production prospects in Ukraine following the Russian invasion.

The vegetable oil price index dropped 3.5 per cent from April, pushed down in part by Indonesia's decision to lift a short-lived export ban on palm oil.

"Export restrictions create market uncertainty and can result in price spikes and increased price volatility. The decrease in oilseeds prices shows how important it is when they are removed and let exports flow smoothly," said FAO chief economist Maximo Torero Cullen.

The dairy index also dropped by 3.5 per cent month-on-month, with the price of milk powders shedding the most because of market uncertainties tied to continued COVID-19 lockdowns in China.

The meat index rose 0.6 per cent in May, with stable world bovine meat prices and falling pig meat prices offset by a steep increase in poultry prices.

Issuing its first forecast for global cereal production, the FAO predicted declines for maize, wheat and rice production, while barley and sorghum outputs were seen increasing.

"The forecasts are based on conditions of crops already in the ground and planting intentions for those yet to be sown," the FAO said.

World cereal utilisation was forecast to ease in 2022/23 by 0.1 per cent from 2021/22 levels, to 2.788 billion tonnes - the first contraction in 20 years.
