World food prices rose for a second consecutive month in September to reach a 10-year peak, driven by gains for cereals and vegetable oils, the United Nations food agency said on Thursday.

The Rome-based Food and Agriculture Organisation (FAO) also projected record global cereal production in 2021, but said this would be outpaced by forecast consumption.

The FAO's food price index, which tracks international prices of the most globally traded food commodities, averaged 130 points last month, the highest reading since September 2011, according to the agency's data.

The figure compared with a revised 128.5 for August. The August figure was previously given as 127.4.

On a year-on-year basis, prices were up 32.8 per cent in September.

Agricultural commodity prices have risen steeply in the past year, fuelled by harvest setbacks and Chinese demand.

The FAO's cereal price index rose by two per cent in September from the previous month. That was led by a near four per cent increase for wheat prices, with the UN agency citing tightening export availabilities amid strong demand.

"Among major cereals, wheat will be the focus in the coming weeks as demand needs to be tested against fast-rising prices,” FAO Senior Economist Abdolreza Abbassian said in a statement.

World vegetable oil prices were up 1.7pc in the month, showing a year-on-year rise of about 60pc, as palm oil prices climbed on robust import demand and concerns over labour shortages in Malaysia, the FAO said.

Palm oil futures have rallied further in early October to hit record highs as a surge in crude oil markets has lent further support to vegetable oils used in biodiesel.

Global sugar prices rose 0.5pc in September with concern over adverse crop weather in top exporter Brazil partly offset by slowing import demand and a favourable production outlook in India and Thailand, according to the FAO.

For cereal production, the FAO projected a record world crop of 2.8 billion tonnes in 2021, up slightly from 2.78bn estimated a month ago.

That would be below world cereal use of 2.81bn tonnes, a forecast revised up by 2.7 million tonnes from a month earlier mainly to reflect increased wheat use in animal feed, the FAO said in a cereal supply and demand note.

Global cereal stocks were expected to ease in 2021/22 but would still be at a comfortable level, the FAO added.
