One of the oldest traded spices, ginger is used in everything from biscuits to curry, so manufacturers will be relieved to hear that prices have started to fall sharply from the highs seen over the past two years.

Ginger is sourced largely from Asia, in particular China and India, and to a lesser extent from Africa, where Nigeria is the biggest exporter. On both continents, prices have tumbled, with the most dramatic and sustained falls seen in Asia.

After rising sharply to a high of almost $1,600/tonne at the end of 2010, wholesale prices in China have now plummeted to below $600/tonne [Mintec]. Meanwhile, in Nigeria, the price of dried ginger has almost halved over the past year to about $2,000/tonne, according to independent commodity broker Blair Coutts.

Prices have fallen because farmers were encouraged by high prices in 2010 and 2011 to expand their cultivations, leading to significant over-supply and lower prices.

Falling global commodity prices have started to filter through to the UK market, but stringent requirements on traceability and food safety – which restricts the sources UK buyers can use to buy ginger – mean the prices paid in this country have not fallen as dramatically as might have been expected from the commmodity price.

They certainly haven’t fallen enough to cancel out the retail price increases seen in 2011, report UK manufacturers. “The ginger market was very firm in 2011 and pricing was very high indeed,” says a spokesman for United Biscuits, maker of McVitie’s Gingernuts. “Fortunately the market has weakened slightly in comparison for 2012, although we remain above 2010 levels.”

If commodity prices remain at their current low levels, however, significant savings for UK ginger buyers should soon be on the horizon.

Commodity risers and fallers

Ahead of this Sunday’s Greek elections, oil prices have continued to weaken amid fears about a worsening of the Eurozone crisis. Hopes for a boost from the bailout of Spanish banks were short-lived and crude prices soon started slipping again - at £477.2/tonne, they are now 10.9% cheaper than this time last year, having fallen by a further 13.6% over the past month.

Maize prices have also been slipping, tied as they are to crude through ethanol. There has been some bounce-back following concerns about dry weather in the US, but prices remain 21.7% below June 2011 levels and have fallen by 13% in the past four weeks.

Rice prices have continued to rise, up 10.2% in the past month and 25% year-on-year
