Since the start of 2016, the average weekly potato prices have been rising by about £20/tonne. The rising prices are causing farmers to keep hold of potato supplies, further tightening the market. For the week to March 11, average prices were £172.94/t and the GB weekly free buy average was £171.81/t.
The prices are a contrast to the start of last year when free buy values were well below £100/t.
"There are a number of things affecting the market," said Arthur Marshall, from AHDB Potatoes, "There are reports growers are reluctant to sell and open the stores."
Low stock levels
Mr Marshall said this factor was compounding already low stock levels. Figures for the end of January showed the lowest level since the 2012-13 season.
"It comes back to the start of this season. [Last season] there were record yields but area was 8 per cent down," Mr Marshall added.
Focus on quality
Discussing the outlook going forward, Mr Marshall suggested there may be a focus on quality.
"We have mixed reports about quality in-store and that could affect the amount the market lifts. We are getting the sense some buyers are prepared to accept a lesser quality supply."
