GB grower held potato stocks at the end of March 2019 are estimated at 0.98Mt, a fall of 26% (353Kt) on last year and 13% (148kt) below the five season average (2013-2018).

Despite a smaller crop this season, stocks remain higher than at the same point in 2012/13 (+162Kt) and are only marginally below stock levels in both 2013/14 (-10Kt) and 2015/16 (-6Kt).

Below average drawdown

The end of March estimate suggests that an additional 0.86Mt of crop was released from grower ownership since our last estimate. This comes in at 13% below the five season average (2013-2018) and is the lowest drawdown since 2012/13.

Packing supplies bolster total stocks

While the overall stock levels stands 13% below both the five and three season averages, individual market sectors continue to show significant differences in drawdown rates. The unique start to the season is a key factor driving this. We previously covered these diverging dynamics when we delved into the end of January figures.

With sector level data available back to 2015, we are able to compare levels over the preceding three seasons (2015-18).

The total stock figure is bolstered by a relatively large quantity of packing supplies ( c.412Kt), which while 17% below stocks at the same period in 2017/18, remains slightly higher than average (2015-18). At this point of the total crop left in grower ownership, 42% is intended for the packing market. This is 6 percentage points higher than average (2015-18) for this point in the season.

Stocks for the fresh bags and chipping market are currently estimated at 153Kt, a 14% reduction from average (2015-18). While stocks are 32% lower year on year, levels remain in line with both 2015/16 (+8Kt) and 2016/17 (-6Kt).

For processing stocks, drawdown has returned closer to normal following increased movement earlier in the year as growers moved at risk stocks. Processing stocks stood at c.316Kt, 12Kt below stocks in 2016/17 another year of tight supply. This comes in at 17% below average (2015-2018) and a 25% reduction on the year.

Scotland continued to account for a large proportion of total stocks at end-March, with 34% (c.334Kt) located within the country. An availability of competitively priced good quality packing material from Scotland has weighed on prices in recent months with material moving well into England. With a significant proportion of stocks still located within Scotland this seems a trend that is likely to continue as the season moves forward.


Despite stocks remaining below average the careful management and relaxing of specifications this season has limited some of the impact from this season’s low production. With the likelihood of significant carryover to be limited to the packing sector, the availability of the early crop will be the key watch point as we approach the new season. At this point, planting is progressing at pace and conditions appear good across the majority of GB. However, water availability remains a concern for some regions moving forward.
