Dutch onion prices gain support as drought limits harvest potential

Dry weather changes the supply outlook

The Dutch onion market is showing firmer price signals as drought reduces harvest potential across key growing regions. Machiel Boons, broker at Uienradar, told FreshPlaza that the market environment has changed markedly since his mid-April assessment, when he saw few immediate positive factors but expected conditions could look different four months later.

The most serious drought effects are in the southwest of the Netherlands, although northern production areas are also feeling the pressure. The north avoided the extreme temperatures recorded at the beginning of summer, but rainfall remained limited and growing conditions during the latest month were unfavorable. Boons described the resulting market as stagnant, particularly in week 32, though prices have since begun to rise slightly from week to week and trading activity is increasing.

Short-term availability may still expand. Numerous lots in the southeast were due to be harvested within days of the market update, bringing additional onions onto the market. This supply could temporarily moderate price gains, but it does not remove concerns about national yields and the volume suitable for storage and export later in the season.

Disease adds uncertainty to marketable volumes

Crop quality is another source of risk. According to Boons, buyers have reported a considerable number of lots affected by Fusarium and bacterial rot. He noted that problems appearing in crops grown for seed production can later emerge in onion sets, although he is not directly involved in the onion seed market.

High temperatures and extensive irrigation may also have influenced disease pressure. The combination requires monitoring because losses from rot can reduce marketable supply even where field yields initially appear adequate. For processors and exporters, quality problems also affect storage performance, sorting losses and the amount of product capable of meeting customer specifications.

Boons said a reasonable volume had traded below €0.25. Speculators were the first buyers, followed by processors purchasing onions at the same level. The figure has emerged as a psychological threshold: when prices move above it, more sellers are willing to release stocks. Trading intensity is therefore rising, but the market has not yet established a durable price range.

Exports will determine how far prices can rise

FreshPlaza reported that Boons sees solid grounds for onions to become expensive this season, in contrast with the price-rise expectations heard almost every year. He did not provide a long-term price forecast. The central question is where growers and processors, as well as exporters and their customers, can agree. The Netherlands depends heavily on onion exports, meaning domestic supply constraints can support prices only while foreign buyers continue to regard the level as acceptable.

Boons compared current conditions with 2018, when an exceptional market was already apparent as he entered his second year as an onion broker. He said the present climate is even drier and described it as the warmest year of the past five. However, he expects national yields to be better than in 2018 because irrigation is now more widespread and production is less concentrated in areas where irrigation is impossible.

Even with that improvement, Boons does not expect record crops in the Netherlands, and he said the same applies to much of Europe. That combination gives the market a firmer supply foundation than in an ordinary season. The eventual price increase will depend on harvested volumes, disease-related losses and whether export customers remain active as Dutch quotations rise.
