Prolonged dryness has been adversely affecting wheat crops in the UK, northern Europe and the Black Sea region. This has helped support world wheat prices in recent weeks. This week, however, saw a change to weather patterns as low pressure systems sweeping in from the west brought much needed rain and relief to stressed winter and spring wheat fields. Confidence that notable yield losses may have been avoided triggered a wave of selling on futures markets. Buyers stood aside and prices dropped to eight-week lows. It remains to be seen how beneficial this rain has been.
