USDA data show Australia's record 13.4 million tonne 2016/17 barley crop will make it the largest barley exporter this season, supplying about a quarter of world demand. Australian barley prices are nearly $30/t lower year over year, and China's imports of Australian barley more than tripled in early 2017 after the China-Australia FTA removed duties.
Abundant low-priced Australian barley is displacing EU and Ukrainian supply and keeps feed grain prices depressed, favouring cheap feed for buyers.
