Tuesday’s Global Dairy Trade (GDT) event saw the price index fall 4.7% - the largest single event index drop since October 2022.
Anhydrous milk fat slipped the most of any commodity traded, falling 7.2%.
Whole milk powder followed with a 5.2% price cut, while butter and butter milk powder were both back 3.3%.
Cheddar was the only dairy commodity to have any bounce on the previous event.
However, cheddar took a tumble of over 10% at the event two weeks ago.
The 4 April event represents the sixth time the GDT dropped this year out of seven trading dates.
