Wool's eastern market indicator (EMI) has plummeted by 75c/kg, or around 8.9pc, this week.
The EMI closed on Thursday night at 764c/kg clean/kg.
Most of the week's fall came on Tuesday, the first day of selling, when the EMI fell by 62c/kg in just one day's sales in Sydney and Melbourne.
The market steadied on Wednesday, but the EMI still lost another 6c/kg and a further 7c/kg on Thursday.
The northern indicator closed the week on 797c/kg, and the southern indicator on 736c/kg.
The market in Fremantle opened poorly on Wednesday, following the lead set in the east on Tuesday, with the western indicator falling on Wednesday by 53c/kg, to 737c/kg.
On Thursday, Fremantle lost another 8c/kg, closing the week on 729c/kg.
The slide in the wool market comes despite a further fall in the value of the $A.
This normally should have helped lift the Australian market.
The value of the $A had fallen to US66.8c at the close of wool selling on Thursday afternoon.
Growers responded to the market slump this week by passing in 38pc of the wool offered for sale on Tuesday, 33pc on Wednesday and 31pc on Thursday.
Value was wiped from all descriptions of wool, but it was the fine wools that have been the worst hit.
