This is a case of JPMorgan Chase (Holder of relevant interest) borrowing from registered holders (JPM Nominees Australia Pty / Limited, Citi Australia, Ecapital Nominees Pty/Ltd), then lending for others to short. JPM Australia was also doing some buying and selling. No collusion to see there...
From top twenty list of registered holders....
The lending contracts were with JP Morgan Chase lending to several brokers (Macquarie Bank, Merrill Lynch, Morgan Stanley, UBS) who could then either short or lend to others (such as hedge funds).
JP Morgan Securities PLC also had master agreements to borrow frm other lenders such as Black Rock, Citibank N.A., CALIFORNIA STATE TEACHERS' RETIREMENT SYSTEM, The Northern Trust Company, State St Bank and Trust Company, The Bank of New York Mellon Corporation.
So a complicated cascade / web of lending from large holders via Morgans to banks for shorting.
