Just because a document shows a certain bank balance amount on a certain date doesn't mean the funds are unencumbered/free and clear.
An audit, which Tether refuses to provide and which companies large and small undertake on a regular basis, would answer that question.... Additionally, assuming, arguendo, that Tether is backed 1:1 (which I otherwise do not), that much cash sitting in a bank should trade not at par but at a discount commensurate with the credit rating of the bank.
