2 Billion is nothing to Chase, Deutche, Sumitomo, Nakamora, Bank of England, Tiaa/Cref...and many others.
My father and his friends were CFOs and CEOs for private held Family fortunes that were in the 10 and 11 digits ranges, money that makes Trump look like the Chump he is.
And they deal not hundreds of Banks...Usually its 3 or 4....
For Instance Sterling National in NY only had 2 branches till 20 years ago, now they have 5 maybe.
But they have vaults the size of football field to hold the financial instruments.....
Even when the Twin Towers Collapsed they did not destroy Chases vaults 500ft below. The ones the size of 5 football fields.
Most people have no concept of how much money these big banks have....
And yes they are to Big to fail!
Oh of course they have banks (a lot of people know them and get regualry dividens) but that Tether situation was more or less founded when Wells Fargo (the monopolist on international remitance) was flagging (plus block) cryptocurrency transaction not only on Finex - no exchange was able to receive FIAT overnight from the community.
The logical idea was to decentralize bank accounts that they can not filter transactions easy.... of course not perfect but it is not crypto broken - it is the crappy banking system in America what is broken.
What I always find interesting that people from US think they are the only of the world when nobody give a shit on whole planet in meantime - lol.
