Hybrid, they have the technology and logistics firmly in hand here- its just the reasoning behind it that doesnt make sense.
When you buy real estate, regardless of how your money got to the bank, for instance a wire transfer from NYC-
the final closing takes place in cash.
in a room, inside the bank, the total amount is brought out in US $100 bills, run thru the digital counting machine, and put on the table.
Then the buyer must physically push the huge pile of cash across the table, to the seller.
Dozens of papers are signed, smaller piles are pushed over to the agents, lawyers, banker for taxes, and escribano.
Then, the whole stack is run back thru the counting machine, and wheeled out.
In most cases, the seller wants pesos- so an even LARGER stack of argentine cash is wheeled out on a cart, run thru the counting machine, and presented to the seller.
Sometimes, it is then hauled off in a briefcase.
Other times, its wheeled back and "deposited" into the sellers account at the same bank.
Other times, hired armed guards take it out to a hired armored car, and it is hauled off, in cash, to ANOTHER bank.
the ways of Argentine High Finance are not like what you are used to.
This is all considered to be perfectly normal, and many parts of it are either legally or contractually required.
Welcome to the other side of the mirror.
