In a fiat currency if I do an electronic transfer for US$200,000 from say a Bank of America current account to Citibank how do the banks account for/handle the transfer?
Are we just relying on trust that if recipient bank Citibank increases its asset book and liability book by US$200,000 then the sending bank reduces its asset list and liability list by US$200,000?
If that's the case, who audits the banks to ensure that all the books balance and we haven't created too much money (outside of frictional reserve limit/allowances)?
