Bank Sounds

The oldest existing retail bank is Banca Monte dei Paschi di Siena (founded in 1472), while the oldest existing merchant bank was Berenberg Bank. Most countries have institutionalized a system known as fractional reserve banking, under which banks hold liquid assets equal to only a portion of current liabilities.
