The Monetary Policy of Tazi is controlled by the country's central bank known as the Bank of Tazi. The local unit of currency is the taz. Aggregate banking statistics show that collectively the banks of Tazi hold 300 million tazes of required reserves, 75 million tazes of excess reserves, have issued 7,500 million tazes of deposits, and hold 225 million tazes of Tazian Treasury bonds. Tazians prefer to use only demand deposits and so all money is on deposit at the bank.
