How many countries do NOT have a central bank?

Question

How many countries do not have a central bank that issues currency through a fiat system, or that utilises fractional reserves?

And, which countries are they? (what are their names?)

Answer 1

I believe as an Accountant that each government must have a central reserve or treasury where all its taxes, grants and donations are administered. The central bank plays the biggest role in setting up and improving an economy of any country since all fiscal and monetary policies originate from central banks. Unless a country is at war like Somalia then it must have a central bank.
