Term- Base Money/ High Powered Money / Sovereign Money

Central banks call this M0 or Base Money.

"Sovereign Money"  in the Green policy context generally means "The direct control of the money supply by the public sector, including money both in its physical form (currency notes/ coin) and in electronic form (deposits)." Some definitions also include the item credit along with deposits and currency [BC definition May 15]. Minus credit, If we substitute reserve deposits at the cental bank for "deposits" then it is equivalent to M-zero or Base Money. However, if credit is included, then what is being said is that sellers cannot propose that the buyer pay them later for the goods sold, since this is providing credit to the buyer.
