Abstract
This article contributes to a recent debate between Barnett and Block : 711–716, 2009), Bagus and Howden : 399–406, 2009), Barnett and Block, Cachanosky and Bagus and Howden regarding the conceptual distinction between demand deposits and time deposits. It is argued that from an economic perspective there is nothing inherently fraudulent or illegitimate about deposit accounts that are available ‘on demand’, but that this relies on certain contractual provisions. Particular attention is drawn to option clauses and withdrawal clauses, which “solve” the problems raised by Barnett and Block, and Bagus and Howden. Previous authors have also neglected the asset side of banks balance sheets, and this is shown to further justify the legitimacy of fractional reserve banking.
