Under Free Banking, It Is Unlikely That the Public Would Accept Inconvertible Notes and Abandoning the Gold Standard Becomes Inconceivable

"Free banking" denotes a régime where note-issuing banks are allowed to set up in the same way as any other type of business enterprise, so long as they comply with the general company law. The requirement for their establishment is not special conditional authorisation from a Government authority, but the ability to raise sufficient capital, and public confidence, to gain acceptance for their notes and ensure the profitability of the undertaking. Under such a system all banks would not only be allowed the same rights, but would also be subjected to the same responsibilities as other business enterprises. If they failed to meet their obligations they would be declared bankrupt and put into liquidation, and their assets used to meet the claims of their creditors, in which case the shareholders would lose the whole or part of their capital, and the penalty for failure would be paid, at least for the most part, by those responsible for the policy of the bank. Notes issued under this system would be "promises to pay," and such obligations must be met on demand in the generally accepted medium which we will assume to be gold. No bank would have the right to call on the Government or on any other institution for special help in time of need. No bank would be able to give its notes forced currency by declaring them to be legal tender for all payments, and it is unlikely that the public would accept inconvertible notes of any such bank except at a discount varying with the prospect of their again becoming convertible. A general abandonment of the gold standard is inconceivable under these conditions, and with a strict interpretation of the bankruptcy laws any bank suspending payments would at once be put into the hands of a receiver.
