The combination that produced economic stability was restriction of supply of new notes, a government monopoly on the issuance of notes directly and indirectly, a central bank, and a single unit of value. As notes devalued, or silver ceased to circulate as a store of value, or there was a depression, governments demanding specie as payment drained the circulating medium out of the economy. At the same time there was a dramatically expanded need for credit, and large banks were being chartered in various states, including those in Japan by 1872. The need for stability in monetary affairs would produce a rapid acceptance of the gold standard in the period that followed.
