Recently, there has been much discussion as to whether central bank digital currencies (CBDCs) should be introduced, and if so, how they should be designed. This article offers a historical perspective on this discussion, with a survey of early public bank (proto-central bank) “analog currencies” — circulating banknotes. Public banknotes were an experimental product when they were first issued in 16th-century Naples, but by the late 19th century, such notes could be found in most European countries. In between came all sorts of implementation difficulties: Egregious insider fraud, a real estate finance bubble, hyperinflation, rampant counterfeiting, and complete institutional collapse. Despite these many misfires, central bank-issued notes eventually became the default form of payment in virtually every country worldwide.
- Introduction of a new public payments instrument can entail serious operational and reputational challenges.
- Promoting the use of publicly issued instruments through exclusive privileges may simply motivate the private sector to innovate around these privileges.
- A successful public payments instrument will have monetary policy ramifications.
- Implementation difficulties notwithstanding, a lower-cost method of transacting can be very valuable to society, as was evidenced by the (eventual) widespread adoption of central banks’ notes.
