The issuance of digital currency by central banks is not an end in itself but a means to an end. The primary considerations are to reduce transaction costs, enhance market efficiency, and better maintain financial order and monetary market integrity under current technological and market conditions.
Digital currency issuance is a widely discussed topic today. Theoretical analyses and strategic choices regarding its implementation vary widely. This article focuses on examining the concept of digital currency from a macroeconomic perspective, analyzing its issuance system, and exploring strategic pathways for issuing digital currencies, especially central bank digital currencies (CBDCs).
Understanding Digital and Fiat Digital Currencies
Money and Fiat Money
The definition of money has long been debated. The International Monetary Fund (IMF), from a macroeconomic standpoint, defines and measures money based on three key aspects:
- Monetary Functions and Financial Instruments: Money is an abstract concept manifested through various financial instruments that perform monetary functions, such as currency, deposits, foreign exchange, bills, and short-term debt tools. These functions include serving as a unit of account, medium of exchange, means of payment, and store of value. Different instruments emphasize different functions, and their monetary strength—often described as liquidity—varies. The IMF categorizes monetary instruments into tiers: M0 (physical currency, the most liquid), M1 (M0 plus demand deposits), M2 (M1 plus savings and time deposits), and broader liquidity measures that include stocks and bonds.
- Monetary Issuing Sectors: This perspective identifies which sectors issue financial instruments classified as money. Key issuers include central banks (high-powered money), deposit-taking financial institutions (deposit creation), non-financial corporations (e.g., commercial paper), and non-resident sectors (foreign exchange instruments). Households, non-issuing corporations, and local governments are generally excluded.
- Monetary Holding Sectors: This approach measures money based on the financial instruments held by sectors affecting the macroeconomy, excluding central banks, deposit-taking institutions, and the central government.
Key insights from these definitions include:
- Money comprises various financial instruments, not just physical currency.
- The monetary issuance system involves multiple entities: central banks, financial institutions, and non-financial corporations.
- Each issuer plays a distinct role: central banks provide high-powered money, financial institutions create deposit money, and non-financial corporations issue less liquid instruments.
Digital Currency and Fiat Digital Currency
Terms like virtual currency, e-money, digital currency, and fiat digital currency are often used inconsistently. This article defines them based on the issuing sector and the monetary properties of digital instruments. "Digital" here includes both cryptography-based forms (e.g., blockchain) and traditional account-based digitalization.
- Virtual Currency: Issued by non-financial corporations, these are digital currencies not directly convertible to fiat money. They operate outside the fiat system and function more as virtual assets or commodities (e.g., coupons, game credits, cryptocurrencies like Bitcoin). Their monetary properties are weak.
- E-money: Issued by deposit-taking financial institutions, these are digital currencies directly convertible to fiat money (e.g., debit cards, online banking). Non-bank payment tools like Alipay or WeChat Pay, which link to deposits via reserves, also qualify. E-money is integral to the fiat system.
- Digital Currency: Broadly, it includes both virtual currency and e-money. Narrowly, it refers only to digital virtual currencies, including private cryptocurrencies.
- Fiat Digital Currency (CBDC): Issued by central banks, it represents a digital form of base money (currency and reserves) and is a central bank liability. While reserves are already digital, many central banks are exploring digital currency issuance, often termed central bank cryptocurrencies.
Critical points:
- Different issuers play varied roles in digital currency issuance.
- The monetary strength of a digital currency depends on its清算 (settlement) relationship with central bank money.
- The nature of the issuer doesn’t inherently determine monetary strength; central banks could theoretically清算 virtual currencies without reclassifying their issuers as financial institutions.
Digital Currency Issuance and Financial Systems
Digital currency issuance involves integrating digital currencies into the fiat system and managing their distribution according to set rules. This process requires both technological support and economic adjustments, carrying risks related to credit and payments. Mitigating these risks necessitates robust financial systems, primarily market access and payment settlement frameworks.
Market Access Systems
These include institutional and instrument access rules. Institutional access determines which entities can become monetary issuers, requiring them to meet specific conditions, comply with regulations, and undergo supervision to prevent risks. Instrument access defines which digital financial tools qualify as money based on functional regulation.
In today’s credit-based economy, centralized货币 issuance is crucial. Central banks, as primary authorities, must manage digital currency issuers and instruments within a unified regulatory framework. For instance, e-money is already regulated through banking licenses, payment institution approvals, reserve requirements, and security issuance rules.
Virtual currencies, however, generally remain outside this system due to their limited scope and impact. But as cryptocurrencies gain monetary traits, their potential inclusion demands study.
Payment and Settlement Systems
Payment infrastructure is vital for digital currency issuance, encompassing rules, procedures, and operational scope. This includes account management, payment tool regulations, anti-money laundering measures, and system oversight.
In fiat systems, central banks typically operate payment networks, serving banks and licensed clearers, while banks serve individuals and firms. Virtual currencies, being excluded, rely on self-maintained systems or community governance (e.g., blockchain networks).
Financial System Innovation as a Key Focus
Digital currency innovations, driven by internet technologies, challenge traditional monetary systems. Addressing market needs and management demands institutional creativity. With numerous digital currencies emerging—many bypassing central banks—there’s a risk to monetary authority and policy effectiveness.
While blockchain technology is important, innovating financial systems around digital issuance is critical. Without institutional improvements, technological advances alone won’t resolve market chaos.
Pathways for Innovating Digital Currency Issuance
Central banks issue digital currencies to reduce costs, boost efficiency, and uphold financial stability. Thus, innovation should be viewed macroeconomically.
- Broad Digital Currency (E-money): Already part of the fiat system, e-money requires optimized清算. Central banks should enhance centralized清算 to improve payment efficiency. Institutions with money-creation capabilities could be broadened under unified management, and systemically important players (e.g., large payment firms) might receive direct central bank清算.
- Narrow Digital Currency (Virtual Currency): Currently small-scale and fragmented, virtual currencies pose limited macroeconomic threats. Key questions include whether to integrate them into the fiat system, how to regulate them if not, and how central banks might provide清算—including opening balance sheets to non-banks. This demands tailored market access and payment rules. Anonymous, decentralized cryptocurrencies need proactive regulation.
- Fiat Digital Currency (CBDC): Accelerating CBDC research can bridge digital and traditional finance. CBDC development involves both technological and institutional innovation. Issuing to traditional banks may require清算 system overhauls; issuing to non-banks or individuals could reshape the central bank–commercial bank dual system, necessitating careful feasibility assessment.
Ultimately,货币 issuance hinges on government credit. Whatever model is chosen, safety, stability, efficiency, and cost reduction must be paramount.
