Institutional Foundations Of International Currency Credibility
- Eichengreen is worried that the dollar's future as the dominant global currency is threatened by political weakening in the United States, especially erosion of separation of powers and rule of law.
- Historically successful international currencies tended to come from issuers with strong economies, large trading roles, financial power, secure borders, military capacity, and long-run currency stability reinforced by domestic political constraints.
- Eichengreen cites the Roman Republic's denarius as benefiting from political constraints, including an independent Senate that limited leaders' ability to debase the currency.
- Britain's decline as a financial superpower created an opening for internationalization of the US dollar, enabled by construction of supporting financial institutions and infrastructure.
Enforcement And Information Frictions As Constraints On Cross-Border Credit Money
- The Spanish silver dollar is described as the first true global currency, circulating worldwide due to large-scale New World silver production and distribution.
- Eichengreen argues that bank money and credit innovations were historically difficult to use across very long distances and different cultures because abstract written contracts were hard to enforce.
- Spanish silver dollars cut into pieces of eight served as small change in the United States until 1857, and Spanish dollars had US legal tender status until near the Civil War.
- Eichengreen argues that because enforcement and information frictions were high, specie settlement was preferred for transactions spanning continents and cultures until 19th-century advances enabled global banks with far-flung branches to intermediate.
Legal Enforceability And Liquidity As Currency-Internationalization Mechanisms
- Eichengreen argues that moving from promissory notes to negotiable bills of exchange with enforceable holder rights enabled more liquid markets that increased the attractiveness of holding and using the Dutch guilder internationally.
- The Dutch advanced modern finance by creating a permanent share-funded Dutch East India Company and by developing negotiable bills of exchange with stronger legal enforceability for successive holders.
- Eichengreen argues that the Bank of Amsterdam functioned as a proto-central bank and that by some definitions it introduced early fiat-like money when certain claims became nonredeemable in specie.
Technology-Enabled Currency Competition (Stablecoins, Tokenization) As Expectations Not Yet Resolved
- The host states that the Chinese renminbi faces durable challenges in becoming a credible alternative to the US dollar.
- Eichengreen expects digital-era financial innovation, including distributed ledgers and tokenization, to increase the feasibility of alternatives to the dollar over time.
- The host states that stablecoins could potentially extend the dollar's network effects.
Internal Theoretical Disputes Shaping Interpretation Of Monetary Innovation
- Eichengreen sides with the view that physical means of payment preceded credit as the primary origin of money, contrary to a 'credit first' view.
- A debated explanation for Florence's decline is that it became excessively financialized and underinvested in upgrading tradable industries, and Eichengreen notes that this concern is echoed today about the United States.
- The host proposes that expanding base money via Spanish silver may have lubricated international commerce more powerfully than earlier bank-money expansion, and poses this as an open question about the need for currency elasticity beyond credit creation.
Watchlist
- Eichengreen is worried that the dollar's future as the dominant global currency is threatened by political weakening in the United States, especially erosion of separation of powers and rule of law.
Unknowns
- What specific, observable indicators show whether US institutional quality relevant to currency credibility (rule of law, separation of powers, constraints on opportunistic policy) is deteriorating, stabilizing, or improving?
- Are stablecoins measurably extending dollar network effects via increased cross-border usage, and if so in what contexts (trade settlement, remittances, offshore savings, corporate treasury)?
- What regulatory and institutional constraints will govern stablecoin reserve composition and redemption reliability in practice?
- What empirical evidence supports or refutes the claim that the renminbi faces durable barriers to becoming a credible USD alternative (e.g., capital account openness, investor protections, market depth) at present?
- To what extent are tokenized settlement rails or distributed ledger systems being adopted in ways that reduce reliance on USD-denominated instruments or USD-centered correspondent banking networks?
