Global currencies have a rich past and poor future | The Big View

Political stability underpins economic dominance

Global currencies require rule of law, separation of powers, and credible alliances to deter opportunistic behavior by issuers and give creditors voice, not just economic size.

Financial innovation drives currency ascendancy

From Florentine banking to the Bank of Amsterdam, innovations like bookkeeping transfers and fiat currency have consistently enabled currencies to dominate international trade.

Military defeat often ends currency reigns

The Dutch Guilder collapsed not from economic failure but from French military conquest at the end of the 18th century, highlighting the critical link between geopolitical power and monetary status.

Gold window closure did not end dominance

Despite Nixon ending dollar convertibility in 1971 and shrinking US global GDP share, tolerable monetary policy and crisis management preserved trust in the greenback.

Alternatives remain uncompetitive at scale

The euro has made zero progress as a global currency in 25 years, while the Chinese renminbi accounts for only 9% of global FX turnover compared to the dollar's 90%.

Incumbency advantages create sticky demand

Network effects and the absence of scalable alternatives have maintained dollar indispensability for trade and reserves even as the US economic footprint shrank.

New payment rails threaten dollar intermediation

Blockchain and fast payment systems like Singapore-Thailand QR code links allow direct cross-border transactions that bypass SWIFT, US correspondent banks, and dollar conversion.

Stable coins unlikely to secure dollar supremacy

Private stable coins resemble risky 19th-century free banking systems and lack state-backed protections, as demonstrated by the SVB/Circle incident revealing fragility in private issuance.

Multicurrency fragmentation is the likely future

Digital innovation is eroding network effects that historically locked users into dominant currencies, enabling a more decentralized international monetary system where multiple currencies coexist.
