The US dollar's origins long precede the founding of the United States, a historical reality that reshapes understanding of modern global finance. Journalist and financial historian Brendan Greeley articulated this perspective in a late-May 2026 podcast, arguing that the concept of the dollar is over 500 years old. This ancient lineage clarifies the nature of contemporary dollar forms, from bank deposits to the vast eurodollar market and emerging stablecoins. The fundamental question of what constitutes a dollar and who controls it requires this deep historical context.
Understanding the dollar's pre-American origins is critical as new digital forms like stablecoins challenge traditional monetary definitions. The modern monetary system is defined by a hierarchy of claims, with central bank money at the apex. Greeley’s research traces the dollar's lineage back to a silver coin minted in 16th-century Bohemia, known as the Joachimsthaler. This coin, shortened to "thaler," circulated widely in Europe and the American colonies, establishing a unit of account long before the 1792 Coinage Act.
The current macro backdrop features intense debate over the control of dollar-denominated assets outside the Federal Reserve's direct purview. The eurodollar market, estimated at over $13 trillion, operates beyond US banking regulations. This system echoes the historical use of Spanish pieces of eight and other commodity-based dollars that fueled global trade for centuries. The catalyst for revisiting this history is the rapid growth of crypto-dollar-pegged assets, which now represent over $150 billion in market value and pose similar questions about sovereignty and credit.
The scale of dollar claims existing outside direct Federal Reserve control dwarfs the traditional monetary base. The offshore eurodollar market is estimated to be several times larger than the $3.4 trillion M1 money supply within the United States. Stablecoins, the modern digital equivalent, have a combined market capitalization exceeding $150 billion as of mid-2026. This compares to a physical US currency in circulation of approximately $2.3 trillion.
Global trade invoicing demonstrates the dollar's entrenched role, with nearly 50% of all transactions conducted in USD. The dollar constitutes about 60% of all allocated central bank foreign exchange reserves, totaling over $7 trillion. This dominance is not a recent phenomenon. Historical data shows that even in the 18th century, Spanish American silver dollars were the de facto currency in many world regions, facilitating commerce decades before the US Mint's establishment.
| Monetary Instrument | Approximate Size (2026) | Primary Control Mechanism |
|---|---|---|
| Fed-Reserve Bank Deposits | $3.4 Trillion (M1) | Federal Reserve |
| Offshore Eurodollars | >$13 Trillion | Private Credit Markets |
| USD-Pegged Stablecoins | >$150 Billion | Blockchain Protocols |
This historical perspective implies that the dollar's strength derives more from network effects and global acceptance than solely from US fiscal policy. Sectors reliant on dollar funding, such as global shipping and commodities, are structurally long dollar liquidity regardless of its origin. Financial institutions with large international operations, like JPMorgan Chase (JPM) and Citigroup (C), benefit from their role as intermediaries in this broader dollar system. Their ability to manage both onshore and offshore dollar claims is a key competitive advantage.
A key risk is the potential for fragmentation between these dollar systems during periods of stress, as witnessed in the 2008 financial crisis. The limitation of this historical view is that it does not diminish the Federal Reserve's ultimate role as lender of last resort for the core system. Market positioning shows institutional investors increasing allocations to treasury management protocols on blockchains that handle stablecoins, betting on the convergence of traditional and digital dollar forms. This flow represents a long-term structural shift in how dollar liquidity is accessed and managed.
The primary catalyst to watch is the progression of US regulatory frameworks for stablecoins, with potential legislation expected by Q1 2027. The treatment of these assets as either bank deposits or a new class of monetary instrument will significantly impact their growth. Key levels to monitor include the relative size of the stablecoin market against the monetary base; a crossover above 5% would signal a major acceleration in adoption.
The Federal Reserve's decisions on a potential digital dollar will be another critical signal. Any official movement towards a central bank digital currency (CBDC) would represent a direct response to the proliferation of private dollar claims. Forex traders should watch the DXY index for reactions to these developments, with a sustained break below 100 or above 105 indicating a significant reassessment of the dollar's global standing based on these new forms of competition and complementarity.
The dollar's longevity suggests a profound resilience built on its function as a global unit of account, not just a national currency. This historical precedent indicates that network effects and institutional inertia make a rapid displacement by another currency unlikely. The stability is now tested by digital innovations, but the core function—a trusted claim for final settlement—remains the bedrock of its value, a concept explored in Fazen Markets' analysis of monetary sovereignty.
A eurodollar is a US dollar-denominated deposit held in a bank outside the United States, free from the direct regulatory oversight of the Federal Reserve. A dollar in a US bank is a direct liability of that bank, which is itself subject to Fed regulation and deposit insurance. The eurodollar system is a vast, private network of interbank liabilities that creates dollar liquidity globally but also carries higher counterparty and liquidity risk, as it lacks a formal lender of last resort.
Stablecoins represent a new, technology-enabled form of private money creation that operates outside the traditional banking channel. While they currently represent a small fraction of total dollar claims, their growth trajectory is steep. A systemic challenge would require stablecoins to scale to a size where they significantly influence short-term funding rates or transaction volumes, potentially prompting a regulatory response to either integrate them into the existing system or constrain their growth.
The dollar’s identity as a global network of claims predates the US, making its dominance a function of history as much as policy.
