A Digital Revolution in Global Payments
In 1905, an American traveler in Paris exchanged an American Express traveler’s check for francs, bypassing the need to carry cash or gold and avoiding cumbersome bank procedures. This early form of private payment relied on brand trust to facilitate cross-border transactions. Fast forward to 2023: a freelancer in Buenos Aires sends thousands of dollars to a client in the United States using USDT, without any bank involvement. This digital payment method echoes the convenience and privacy of traveler’s checks but operates on a blockchain-based system.
Both systems function as non-state-issued “quasi-currencies.” Traveler’s checks relied on signature verification and brand credibility, while stablecoins combine asset-backed reserves with on-chain algorithms. The former addressed the lack of a unified international settlement system in the late 19th century, while the latter responds to today’s digital age, where regulatory frameworks and the technical extension of dollar dominance intersect.
Stablecoins inherit the openness and efficiency of blockchain technology while remaining anchored to sovereign currency values. However, it is essential to avoid two common misconceptions:
First, some view stablecoins as “digital cash” without recognizing their dependence on real-world infrastructure. Although blockchain promotes decentralization, critical components—such as popular wallets like MetaMask and node services like Infura—are often operated by U.S.-based companies subject to American regulations. Centralized stablecoins like USDC also hold their dollar reserves in banks or funds approved by U.S. regulators.
Second, treating stablecoins as purely neutral technology overlooks their potential use as strategic tools. For instance, if state actors use stablecoins to evade sanctions, it could trigger stricter regulatory responses. Meanwhile, private stablecoins can facilitate gray-market activities, including money laundering and illegal trading.
Lessons from the Rise and Fall of Traveler’s Checks
The history of traveler’s checks offers valuable insights for stablecoins. Introduced in 1891 by American Express, these checks solved the challenges of cross-border cash exchange and carrying risks. They relied on brand trust rather than national monetary systems, creating an early form of non-sovereign international payment.
However, traveler’s checks faced significant challenges:
- Credit risk: During the Great Depression, doubts about American Express’s liquidity led some banks to refuse or limit check cashing.
- Fraud: Counterfeit checks became common in regions with weak verification mechanisms.
- Regulatory scrutiny: By the 1970s, stricter foreign exchange controls reduced their convenience. The rise of credit cards and ATMs further accelerated their decline.
Stablecoins face similar risks:
- Credit vulnerabilities: In March 2023, USDC’s value temporarily dropped when its issuer, Circle, revealed exposure to Silicon Valley Bank.
- Technical threats: Hacks, phishing scams, and smart contract bugs can lead to irreversible losses.
- Growing regulation: Authorities in the U.S. and E.U. are implementing stricter rules for transparency and compliance.
Unlike traveler’s checks, which could be reissued if lost, stablecoins face unique technological risks, such as private key loss or bridge failures.
How Stablecoins Are Used Today
Stablecoins serve critical roles in cross-border payments, inflation hedging, and financial privacy. Different users choose various digital currencies based on specific needs:
- Privacy-focused users often prefer DAI for its decentralized issuance and anonymity in DeFi applications.
- People in areas with poor internet access may use offline-capable digital currencies like e-CNY.
- Institutional users opt for compliant options like JPM Coin for secure, regulated settlements.
- Small businesses in developing regions rely on USDT to avoid local currency volatility and expensive transfer fees.
- Governments are testing central bank digital currencies (e.g., e-CNY) for welfare distribution and fiscal management.
- In DeFi and gaming ecosystems, stablecoins like USDC and DAI serve as collateral, medium of exchange, and liquidity tools.

In extreme financial environments, stablecoins offer censorship-resistant payment options. For example, users in sanctioned countries may turn to stablecoins for international settlements or as a store of value.
Regulatory Approaches and Challenges
Global regulators are paying close attention to stablecoins. Organizations like the FATF, FSB, and BIS have warned that unregulated stablecoins could challenge monetary sovereignty, capital flow controls, and anti-money laundering efforts.
Key regulatory trends include:
- United States: Proposed laws emphasize reserve transparency, audits, and 1:1 redemption guarantees.
- European Union: MiCAR regulations create a unified framework for investor protection and financial stability.
- Hong Kong and Switzerland: These regions are integrating stablecoins with traditional finance to strengthen their positions as innovation hubs.
Regulation is not just about technology—it reflects deeper concerns about monetary control. If privately issued digital currencies become widely used for salaries or international trade, they could partially replace sovereign systems.
Contrary to popular belief, most stablecoin transactions are traceable. Platforms like Ethereum and Tron record all transactions publicly. While wallet addresses aren’t immediately linked to identities, KYC checks on exchanges make it possible to trace funds when converted to fiat.
Macroeconomic Impact and Future Directions
From a monetary perspective, fully reserved stablecoins like USDC don’t expand the M1 or M2 supply because each token is backed by real assets. Instead, they increase the velocity of money (V), potentially amplifying inflationary or investment trends.
In countries with high inflation or strong demand for asset concealment, stablecoins may be held long-term, reducing local currency circulation and credit expansion. This could strain banking liquidity.
Some economists propose creating an “Me” (M-extended) category to account for these quasi-monetary assets. Although not official liabilities, they perform core monetary functions like value transfer and payment settlement.
Looking ahead, stablecoins will likely be shaped by international coordination and competing monetary policies. The rivalry between stablecoins pegged to different currencies could redefine aspects of the global financial order.
Frequently Asked Questions
What is a stablecoin?
A stablecoin is a type of cryptocurrency designed to maintain a stable value by being pegged to a reserve asset like the U.S. dollar or gold. This makes it suitable for everyday transactions and value storage.
How do stablecoins maintain their peg?
Most stablecoins use one of two mechanisms: asset backing (holding reserves in banks or treasuries) or algorithmic formulas that adjust supply based on demand. Each method has unique benefits and risks.
Are stablecoins legal?
Legality varies by jurisdiction. Many countries are developing regulations to address stablecoins’ role in payments, investments, and compliance with anti-money laundering standards.
Can stablecoins be used for international transfers?
Yes, stablecoins enable fast, low-cost cross-border payments. They are especially useful in regions with limited banking infrastructure or strict capital controls.
What are the risks of using stablecoins?
Risks include regulatory changes, reserve mismanagement, technical failures, and market volatility. Users should research each stablecoin’s design and governance before use.
How do stablecoins impact traditional finance?
They offer an alternative to conventional banking for payments and savings. However, widespread adoption could affect monetary policy and financial stability, prompting closer regulatory scrutiny.
