Last week, the United States (US) passed its first major national legislation on cryptocurrency, establishing a regulatory framework for so-called stablecoins. This marks a significant milestone with potentially far-reaching implications for the Eurodollar market—a system in place since the mid-20th century that has supported global cross-border trade, foreign exchange swaps, and capital flows.
Tokens such as USDT (issued by Tether), USDC (issued by Circle), and others represent digital claims on US dollar assets. With a combined market capitalization exceeding $200 billion, stablecoins—though structurally distinct—serve a core function similar to Eurodollars: providing US dollar liquidity outside the US jurisdiction. However, unlike Eurodollars, which circulate through corresponding banking networks involving US financial institutions, stablecoins operate outside the traditional banking system. Instead, stablecoins operate via code, cryptography, and internet connectivity. This architecture enables peer-to-peer transfers over public blockchains, bypassing both conventional banks and legacy messaging systems such as SWIFT.
This shift in infrastructure is transformative. The low-friction, borderless nature of stablecoins expands access to US dollar liquidity beyond the traditional financial sector, enabling individuals in underserved regions to participate in global payments and finance using only a mobile device and a digital wallet.
Greater Financial Inclusion
One implication is the potential for greater financial inclusion. In emerging countries plagued by inflation, capital controls, weak institutions, or political instability, stablecoins are increasingly used as a store of value, medium of exchange, and remittance tool. Grassroots adoption has emerged in countries such as Argentina, Lebanon, Nigeria, Türkiye, and Ukraine—not driven by speculation but by the need for stable, portable, and accessible US dollar exposure. This trend could redefine global finance, as US dollar liquidity becomes programmable, portable, and personal.
Stablecoin issuers are required to hold reserves fully in segregated custodial accounts, backed by liquid US dollar assets such as short-term US Treasuries or deposits. Some issuers, such as Circle, are regulated in the US under state-level money transmitter licenses that impose reserve and disclosure requirements. However, this is not universally the case. Other issuers—such as Tether, based in regulatory havens—may hold reserves in riskier or less liquid instruments, raising concerns over transparency and redemption assurances.
Stablecoins essentially represent a potential democratization of US dollar access. Recognizing the implications of this shift, the US Congress recently passed the GENIUS Act, with an effective date in 2027. The act will establish a unified framework for dollar-pegged payment stablecoins. Only certified issuers, including foreign ones, will be permitted to issue stablecoins in the US. These issuers will be required to hold 100% liquid asset backing—specifically in short-term US Treasuries or dollars—and to submit monthly disclosures on the composition of reserves.
Meanwhile, Singapore and Hong Kong, China are building their own frameworks to support decentralized digital finance, focusing on reserve transparency, redemption mechanisms, and oversight of stablecoins pegged not only to the US dollar but also to other currencies. These global efforts reflect a shared understanding that robust regulation is essential for maintaining trust in digital payment infrastructure and safeguarding financial stability.
Destabilizing Effects
Yet this model comes with trade-offs. Because the assets backing stablecoins are kept off the books of traditional banks, they are effectively removed from the system that enables lending and credit creation. Unlike bank deposits, which fund loans and circulate through the economy, reserves kept for stablecoins are largely static.
Over time, this locking up of safe, liquid US assets may reduce the velocity of money and limit global banks’ ability to expand US dollar credit. Stablecoins may thus diminish the dollar’s role as a dynamic force in global credit expansion. As more US dollar assets are absorbed into stablecoin reserves, the pool of capital available for traditional financial intermediation shrinks, potentially reducing liquidity efficiency.
In addition, the Bank for International Settlements recently demonstrated that stablecoin inflows into short-term Treasuries may eventually affect the transmission channels of monetary policy through increased pricing volatility. As digital dollar infrastructure increasingly intersects with core financial markets, the macroeconomic consequences could be significant.
Geopolitical implications are also at play. Whereas Eurodollars still operate within the banking system, stablecoins may weaken US influence over dollar flows and reduce the effectiveness of sanctions and surveillance. Concerns over risks such as illicit finance and money laundering are also valid and growing.
Stablecoins are not simply replacing Eurodollars—they are evolving the concept of offshore US dollar liquidity. By making the dollar more programmable, accessible, and independent of banking intermediaries, stablecoins expand monetary power to the digital frontier. In doing so, they challenge traditional assumptions about who can issue, hold, and transmit US dollars. Whether this shift stabilizes or destabilizes global finance depends on how effectively the new system is governed, and international collaboration will be essential.
