Finance & Development – IMF
In this December 2025 article, Eswar S. Prasad examines the rise of stablecoins and their implications for the global financial system. Originally, cryptocurrencies aimed to decentralize finance and reduce reliance on traditional intermediaries. However, stablecoins—designed to provide price stability—have evolved in ways that contradict these initial goals. While they improve payment efficiency and financial access, they also risk reinforcing concentration and existing power structures in global finance.
From decentralization to institutional dependence
Early crypto innovations sought to eliminate intermediaries and democratize financial services. Yet, decentralized cryptocurrencies such as Bitcoin proved unsuitable as everyday payment instruments due to volatility and scalability limitations. As a result, stablecoins emerged as a more practical alternative.
Stablecoins maintain their value by being backed by reserves such as government bonds or central bank currencies. This design makes them more stable but also introduces dependence on trusted institutions. Consequently, governance is centralized rather than decentralized. Issuers control access, validate transactions, and define system rules, which contrasts with the original vision of decentralized finance.
Efficiency gains and financial inclusion
Despite these limitations, stablecoins provide tangible benefits. They reduce transaction costs and improve the speed of payments, especially across borders. Migrants, for example, can send remittances more quickly and at lower cost. Similarly, businesses can complete international transactions with fewer delays.
Stablecoins also have the potential to expand financial access. By integrating users into digital payment systems, they can reduce barriers for individuals and firms, particularly in developing economies. In this sense, they partially fulfill the original promise of expanding access to financial services.
Concentration risks and systemic implications
The article highlights a key paradox: stablecoins may increase financial concentration rather than competition. Large corporations and major financial institutions are well positioned to issue stablecoins, leveraging their scale and existing infrastructure. This could marginalize smaller banks and reinforce the dominance of large players.
At the international level, stablecoins may strengthen the current monetary system. Dollar-backed stablecoins are the most widely used, which could further entrench the global role of the U.S. dollar. At the same time, smaller economies face risks. In countries with weak currencies, individuals may prefer stablecoins, potentially undermining domestic monetary systems.
Regulation and the future of stablecoins
The article argues that effective regulation is essential to balance innovation and risk. Stablecoins expose inefficiencies in existing payment systems, but they also create new vulnerabilities. These include risks related to illicit financial activity, fragmented payment infrastructures, and increased systemic dependence on private issuers.
A coordinated international regulatory framework would be the most effective solution. However, such cooperation is difficult in a fragmented geopolitical environment. Without coordination, national approaches may diverge, limiting the effectiveness of regulation.
The article concludes that stablecoins highlight both the potential and the risks of financial innovation. While they improve efficiency and accessibility, they may ultimately lead to greater concentration and instability if not properly regulated.
