Stablecoins have emerged as a groundbreaking financial innovation, promising the stability of fiat currencies combined with the efficiency and decentralization of blockchain technology. Peter Bofinger’s 2025 paper, “Stablecoins and the Future of Money: Economic Principles and Policy Implications,” rigorously evaluates the promise, risks, and policy challenges that polarized narratives often overlook.
The research paper employs a multi-dimensional methodological approach consisting of a theoretical framework, comparative system analysis, and empirical market data evaluation. It begins with a clear taxonomy differentiating stablecoins into “bond-based” stablecoins collateralized by short-term government bonds offering safety and direct payment capabilities, and “bank-based” stablecoins backed by bank deposits with higher systemic risks. This framework underpins an analytical comparison of stablecoin payment systems against traditional cash, bank deposits, and central bank digital currencies (CBDCs), focusing on distinctions between payment objects and the infrastructures enabling direct versus indirect exchanges.
Empirically, the paper evaluates stablecoin market dynamics by analyzing market capitalization, issuer dominance, transaction volumes, and price stability, leveraging data from sources such as CoinGecko, VISA analytics, and Statista. This assessment reveals significant network effects manifesting as a duopoly of issuers and a small number of blockchains, shaping the robust yet concentrated market structure. These methodological components collectively enable a nuanced examination of stablecoins’ functions, economic impact, and policy challenges in the evolving financial ecosystem.
Two Worlds of Stablecoins: Bond-based vs Bank-based
- Bond-Based Stablecoins: These stablecoins are collateralized primarily by short-term government bonds. This design offers relative safety, as they are backed by highly liquid and secure government securities. Bofinger highlights issuers like USDT and USDC as exemplars that have maintained peg stability and resilience during market shocks. Their ability to support direct international payments without intermediaries contrasts sharply with traditional, layered banking systems
- Bank-Based Stablecoins: These coins are collateralized largely by bank deposits, exposing them to vulnerabilities akin to those of traditional banks. Such stablecoins can create systemic risk through a “doom loop” between stablecoin runs and bank bank runs, a phenomenon underscored by the Silicon Valley Bank crisis impacting stablecoin liquidity in 2023-24
The paper stresses that this fundamental distinction informs the different economic roles these stablecoins play and their varied regulatory challenges.
Market Dynamics, Network Effects, and Dominant Players
The research analyses the oligopolistic nature of stablecoin markets, driven by strong network effects with only a handful of major issuers dominating the landscape. The US dollar overwhelmingly dominates as the denomination currency, reinforcing a duopoly structure in terms of issuers and platforms. This concentration raises issues for new entrants but also fosters interoperability within the leading stablecoin ecosystem
Use Cases: Practical, Yet Limited
Bofinger identifies the primary current use cases of stablecoins as:
- Vehicle in Crypto Exchanges: Serving as essential tokens enabling trading liquidity.
- Cross-border Payments: Offering instant, low-cost, peer-to-peer global payments that bypass several costly intermediaries inherent in traditional systems like SWIFT.
- Storing Large Transaction Balances: Preferred by large businesses over unsecured bank deposits for treasury management.
On the other hand, stablecoins have struggled to penetrate retail payment markets due to regulatory constraints such as bans on interest payments, lack of embedded credit functionalities, and interoperability issues across existing payment networks. The study specifically provide crucial insight into how bond-based stablecoins may indirectly affect money supply and government debt markets by purchasing treasuries. This mechanism could, in theory, influence central banks’ monetary control and demand for sovereign debt globally
Meanwhile, bank-based stablecoins could amplify systemic fragility due to direct links with banking institutions, potentially accelerating financial crises through destabilizing liquidity runs This distinction iterates the need of distinct and appropriate regulatory frameworks.
Despite being designed for retail use within the eurozone, the proposed Digital Euro does not present a strong challenge to dominant USD-denominated stablecoins. Bofinger warns of Europe’s growing financial sovereignty risks as a few US-based stablecoin issuers consolidate their influence in the global payments architecture. He advocates for integrating national payment infrastructures and sensible regulatory reforms like amending MICA to mitigate fragmenting effects and strengthen European sovereignty
Policy Recommendations and The Way Forward
- Craft balanced regulation to mitigate financial stability risks, especially those posed by bank-based stablecoins, without stifling innovation.
- Promote the development of interoperable and independent payment infrastructures to reclaim monetary sovereignty and competition in payment markets.
- Explore the issuance of central bank tokenized deposits, particularly for wholesale cross-border payments, ensuring safety and control in evolving digital environments.
- Encourage transparency, overcollateralization, and prudent governance among stablecoin issuers to uphold financial resilience.
Stablecoins signify an intersection of money, technology, and regulation. This study is a timely reminder that their potential will only be realized through thoughtful policy design addressing financial stability and sovereignty concerns without undermining innovation. Whether stablecoins become the “next leap” or a fleeting mirage depends on policymakers’ and industry’s ability to harness their promise responsibly
