As emerging market economies continue to deepen and modernize their financial systems, one of the foundational elements for stable and efficient markets is the development of a robust repurchase agreement, or repo, market. Repos are essential for liquidity provision, collateral management, and effective monetary policy transmission. However, without well-designed infrastructure and risk controls, repo markets can also introduce systemic vulnerabilities. In this regard, recent work by the U.S. Treasury Market Practices Group (TMPG) offers a timely blueprint for strengthening repo market practices in developing economies.
One of the most critical insights from the TMPG’s best practices is the importance of market transparency and integrity. In the U.S. market, participants are expected to avoid manipulative trading strategies such as spoofing, layering, and artificial quoting. Instead, there is a strong emphasis on clear communication, fair pricing, and truthful market conduct. These principles are crucial for emerging markets where market surveillance mechanisms may still be evolving. By embedding codes of conduct and clear rules on trade transparency, these markets can foster greater investor confidence and deeper secondary market activity.
The TMPG also underscores the significance of robust risk management practices. Despite the high credit quality of government securities and short maturities involved, repo transactions still expose participants to counterparty credit and liquidity risks. In the U.S., these risks are typically mitigated through the use of haircuts, variation margin, and portfolio netting agreements. In many emerging markets, however, these practices are inconsistently applied or absent altogether. Adopting structured and enforceable margining frameworks can help avoid episodes of liquidity stress and minimize the domino effect of counterparty failures.
A particularly revealing finding in the TMPG’s consultative white paper is the fragility in the non-centrally cleared bilateral repo (NCCBR) segment. Many transactions in this space are executed without haircuts, often due to competitive pressures, resulting in opaque and potentially risky leverage buildup. This lesson is highly relevant for emerging markets, where regulatory oversight and data collection on bilateral trades may be limited. Instituting standardized data reporting and encouraging greater use of central clearing or triparty structures can reduce these vulnerabilities and enhance market resilience.
Another emerging challenge lies in counterparty risk exposure in dealer-to-client trades. The TMPG notes that in the U.S., dealers often bear the full cost of central counterparty margin requirements on behalf of clients. While this practice may promote market activity, it also creates concentration risks that are not sustainable over time. For emerging markets, careful consideration is needed when designing margin allocation policies to ensure that risk is equitably shared across trading participants and not disproportionately borne by intermediaries.
Finally, the TMPG advocates for strong internal control systems and operational resilience, including cyber risk preparedness. In an era of increasing automation and digital dependence, the potential for systemic disruption due to cyberattacks or operational failures cannot be overlooked. Emerging markets should invest in building regulatory and institutional capacity to support market continuity, including backup protocols, system testing, and coordination with service providers.
In conclusion, while the structure and sophistication of U.S. repo markets may differ significantly from those in developing economies, the underlying principles of transparency, prudent risk management, and operational discipline are universally applicable. Emerging markets have a rare opportunity to design repo markets that are not only efficient and liquid but also resilient and aligned with global best practices. By adapting and integrating lessons from the TMPG’s guidance, policymakers and market participants can lay the foundation for safer and more robust financial ecosystems.
