To mitigate systemic risk, some regulators have advocated the greater use of centralized counterparties (CCPs) to clear Over-The-Counter (OTC) derivatives trades. Regulators should be cognizant that large banks active in the OTC derivatives market do not hold collateral against all the positions in their trading book and the paper proves an estimate of this under-collateralization. Whatever collateral is held by banks is allowed to be rehypothecated (or re-used) to others. Since CCPs would require all positions to have collateral against them, off-loading a significant portion of OTC derivatives transactions to central counterparties (CCPs) would require large increases in posted collateral, possibly requiring large banks to raise more capital. These costs suggest that most large banks will be reluctant to offload their positions to CCPs, and the paper proposes an appropriate capital levy on remaining positions to encourage the transition.

In this work, Christopher Chen examines and compares the regulation of over-the-counter derivatives in Hong Kong and Singapore, the two largest international financial centres in Asia Pacific. Chen analyses current or proposed regulations on trade reporting, centralised clearing and mandatory exchange trading mandates regarding OTC derivatives against the backdrop of reforms of international financial regulatory structure after the global financial crisis. The article also relates the reforms in Asia to development in major Western markets such as the US, the UK or the European Union. Apart from technical comparison and dissecting of content of rules from different angles, his work also examines the rationale behind those reforms and policy concerns behind Asian adoption of the regulatory mandates prescribed by G20 as well as potential policy concerns (such as competition and extraterritoriality) in a market that is dominated by Western banks.

The OTC derivatives market has been hit by a massive wave of regulatory change. Capital and margin requirements have increased, trade reporting has been mandated, and execution mechanisms are evolving. Most of all, central clearing is being imposed for many transactions. OTC Derivatives: Bilateral Trading and Central Clearing explains the new rules and the new models. It discusses the traditional bilateral market, then sets out how this will change due to mandatory central clearing and the new ways in which OTC derivatives will have to be traded, reported, and processed. The risks of OTC derivatives clearing houses are discussed in detail, as are the protections that CCPs have against these risks. The book also looks at alternatives to some of the policy decisions that have been made, showing the balance between costs and benefits of various different approaches to derivatives market stability. The book is both a detailed primer on OTC derivatives clearing and a powerful insight into post-crisis financial regulation. Key features of the book include: • A discussion of the capital rules for OTC derivatives counterparty credit risk in Basel III; • An account of OTC derivatives trade processing in both bilateral and cleared markets; • A detailed account of the risk profile of OTC derivatives CCPs; • An explanation of the risks run in various collateral segregation models; and • A comparison of various macro-prudential tools for enhancing the financial stability of OTC derivatives markets.

New regulatory data reveal extensive price discrimination against non-financial clients in the FX derivatives market. The client at the 90th percentile pays an effective spread of 0.5%, while the bottom quarter incur transaction costs of less than 0.02%. Consistent with models of search frictions in over-the-counter markets, dealers charge higher spreads to less sophisticated clients. However, price discrimination is eliminated when clients trade through multi-dealer request-for-quote platforms. We also document that dealers extract rents from captive clients and market opacity, but only for contracts negotiated bilaterally with unsophisticated clients.
