IOSCO examines regulatory-driven market fragmentation and considers how to enhance cross-border cooperation
04 June 2019
The Board of the International Organization of Securities Commissions published a report that examines instances of regulatory-driven fragmentation in wholesale securities and derivatives markets and considers what actions regulators can take to minimise its adverse effects.
The report, titled Market Fragmentation and Cross-border Regulation, focuses on market fragmentation that arises as an unintended consequence of financial regulation. It provides examples of market fragmentation that IOSCO members consider to be significant and potentially harmful to the oversight and supervision of financial markets. The report also examines the progress made by IOSCO members in using deference, and the regulatory mechanisms and tools associated with this concept (e.g., passporting, substituted compliance, recognition/equivalence). In doing so, the report follows up on a 2015 IOSCO report on cross-border regulation andseeks to identify remaining challenges that can restrict cross-border activities. Regulators have become increasingly aware of the risks associated with unintended market fragmentationand are cooperating more among themselves to mitigate its effects through deference and its associated tools. Bilateral arrangements in the form of MoUs continue to be a common tool used by regulators, particularly with respect to information exchanges. Regulators also have developed novel processes to work multilaterally to the benefit of the markets they oversee.
Nevertheless, several challenges remain and strengthening cooperation between authorities could further assist in addressing adverse effects on the financial system stemming from market fragmentation. IOSCO’s concerns about the risks of fragmentation are shared by other international organizations and policy makers. These include the G20, which has made market fragmentation a top priority, and the Financial Stability Board, which also published today a paper on market fragmentation. The report proposes potential measures that IOSCO and relevant national authorities could explore to mitigate the risk, and potential adverse effects, of fragmentation on global securities markets. These measures include ways to foster further mutual understanding of one another’s legislative frameworks, deepen existing regulatory and supervisory cooperation and consider whether there are any good or sound practices that can be identified regarding deference tools. The IOSCO Board will decide on its approach to these next steps in the second half of this year. J. Christopher Giancarlo, Chairman of the US Commodity Futures Trading Commission, co-chair of the IOSCO work on market fragmentation said: “The use of deference can be a powerful way to mitigate the risks arising from fragmentation in cross-border trading markets. While its use has increased, the report highlights areas where further improvements could be sought while allowing members to continue choosing their own underlying tools to achieve it.” Jun Mizuguchi, Deputy Commissioner for International Affairs at the Japan Financial Services Agency, also an IOSCO co-chair on this work said: “Since the financial crisis, well-intentioned regulatory implementation has sometimes led to unintended fragmentation of markets. In the spirit of the G-20 leaders in Pittsburgh, this report welcomes the advances made by regulators in deferring to one another but encourages us towards further, smoother, cross-border collaboration.”
