Over the past five years, the OTC derivatives market showed an impressive resilience in levels of market activity, which are now above pre-crisis levels in outstanding notional value. This confirms its systemic importance. Current volatility of the gross market values and gross credit exposures can be attributed to the uncertain market conditions for the global economy. Distribution of derivatives instruments has remained relatively constant over the past decade. Central clearing and portfolio compression is developing fast for interest rate and credit derivatives, while progress in other asset classes is fairly slow. The OTC derivatives market is structured with a highly interconnected system of financial institutions. But composition is changing from a dealer-driven business to a more diversified environment, with other financial institutions (such as CCPs and investment funds) playing a greater role.
