Bundesbank/Dombret: Global derivatives markets in transition

In an article published in the Börsen-Zeitung, Dombret writes: "We expect mandatory CCP clearing to be introduced in the EU under EMIR from 2014 onwards... However, we must be aware that these regulatory requirements will turn CCPs into 'juggernauts' of the international financial system".

Counterparty risks can be reduced by relocating them to CCPs, which continuously evaluate  the open positions of the trading participants and demand a relatively high level of collateral. They can act as a risk buffer because of the extensive financial resources they have at their disposal; these comprise, among others, the clearing members’ collateral, a clearing fund,  obligations to make further contributions under additional margin calls, and the CCPs’ own  funds. According to the EU European Market Infrastructure Regulation (EMIR), in future CCPs will even have to be able to withstand the simultaneous default of the two largest  clearing members.

However, we must be aware that these regulatory requirements will turn CCPs into “juggernauts” of the international financial system. For this reason, particular attention will  have to be paid to the following points.

First, every CCP must have robust risk management structures in place. Competition among CCPs is growing more and more intense. This could lead to a race to the bottom, i.e. a  situation in which CCPs undercut each other in terms of the size and quality of their margin requirements. It is up to the regulatory and supervisory authorities to prevent this from happening. Above all, it has to be assured that the CCPs’ models for calculating margin requirements are sufficiently conservative.

Second, appropriate recovery and resolution regimes need to be available for CCPs in case of emergencies. The envisaged loss allocation rules are one core element in designing these regimes. The main problem with CCPs is that losses could only be distributed among clearing participants – a small group of market participants usually including, in particular, the globally active big banks – giving rise to potential contagion risks and domino effects.

Third, it must be ensured that central financial stability concerns do not take a back seat to issues of competition and efficiency. It would certainly be desirable from the derivative user’s viewpoint if the CCPs became interconnected, i.e. interoperable. Market participants would then not need to join a number of different CCPs in order to settle contracts with counterparties that use other CCPs. However, in the interests of financial stability, I would warn against subscribing to the idea of CCP interoperability prematurely. We cannot yet say for sure that we would actually be able to handle the new dangers that interoperability would create – in particular because of the new channels of contagion that would arise.

Fourth, in the derivatives market we must beware of focusing exclusively on the function performed by CCPs. It is possible that a small number of banks, too, may in future accumulate high levels of risks. I refer here to banks which, as general clearing members (GCMs), are directly linked to CCPs, making them the “eye of the needle” through which CCP clearing must pass. The GCMs’ central role has implications for financial stability on three accounts. They link the CCPs indirectly with each other, as in most cases they have connections with several CCPs; the default of one such bank would affect a number of CCPs simultaneously. Furthermore, the services provided by a GCM are crucial for its many clients; the question arises as to whether a GCM could be replaced. And finally, a bank acting as GCM faces additional risks, as it is liable vis-à-vis the CCP for the fulfilment of the obligations  of its clients, who are indirectly linked to the CCP through the bank.

These points all serve to illustrate why supervisors will continue to keep a close watch on the future development of the derivatives markets. In Europe, EMIR in particular offers a good starting point for supervisory authorities to ensure that the change now under way helps achieve greater stability in the financial system.
