Until recently, for most banks adopting an Internal Ratings Based-approach, the focus of Basle was Pillar 1.
"Developing, validating and creating a user-test history has been a huge investment in time and money for the major international banks," said Paul Waterhouse, Standard & Poor's Risk Solutions. "But now, Pillar 2 looms large and has the potential to undermine investment to date. Of course, for those banks that work through Pillar 2 successfully, the regulatory hurdle it represents for others can be a profound source of competitive advantage."
Executing an enterprise-wide, transparent risk capital system and firm-wide portfolio approach were among the key challenges faced by banks as they move to adopt Pillar 2, Paul Waterhouse said.
"The irony for some of the more sophisticated banks that moved early to more complex economic capital management is that business unit or department-specific execution may actually now challenge meeting Pillar 2 as central to Pillar 2 is firm-wide, transparent and consistent implementation of risk capital management," Paul Waterhouse said. "Internal Rating Based banks will need to demonstrate a robust and objective approach to an integrated risk capital calculation. This includes having an effective, codified and transparent system for evaluating the impact of guarantees, group structures, inter-asset class correlations, pricing and limit setting and management."
"While process has been key for Pillar 1, much of it is related to the technical execution of executing and validating probability of default (PD), Loss Given Default (LGD) and Exposure At Default (EAD) measures," said Waterhouse. "With Pillar 2's focus on firm-wide overall capital adequacy, the focus switches to ensuring a 'top down', integrated risk position and a strategy around this. Issues such as liquidity risk and legal risk become much more central and, hence, so do the processes for managing and calculating these."
