Capital requirements in Pillar 1 or Pillar 2: does it matter for market discipline?
The results of this paper provide empirical evidence that regulatory capital ratios drive bank Credit Default Swaps (CDS) and that markets react more to changes in capital requirements if implemented via direct adjustments to Pillar 1 risk weights than imposed as a percentage of Risk-Weighted Assets (RWAs) under Pillar 2. In other words, market discipline on bank capital adequacy is sensitive to the composition of the capital requirement stack.
