What are the key differences between ICAAP and CCAR frameworks for assessing capital adequacy in financial institutions?

The key differences between the ICAAP and CCAR frameworks for assessing capital adequacy in financial institutions are that ICAAP is an internal process where banks assess their own risks and determine their capital needs, while CCAR is a regulatory process where banks are required to submit their capital plans to regulators for approval. Additionally, ICAAP focuses on a bank's overall risk profile and capital adequacy, while CCAR specifically evaluates a bank's ability to withstand stressed economic conditions.
