Floored: Basel III rethink upsets IRB dominance

The Basel III overhaul has stirred up the banking regulatory landscape by introducing an output floor, which challenges the long-standing dominance of internal ratings-based (IRB) approaches. While this change means banks might rely less on their own risk models, it doesn't signal the complete end of IRBs. The shift underscores a broader move toward more standardized and regulatory-driven approaches to risk management, which could lead to more uniform practices across the global banking system. This change matters because it affects how banks assess and manage their risk profiles, ultimately influencing everything from lending practices to capital requirements.
