banks would have incentives to take on more risks
creditors may rely too heavily on regulator's work and lack of due diligence
customers would do business with regulated entity

hedging accounting
accounting for cash-flow hedge
accounting for fair-value hedge
use derivative to offset an exposure to changes in the fair value of an asset or liability
with hedging
bond's change in value will be recognized in income, rather than other comprehensive income
OCI
revenues that have yet to be realized
hedge exposure to cash-flow volatility
bond's change in value will not flow in income but rather than to other comprehensive income
rating arbitrage

The process also helps manager to understand the nature of portfolio. It ensures the capital is correctly allocated to support a reasonable level of risk.
stress testing measures the vulnerablility of individual exposure and portfolio to extreme yet possible events
regulatory dialectic
regulators would react to change in financial market and draft new regulations to respond to impacts of the changes
