30. Capital management II - regulatory capital Flashcards
State the 3 tiers of capital outlined in the Basel Accords
- Equity and disclosed reserves
- Other reserves and various debt instruments
- Certain types of shorter-dated capital (eg unsecure, subordinated debt with min maturity of 2 years)
How is capital calculated under Basel II
Credit risk (1)
- Based on risk weighted assets using standard or IRB approach
-No allowance for diversification
Market risk (2)
- Standardised approach or an asset model to calculate 10-day 99% VaR
Operational risk (3)
- Based on scaled gross income (standardised or basic indicator) or …
… using advanced measurement approach based on internal models and scenario analysis
Total RWA = 1 + 12.5*[(2) + (3)]
What is the Cooke ratio
Minimum tier 1 + tier 2 capital/ Basel ratio must be 8% of RWA
How is Basel III a stronger basis than Basel II
- Minimum tier 1 capital is 6% of RWA
- Conservation buffer to reduce pro-cyclicality
- Further assets to be disallowed to reduce systemic risk
- Liquidity requirements via LCR and NSFR
What are the two approaches to categorising RWA?
- Standardised approach
- Internal Ratings Based (IRB) approach
Outline the standard approach to calculating RWA
- Under Basel I- most loans were weighted at 100% of nominal with exceptions like nominal/collateral backed loans
- Under Basel II- almost all rating s have a risk weighting category and hence risk weighting
Outline the IRB approach
- Under Basel II- banks can categorise and risk weight assets based on credit rating determined by own IRB model
- Requires thorough credit assessment
- Must be approved by regulator
Whatare the components of the twin peak approach for calculating pillar I capital
- Market consistent approach - SCR
- Basic valuation based on Solvency I- MCR
Outline the SCR under Solvency II
- SCR must be achievable with 99.5% confidence interval over 1 year time horizon
- Being below = regulatory intervention
- Calculated using standard formula or approved internal model
Outline the basis of the standard formula to calculating SCR under Solvency II
- Deterministic with some stochastic elements e.g., for guarantees
- Deals wuth market risk by limiting admissibility of some assets and stress tests
- Deals with credit risk by limiting exposure to individual counterparties
- Deals with uw risk by requiring additional solvency margins
Which standards must internal model meet for Solvency II
- Use test- company must actually use it in risk management and decision-making
- Statistical quality standards- ensures realistic and reliable assumptions
- Calibration standards- ensures output xan be used to properly calculate SCR
- Profit and loss attribution
- Validation standards
- Documentation standards
Outline the basis of the MCR under Solvency I
- 3M Euros + margin on premium/reserve amounts
- MCR must be achievable with 80-90% confidence over 1-year time horizon
- Being below == lose authorisation
