  1. The Basel III Proposals, May 2010 Adrian Blundell-Wignall Special Advisor to the OECD Secretary General for Financial Markets

  2. Fig. 1: Basel I & Basel II

  3. Fig 2: Problems With Basel II • Portfolio invariance. • Single global risk factor. • Financial system “promises” are not treated equally—regulatory arbitrage facilitated by “complete markets” in credit (the CDS market particularly). • Pro-cyclicality. • Subjective inputs. • Unclear and inconsistent definitions.

  9. Fig 8: Basel III Proposed Capital Reforms • Quality, consistency & transparency of the capital base. • Enhance risk coverage. • Introduce a leverage ratio. • Deal with Pro-cyclicality. • Address systemic risk & interconnectedness.

  10. Fig 9: Basel III Best Points • Leverage ratio notion. • Dynamic provisioning on expected loss. • Capital buffer to ensure minima are not violated in a crisis. • Better capital definitions. • Some improvement in subjective inputs likely.

  11. Fig 10: Basel III Not Dealt With • The main issue has always been the lack of capital. Where the leverage ratio will be set. • The RWA approach & a leverage ratio wont work well together. • Promises will still be treated differently depending on where they sit, so regulatory arbitrage will continue. • The framework still relies on portfolio invariance & a single global risk factor+ pillar 2 filling the holes.

  12. Fig. 11: Not Enough Capital

  13. Fig 12: Basel III Not Dealt With • Min.CAP(RWA)=0.08*{12.5(OR+MR) + SUM[w(i)A(i)]} • Min.CAP(LR)=βSUM[A(i)] • Min.CAP(RWA)≤ Min.CAP(LR) NB. Setting ‘maximum’ capital requirements via the LR and leading to distortions

  14. Fig 13: The Liquidity Proposals • The liquidity coverage ratio LCR, 30 day focus. • The Net Stable Funding ratio, focusing on the liquidity characteristics of liability and asset structure. • Other monitoring.

  15. Fig 14: Problems with the Liquidity Proposals • Solvent banks should manage their own liquidity with the bank payment system process & central banks having a key role—cause & effect in the crisis was from insolvency fear to liquidity. • Bias to government bonds – crowding out lending to the private sector implications. • Not practical—stable versus unstable funding (its all unstable in a crisis). • Lowers returns causing banks to take on more risk.

  16. Fig 15: Conclusions • There are no stable risk “buckets” for weighting assets when promises in the financial system are not treated equally—risk easily transformed in complete markets for credit. • Leverage ratio to centre stage. • Diversification issues need to be dealt with in pillar 1 (quadratic capital penalty for deviations from benchmark). • Treating promises equally has implications for the structure of regulatory authorities. • And how to treat the shadow banking system.
