Capital(Equity) = Shareholders funds + past retained profits Capital acts as like a deductible or excess on an insurance policy It is a financial cushion for the bank Banks equity represents the amount the banks assets may fall, such that the depositors could in principle still sell off the remaining good assets and obtain the full face value of their deposits

© K.Cuthbertson and D.Nitzsche Basle (1988) Accord on Credit Risk
© K.Cuthbertson and D.Nitzsche TOPICS BASLE (1988) ACCORD Risk Weights Equity-Assets Ratio/ Risk Adjusted Asset Ratio Bank Capital: Tier I and II
© K.Cuthbertson and D.Nitzsche Basle (1988) Risk Weights Risk Weights (0 ot 100%) given to all types of counterparty (e.g. OECD governments, corporates etc) and asset (e.g. bank loans, securities held) Equity capital required for credit risk is set at a min. = 8% of value of (risk weighted) total assets
© K.Cuthbertson and D.Nitzsche RELATIVE RISK WEIGHTS Zero % 20% 50% 100% cash and gold bullion claims on OECD central banks claims on development banks claims on other OECD banks mortgages on residential property claims on private sector (eg. bank loans) claims on governments outside OECD
© K.Cuthbertson and D.Nitzsche RISK-ADJUSTED ASSETS RATIO, RAR Risk Weights of w i= 10, 20 or 50 and 100% A i = market value of banks assets Risk Weighted Total Assets  RWTA = (w i /100) A i Risk Adjusted Assets Ratio, RAR  RAR = (Equity Capital /RWTA) x 100 Basle Accord requires RAR to be greater than 8% The more Equity capital E, you hold (as proportion of total assets), the bigger cushion against potential losses
© K.Cuthbertson and D.Nitzsche SOLVENCY AND THE BASLE RATIO Solvency requires: Tot Assets(TA)- Bad Debts(BD) >Deposits (D) TA - BD > D But balance sheet gives TA=D +E Hence solvency requires: E > BD or (E/TA) > (BD/TA) (BD/TA)= proportion of Bad Debts (g) (E/TA) = Equity assets ratio
© K.Cuthbertson and D.Nitzsche SOLVENCY AND THE BASLE RATIO Solvency requires: The equity-assets ratio, EAR (= E/TA), exceeds the proportion of bad debts, g. Risk Adjusted Assets Ratio RAR Replace equity-assets ratio with RAR Solvency requires: RAR > g (latter set at 8% by Basle) g = proportion of bad debts
