One year ago you bought $100,000 of shares partly funded using a margin loan. The margin loan size was$70,000 and the other $30,000 was your own wealth or 'equity' in the share assets. The interest rate on the margin loan was 7.84% pa. Over the year, the shares produced a dividend yield of 4% pa and a capital gain of 5% pa. What was the total return on your wealth? Ignore taxes, assume that all cash flows (interest payments and dividends) were paid and received at the end of the year, and all rates above are effective annual rates. Hint: Remember that wealth in this context is your equity (E) in the house asset (V = D+E) which is funded by the loan (D) and your deposit or equity (E). The risk-weight on "Margin lending against listed instruments on recognised exchanges" is 20% according to APRA's interpretation of the Basel 3 Accord in 'Prudential Standard APS 112 Capital Adequacy: Standardised Approach to Credit Risk, Attachment A: Risk-weights for on-balance sheet assets'. A bank is considering lending a$100,000 margin loan secured by an ASX-listed stock. How much regulatory capital will the bank require to grant this loan under the Basel 3 Accord? Ignore the capital conservation buffer and the off-balance sheet exposure.

Question 981  margin loan, Basel accord, credit conversion factor

Margin loans secured by listed stock have a Basel III risk weight of 20%.

For margin loans that cannot be immediately cancelled by banks and asked to be repaid, the credit conversion factor (CCF) is 20%.

Suppose you have a stock portfolio worth $500,000, financed by: •$300,000 of your own money; and
• \$200,000 of the bank’s funds in the form of a margin loan which can only be cancelled by the bank after 5 days notice. The margin loan’s maximum LVR is 70%.

How much regulatory capital must the bank hold due to your margin loan? Assume that the bank wishes to pay dividends to its shareholders, so include the 2.5% capital conservation buffer in your calculations.
