and renew with most updated rate
- Collateral
- Payment netting
- Minimum credit standards (but there are SPV
and EDPC – Enhanced derivatives products companies
- Derivative to transfer risk to others
- Total return swap:
- Credit spread option
- Credit spread forward
- Credit default swap
Risk-adjusted
return on invested capital
(RAROC): expected return on risk (e.g. VAR)
Return
over maximum drawdown (RoMAD)
– maximum of drawdown in total period.
Drawdown: peak-to-trough decline during a specific
measured period
Sortino
ratio = (return –
MAR)/downside risk
MAR – minimum
acceptable return, downside sigma is reference to MAR
Setting
Capital Requirements:
Nominal position
limits (notional position limits, monetary position limits) – can be exceeded
by using derivatives
VAR-based limits –
total VAR may be overestimated
Maximum loss limit
Internal capital
requirement and regulatory capital requirement
