LE Paper 7 · Topic 6
Paper 7 tests this topic mostly through short scenarios: a loss is described and you name the risk, the technique being used or the number behind it. Learn the four risk treatments, why diversification removes only specific risk, and the textbook and Basel definitions of credit, settlement, market, basis, liquidity, operational and other risks, so you can classify a scenario in seconds. Then learn the four-step process (identify, measure, manage, monitor) and the systems Hong Kong's regulators and market operators use to contain financial risk.

Risk is the uncertainty of future outcomes: the possibility that the actual return differs from the expected return, above or below it. It is measured by the dispersion of possible returns around the expected return, usually the variance or its square root, the standard deviation (standard portfolio theory). A loss-only view is downside risk, one part of the picture.
Expected return is the probability-weighted average of the possible returns: E(R) = Σ(probability × return). Investors are assumed to be risk-averse: between two investments with the same expected return they prefer the one with the lower standard deviation, and they take on more risk only for a higher expected return. The extra expected return over the risk-free rate is the risk premium.
| Economy | Probability | Return | Probability × return |
|---|---|---|---|
| Boom | 0.3 | 18% | 5.4% |
| Normal | 0.5 | 8% | 4.0% |
| Recession | 0.2 | −10% | −2.0% |
| Expected return | 1.0 | 7.4% |
Trap: taking the simple average of the outcomes (5.33% here) or the most likely outcome (8%). Weight every outcome by its probability, and keep the minus sign on losses.

Takeaway: Risk is the spread of outcomes around the expected return; expected return is the probability-weighted average.
Once a risk is identified, a firm chooses one of four treatments (standard risk management framework). The choice depends on the size of the possible loss, its likelihood, the cost of treatment and the firm's risk appetite.
| Technique | What it does | Examples |
|---|---|---|
| Avoid | Do not start, or stop, the activity that creates the risk | Closing a margin lending business; refusing a product the firm cannot value |
| Reduce | Keep the activity but cut the likelihood or size of loss | Position and credit limits; collateral; maker-checker controls; diversification; hedging part of a position |
| Transfer | Pass the financial consequence to another party, usually for a premium | Insurance; buying credit default swap protection; selling loans through securitisation |
| Accept (retain) | Bear the risk knowingly, budgeting for losses | Small, frequent errors where controls would cost more than the expected loss; an internal self-insurance fund paid from the firm's own profits |
Transfer creates a new exposure: the insurer or protection seller must be able to pay, so transfer swaps one risk for a credit risk on that party.
Trap: calling insurance a reduction technique, a position limit a transfer, or self-insurance a transfer. Ask who bears the loss afterwards: if it is still the firm, the technique is reduction or acceptance.
Takeaway: Avoid (stop it), reduce (shrink it), transfer (someone else pays), accept (budget for it).
