FRM Handbook Ch 27: Firmwide Risk Management (Organization and RAROC)

Good risk models fail in bad organizations. Chapter 27’s second half is about structure: who reports to whom, how traders get paid, and how to translate risk into dollars that business lines actually feel.

The old structure and why it broke

Jorion sketches the traditional commercial bank layout. Credit officers approve loans. Treasury trades and hedges. Line management runs operations. Audit reviews everything after the fact.

The fatal flaw: market risk management reported to trading. The people measuring risk worked for the people taking risk. Independence was theoretical. Most advanced institutions have moved to a Chief Risk Officer (CRO) model where market risk, credit risk, and operational risk functions all report to a CRO who sits outside the business lines.

Board and senior management roles

Effective firmwide risk management needs governance, not just models:

• A board subcommittee approves risk limits and policies.
• Senior management implements controls and monitors exposures daily.
• Written documentation exists at every level of the control hierarchy.
• External audit supplements but does not replace internal oversight.

The FRM exam examples in this section are blunt. A trader who processes her own trades can hide mistakes and book size. Price marks should come from independent sources, not from the desk that owns the position.

RAROC: putting risk into the P&L

Risk-adjusted return on capital (RAROC) is the framework that connects risk measurement to business decisions. The basic idea:

$$\text{RAROC} = \frac{\text{After-tax adjusted profit}}{\text{Economic capital}}$$

Adjusted profit subtracts expected losses and a cost of capital charge. Economic capital is the VaR-type buffer assigned to the business unit.

RAROC answers a simple question: is this desk earning enough return for the risk it consumes? A desk with 30% ROE but consuming half the firm’s capital may be a worse deal than a desk with 15% ROE on a small capital base.

Applications include:

• Pricing: Loans and trades priced to cover expected loss plus a return on allocated capital.
• Performance evaluation: Trader bonuses tied to RAROC, not raw P&L.
• Capital allocation: Limited capital directed to highest RAROC activities.
• Portfolio optimization: Business mix adjusted to improve firmwide risk-return.

The chapter is clear that RAROC is only as good as the capital numbers feeding it. Garbage economic capital produces garbage RAROC rankings.

Controlling traders

Compensation

Trader bonuses tied to short-term profits create an option-like payoff. Win big, get rich. Lose, get fired (and often hired elsewhere). The trader is long volatility and has an incentive to take more risk than the firm wants.

Fixes include stock-based compensation, multi-year performance hurdles, and subtracting a capital charge from trading profits before calculating bonuses.

Risk manager pay must not depend on trader performance. Otherwise the risk function becomes a rubber stamp.

Limits

Three types of limits appear in practice:

Stop-loss limits kick in after losses accumulate. They are backward-looking and cannot prevent the first loss. They do stop traders from doubling down to recover.

Exposure limits cap notional or duration. Simple but blind to diversification and market volatility changes. Traders can game them (inverse floaters with 12-year duration inside a five-year note limit).

VaR limits account for diversification and time-varying risk. But traders can move into positions with artificially low model risk. VaR limits work best paired with exposure limits and stress tests.

What stuck with me

Organization chapters can feel like management consulting filler. This one is not. The Barings, SocGen, and Allied Irish stories from Chapter 25 happened partly because risk functions lacked independence and trader incentives rewarded hidden risk.

RAROC is the bridge between the quant side and the business side. Without it, risk management stays a compliance exercise. With it, capital has a price and desks compete for it.
