Exam-day cram sheet

100 exam questions distributed as: Ch 1 · 13Ch 2 · 7Ch 3 · 18Ch 4 · 16Ch 5 · 12Ch 6 · 11Ch 7 · 8Ch 8 · 4Ch 9 · 5Ch 10 · 6 Chapters 3 and 4 (operational and credit risk) carry over a third of the paper between them; chapters 1, 3, 4, 5 and 6 together are about 70 questions.

Ch 1a · Risk basics and drivers

RiskPossible harm: impact × probability
Risk vs uncertaintyQuantifiable vs cannot be quantified
Simple frameworkBoard policy · risk function oversight · business day to day
Operational driversPeople · processes · systems · external events
PESTLEPolitical, Economic, Social, Technological, Legal, Environmental
ESGEnvironmental · Social · Governance
Strategic risk: 2 questionsIs the strategy right? Is it implemented properly?
Financial risksCredit · market · liquidity
Trap: risk is quantifiable; uncertainty is not. Do not use them as synonyms.

Ch 1b · Terminology

Risk appetiteType and amount of risk a firm will accept (tolerance)
Top-downBoard and senior management: capital, scenarios
Bottom-upLine management: acceptable occurrences, KRIs
Inherent / gross riskBefore mitigating controls
Residual / net riskAfter controls; may not be zero
Conduct riskFirm's behaviour causes poor customer outcomes
Stress testOne input factor at a time
Scenario analysisRealistic combinations, often past extremes
Trap: gross = before controls, net = after controls. Mitigation reduces impact, likelihood or both.

Ch 1c · BIS risks, systemic risk, new areas

BIS risk areasOperational · credit · market and asset liquidity · funding liquidity · interest rate
Asset liquidity riskCannot unwind a position near market value
Funding liquidity riskCannot get funds when obligations fall due
InterconnectednessInteractions between risks are non-linear
Systemic risk / contagionFailure spreads to threaten the whole system
Sovereign default riskState guarantees banks but cannot honour it
Recovery and resolution plansCredible recovery + orderly failure
GDPR fine€20m or up to 4% of global turnover, whichever is greater
Crypto custodyAbout private keys; hot online, cold offline
Trap: asset liquidity is about selling assets; funding liquidity is about the liability side.

Ch 2a · BIS, Basel Committee, Core Principles

BISBank for central banks · 1930 · Basel · guidelines not law
BCBSStandard-setter for bank prudential regulation
Bank run fix and side effectDeposit insurance + lender of last resort → moral hazard → minimum capital
Economic vs regulatory capitalOwn estimate vs mandatory level
Accord risksCredit · market · operational
Basel III/IV additionsCountercyclical buffer · leverage ratio · NSFR and LCR
Core Principles29 · 1-13 supervisors · 14-29 banks · 6 preconditions
Trap: the leverage ratio has no risk weighting. BIS guidelines only bite once national regulators implement them.

Ch 2b · The three pillars

Pillar 1Capital > 8% × (credit + market + operational)
Pillar 2Supervisory review
ICAAP / ICARABanks / investment firms
Pillar 3Market discipline · public disclosure
Use testIs risk-based decision-making embedded?
ConcordatConsolidated home supervision · home and host consent
Trap: Pillar 1 = minimum capital, Pillar 2 = review, Pillar 3 = disclosure. Do not rotate them.

Ch 2c · UK regulation

Statutory vs principles-basedSpecific rules (US SEC) vs general expected behaviours (UK)
FCA objectivesProtect consumers · protect markets · promote competition
FCA vs PRAConduct vs capital-focused
Principles for Businesses11 (first 5 indirect, next 5 direct, 1 regulators)
Supervision intensityImpact and probability scores
Breaking the law: harmsReputation · authorisation · fines · liability · staff
Trap: principles-based means outcomes and judgement; statutory means detailed rules.

Ch 3a · Operational risk: definition and policy (the heaviest chapter)

DefinitionLoss from failed processes, people, systems or external events; includes legal, excludes reputation
7 Basel event typesInternal fraud · external fraud · employment practices · clients/products · physical assets · business disruption · execution/delivery
Policy: 4 areasKey officers · roles · segregation of duties · cross-functional
BaringsFailed segregation of duties
Framework stagesPolicy → identify → assess → manage → monitor → report → policy
Trigger vs limitTrigger = amber; limit = red
4 causesPeople · process · system · external event
Trap: operational risk includes legal risk but excludes reputation risk. Barings is a segregation-of-duties story.

Ch 3b · Operational risk: assess and respond

Risk scoreLikelihood × impact
Scenario analysisTop-down, risk combinations
Bottom-upProcess-level risks and controls rolled up
KRIsForward-looking, likelihood drivers; amber and red
Expected lossesBudget / revenues; within appetite
Unexpected lossesLow frequency, high cost: capital or insurance
ConstraintsData · cultural · resource and cost · indicator
4 responsesTransfer · avoid · mitigate · accept
Control typesPreventative (stop) · detective (find)
BCP vs DRPremises and people vs IT and infrastructure
GDPRUp to €20m or 4% of global revenue, whichever is higher
Trap: outsourcing does not remove the risk; it turns it into managing the quality of the outsourced process.

Ch 4a · Credit risk: identify and measure

Credit riskLoss from counterparty or issuer failing to meet obligations (obligor)
Counterparty vs issuer riskBroker fails to deliver vs bond issuer defaults
Settlement vs pre-settlementOne side pays, other does not vs default before settlement (e.g. swap)
Systemic riskNorthern Rock spread; Barings (1995) did not
Credit exposureCurrent + potential future exposure
Credit risk premiumBorrowing rate minus default-free rate
Grades (S&P style)Investment AAA to BBB · speculative BB to D
UK-nominated agenciesFitch · Moody's · S&P · DBRS
Trap: ratings measure credit quality only, not market or liquidity risk, and they are opinions.

Ch 4b · Expected loss and credit terms

Expected lossEL = PD × EAD × LGD
Recovery rateRR = 100% − LGD
LGD example$500m loan, $300m loss = 60%
EADExposure at default; includes expected further drawdowns
Credit eventBankruptcy, insolvency, missed payment, even a downgrade
Wrong way riskExposure adversely correlated with counterparty credit quality
Non-performingUsually 90 days late (before that: past due)
Credit limitsBorrower · counterparty · connected groups; binding
Trap: RR and LGD are two sides of one coin. A counterparty's own shares taken as collateral are wrong way risk.

Ch 4c · Mitigation, concentration, VaR

NettingLegally enforceable offset: £4m and £6m replacement cost fall to £2m and £3m
CollateralUnilateral · bilateral · netted; marked to market
CDSBuyer pays fee; seller pays on credit event on reference entity
SecuritisationOriginator, issuer (SPV), rated bonds
CCPClearing house counterparty to both sides; boosts netting
Haircut example$100m shares lent, 3% haircut: $103m collateral
Basel rolesBoard approves strategy (review at least annually); senior management implements
HHISum of squared shares: 50/50 = 50%; 2/98 = 96.08%
Credit VaR$5m at 95% = 5% chance of losing more
Trap: HHI ignores credit quality (AAA and B count the same). A CDS buyer swaps credit risk for counterparty risk on the seller.

Ch 5a · Market risk types

Market riskLoss from changes in value of financial instruments
Volatility riskUnusually uncertain prices; options dearer
Market liquidity riskCannot trade or get a price: lack of supply, demand or market makers
Basis riskHedge is similar, not identical
Interest rate riskBond prices move inversely to rates; long bonds move more
Commodity riskConcentrated supply, storage costs, price jumps
Currency exampleUS assets +10%, dollar −8%: about 2% for the investor
Trap: basis risk = imperfect hedge. Short bonds (under 3 years) move less than long bonds (over 10 years).

Ch 5b · Managing market risk

HedgingOffsetting position, e.g. buy a put option; trade-off with cost
Market risk limitStop-loss limit, VaR or absolute amount
DiversificationPortfolio SD below weighted average of components
Electronic trading / HFTSmall position limits, fast liquidation, low risk per trade
Effective functionIndependent, escalation, VaR plus stress and scenarios, daily P&L
VaRMaximum loss at a confidence over a period
Back testingActual daily exposure vs predicted VaR, daily
Three VaR approachesHistorical simulation · parametric · Monte Carlo
Stress vs scenarioOne variable at a time vs several together
Trap: VaR does not say how bad the tail is (a $10m/95% VaR is silent on the other 5 days). Parametric assumes normality; Monte Carlo handles non-normal instruments such as options.

Ch 5c · Statistics toolkit

MeanSum ÷ n (7-12% funds: 9.5%)
MedianMiddle value; even count = average of middle two (12.5)
ModeMost frequent ($100k example)
Range / IQRHigh minus low (13 − 2 = 11) / Q3 − Q1
Quartile deviation(Q3 − Q1) ÷ 2 = (83 − 60) ÷ 2 = 11.5
Variance / SDMean 7.4%; squared gaps 86.4 ÷ 10 = 8.64; SD = square root
Sample SDDivide by n − 1
Normal distribution68.26% / 95.5% / 99.75% within 1 / 2 / 3 SD
Correlation−1 to +1; only +1 removes all diversification benefit
Beta0 = uncorrelated to market; negative = inverse
Trap: mean is pulled by outliers, median is not (skewed incomes). Fat tails mean a normal assumption understates extreme moves.

Ch 6a · Returns and time value

Nominal returnNot adjusted for inflation
Real return (exact)(1 + real)(1 + inflation) = 1 + nominal: 12% and 8% gives 3.7%
Total returnIncome + capital gains
Holding period return(Income + gain) ÷ initial value
Future valueS = X(1 + r)ⁿ: $10,000, 10%, 4 years = $14,641
Present valueX = S ÷ (1 + r)ⁿ: $14,641 → $10,000
1980-2011 returnsEquities ~7.8% · corporate bonds ~6.1% · T-bills ~1.6%
Equity risk factorsLiquidity · growth · volatility · strategic risk of issuer
Seven investment risksCurrency · interest rate · issuer · equity · commodity · property · fund liquidity
Trap: divide (1.12 ÷ 1.08) for the exact real rate; subtracting gives only the 4% approximation.

Ch 6b · Ratios and portfolio risk

Two-thirds rule9% mean, 4% SD: 5% to 13% two-thirds of the time
BetaVolatility vs market; 1 = in line; 36 monthly points
AlphaOutperformance vs benchmark; can hide fees
Sharpe ratio(Return − risk-free) ÷ standard deviation
Information ratioMean excess return ÷ tracking error
Tracking errorEx post for reporting · ex ante for control
Non-systematic riskDiversifiable with 15 to 20+ low-correlated stocks
Diversify vs hedgeUncorrelated vs negatively correlated
Illiquid assetsVenture capital · private equity · property
Short sellingBorrowed stock; loss unlimited
Trap: Sharpe compares to the risk-free rate; the information ratio compares to the benchmark. Systematic risk cannot be diversified away.

Ch 7a · Identifying and measuring liquidity risk

Liquidity riskNot enough cash: insolvency, dear borrowing, fire sales, penalties
Northern RockLong mortgages funded short; 9 Aug 2007 freeze; nationalised
Maturity ladderInflows vs outflows by date (day one: 180 − 100 = 80)
Asset vs funding liquiditySell or pledge assets vs liability-side funding
Gap analysisNet flow per bracket; ignores credit risk, cannot handle options
Four asset measuresBid-offer spread · depth · immediacy · resilience
ResilienceSpeed prices recover after a large trade
Spread ratioSpread ÷ mid-price; smaller = more liquid
Trap: funding liquidity concerns liabilities; asset liquidity concerns selling or pledging assets. Ladder timing: inflows later, outflows earlier.

Ch 7b · Managing liquidity risk

Management processContractual → normal behaviour → stress → compare to appetite
UK regimeILAA
Fund toolsGates limit redemptions · side pockets block them
Three scenariosGoing concern · bank-specific · general market crisis
Day-one scenario result+80 · (40) · (90)
LaRHistoric funding distribution at confidence levels
Funding sourcesWholesale · securitisation · retail deposits · central bank
Netting exampleWith: $16m inflow · without: $20m outflow
Market dislocationMarkets do not clear at any price; deflation risk
Trap: in a dislocation, cutting rates does not make banks lend. In the netting example, netting turns a $40m asset into a $16m inflow.

Ch 8 · Model risk

Model riskAdverse outcomes from incorrect or misused models
Two causesFundamental errors · misuse
Risk typeAn operational risk
LTCMConvergence trades → drift → lost $4.4bn of $4.7bn (1998)
Op risk scenario modelFrequency, typical loss, extreme loss; workshop = 1 in 20 (95%)
Poisson vs lognormalHow often vs how bad
Capital levels1 in 200 = 99.5% · 1 in 1,000 = 99.9%
Historical simulatione.g. 500 days; 5th percentile for 95%
GovernanceBoard owns; senior management executes; internal audit assesses
Back-testingCompare output with reality once it catches up
Trap: a plain spreadsheet calculation is not a model. Operational losses are fat-tailed, not normal.

Ch 9 · Governance and culture

Corporate governanceRun in shareholders' long-term interest
Risk committeeRatify policy · monitor · turn appetite into limits
Appetite approvalCommittee recommends · board approves annually
Committee chairNon-executive director
CRO powersSet business limits, approve excesses within board limits
1st lineBusiness owns risk
2nd lineRisk and compliance: support and challenge
3rd lineInternal audit: independent assurance
BIS Principle 12 (2015)Disclosure and transparency: 6 topics
Moral hazardBehaving differently when shielded from consequences
Trap: compliance is second line, not third. Risk managers must not take risks or advise which to take.

Ch 10 · Enterprise risk management

ERMAll risks, and how they relate to each other
Regulatory driverBasel Pillar 2 (ICAAP)
Pillar 2 stepsDefine exposure · stress · compare to capital
Cultural challengesExecutive sponsor · common language · merging teams
Escalation matrixIncident types vs who is alerted at each severity
Aggregation challengesMeasurement · timescales · combining data
VaR horizonsMarket days · credit and liquidity weeks/months · operational months/years
Client riskNo compensation, but fees fall (earnings at risk)
ESGIdentify · evaluate · act; horizon at least 10 years
GRCHarmonised risk management; more than software
Trap: internal audit audits the ERM framework independently; it does not supply the risk data.
