What are the three main VaR calculation methods and when should each be used?
Value at Risk can be calculated using three methods: parametric (variance-covariance), historical simulation, and Monte Carlo simulation. Each has distinct strengths — parametric is fast for linear portfolios, historical simulation captures fat tails, and Monte Carlo handles non-linear instruments like options.
Parametric VaR vs. Historical Simulation VaR — when does each method fail?
Excellent question — understanding when VaR methods break down is arguably more important than knowing the formulas, and GARP loves testing this on the exam. Parametric VaR fails with non-normal returns, non-linear positions, and unstable correlations. Historical simulation suffers from ghost effects, backward-looking bias, and limited tail data.
What are the four axioms of a coherent risk measure, and how does VaR violate subadditivity?
A coherent risk measure must satisfy monotonicity, subadditivity, positive homogeneity, and translation invariance. VaR violates subadditivity because combining independent credit positions can increase measured VaR, contradicting the diversification principle.
What is the multi-curve framework, and why did the 2008 crisis force a separation between discounting and forward projection curves?
The multi-curve framework uses separate curves for discounting (OIS/risk-free) and forward rate projection (tenor-specific). The 2008 crisis forced this separation when LIBOR-OIS spreads widened to 350+ basis points, proving that LIBOR was not risk-free.
How do cliquet options accumulate returns through their reset mechanism, and why are they popular in structured products?
Cliquet options are a series of forward-starting options that reset the strike to the current spot at each period. Returns are capped and floored per period, then accumulated, making them popular in structured products that offer principal protection with equity participation.
What are the trade reporting requirements for OTC derivatives under Dodd-Frank and EMIR, and what role do swap data repositories play?
Trade reporting mandates require all OTC derivative transactions to be reported to registered repositories. Under Dodd-Frank, reporting is one-sided based on a hierarchy, while EMIR requires dual-sided reporting by both counterparties within T+1.
How does central clearing of OTC derivatives work, and what role does a CCP play in reducing counterparty risk?
Central clearing interposes a CCP between the original buyer and seller of an OTC derivative. The CCP manages risk through initial margin, variation margin, and a structured default waterfall. While clearing reduces bilateral counterparty risk, it concentrates systemic risk in the CCP.
How do heating degree days and cooling degree days work in weather derivatives?
Weather derivatives allow businesses to hedge revenue exposure to temperature fluctuations. Heating Degree Days (HDD) measure cold relative to a 65°F baseline, while Cooling Degree Days (CDD) measure heat above it. Contracts typically cover a cumulative period.
How does Black's model for options on futures differ from the standard Black-Scholes model?
Black's model (1976) is essentially Black-Scholes adapted for options where the underlying is a futures contract rather than a spot asset. The key simplification is that the futures price already incorporates the cost of carry.
How do AIC and BIC work for comparing risk models, and when would they give different recommendations?
AIC and BIC both balance goodness-of-fit against model complexity, but BIC penalizes additional parameters more heavily, especially for large samples. AIC tends to prefer slightly more complex models while BIC favors parsimony.
What is asset-backed commercial paper (ABCP) and what liquidity risks do ABCP conduits face?
Asset-backed commercial paper (ABCP) is short-term debt typically maturing in 30-90 days, issued by a special purpose vehicle called a conduit and backed by longer-term financial assets. The fundamental risk lies in the maturity transformation between short-term funding and long-term assets.
What is volatility clustering and how do you test for ARCH effects in financial returns?
Volatility clustering means large price moves tend to follow large moves. The Engle LM test detects ARCH effects by regressing squared residuals on their lags — a significant test statistic means volatility is time-varying.
How do cross-currency swaps actually work, and why is the notional exchanged unlike regular interest rate swaps?
Cross-currency swaps are fundamentally different from plain IRS because they involve two different currencies, so netting the notional makes no sense. At inception, parties exchange notionals at the spot rate and re-exchange them at maturity at the original rate.
What is cointegration and how is it used in pairs trading?
Cointegration means two non-stationary series have a stationary linear combination — they share a long-term equilibrium. Unlike correlation (short-term co-movement), cointegration implies the spread is mean-reverting, enabling pairs trading strategies.
How are credit-linked notes (CLNs) structured and who benefits from them?
A credit-linked note (CLN) is a funded credit derivative where the investor buys a bond with an embedded CDS. The investor receives enhanced coupons but absorbs credit losses if the reference entity defaults. CLNs reduce counterparty risk compared to unfunded CDS.
What is model calibration in risk management and how do you avoid overfitting?
Model calibration adjusts parameters to match current market data, while estimation fits to historical data. Overfitting occurs when the model memorizes noise rather than capturing real patterns, leading to poor out-of-sample performance. Key defenses include parsimony, cross-validation, and economic constraints.
How do catastrophe bonds and insurance derivatives transfer risk to capital markets?
Catastrophe bonds allow insurers to transfer tail risk to capital markets through an SPV structure. Investors receive high coupons (SOFR + 700-1200bps) in exchange for bearing the risk of losing principal if a qualifying catastrophic event occurs.
How does a repurchase agreement (repo) transaction work step by step, and what are the risks involved?
A repurchase agreement is economically a collateralized loan structured as a sale and repurchase of securities. The cash borrower sells bonds to the lender at a haircut, receives cash, and repurchases the bonds at maturity plus repo interest. Key risks include counterparty, collateral, rollover, and fire-sale risk.
How do duration and convexity work together to estimate bond price changes, and when does duration alone fail?
Duration provides a linear approximation of bond price sensitivity to yield changes, while convexity adds the curvature correction. For yield changes beyond 50 bps, duration alone significantly overestimates price declines and underestimates price gains. The full formula is: change in price ≈ -duration × yield change + half × convexity × yield change squared.
What are the core components of an Enterprise Risk Management (ERM) framework, and how does it differ from siloed risk management?
This is a foundational topic that sets the stage for everything else in the FRM curriculum. Before the 2008 crisis, many institutions managed risks in silos — credit, market, and operational risk teams worked independently. ERM exists to aggregate and correlate risks across the entire enterprise, preventing blind spots where interconnected exposures fall through the cracks.
