Why do mortgage-backed securities exhibit negative convexity and what does that mean for investors?
Negative convexity means that as rates fall, MBS prices rise less than expected because homeowners refinance and prepay their mortgages. The investor's upside is capped while the downside from rising rates is fully exposed, creating an asymmetric return profile.
What are the three main sources of model risk in VaR, and how can each one cause VaR to be wrong?
Model risk in VaR refers to the possibility that the VaR estimate is inaccurate because of flaws in how it is built, calibrated, or used. The three primary sources are incorrect model specification, incorrect parameter estimation, and implementation errors.
What is trade compression and why has it become so important in OTC derivatives markets?
Trade compression is the process of terminating redundant or offsetting derivatives trades and replacing them with a smaller number of trades that maintain the same net risk profile. It reduces gross notional, operational complexity, and capital requirements.
What active strategies do commodity hedge funds use to generate alpha?
Active commodity managers generate alpha through several distinct strategies, each exploiting specific inefficiencies that passive indices ignore...
How are catastrophe reinsurance layers structured for a hurricane-exposed insurer?
Cat towers stack layers by return period, with pricing declining higher in the tower but coverage protecting tail capital.
How does a callable swap work and why would an issuer pay for cancellation rights?
Callable swap = vanilla IRS + embedded Bermudan receiver swaption owned by fixed payer. Peakstone pays 20bp extra fixed for right to cancel after year 5, matching callable bond...
How do you hedge a portfolio using delta, gamma, and vega together?
Multi-Greek hedging requires one instrument per Greek beyond delta. Hedge gamma and vega first using options (solving a system of equations), then hedge the resulting delta with the underlying. The order matters because adding options changes delta.
What are the key differences between CAPM and APT, and when would you use one over the other?
CAPM and APT are both equilibrium asset pricing models, but they differ fundamentally in their assumptions, number of risk factors, and practical applications. CAPM uses a single market factor with strong assumptions, while APT uses multiple factors with weaker no-arbitrage assumptions.
What is the history of the DJ-UBS commodity index and how did it become BCOM?
The Dow Jones-UBS Commodity Index (DJ-UBS) is the direct predecessor to today's Bloomberg Commodity Index (BCOM). The rebranding occurred in July 2014 when Bloomberg LP acquired the UBS interest...
How does excess of loss reinsurance differ from quota share?
XoL is non-proportional, paying only above retention — efficient for severity and cat relief while preserving attritional margins.
How do I determine moneyness for payer versus receiver swaptions?
Payer swaption: ITM when forward swap rate > strike. Receiver swaption: ITM when forward < strike. Payers love rate rises, receivers love rate falls...
What is RAROC and how do banks use it for performance measurement and capital allocation?
RAROC evaluates the return a business line generates relative to its economic capital. Unlike ROE, which uses accounting equity, RAROC uses a risk-based capital measure. A business line creates value only when its RAROC exceeds the hurdle rate (cost of equity).
What are the three types of multifactor models and how do they differ?
Multifactor models explain asset returns using multiple systematic risk factors. The three types — macroeconomic, fundamental, and statistical — differ in how factors are identified: from economic variables, company attributes, or statistical extraction from return data.
How does the Bloomberg Commodity Index (BCOM) differ from the GSCI?
The Bloomberg Commodity Index (BCOM), formerly Dow Jones-UBS Commodity Index, uses liquidity-plus-production weighting combined with strict diversification caps...
How does quota share reinsurance work and when is it used?
Quota share cedes a fixed percentage of every risk in a portfolio, returning a ceding commission and sharing losses pro-rata.
What is a blended rate swaption and when would a corporate treasurer use one?
Blended rate swaption gives exercise over a window, not a single date. Tradewind locks 4.65% across a 6-18 month bond issuance window for $1.3M premium on $200M notional...
How do you price a bond using a binomial interest rate tree?
Binomial interest rate trees price bonds by modeling the possible evolution of short-term interest rates and working backward to determine present value. For callable bonds, at each node you take the minimum of the calculated value and the call price.
How is the S&P GSCI commodity index constructed?
The S&P Goldman Sachs Commodity Index (GSCI) is a world-production-weighted index covering 24 commodities across energy, metals, agriculture, and livestock...
How are property and casualty insurance risks different from life risks?
P&C risks are premium, reserve, catastrophe, and latent liability — driven by short-tail volatility and correlated event exposure.
How is the unwind or termination value of a swap calculated?
Termination value = current MTM. Emberline's 10Y receive-fixed IRS at 3.95% with 6Y remaining and current 4.42% rate has negative $3.72M MTM — pays counterparty to exit...
