Prepayment risk is the option mortgage borrowers hold to repay early, typically by refinancing when rates fall.
How is a plain vanilla fixed-for-floating interest rate swap priced at inception?
Plain vanilla IRS priced so fixed leg PV equals floating leg PV at inception. Float PV = N(1-D(T)). Swap rate K = float PV / annuity factor...
What is SA-CVA (Standardized Approach CVA) under Basel III?
SA-CVA is the standardized approach for calculating regulatory CVA capital, finalized in the Basel III reform package. Banks must have supervisory approval; otherwise they default to BA-CVA. Six risk buckets: IR, FX, credit spread, equity, commodity, CCR spread...
What is intraday liquidity risk and how do banks monitor it?

What's the difference between a credit curve steepener and flattener trade?

Default risk vs downgrade risk — how should I think about them separately?
Default risk is actual payment failure with recovery; downgrade risk is rating deterioration causing spread widening without default. Use a transition matrix: a BBB bond might have 13% downgrade probability and 0.5% default probability in one year.
What is process verification in model validation?
Process verification tests implementation correctness, data pipelines, model environment controls, output integrity, and user overrides. Complements conceptual and outcomes review.
How do I interpret a simple linear regression output for CFA Level I?
Simple regression models Y = b₀ + b₁X + ε. The slope (b₁) is the change in Y per unit change in X, the intercept (b₀) is the Y value when X is zero, and R² measures the proportion of Y's variation explained by X.
How do duration and convexity measure interest rate risk? I need an intuitive explanation.
Duration and convexity together give you a complete picture of how a bond's price responds to interest rate changes. Think of duration as the first-order effect and convexity as the second-order correction.
What's the difference between cash-settled and physically-settled swaptions?
Physical = enter actual swap. Cash = lump-sum PV. Cash-settled PVBP uses IRR discounting, creating small valuation basis vs physical.

How does a put ratio spread target moderate downside moves?
A put ratio spread is long fewer puts at a higher strike and short more puts at a lower strike, targeting moderate declines with defined profit peak.

Private foundations offer maximum control and legacy for family philanthropy but require 5% minimum distributions, 990-PF filing, and self-dealing compliance.
What is Market Value Added (MVA) and how does it relate to EVA?
Market Value Added (MVA) equals the market value of capital minus the book value of invested capital.
How does basis risk arise when a corporate treasurer hedges floating-rate debt with FRAs?
