The response sketches a possible connection between credit availability and equity markets through interest rates and central bank policy. It describes commercial lending rates as linked to broader rates, and central banks as adjusting policy in response to…
The document compares two ways to discount future coupons when solving iteratively for a bond yield or floating-rate note discount margin. One discounts cash flows using a zero rate to each payment date; the other compounds period by period using accrual…
The document derives the value of a floating-rate bond by pricing its coupon payments and principal as cash flows that can be replicated with zero-coupon bonds. It defines each LIBOR coupon from the bond price over its accrual period, then shows that the…
The document explains a proposed way to divide non-maturity deposits into core and non-core balances for interest rate risk modeling. It distinguishes stable balances, which tend to remain on account, from core balances, which are also unlikely to reprice…
The document raises a conceptual question about how bond maturity and yield relate to convexity. It presents two proposed statements: that longer maturity leads to higher convexity, and that lower yield leads to higher convexity. The author reasons that…
The document explains how fitted yield curves relate to observed coupon bond data and to zero-coupon rates. Early curves were drawn through individual bond yields, often emphasizing bonds trading near par because coupon differences make yields harder to…
The document compares simple functional fits to a set of bond yield observations: a linear fit against square-root maturity, a linear fit against log maturity, and a quadratic fit. The author describes visual shortcomings in each curve and asks whether any…
The document clarifies that Macaulay duration is related to, but is not itself, the slope of a bond’s price-yield curve. For a bond priced from discounted cash flows, the slope depends on both price and duration; under the convention shown, it equals…
The document shows how to express a stochastic interest rate with deterministic time-varying drift as the sum of a random component and a deterministic component. The rate follows a mean-reverting diffusion with constant mean-reversion and volatility…
The thread examines whether VaR equivalent volatility (VEV), a PRIIPs key information document measure, can be negative. It gives the formula used to convert a VaR measure into VEV and argues that if VaR is interpreted as the fraction of the amount invested…
The document explains why the value at time t of a unit payment due at time T is expressed using the accumulated short rate from t to T. It defines the growth of a unit investment from time zero to each date, then obtains the discount factor by dividing…
The document develops a pricing route for a European call on a zero-coupon bond in the Vasicek short-rate model. The bond price is represented as an exponential-affine function of the current short rate, and the option payoff is split into a bond-value term…
The document discusses whether a well-known book on Treasury bond basis remains useful for learning US Treasury bond and note futures. The respondent considers it a strong reference for the market’s history and analytical methods, despite its publication…
The document shows an attempt to reproduce a Federal Reserve rate-hike probability displayed by a futures-market calculator. It uses two monthly fed funds futures prices to infer the implied average rates for the current and following months, then solves for…
The document raises an accounting question about Federal Reserve overnight and term repo operations during periods when dealers face year-end balance-sheet constraints. It asks whether a dealer’s repo with the Fed, in which the dealer receives cash and posts…
The document addresses why a normal-model swaption price may appear too high when compared with a lognormal Black-model price. The response identifies a likely source of the mismatch: normal and lognormal volatilities use different scales and cannot be…
The document explains how to combine the interest-rate sensitivity of discounted insurance claims and recoveries. It treats the cashflows as a portfolio and uses value-weighted durations, with recoveries represented by a negative value. The resulting net…
The document presents a fixed-rate bond pricing discrepancy: QuantLib returns a price just below par when the stated coupon and yield are equal, while spreadsheet and market tools reportedly return par. The accepted response supplies a matching setup using a…
This document outlines trade-offs among three interest-rate option model families. It describes SABR as a formula-based approach used for European swaptions and some foreign-exchange vanilla options, with efficient computation and established hedging…
The document clarifies two common interest-rate sensitivity scenarios. A parallel shift bumps all curve inputs together, producing a duration-like measure; a key-rate shift bumps one market quote at a time while holding the others fixed, producing…
The document considers whether a financial institution could use a short-dated options position to reduce its reported exposure to a prescribed regulatory yield-curve shock. Its example is a strangle whose strike range corresponds to part of the shock,…
The document addresses a calibration step in the one-factor Hull–White interest-rate model: finding the critical rate that satisfies the equation used in an analytical swaption pricing formula. It explains that this root generally has no closed-form…
The document poses a no-arbitrage relationship for risk-free zero-coupon bonds when interest rates are deterministic. The cost today of investing through two successive periods should equal the cost today of buying a bond that pays at the end of the same…
The document derives the conditional distribution moments for a Vasicek short-rate process with mean-reversion rate, long-run average rate, and constant diffusion coefficient. Rewriting the drift in terms of the long-run level makes the process a…
