The document asks how to adapt cap and floor pricing from the LIBOR framework to compounded overnight reference rates. Under LIBOR, a spot-starting zero-coupon bond can be expressed using a known forward rate, supporting a forward-measure martingale…
The exchange explains the FX basis by comparing two ways to obtain one currency while providing another: borrowing and lending directly, or exchanging currencies at spot and reversing the exchange with a forward trade. A difference in the effective funding…
The document explains how to obtain the short-rate process needed to derive a bond-pricing partial differential equation under the Black–Derman–Toy model. The model specifies the dynamics of the logarithm of the short rate, while the pricing function is…
The document addresses how to interpret a zero rate shown on a Bloomberg curve display when a calculation from nearby quoted rates does not match. One answer recommends working from the displayed discount factors directly and interpolating them to the…
The document distinguishes senior preferred bank bonds from senior unsecured and senior secured debt. It explains that senior preferred status is a category used for bank issuance under European bank recovery and resolution rules, including a German legal…
The document explains a direct way to represent custom amortization when constructing a fixed versus floating interest rate swap in QuantLib. The key idea is to provide each leg with a sequence of notionals aligned with its payment schedule, allowing…
The document raises a question about the Vasicek short-rate model, which assumes mean-reverting rates with normally distributed shocks, and its closed-form zero-coupon bond price. It gives the stochastic differential equation and the affine pricing…
The document asks how credit rating agencies calculate an average annual transition matrix over a multi-year static pool. It contrasts a simple equal-weighted arithmetic mean of separate yearly matrices with other possible averaging approaches, but does not…
The document asks how to construct a euro overnight index swap curve in QuantLib from market quotes. It describes obtaining an overnight rate and swap curve members, sorting instrument quotes by maturity, and creating deposit and overnight swap rate helpers.…
The document lays out a worked approach to calculating Treasury futures gross basis, net basis, and implied repo rate from a cheapest-to-deliver bond. It covers coupon dates, accrued interest, coupon income, financing cost, and the delivery date choice. The…
The document explains why LIBOR was tied to London while appearing in contracts and mortgages elsewhere. London hosted an offshore dollar money market, and the benchmark’s role spread internationally through markets such as interest rate swaps. Some markets…
The document discusses two practical choices in historical scenario analysis for stressed value at risk using a crisis period: what to do when a portfolio asset lacks price history for the selected scenario, and which portfolio exposures to apply. The…
The document addresses how to calculate the future value of recurring deposits made monthly when the deposit amount increases once per year while interest accrues monthly. It presents two approaches for handling the mismatch between payment frequency and…
The document explains why an irregular loan cash-flow stream can produce different annual rates under Excel’s XIRR and the US APR method described in Regulation Z. XIRR solves for an effective annual rate using actual elapsed days and daily compounding on a…
The document outlines a starting point for assessing interest rate risk in a portfolio of Treasury cash securities and futures. It suggests looking for published DV01 information for futures, while noting that broader market data may require a commercial…
The document explains why changing the numeraire and probability measure can make interest rate derivative pricing more tractable. It contrasts the risk neutral measure, where prices are discounted by the money market account, with a forward measure…
The document explains how to construct separate three-month and six-month Euribor forward curves when the indices have a basis. Its central guidance is to use instruments tied to the curve’s own tenor: the relevant Euribor fixing, matching forward rate…
The document contrasts pricing a European put in a collateralized market, where collateral earns the risk-free rate, with an uncollateralized put that creates an unsecured obligation for its writer. The accepted answer says the latter should reflect the…
The document interprets a payment at a future date divided by the sum of zero-coupon bond prices across discrete dates. It defines the resulting amount as a constant coupon whose discounted payments, valued using the corresponding zero-coupon prices, sum to…
The answer describes how to choose the floating-leg spread that makes a swap’s initial value zero when the fixed leg’s value is known. It values each floating coupon using its discount factor and accrual fraction, with the coupon rate equal to the reference…
The document asks how negative interest rates might be modeled for portfolio analysis. It raises possible influences such as credit quality, borrowing and deposit constraints, fixed-asset prices, and cross-currency basis spreads, while questioning whether…
The document considers how to interpolate implied volatility across expiry when bootstrapping a caplet or floorlet surface from cap and floor quotes on a fixed strike grid. It compares a left-continuous rule with linear interpolation. The author observes…
The document considers whether an actively constructed corporate bond portfolio can target a yield premium over a benchmark while still seeking to outperform it. The proposed starting point is to collect historical returns for corporate bonds and form a…
The document distinguishes a forward rate tied to specific calendar dates from a forward rate quoted for a rolling tenor. If the start and end dates remain fixed, the rate observed on a later valuation date reflects changes in the market’s forecast curve;…
