### Who determine Sport rate curve (Yield Curve)

My study was in a Mathematical modelling, we studied much about theory, equations, how to resolve equation, how to implement, but we don't understand well where these equations come from. My ...

### Arbitraging upward sloping yield curve

I read from various sources that yield curve is normally upward sloping. If that's the case, if we borrow short term and lend long term, won't we always make money on average? Let's say 1-year ...

### Is it possible to derive a reasonable USD yield curve using only publicly/freely available data sources?

Background I'm a corporate financial analyst with a small derivatives portfolio (amortizing interest rate swaps and FX forwards) looking to value these derivatives "properly" (which, in my case, ...

### Why QuantLib computes the fixed-leg swap rate by this formula?

I'm trying to understand how QuantLib creates (bootstraps) a yield curve from a vanilla swap at the source level. I have the following test code: ...

### Deriving a 3M libor curve from 6M libor swaps and 3M-6M libor basis swaps

If I had a set of 6M Libor instruments and another set of 3M-6M basis swap instruments, how would I derive the 3M Libor curve? Just bootstrap the 6M curve and the basis curve and add up the zero ...

### Derivation of the Nelson-Siegel model and proof of arbitrage

1. I am looking for a derivation of the Nelson-Siegel model $y(m)=a+b\left( \frac{1-e^{-\lambda m}}{\lambda m}\right)+c\left( \frac{1-e^{-\lambda m}}{\lambda m} -e^{-\lambda m} \right)$ It is ...

### “Friendly” papers about maximum smoothness yield curve modelling

I'm currently looking to implement some version of the yield curve modeling techniques in the maximum smoothness framework. The papers I have found so far explains the theory pretty well, but I find ...

### What is a Basis Swap Curve?

I know what a Swap Curve is. But I don't understand what a Basis Swap Curve is and how it is constructed? Need some guidance on this.
