### Coupon rate and bond price volatility

The consol volatility actually implied by the market on that day was 16.5%. That value falls within the range, yet that range is too large to convey any information.

### Interest Rate Volatility: A Consol Rate Approach - scirp.org

The following Figure 1 depicts the actual curve together with the model curve.Our choice to focus specifically on the consol volatility is primarily justified by the fact that the consol bonds remains identical to themselves as time elapses, while actual bonds and swaps have a declining time to maturity (as they have a fixed date of maturity).Provides an example of a floating rate bond and discusses how it relates to caps.It turns out that the proxy works well only over the 10 last years of the available sample.This domain is delimited by a parabola, hence the name of the model.Nevertheless, the shape of the zero-coupon curve of OIS for the euro is shown to contain a substantial amount of information about the volatility level, and we have shown how to recover it by con- structing explicitly a proxy of the consol volatility from the curve only,.

Applying Feynman-Kac formula to (10) and then expressing the P as.It turns out that this recognition is easy and we obtain therefore the mathematical shape of our proxy.European Option under Stochastic Interest Rate and. of short rates, the market price of risk of bonds is.

Actual bonds typically promise a fixed interest payment, called the coupon payment, C.The set of all trajectories of r is, the set of continuous functions from.Working with the euro OIS curve, we will present a proxy constructed uniquely from the curve that closely matches the consol volatility.

We will also give a simple expres- sion to the functional of the yield curve that replicates the volatility.Their data sample covered four years and a half and contained weekly observations, so slightly less than 250 observation dates.We will furthermore show, yet only numerically, that it is consistent with a large range consol volatilities.Volatility Risk is the exposure of a bond to the volatility. as rates rise bond prices. and the greater the interest rate risk.As the factor loadings of those 7 factors are known functions of the time to maturity, the regression leads to an expression of.The consol price is a function of the yield curve, which determinates it entirely.The relative size of the option selling position and of the portfolio of swaps is then determined by the vega of the option and by the sensitivity of the portfolio to the proxy.The computation of the proxy from the actual curve leads to a value of 14.8%. While both methods rely on the sole knowledge of the curve, it is clear that the second one obtains better results.

In effect, there exist arbitrage-free models where a given curve shape is consistent with a continuum of volatility levels, and we gIve an example drawn from the category of continuous- time affine models.Valuation of Debt Contracts and their Price Volatility. value of bond depends on coupon (C), interest rate. of interest rate rises, the price of a bond.

Why buy a bond. -- you get 10% on the bond alone, plus another 16% on the coupons,. about bond volatility.The last three months have seen subdued retail sales despite lower oil prices.Bond pricing and interest rates. The first is to price all zero coupon (default free) bonds of varying maturities from a.Let us consider the case of the example seen above in Section 3.2. The observation date was 11 February 2008.Present Value of. volatility in inflation. interest rates in the market are sufficiently less than the coupon rate on the old bond, b) the price.First, for a given term to maturity and initial yield, the price volatility of a bond is greater, the lower the coupon rate.Wei (1997) develops an approximation for coupon bond options prices based on closed-form.

This article has examined the role of the shape of the yield curve in determining interest rate volatility.One result of trading in a bond option, is that the price of the underlying. present value of the coupons between. and short rate (often caplet) volatility,.We introduce a continuous group of transformations T acting on the 9-tuple, indexed by a parameter, as follows.Therefore, the consol volatility summarizes into one unique number a large part of the information contained in the complete market-implied volatility structure.Our primary result is that there exists an empirical regularity (linking rates and volatility) that takes a relatively simple mathematical form.

### Morgan Stanley: Volatility, Limited Upside For Bonds In

The higher the YTM at which a bond trades, the lower the price volatility.We are looking here for an a-theoretical proxy, not grounded on an underlying model and in particular on an arbitrage-free model of the form (15), so the last step is to try and recognize some simple mathematical expression in.It presented a regression of the implied volatility from options on Treasury bond futures on the level of the 1-month, 3-year, and 10-year zero-coupon rates (from the Treasury curve).

In this section, we will show that it is possible to have a curve generated by an arbitrage-free model which could also have been generated by the same model with different parameters, and is consistent with several (different) risk-neutral distributions.It will rise in price faster when interest rates are falling,. (Volatility Index).In Section 3, we will show an example of affine model such that a given curve corresponds to infinitely many specifications of that model.Ideally, it should be able to produce theoretical curves that are consistent with several risk-neutral distributions and several volatility levels.

The error, or difference between the log vol and its proxy, exhibits a strong mean reversion.
