How would you hedge this? abs(fix(t)-fix(t-1))

How would you hedge this? abs(fix(t)-fix(t-1))

Hi,a sales ran to me asking to price a bond paying this: abs(fix(t)-fix(t-1))i.e. every year the bond pays a coupon equal to the fixing of the Euribor (in arrears, i.e. the spot fixing) and the fixing of the euribor one year earlier. It that a kind of vol bond?THanks,Cactus

Interest rate option (swaptions & caps/floors)

<t>Hi,this is an old post, but I'll try to write some more. As far I can see, as someone has stated BP VoL=strike*Yield Vol (quoted on the broker page,i.e. ATM strike).If you want to calculate the BP Vol for an OTM strike, what you can do is one of the following: 1. otmBPVOL= strike*otmYield Vol2. o...

Market Vol, Vol trading and Non Farm Payrolls...

So, if a volatility frown exist in the Fixed income market, being long vega= long the market, while being short vega=short the market. That's why yield vols rise when market goes up , while yield vols fall when the market goes down, that keeping basis point vols constant. Is that correct?
