Re: libor in arrears

but I don't understand why.   Let the t=0 value of the libor in arrears payment at time one year be lia(0). And let the t=0 value of the libor payment at time one year plus three month be li(0). We know that lia(0) is alway greater than li(0)  ( i.e. lia(0) > li(0 ) Then in order for both contracts ...

For a libor in arrears payment, there is a convexity adjustment for the forward rate.  Is this convexity adjustment always evaluate to positive?

Thanks

Re: libor in arrears

sorry.

for the first contract (i.e. regular FRA), fixed and floating payment takes place at one year plus three months.

for the second contract (i.e. in arrears), fixed and floating payment takes place at one year.

Re: libor in arrears

Why?   Let's consider today's value (t=0) of the floating leg payment in both FRAs.   Because a libor in arrears payment happens at time one year, which is earlier than a regular libor payment at time one year plus three months.  Its value today must be higher than that of the regular libor payment....

Re: libor in arrears

Sorry.  In both cases, the floating rate is the three month libor rate from 1 year to 1 year + 3 months, and it is observed in one year. However, in the first case, payment happens at time 1 year + 3 months.  In the second case, payment happens at time 1 year (i.e. it both sets and pays at time =one...

Basis Risks

Hi,

I have a question on terminology regarding "basis risk".

My understanding is that "basis risk" simply means the difference between two quantities.  But I don't know why in quant finance difference is called basis risk?  Can someone please explain?

Thanks

Re: Bermudan swaptions in hull white model

Hi I am not sure I understand your logic. You are saying that  (1-e^(-a(T-t)))/a is the instantaneous volatility of the zero coupon bond return, increase the mean reversion parameter will make return have less volatility.   But why does making the return of zero coupon bond less volatility have anyt...

Bermudan swaptions in hull white model

Hi, I understand that the mean reversion parameter in the hull-white model (i.e. alpha) controls the level of auto-correlation in the short rate, but how would it affect the valuation of bermudan swaptions? If the auto-correlation increases, does the bermudan swaption price drop because it makes the...
