OIS curve and cross currency basis

<t>If I had eonia rates out to 30yrs and wanted to convert this into USD OIS rates.Do I take the cross currency swap basis and add it to the eonia rates, not sure how to do it with different tenors for swap versus OIS?and then bootstrap to get USD OIS discount factors or boostrap first and then add ...

Volatility skew in local volatility models

<t>Alan just following on from your response, can we link it to vol being proportional to square root of time.So difference between 1y and 4y expiry..vol should be roughly double.Ok sorry this has no impact on flattening of skew..Now that I type this I realize that this is not really the emperical c...

normality vs lognormality rates and equities world

<t>thanks.Zhu have to admit I'm very much on the practical side, so what do you mean by the underlying is not a martingale when the rho is positive? Also what are the applied consequences of that?I know SABRs output is simply the black vol (lognormal) which you stick into BS to give you price. What ...

building a market swap curve

<t>hi all,These days is it safe to assume that every bank on the street using OIS discounting as standard and when they face corporates (e.g. tesco or insurance companies) they simply add a CVA charge to it.I understand that some banks have counterparty specific discount curves where there is not co...

normality vs lognormality rates and equities world

<t>This is beyond basic but -In the rates world, when talking about normality and lognormality are these two unrelated discussions 1. Normalized vol means bp vol and lognormality mean percentage or proportional vol.2. Can we have normalized vol with assuming the underlying rate follows a lognormal d...

practical and basic question on loan and swap and cross currency

<t>Hi..This is a bit of a basic question in a practical setting.If I could take a loan in euros say fixed rate at 6% (say 10 year loan semi-annual payments), how do I calculate the equivalent yield/rate in usd, (I am a company in the us, which cares about things in us dollars).I assume I need to sol...

cross currency swaps with em currencies and spreads

<t>Hello,Two doubts that I have. Just came across a trade. Has anyone ever heard of a bond swap spread being described as the spread between bond yield and cross -currency swap? It doesn't make sense to me.Swap spread is bond yield minus IRS.What are the other driving factors that would affect cross...

Pricing plain vanilla GBP interest rate swaps from many swap rates

<t>QuoteOriginally posted by: MartinghoulYou can't use rates of different underlying terms, because they have different liquidity and risk characteristics. That means that the equations that you would normally use to calculate fwd rates, etc, don't work with inconsistent bases and will produce nonse...

Cost of shorting bond using repo

<t>When traders talk about bonds, is carry just another relative value measure?I assume cost of carry is defined as cost of funding (say GC rate or repo rate) - bond yield (Accrual).So wouldn't that mean almost all bonds now have positive carry?Low rates generate demand for all assets.. In a way the...

re-pricing of lognormality on the top-left

<t>Hi,About 6 months ago before this inflation started to gain some traction, we were pricing in a deflationary path ahead and as a result low strikes on the top-left part of the rate vol surface was going down sharply I assume (normalized vol going down). The more rates rally the more normalized vo...
