FW: Building Yield Curve of Zero Rates

Boafo, Theophilus
 
Hi All,

I have Sample of USD Zero Yield Curve Data as follows:

So I build a vector<QuantLib::Date> yieldMaturities, vector<Rate> yields
from the information above.
In the case of vector<QuantLib::Date> yieldMaturities, I just add the
Maturity Days to observation date.

I now build the yieldCurve as

Handle<YieldTermStructure> yieldCurve(
                                boost::shared_ptr<YieldTermStructure>(
                new ForwardCurve(yieldMaturities,yields,
                                dayCountConv)));

Then pass to

        boost::shared_ptr<BlackProcess> blackProcess(
                            new BlackProcess(underlyingH, yieldCurve,
flatVolTS));

as I am cant determine what the zero rate will be for the exercise date
of the option.

Now given this option is on a commodity forward, I want to discount from
payment date.

Hence have

DiscountFactor expiryDiscount  =
blackProcess->riskFreeRate()->discount(europeanExercise->lastDate());
DiscountFactor paymentDiscount =
blackProcess->riskFreeRate()->discount(paymentDate);

Real forwardValue  = europeanOption.NPV()/expiryDiscount;
Real presentValue  = forwardValue * paymentDiscount;

My PV is slightly off the PV from another system.

The market data is the same in both systems, except for the difference
in discount factors.

The paymentDiscount factor in Quantlib is 0.9990450902703203, whilst
that from the other system is 0.9987391782033116, hence diff in PV.

I am wondering whether my yieldCurve of Zeros has been constructed
properly.

Also its seems YieldTermStructure takes in market quotes and boostraps
zero rates from it. So Given I already have Zero rates, have I
contstructed the Zero Yield Curve propely?  Looks like I have not done
something right.

Hi Theophilus,

Have you constructed the curve correctly? As described in your mail, the
market data is zero yield. However you built the curve as forward curve:

Handle<YieldTermStructure> yieldCurve(
                                boost::shared_ptr<YieldTermStructure>(
                new ForwardCurve(yieldMaturities,yields,
                                dayCountConv)));

That means quantlib took the yields as forward instantaneous rates instead
of zero rates. I think this is where the difference comes from.

Cheng

Re: FW: Building Yield Curve of Zero Rates

Boafo, Theophilus
Hi Cheng,

vector<QuantLib::Date> yieldMaturities;
vector<Rate> yields

So once I populate yieldMaturities and yields, I build zero yield Curve as follow:

 Handle<YieldTermStructure> yieldCurve(
                                boost::shared_ptr<InterpolatedZeroCurve<Linear>>(
                new InterpolatedZeroCurve<Linear>(yieldMaturities,yields,
                                Actual365Fixed())));      

Regards

Theo

I think "InterpolatedZeroCurve" should do the work.

Hi Cheng,

Please do you know the objects used to construct zero yield curves?

Regards
