NZDlibor, LIBOR rate.

New Zealand Dollar LIBOR fixed by BBA.

Fixing calendar : London stock-exchange, payment calendar : London stock-exchange and NewZealand, Business Day Convention MonthEndReference, Currency NZD, DayCounter Actual360 and settlement days of 2 days.



This function creates an object and returns a string-key value to represent this created object.
The TAG value of the string-key returned (second part of the key) is : "NZDLibor"



Note: Within Excel, the function is named - CT.IDX.NZDlibor

Parameter Description


  1. Key parameter

    Key value to use as a handle for the created object
  2. Reload parameter

    When creating this object for the first time, set this parameter to a positive value. Within Excel, when re-computing a worksheet where you do not wish to recreate the object, set this parameter to zero (0).
  3. IndexCode parameter

    Name of new index
  4. Tenor parameter

    Length in Tenor format. (ie - 1W (one week), 2M (two months), 3Y (three years), 4D (four days) ).
  5. LIBORMethod parameter

    Within a Floating leg object, where there are many fixing periods, when fixing a rate there are two ways the end date of a fixing period can be computed. Either 'LIBOR' or 'ParCoupon'. The 'LIBOR' method ignores the end date of the period and computes the end date by adding on the Frequency length (value within the 'Tenor' parameter of this object) to the start date of the period. The 'ParCoupon' method uses the period end date. When this Index is passed to such a floating leg object, this flag informs the floating leg object of which method to use. However for In-Arrear or CMS type legs, the 'LIBOR' method is always used.
  6. BasisSwaps parameter

    An optional 2 or 3 column range of interest rate basis swap tenors and spreads. The third column is an optional boolean column as to whether the basis spread is to be used within the building of this index. The basis spread defined within this index is the basis swap spread between this index and the index (or more rather the deposit template) stored within the yieldCurve object (ie '3M Index' (this index) vs '6M YieldCurve Index' (via the curve's DepositTemplate object) ). This Basis Swap range is required as well as the value within the 'SpreadInterp' parameter if you wish to price basis swaps where there is a spread in order to entice buyers/sellers to trade with this index instead of the default (popular) index stored within the YieldCurve object (via the yieldcurve's Deposit Template
    object, created by the CreateDepoTemplate() function). There are numerous functions for pricing Basis Swaps and portfolio of Basis Swaps ( see BasisSwap() and BasisSwapPortfolio() ). If you do not wish to price basis swaps with this index, simply provide an empty range object (or leave blank in the case of Excel) to the 'BasisSwaps' parameter. Providing a basis swap curve of zeros (0.0), is not the same as providing an empty range because if the definition of this index object and the index within the yieldcurve differs by more than just the Tenor (ie - Business day convention , Calendar, LIBORMethod etc...) then this index will generate a non-zero forward spread curve and thus the FRA rates computed
    via this index will be affected.
  7. SpreadInterp parameter

    Interpolation methodology to utilise when interpolating the forward spread curve (generated from the interest basis swaps). Possible values are : 'BackStep', (for a flat interpolation in the backwards direction), 'ForwardStep', (for a flat interpolation in the forwards direction), 'Linear' or 'LogLinear'.
  8. PastFixings parameter

    Optional past fixings range.
  9. YCKey parameter

    Key to an already constructed YieldCurve object. This curve will be used to extract forward rates based on the details of this Indexes parameters.

Example function usage


The C# example below contains all the sub-function calls leading up to this function call. As a result, the example can contain a lot of code.

The VB.NET, J#, C++.NET, Java, Excel VBA, Visual Basic 6 (via COM) and C++ examples below contain function code stubs for the calls leading up to this function call. However, the function call for this function is displayed.
You can easily reproduce the stub functions code from the C# example.


If you are accessing this functrion via the MiniXL libraries, this function is present within the CT.QL.Curves20 MiniXL Excel Addin.

Within our Excel Example Addin Generator, we have used the following QuantTools sub-functions in order to prepare the arguments needed to call the IDXNZDlibor() function. If you are executing this function via the MiniXL libraries, the module addin name, (in brackets, to the right of the sub-functions listed below), indicates the MiniXL library in which the sub-function is held. You will need to load this library into your Excel session (along with any other libraries that the sub-function call within the addin requires (ie - CT.QT.Utils20 addin in almost all cases) in order for the example to compute successfully.

These are the financial QuantTools sub-function calls that are used within the examples :





The objects generated by these sub-functions are inter-connected in the following way :
