Senaf Basis Terminal



  Market window in Senaf Terminal

 

Reference: Four digits code. In the case of the issues that can be traded with two futures for their residual life a different code will be created for each one of them.

Contracts: It is the number of future contracts equivalent to 1 million € traded in the Basis. The number of contracts of the future trade will be obtained by multiplying this data by the million of € crossed in the cash market issue. The obtained result will be rounded to the nearest integer. (Value date of calculation 8/04/2004).

Basis: We shall show the Spanish issue versus the German future contract.

Volume: Quotation will be done according to the amount gross wished to be obtained in the Spanish issue. When a trade is done the system will calculate according to sensitivity the equivalent number of contracts for the German future.


Gross Basis: Quotation will be done in basis points (three digits for the big figure and 2 decimal places) between the ex-coupon price of the Spanish securities issue and the price of the German future multiplied by the conversion factor of the corresponding Spanish issue.

  Cross of a Basis transaction

The crossing of a basis will generate a trade on the Spanish security and a trade on the German future.

  Future trade price

hen a basis trade is crossed, the last price crossed on the German future in Eurex will be the one applied to the future leg. This price will be obtained through the interface system with Eurex.

  Bond or Obligation trade price

his price will be obtained starting from the price of the future trade, the gross basis to which the basis has been crossed and the conversion factor of the Spanish security.

Issue Spot price = (Future price x Spot Issue conversion factor ) + gross basis

  Conversion Factors Calculating

 


SENAF will provide the conversion factor of the Spanish security relating to the German future contract. This will be the actual value of the Spanish security at the future contract maturity date, of its flows (coupons + amortization) discounted to the theoretical coupon rate of the corresponding future German Notional Bond, less the accrued coupon of the Spanish security at that date, divided by 100.
We shall use the Bank of Spain formula to calculate the actual value of the Spanish security.

  Trade volumes

The trade volume will be that of the Spanish security.

In order to calculate the corresponding number of contracts it will be taken into account the Spanish security sensitivity, the Cheapest to Deliver (CTD) sensitivity of the German issue for each future contract and the CTD conversion factor.

Minimum number of contracts = NOC x SEC x FCC / NCF x SC

NOC: Spanish Security Nominal.
SEC: Spanish Security Sensitivity.
FCC: German CTD Conversion Factor.
NCF: German Future Contract Nominal.
SC: German CTD Sensitivity.

This calculation will be made with the previous day closing data and its result will be a fixed data for the whole session.
The number of future contracts will be obtained multiplying this number by the millions of € crossed in the Spanish security. This result will be rounded to nearest integer.
