Data Field (24) Type of index price

No. Field Identifier Description

This field identifies the type of index or reference price used to set the price of the contract. Some contracts, both derivatives and non-derivatives, related to the delivery of gas or electricity are traded on the basis that the price will be fixed by an index value or reference price upon its publication. The price can be classified as fixed “F” when the contract has a fix price (e.g. EUR 50.60), simple index “I” (e.g. a single underlying) or complex price formula (multiple underlying used in a formula). In case none of the above applies, “O” for other shall be used.

Data Field (25) Fixing index

No. Field Identifier Description
25 Fixing index List of indices determining the price in the contract. For each Index specify the name. In case of a basket of indices for which no unique identifier exist the basket or the index shall be indicated.
Description of Accepted Values Type Length Examples
Up to 150 alphanumerical digits. Alphanumeric 150 EUGAS day-ahead Publisher Name

This field identifies the name of the fixing index used to set the price of the transactions executed under the contract. Market participants shall report the name of the fixing index in this field and where the contract has several fixing indexes, each of them should be reported in this field.

As the Agency does not intend to publish a list of indexes because most of them are publicly available and can be readily accessed, the Agency recommends that reporting parties use those indexes exactly as advertised by the publisher.

If the index is not public, then market participants should make best efforts to minimise any discrepancy with the other market participant when reporting this information.

Further guidance on how to report bilaterally agreed index trades in Table 1 and Table 2 is available under Data Field (25) of Table 1 referring to Fixing index or reference price.

Reportable fixing indexes

Only indexes related to the energy commodity should be reported in field 25. This would include also oil and coal or any other energy commodity to fix the price of gas or electricity.

There is no need to report an FX index in the fixing index details section (fields (24) to (30) of Table 2). If for any reasons market participants want to report a FX index, it can be reported in the formula under Data field (15) Price or price formula.

For contract such as option on futures or swaps, as they settle into the underlying future or swap, this should be considered for physical delivery of the underlying contract and the value of “P” should be reported.

A majority of contracts traded under REMIT are for physical delivery, but there may also be derivative contracts that are not reported under EMIR and thus reported under REMIT. Consequently, different types of settlement methods can occur. For further clarification on derivatives not reported under EMIR but reportable under REMIT, please refer to point 3.3.3 of this document.
