Settlement services – Slovak Republic


Pre-matching service

The table below summarises CBL’s, CBF’s and LuxCSD's pre-matching service for external settlement instructions, as well as the pre-matching method and start time in the market. For details of CBL’s and LuxCSD's pre-matching services, see Pre-matching services for external settlement instructions.

The hold and release feature available in T2S will be used by CBL, CBF and LuxCSD for the pre-matching of settlement instructions in T2S.

(local time)

All securities

CBF and LuxCSD

The T2S hold/release process allows for a released transaction to be set back to hold as long as it has not settled. Instructions that were sent on “Hold” can be released via a corresponding MT540 – MT543 “NEWM”. The status of a CBF/LuxCSD instruction can be changed via a modification (MT530) until its final settlement. In parallel to the instruction hold flag set by the CBF/LuxCSD clients (“Party hold”), T2S provides hold information from the counterparty (“counterparty hold”) itself. Hence, the following values can be reported to CBF/LuxCSD clients:

  • PREA for Party hold;
  • PRCY for Counterparty hold.

Automated through T2S

On receipt of instructions


CBL releases pre-matching instructions (PREA) only outside the provisioning period to CBF for matching purposes only. As soon as the start of the provisioning period is reached and provided the provisioning of cash and securities is successful, the settlement instruction (NEWM) will be released to CBF for further processing and settlement in T2S. Once the instruction is released to CBF, it cannot be set back on hold again.

Matching service

Matching is mandatory for all transactions settling in T2S. In addition to the mandatory matching criteria in T2S the following fields may, if present, be matching criteria.

Additional matching field

The following additional matching fields are initially not mandatory but, when one of the counterparties provides a value for them in its instruction, matching values must be provided by the other counterparty.

  • Opt-out indicator;
  • Cum/Ex indicator.

The Opt-out and Cum/Ex indicators are processed by CDCP for matching purposes as additional matching criteria in T2S, but ignored and not considered for the detection of market and reverse market claims. We recommend not to use these qualifiers for the detection of market claims.

Optional matching field

The following optional matching fields must match when provided by both counterparties:

  • Common reference;
  • Client of delivering/receiving CSD participant;
  • Securities account of the delivering/receiving CSD participant.

Note: Clearstream Banking recommends to agree on the usage of a common reference (:20C::COMM) and the T2S Security Account number (SAC) with the counterparty in CDCP. Both fields are “optional” matching criteria in T2S and avoid cross-matching if it is populated in the Settlement instructions of both parties.

Invalid settlement indicator 

Please note that the settlement indicator CNCB is not valid on the Slovak market. Any instructions containing the settlement indicator CNCB will automatically be rejected.


T2S will send allegement messages depending on the information indicated in the counterparty’s instruction. The allegements will contain the additional and optional matching criteria described above. These can be used to correctly format instructions to ensure matching if it has not yet been sent to Clearstream Banking or LuxCSD.

All securities


If the counterparty of the CBF client instructs first, an allegement instruction will be generated by T2S. T2S will send the allegement message (sese.028) to CBF or to the DCP, without prior validation, whether the ISIN is eligible in the counterparty CSD, that in this case is CBF.

Receipt domestic instructions are automatically generated if the passive matching flag is set on the receiving main account or sub-account. In addition the generation follows the rules below:

For domestic transactions, if the delivering party is an ICP or DCP client and the recipient is a passive matching participant (ICP/DCP), CBF generates the receipt instruction based on the delivery instruction sent to CBF (ICP) or based on the copy of the DCP instruction (sese.023) received from T2S.

For cross-border transactions where the deliverer is a foreign CSD client and the recipient is a CBF client (ICP/DCP), the receipt instruction is generated based on the allegement received from T2S.

Allegements are not generated for “Already matched” instructions.


CBL may receive counterparty instructions alleged on its account at CBF and will report them to clients provided that the client’s CBL account is present in the allegement and the allegement subscription is in place on the client account.


If a counterparty's settlement instruction does not match after the first matching attempt, the client is informed through an allegement message after a predefined period of time (T2S standard service).

Identification of CSDs in T2S

In T2S, all CSDs will be identified by their BIC11. CBL, CBF and LuxCSD clients are required to use the following BIC11 as Place of Settlement for domestic instructions with counterparties in CDCP:



CDCP via T2S


Identification of the counterparty in T2S

In T2S, the CSD participants are identified exclusively by the combination of their home CSD (for example, PSET DAKVDEFFXXX) and their BIC11.

Counterparty identification


4516000 a  counterparty CSD account in CBF) or alternatively CSDSSKBAXXX (BIC11 of the counterparty CSD) b and the T2S Party BIC11 of the CSD participant.

The counterparty CSD BIC is used by CBF to address the CSD where the counterparty is set up as T2S Party. This counterparty's CSD is reflected in CASCADE with a counterparty CSD account. The counterparty CSD BIC has to be used in cross-border instructions with T2S In-CSDs.


Home CSD BIC11 and the T2S Party BIC11 of the CSD participant.

If a CBL client uses a BIC8 to identify the Receiving/Delivering Agent, CBL shall be entitled to modify the BIC8 provided and the settlement instructions will be then processed by default with a BIC11 by adding the default XXX suffix to comply with T2S settlement rules. Accordingly, such clients remain liable for any settlement fails that the use of the BIC8 may cause and the clients furthermore agree to indemnify CBL against losses, liabilities, damages, penalties, expenses and all other costs on any kind suffered by CBL as a result of the client not complying with the above requirement.

b. BIC11 of other T2S IN-CSDs possible if the technical configuration in T2S is available.

Note: Cross-border settlement between CSDs in T2S is only possible, if the corresponding technical configuration in T2S for cross-border links has been established by the CSDs linked to each other.

a. Although the safekeeping account of Party 1 (REAG/DEAG) is an optional matching field in T2S, if it is present on one instruction only it will only match with instructions instructed by this account.

As CBL does not forward its own SAC to the settlement parties, if the client counterparty instructs the SAFE of REAG/DEAG it must match CBL's SAC in T2S exactly.

We encourage clients to ask their counterparties not to include the SAFE of the DEAG/REAG in their instructions (also called securities account of the delivering/receiving party).

Partial settlement

In T2S, partial settlement for eligible instructions is allowed at the last night-time settlement cycle in sequence ‘X’; and within the real-time settlement period:

  • At 08:00 CET, 10:00 CET, 12:00 CET, 14:00 CET and 15:30 CET.
  • 30 minutes prior to the against payment cut-off time (between 15:30 CET and 16:00 CET).

Within these windows all transactions that are pending due to lack of securities and hold a positive partial settlement indicator are included in the partial settlement processing.

Whether partial settlement will be applied or not depends on the partial settlement indicator set within the instruction or on the client account setup. A settlement instruction will settle partially if both counterparties instruct with the Field :22F::PARQ.

Partial settlement applies only when full settlement is not possible due to lack of securities. T2S will perform partial settlement according to the available position after analysing the partial settlement indicator in the instruction. The settlement instructions are submitted to a full settlement attempt before being submitted to a partial settlement attempt, if permitted by instruction indicators or client account setup.

Partial settlement is applicable to domestic and cross-border instructions and is not allowed for PFoD instructions. Also, partial settlement is not applied if instructions are linked to any other settlement instruction with link type “Before”, “After”, “With” or via pool reference. Partial settlement is not applied if the transaction undergoes a process where a CoSD Hold is used. The unsettled remaining part of a partially settled settlement instruction can be cancelled.


CBF clients can define within the instruction whether partial settlement is to be applied or not by setting a partial settlement indicator. In addition, they can set a flag on account level (CBF 7-digit account number) that defines the default value to be set to those instructions where the partial settlement indicator is not filled. The flag is maintained within CBF’s static account database and defines which partial settlement indicator is to be assigned to an instruction as default value (NPAR, PART).The flag applies to delivery and receipt instructions.


As client delivery instructions are always fully provisioned before being sent to the domestic market, no partial settlement can be performed. For receipts, the partial settlement can take place if the counterparty is short of securities and the instructions are received by T2S within the times set above.

When CBL clients access T2S via CBF, the default set up will be Partial Settlement. Clients that do not wish their transactions to settle partially must provide the No Partial Settlement indicator (NPAR) in their instruction.


LuxCSD clients can define within the instruction whether partial settlement is to be applied or not by setting a partial settlement indicator.

Allowed countervalue difference

The following T2S cash tolerances will apply to instructions (against payment instructions in EUR only):

  • EUR 2 for transactions with an amount equal to or less than EUR 100,000; and
  • EUR 25 for transactions with an amount greater than EUR 100,000.

In the event of a discrepancy within the limits, in principle the cash amount of the delivering party will prevail.

For non-EUR currencies, the T2S cash tolerances apply to against payment instructions in foreign currencies between CBL and CBF participants (not applicable to LuxCSD).

Bridge settlement (CBL only)

CBL clients can settle CDCP T2S-eligible securities via the Bridge. This service is not available for CBF and LuxCSD clients.

Back-to-back processing (Transaction Linking)

Back-to-back processing is available for transactions in CDCP T2S-eligible securities.


Unmatched instructions can be cancelled unilaterally, at any time, by the party who placed the instruction or until cancelled by T2S.

Matched instructions must be cancelled bilaterally by both counterparties.

Recycling rules

Unmatched instructions will be recycled for 20 business days (starting from the initial settlement date), after which they will be cancelled.

Unmatched cancellation requests will be recycled for 20 business days (starting from the date of receipt).

Matched, but not settled instructions will be cancelled by T2S after 60 business days (starting from the date of receipt or on the day the last modification was sent for the instruction).

Settlement Discipline Regime cash penalties

Penalties will be calculated and applied on matched settlement instructions that fail to settle, in full or in part, on and after their intended settlement date (ISD), if both the settlement instruction and the relevant financial instrument are subject to cash penalties.

Instruments subject to cash penalties

Any financial instrument listed in the Financial Instruments Reference Data System (FIRDS) database maintained by ESMA will be subject to cash penalties. However, cash penalties will not apply to shares listed in the Short Selling Regulation (SSR) exemption listed in the Short Selling Regulation (SSR) exemption list.

New issues settlement

Government securities

The settlement cycle for primary auctions of Slovak government bonds is T+2.

Auctions on Slovak government securities are organised by the Debt and Liquidity Management Agency (ARDAL) in the name of the Ministry of Finance.

Since the implementation of T2S, new rules are applicable and settlement of the primary auctions is done only via an against payment instruction in T2S, for each order. It is no longer possible to settle via free of payment instructions coupled with a separate cash payment.

Cash and securities settlement must be processed in line with the auction conditions on the settlement day. Unless otherwise agreed, the settlement date is the second business day following the auction day.

The input deadline is as shown for against payment settlement on Settlement times – Slovak Republic).

Counterparty BIC of ARDAL is APRDSKB1XXX.

  • Clients who want to participate in a primary auction should contact a primary dealer or their broker-dealer to place their bid.
  • Clients that are already primary dealers should send to Clearstream a receipt against payment instruction for each successful bid.
