Bank of Zambia ZIPSS Rules

General Principles and Objectives
The purpose of this document is to define the System Rules for the Zambia Interbank Payment and Settlement System (ZIPSS) which is the interbank payment system or the Real Time Gross Settlement (RTGS) system for Zambia. These Rules are issued in accordance with the National Payments System Act Number 1 of 2007 and define various operating aspects of ZIPSS, together with the duties and obligations of all Participants including the Bank of Zambia in its role of System Operator as well as Participant.
1.1 General
ZIPSS (hereinafter “the System”) is the interbank payment and settlement or the Real Time Gross Settlement (RTGS) system for the Bank of Zambia (BoZ). ZIPSS ensures:
 The final and irrevocable gross settlement in Participants’ Settlement Accounts (SAs) of RTGS Payments initiated by Participants;  The final and irrevocable settlement in Participants’ SAs of the net positions arising from the deferred net settlement (DNS) operations from existing clearing houses and any other clearing systems that may be approved from time to time by BoZ;  The settlement of the payment part of the securities transactions from the securities clearing and settlement system;  The final and irrevocable settlement of transactions involving Government securities processed through the securities registration system maintained by BoZ. These Rules shall be applicable to all Participants authorised by BoZ. The Participants of ZIPSS shall act in their own name. In order to become a Participant, an institution shall comply with the criteria on operational capacity, financial soundness, legal soundness and financial requirements as detailed below in section 2 – Access Criteria and Conditions. The “Rules” shall mean these Rules and each related Annex and attachment thereto and hereto, as supplemented by related materials, including User Manuals, system documentation and other documentation provided (the Materials). Any of these Materials may be amended from time to time. Where there is a conflict between these Rules and any Annex, the terms of the Annex shall prevail in respect of the relevant Service. Section 24 describes how these Rules may be amended from time to time.

Bank of Zambia ZIPSS Rules
All time indications in these rules relate to the time at the place where the head office of BoZ is located. The specific terminology of ZIPSS and the symbols used are explained in the Glossary.
1.2 Roles of Bank of Zambia
BoZ shall be the System and Technical Operator of ZIPSS with the legal responsibility for controlling, managing and operating ZIPSS. In its capacity as the Central Bank of Zambia, BoZ administers the Settlement Accounts (SAs) of the Participants, provides intraday liquidity and other facilities to ensure efficient and sound payment systems. In this respect, BoZ oversees the payment systems activities in Zambia, and acts as a settlement agent in its capacity as System Operator of ZIPSS. In its capacity as System Operator, BoZ shall be responsible for:

Authorisation of Participants in ZIPSS;
The establishment and maintenance of these Rules and related Procedures; and
The authorisation of operating standards and procedures of ZIPSS.
BoZ shall oversee the adherence to these Rules by the Participants. As Technical Operator of ZIPSS, BoZ shall administer the operation of the daily business cycle, manage the creation of reports and charts and shall be responsible for the security of ZIPSS data, software and infrastructure, including managing backups and fall-back situations. BoZ may, at its own discretion, delegate operational tasks to third parties. This delegation will not in any way affect BoZ’s responsibilities towards the Participants.

Bank of Zambia ZIPSS Rules
2. Access Criteria and Conditions
2.1 Categories of Participants
The following entities shall participate in ZIPSS:
 Commercial Banks licensed by BoZ;
 Clearing Houses authorised by BoZ;
 BoZ; and
 Any Other entity authorised by the Bank.
2.2 Operational Capacity
2.2.1 Equipment
Participants shall procure their own equipment. BoZ shall not be obliged to supply to Participants any hardware or operating system software to enable utilisation of the Services on ZIPSS. BoZ shall provide to each Participant any necessary components such as a limited number of initial set of e-tokens as determined from time to time. Participants will install and configure the components to support the ZIPSS software in accordance with BoZ’s instructions. The Participant shall at no time have any proprietary interest in the ZIPSS software. Any supporting components provided by BoZ shall be returned to BoZ on termination in accordance with section 2.2.2 of these Rules or earlier on demand.
2.2.2 Materials
The Materials provided in connection with the Services (including, for example, access to ZIPSS) are the exclusive and confidential property of BoZ. The Participants agree to keep these Materials confidential, to limit access to their employees (under a similar duty of confidentiality) who require access for the proper use of the Services, and to use all Materials in the manner designated therein and in the ordinary course of their business, and not to modify any. The Rules shall not affect the copyright status of any of the Materials and the provisions of this paragraph will apply whether or not such Materials are copyright protected.

Bank of Zambia ZIPSS Rules
2.2.3 Primary and Fall-back Computer Facilities
Each Participant shall provide fall-back IT equipment for treasury management, accounting and access to the ZIPSS. Both primary and fall-back IT equipment shall be operated by qualified and authorised personnel who will take appropriate action on behalf of the Participant with respect to the operations of such computer facilities in accordance with these Rules. Documents describing the standards and communication protocols (and other functional requirements) for a Participant’s computer interface to ZIPSS shall be provided by BoZ to each Participant that connects to ZIPSS, as itemised in Annex 13. Each Participant shall comply with, and its computer interface must function in accordance with, such standards and protocols. A computer interface shall not be implemented unless it has been approved by BoZ. In order to ensure the stable and correct functioning of the System, BoZ may make the participation of a Participant in ZIPSS, as well as the maintenance of such participation, dependent upon the successful outcome of tests demonstrating that the Participant has the operational and technical capacity required (notably with regard to its IT systems and telecommunications). BoZ shall communicate the contents, conditions and dates of these tests to each Participant concerned. BoZ shall not be responsible for any expense incurred by a Participant in establishing any primary or fall-back facility connected to ZIPSS. Each Participant shall have a Business Identifier Code (BIC) as issued by the Society for Worldwide Interbank Financial Telecommunications (SWIFT). Where appropriate, BoZ may assign an unlisted BIC to a Participant that does not connect to the ZIPSS through the SWIFT network. The BICs of the Participants are specified in Annex 2. Each Participant shall be connected via a Webstation as specified in Annex 14, configured to exchange messages with the ZIPSS and communicating via the ZIPSS virtual private network (VPN). Participants shall use the SWIFT network to enable Straight-Through Processing (STP) of transactions between their payment-originating systems and ZIPSS.

Bank of Zambia ZIPSS Rules
2.2.4 Staffing at Connection and Changes to Connection
The office(s) of the Participant’s primary connection shall be staffed by personnel who are qualified and authorised at all times by the Participant to take appropriate action on behalf of the Participant with respect to the connection after having signed the E-Token Application Form in Annex 4.
2.2.5 Location of Computer Facilities
Any primary or fall-back connection linked to ZIPSS shall be located only in a location deemed suitable by BOZ. Any Participant wishing to change the location of its primary connection shall obtain the approval, in writing from BOZ (Note in the Glossary the definition of “In writing”). Any changes to the location of a primary or fall-back connection shall not be a valid reason for requesting any changes to the ZIPSS operating timetable. Any Participant wishing to change the location or the operational characteristics of its primary or fall-back facility must present a proposed plan describing the change and obtain approval from BOZ in advance of making the change. BOZ reserves the right to require the Participant to alter the plan if in the opinion of BoZ, the plan poses a risk to the operational integrity of ZIPSS.
2.2.6 Authorized Settlement Agent (ASA) facility
All Participants shall be expected to provide adequate contingency in terms of infrastructure (software, hardware and communications) for the purpose of making payments on ZIPSS. However, in some contingent situations where a Participant is unable to generate transactions on the core banking system, the Participant may be allowed to request the BoZ to process transactions on its behalf using the Authorized Settlement Agent (ASA) facility. Prior to using the facility, the Participant shall inform BoZ through the office of the ‘Assistant Director Development & Operations – Payment Systems Department’ In writing detailing the problem being experienced. The Participant shall then fill in the ASA Form, with details of the transactions to be processed. Where a Participant need to process several transactions, the Participant is expected to fill in a separate ASA Form for each transaction being processed. BoZ shall only act on original authenticated payment instructions.

Bank of Zambia ZIPSS Rules
In exceptional circumstances, the Bank shall accept scanned copies of ASA instructions sent by an authorised signatory to zipss@boz.zm. A charge will be applied for each transaction that is processed on behalf of the Participant and the total amount charged will be debited from the Settlement account of the Participant (refer to Annex 8 – Pricing). In processing such transactions, the following conditions will be considered; a) BoZ will only process critical and systemically important transactions such as interbank, cash, government securities, payments to BoZ and ZRA transactions; b) BoZ reserves the right to introduce an incremental charge for using the ASA facility consecutively; and c) The deadline for submitting requests for processing ASA transactions from a Participant shall be at 15:00 hours. A Participant shall ensure that ASA instructions are received by BoZ before the stipulated time.
2.2.7 Participant Workstation Minimum Configuration Requirements
Participants’ ZIPSS web stations must comply at all times with the minimum configuration requirements as detailed in Annex 14.

Bank of Zambia ZIPSS Rules
BoZ shall at its discretion decide on any term or grace period, taking into account the specific situation of the Participant concerned. A Participant whose access to ZIPSS is suspended under this section is not entitled to participate in ZIPSS, but it still has a right to access its data outside the system via a request to BoZ. A Participant whose access to ZIPSS is suspended is not excused from discharging its obligations under these Rules, except as expressly provided in or pursuant to these Rules. From the moment BoZ decides that the suspension becomes effective, any Payment Instruction from the respective Participant is no longer accepted until the reinstatement date. BoZ shall immediately notify all Participants (by the most expeditious means available) of any suspension. BoZ may at its discretion reinstate a suspended Participant and shall as soon as reasonably possible, notify all Participants of any decision to reinstate a suspended Participant including the re-commencement (“activation”) date for that Participant.

The notice shall be irrevocable. However, all licensed banks within BoZ’s definition, shall maintain their membership in ZIPSS.

Bank of Zambia ZIPSS Rules
BoZ may terminate, in writing, a Participant’s access to ZIPSS with immediate effect where all of the following conditions have occurred, unless agreed otherwise or no other formalities or court intervention is required:
a) a Suspension event has occurred in respect of that Participant and has not been remedied within a reasonable period; b) that Participant is subject to prudential supervisory actions; and c) BoZ has provided an opportunity for a Participant to make submissions regarding such termination. BoZ shall not be obliged to give any reasons for such decision and may revoke any such notice at any time before it becomes effective. Any termination of access to ZIPSS shall not affect any right or liability arising under these Rules prior to the time such termination takes effect or arising in respect of any act, matter or thing occurring prior to that time. A Participant whose access is terminated pursuant to this section shall continue to be bound by these Rules in respect of:
a) any act, matter or thing occurring prior to the time such termination takes effect or as a result of such termination; and b) any fees, costs, charges and expenses which may be levied on, or which are to be reimbursed by Participants in accordance with these Rules in respect of periods which commence prior to the time such termination takes effect or which relate to any such act, matter or thing. BoZ shall immediately notify all Participants (by the most expeditious means available) of any termination under this section. Subject to any rights of set-off, counterclaim or combination, which are available at law, upon any termination of the access of a Participant:
a) the terminating Participant shall immediately pay all sums of money (if any) owed by it to any other Participant in respect of obligations arising from the exchange of payments; and b) all sums of money (if any) owed to it by any other Participant in respect of all such payments exchanged shall be paid by that other Participant to the terminating Participant.

Bank of Zambia ZIPSS Rules
4.1.3 Cyber Security Risk Management Frameworks and Measures
A Participant shall at a minimum:
 Cyber-Risk Management Framework
Put in place a cyber-risk management framework to mitigate against cyberattacks on the ZIPSS. The cyber-risk management framework shall prescribe measures to be taken by a Participant to fully recover its operations where a cyber-breach affects its operations.  Restricted Physical Access Physical access to ZIPSS workstations including at the fall back sites shall be restricted and strictly controlled from being accessed by unauthorized persons.  Segregation of duties Participants shall ensure segregation of duties by creating profiles that separate business functions and duties.  Token Management Each User shall ensure that their e-token is kept safely at all times. The e-token default password should be changed when the User logs in for the first time and the new password should not be shared.  Password Management Users shall create strong and unique passwords whose complexity shall have a minimum of eight characters, a combination of upper and lowercase letters and either a number or symbol/special character. Users should ensure that the passwords are changed regularly and that they are never shared with another person.  Monitoring tools Implement monitoring tools/capabilities that are able to identify and prevent system breach.  Detection of breach Where a breach is detected, the tools/capabilities must quickly identify the breach and quarantine the threat to minimise impact, loss or damage.  Prevent Reoccurrence

Bank of Zambia ZIPSS Rules
Ensure that measures are put in place to prevent reoccurrence of an attempted or successful breach.  Cyber-Risk Assessment Undertake regular cyber-risk assessment, and review effectiveness of internal cyber risk controls.  Cyber security awareness Participants shall undertake cyber-risk awareness among its staff and users of the ZIPSS and any other relevant stakeholders.  Cyber Security Incident Response Guide Each participant shall have in place an incident response plan to deal with material cyber security breaches or attempts. A recovery and assurance plan shall ensure system’s integrity following the cyber security incident as well as recovery of lost or corrupted data due to the cyber security incident.  Cyber Communication and Information sharing strategy Each participant shall report major breaches to the BoZ within 24 hours of discovering the breach. The incidents shall be reported through email at zipss@boz.zm.  Appointment of Participant Security Administrators Each Participant shall designate among its staff a minimum of two Participant Security Administrators who shall be responsible for communication with BoZ and executing tasks regarding:
a) The set-up of Users; b) Amendment of User profiles; c) Removal of Users from the system, and d) The management of e-token and certificate issue and delivery to endUsers. BoZ shall maintain the list of Participant Security Administrators.
4.2 Communications
Each Participant and BoZ agrees that the Services shall be provided using the communication methods described in these Rules. Electronic communication is subject to the communication and data security methods as set forth in these Rules. The Participants agree to comply with the applicable procedures and the methods designated in these Rules.

Bank of Zambia ZIPSS Rules
BoZ is not obliged to follow instructions unless transmitted in accordance with these Rules. Nonetheless, the Participants hereby agree that if BoZ acts upon a request from an Authorised Person to accept an instruction given without following an agreed Procedure (a “special instruction”) for whatever reason, the Participant will be bound by such special instruction and will indemnify and hold BoZ harmless from any loss, liability, claim or expense (including legal fees) attributable to executing such special instruction. If BoZ takes any action beyond those agreed in these Rules to verify the source or content of any communication, such additional action shall not be deemed to become part of the Procedures no matter how often BoZ takes such additional action.
4.3 Use of BOZ-Supplied Materials
The security procedures, security devices, codes, passwords and other access methods are highly confidential and the Participants shall use and guard them with the highest care and notify BoZ immediately upon discovering or having reason to suspect that any of the foregoing is or may be compromised. Where software and/or hardware provided by BoZ to a Participant incorporates features relating to security (including IDs, e-tokens and passwords and other measures) the Participant shall be solely responsible for the use of such features. BoZ shall be entitled to assume that all use of such software and/or hardware is by persons authorised to access such facilities.
4.4 Password Policy Management

5. Establishment and Maintenance of Users
5.1 General
Access to ZIPSS shall only be permitted to authorised and uniquely identified personnel (Users). Each person named in the corresponding E-Token Application form (as specified in
Annex 4) shall be an Authorised Person or the designee thereof duly authorised to
receive, transmit and/or confirm data and instructions within the limits, if any, specified on the applicable E-Token Application form (a User). As long as BoZ acts in compliance with the communication and data security methods as set forth in these Rules, which may be amended from time to time in accordance with the Procedures in these Rules, it shall have no further duty to verify the identity or authority of the person giving or confirming, or the contents of, any instruction. Notwithstanding any other provision hereof, BoZ shall have the right, in its sole discretion, to refuse to execute any instruction, provided BoZ, acting in good faith, doubts the authenticity or authorisation thereof. BoZ shall provide prompt notice, which may be by telephone, to an Authorised Person of any such rejected instruction. BoZ shall be entitled to rely on the authorisations and User lists as set forth on a EToken Application form until receipt by BoZ, in normal circumstances at least two Business Days prior to the effective date thereof, of a written request for revocation or modification of such application form, dated and signed by an Authorised Person. In urgent cases such request for revocation or modification may be made by Secure Email and will be actioned by BoZ immediately on receipt. An E-Token Application form may be revised only by a written request signed by an Authorised Person and each such proposed revision is subject to BoZ’s consent in accordance with the procedure laid down in sections 5.3, 5.4, and 5.5 of these Rules. This section supersedes all prior agreements or practices in respect of instructions and the Procedures and may not be changed by an oral agreement or by course of dealing or custom. Each Participant will inform BoZ immediately if any person authorised to utilise the Services on behalf of a Participant ceases to be employed by that Participant or ceases otherwise to work for that Participant or to be under its control.

Bank of Zambia ZIPSS Rules
5.2 Request to Create a User
Each Participant requesting the authorisation of a User shall, at least two Business Days prior to the effective date thereof, complete and provide to BoZ In writing an E-Token Application form, as provided in Annex 4, dated and signed by an Authorised Person. BoZ shall reserve the right to:
a) allocate e-tokens; and b) issue a digital certificate to the User (on the e-token). Participants through their Security Administrators are responsible for the creation and maintenance of their other Users in the ZIPSS system, allocation of Usernames, User profiles and initial passwords. Before a User can be registered, Participants shall ensure that the User has been trained appropriately to perform the functions on ZIPSS. BoZ shall provide one e-token with a password to each registered User. Each e-token shall be exclusive to the user to whom it is issued, and in no circumstances shall it to be shared with or used by another. When received by the registered User, the token’s default password should immediately be changed. After the initial allocation, BoZ reserves the right to charge the cost of tokens to the Participants, e.g. for replacement tokens and expansion of the User base.
5.3 Request to Modify a User
Only Participant Security Administrators can assign and amend User profiles according to User responsibilities, required by Participants or by BoZ. Such assignments and amendments will take place under dual control.
5.4 Request to Suspend or Delete a User
A Participant that requires one or more of its Users to be suspended or deleted can carry out the deletion on-line, but must report to BoZ in writing that a User has been suspended or deleted. The report should be submitted on the E-Token Revocation form (see Annex 5). BoZ reserves the right to suspend or delete a User from ZIPSS.

Bank of Zambia ZIPSS Rules
5.5 Creation and Maintenance of User Profiles
BoZ Administrators shall allocate initial User profiles to Participants User Security Administrators and may, in the name and for the account of BoZ amend information about a User, including the User profile, according to the information provided by Participant administrators. BoZ shall approve specific master templates for each Participant. Within the restrictions of this template, Participant User Security Administrators shall define profiles for their staff, consistent with the segregation of duties principles. BoZ shall set up the master template on ZIPSS.

Bank of Zambia ZIPSS Rules
6. Financial Collateral Arrangements
6.1 Establishment of Reserves Accounts
Each ZIPSS Participant may have a number of Reserve Accounts linked to its Settlement Account (SA). Establishment of a Reserve account shall allow participants to move funds in the System from the Settlement account to a Reserve account where they can only be used by ZIPSS for designated purposes. Participants can move funds into and out of Reserve Accounts as they wish unless otherwise restricted by the BoZ. In addition to the Participants SA and Statutory Reserve Account, each Participant shall have:
(i) Cash Reserve account into which it shall move funds for settling cash withdrawals; and (ii) NSI Reserve account for settling obligations arising from clearing operations. ZIPSS will lock the NSI Reserve account during each clearing session.
6.2 Provision of intraday loan facility (ILF)
BoZ shall provide interest free intra-day credit to Participants during the period prescribed in Annex 7. Participants shall be able to pledge government securities on ZIPSS, using the CSD system, for use as collateral for intraday loan facility. Participants may use intraday credit to the tune of the value of securities pledged by the Participant taking into account the haircuts as shall be determined by BoZ. BoZ reserves the right to introduce a cap to the amount of intraday credit that may be accessed on ZIPSS by a participant. Such a cap, when introduced, shall be communicated in writing to all Participants. Where a Participant persistently utilizes intra-day credit, BoZ shall take supervisory action against the Participant, which may include suspending the provision of intra-day liquidity to the that Participant.

7. Settlement of Net Settlement Instructions (NSIs)
NSIs generated externally from clearing operations shall settle in Participants’ SAs in ZIPSS. NSIs shall settle as “all-or-nothing” multi-part transactions, with all debits and credits settling simultaneously as a batch. It shall be the responsibility of each Participant to ensure that they have sufficient funds in their Settlement Account and/or NSI Reserve account to cover their net position in each settlement session. In the event that a Participant does not provide funds in the NSI Reserve Account prior to settlement, ZIPSS shall automatically transfer funds from the Participant’s SA to the Participant’s NSI Reserve Account to cover the gross debit position. As soon as an NSI is entered into ZIPSS for settlement, funds to the tune of the debit amount shall automatically be blocked in the SAs of Participants that have a net debit position in the NSI, to enable the immediate Settlement of the NSI. If funds are not available in the SA or the NSI Reserve account of a Participant with a debit position, the NSI shall be queued until sufficient funds become available. A Participant that causes the NSI not to settle at the designated time shall be charged a penalty. BZ reserves the Right to transfer Funds from the Participant’s Statutory Account to the SA to facilitate settlement of an NSI and the Participant shall be expected to comply with the Statutory Requirements as shall be determined by BoZ from time to time. If at Initial Cut Off, an NSI is still pending due to insufficient funds, the Participant shall be required to issue instruction to the Bank of Zambia to rediscount securities pledged under the ZECHL collateral.

10. Processing Procedure
10.1 General Issuing Conditions
Participants shall comply with the timetable in Annex 7 and shall undertake to present the different types of Payment Instructions before the cut-off times stated in this timetable. Participants wishing to apply for an extension of the cut-offs on ZIPSS shall be required to fill out the form in Annex 18. The completed application shall be signed by two (2) authorised signatories and shall be sent to zipss@boz.zm no later than 15:30 hours. The conditions under which the Bank shall consider to extend the system include the following:
i. System wide challenges on the ZIPSS;
ii. System wide challenges on ZECHL operated payment platforms (EFT, CIC
and NFS);
iii. Processing of systemically important/critical payments;
iv. Challenges impacting the ZIPSS on account of integration with other critical
infrastructures;
v. To facilitate system maintenance;
vi. Challenges with the ZIPSS infrastructures. Where all or a significant number
of Participants fail to access the system via the SWIFT network or VPN. BoZ shall determine the duration of the extension and reserves the right to reject an application for extension. An approved application for extension shall attract a fee as prescribed by the Bank. Participants shall monitor the messages in the outward ZIPSS Pending Queue and take the necessary action to clear any pending transactions before the Final Cut-Off. Transactions that do not settle at final cut-off shall be cancelled and shall attract a charge as detailed in Annex 8 – Pricing.
10.2 Submission and Validation
The Participants shall take all necessary measures to optimise the smooth flow of the payments, especially by adhering strictly to the timetable in Annex 7.

Bank of Zambia ZIPSS Rules
Payment Instructions sent by Participants shall immediately be validated by ZIPSS. If a Payment Instruction is rejected, an error message shall be sent to the issuer. A list of error codes is set out in Annex 15. The ‘handover point’ between a Participant and ZIPSS is the point of Technical Acceptance. This is when ZIPSS has received and validated a message as being a valid message and has therefore accepted it for settlement. An acknowledgement message is sent to the sending bank at this point. The accepted messages are recorded and chronologically processed by the system according to the FIFO (“First In First Out”) principle within the specified Priority.
10.3 Queuing
ZIPSS payments shall be settled as follows:
a) the information necessary for settling the payment shall be extracted from the detailed Payment Instruction; b) if the sender has sufficient funds available, the payment shall be settled (paying Participant debited, beneficial Participant credited) and immediately becomes final; c) if the funds are insufficient to settle the payment, ZIPSS shall put the Payment Instruction in the Pending Queue until the funds become available. d) if the funds remain insufficient at system cut-off times, the pending transaction shall be cancelled in accordance with the operating timetable.
10.4 Processing of Payment Instructions in the Pending Queue
A Participant who wishes to have a ZIPSS Payment message to be treated preferentially, shall assign a higher priority code in such a message. The order in which payments in the Pending Queues are executed depends first on the priority and second on the time they are validated by ZIPSS. All payments with the same priority shall be processed on the basis of the FIFO (“First In First Out”) principle.

Bank of Zambia ZIPSS Rules
10.5 Cancellation of Queued Payment Instructions
10.5.1 By the Issuer
Payment instructions queued by ZIPSS may be cancelled by the sending Participant in exceptional circumstances.
10.5.2 By BOZ
BoZ can cancel any queued Payment Instructions in order to facilitate the smooth flow of funds through the system. In such case BoZ shall immediately inform the initiating Participant. ZIPSS shall automatically cancel any queued ZIPSS payments for current business day value that have not been settled at Final-cut-off.
10.6 Processing of NSI
NSIs shall be submitted automatically to the ZIPSS settlement engine at the specified time for settlement. A Participant shall ensure that sufficient liquidity is available to settle the NSI generated at the end of each Clearing session. If the NSI is not settled it shall be queued in the normal way.
10.7 Gridlock Resolution
10.7.1 Initiation of Gridlock Resolution
If the value of the ZIPSS Payment Instructions in the Pending Queue leads to saturation of the system, or if two or more Participant’s queues become blocked with Payment Instructions, Gridlock Resolution within ZIPSS shall be initiated automatically. Gridlock Resolution shall be achieved by simulating a bilateral or multilateral netting procedure. Participants shall be expected to monitor their SAs during the day and ensure that they have sufficient funds available to meet their settlement responsibilities. BoZ will monitor the position of each Participant and may advise Participants to take the necessary steps to unblock the situation.
10.7.2 Delayed Gridlock Resolution
Initiation of Gridlock Resolution shall automatically be delayed by the entry of an NSI until such time as ZIPSS has attempted to settle the NSI transaction. If Gridlock

Bank of Zambia ZIPSS Rules
Resolution is already running when an NSI transaction is entered, it will be completed before the NSI is processed.

Bank of Zambia ZIPSS Rules
11. Irrevocability of Payment Instructions
11.1 Moment of Entry into the System
The moment of entry into the system is the moment of the Technical Acceptance of a payment instruction by ZIPSS, i.e. after validation but before acceptance for Settlement (before passing the Available Funds test) or queuing of the Payment Instruction by ZIPSS. As from that moment, the Settlement of the Payment Instruction will be protected against claw-back in case of insolvency of the Participant concerned, in accordance with the National Payments System Act Number 1 of 2007.
11.2 Irrevocability and Finality of Payment Instructions
Settlement will be final and irrevocable once settlement accounts of respective participants have been credited and debited with the amount specified in the payment instructions.

Bank of Zambia ZIPSS Rules
12. Reports and Enquiry Facilities
ZIPSS shall provide the Participant with systematic information on:
a) its Intraday Credit position at BoZ; b) the state of its SA; c) the transactions on its SA; and d) its Pending Queue with ZIPSS Payments and NSIs still to be processed.

19.1 Audit Trails
ZIPSS generates comprehensive audit trails which participants can access on request. For Participants, access to audit trail data will be restricted by use of User profiles. Where an auditor or any other legal entity wishes to access data about a Participant, BoZ will require a written instruction from the Participant’s Authorised Person or certified copy of a board resolution of that Participant authorising the auditors, BoZ or this other legal entity to access data about that Participant. The audit trails provide information:
a) at application level, showing the path of transactions through the system, the source of all changes to data in the system files and on the databases and providing proof that all transactions received have been processed. The data entry users and approvers for all actions are recorded and are visible on the relevant screens; b) at Participant level, showing details of all transactions relating to a particular Participant; c) at User level, giving a record of all accesses to the system and the actions of Users, keeping a record of actions by User and showing which Users have taken action on any particular transaction. These elements form part of the technical audit trail known as the system log; d) at technical level, providing a secure record of the technical functioning of the system, recording access to system modules and technical events in detail. This audit trail is referred to as the system log. The main audit tools, apart from standard reports, are as follows:
a) facility to list all transactions for ZIPSS from on-line history files within the system for at least the previous three years, from postings on the database; b) facility to request from BoZ User defined reports for audit purposes based on statistical and other tables in the database.

Upon receiving any notification under b), BoZ will promptly make enquiries of the Participant in respect of which insolvency is reported to be suspected and, if the relevant Participant is prudentially supervised by an entity other than BoZ, the relevant supervisor. To the extent that an Insolvency Event is admitted by the relevant Participant and that fact is communicated to BoZ, BoZ shall promptly notify all other Participants.

For Participants that still have an account with BoZ after the occurrence of an Insolvency Event, BoZ will take all reasonable steps to ensure that, except with the consent of the appointed trustee, no further Payment Instructions are presented to ZIPSS for Settlement by the insolvent Participant with BoZ, except for NSI transactions. The suspended or excluded Participant remains however bound by the obligations resulting directly or indirectly from its participation in ZIPSS.

Insolvency Proceedings
In accordance with the National Payments Systems Act, the relevant court, which, according to Zambian law, takes the decision of opening an insolvency proceeding against a Participant, shall immediately notify that decision to BoZ.

Bank of Zambia ZIPSS Rules
23.5 Notification of the decision marking the commencement of insolvency
proceedings at the end of the operating day
If the order or decree marking the commencement of insolvency proceedings occurs after the daily closing but before the beginning of the next Business Day, BoZ shall make the necessary adaptations in ZIPSS before the start of the next Business Day. If this concerns a Participant, BoZ shall adjust the parameters of ZIPSS so that the Participant in question can no longer issue or receive Payment Instructions (i.e. the Participant status is set as Blocked or Disabled in the system). The Participant shall be advised of the Insolvency Event before the start of the next Business Day.
23.6 Suspension or termination on grounds other than an Insolvency
Event

1.0 Risk Management
The parties will conduct their affairs and their relationship with one another and with the other participants in the utmost good faith and integrity in such manner as to minimise any risk of loss inherent in participation in the inter-bank clearing and settlement arena, whether such risk arises before, during or after the clearing and settlement processes. To this end, each party will:-

parties, and to avoid settlement failure;
ii. manage its liquidity in such a manner that will not adversely affect the liquidity of other
participants by ensuring prompt settlement of all its settlement obligations;
iii. promptly and diligently adhere to and implement risk reduction measures as required
by BoZ from time to time
iv. ensure the integrity, compliance and functionality of all of its systems, including
hardware, software, human resources and data received and transmitted into ZIPSS, and in particular ensure that such modifications and improvements are made to its systems as may be required to enable compliance with new developments in risk management and risk containment as and when they become available and are adopted by the Bank.
2.0 Business Continuity Planning
Each party will ensure and herewith undertakes that it will develop, introduce and maintain an effective and practical business continuity plan, relevant to systems and procedures, records, audit trails, recovery procedures and human resources, in order to ensure the effective continuity of its participation in ZIPSS notwithstanding any fact, matter or thing which might, but for such continuity plan, have jeopardised such party’s continued participation in ZIPSS and/or its ability to honour its obligations pursuant to such participation.
3.0 Disaster Recovery
Each party warrants and undertakes that: -
i. its systems and facilities are adequate to operate the transactions as required by the BoZ

Bank of Zambia ZIPSS Rules

of its systems and facilities as well as backup systems and facilities relevant to the settlement transactions on an annual basis as part of its annual audit, and will allow such auditors to make their report available to the Settlement Provider and to answer such reasonable requests for additional information as the Settlement Provider and/or its auditors may require.
