A SIPS operator shall establish a comprehensive framework to manage liquidity risks posed by the SIPS's participants, settlement banks, nostro agents, custodian banks, liquidity providers and other relevant entities. The SIPS operator shall provide the participants with adequate tools to effectively manage their liquidity and shall monitor and facilitate the smooth flow of liquidity in the system.

A SIPS operator shall put in place operational and analytical tools which enable it to identify, measure and monitor settlement and funding flows, including the use of intraday liquidity, on an ongoing and timely basis.

A SIPS operator shall hold, or ensure that participants hold, sufficient liquid resources at all times as from the moment financial obligations are established, in all currencies in which it operates, to effect same-day settlement of financial obligations in a wide range of potential stress scenarios. Where appropriate, this shall include intraday or multiday settlement. The stress scenarios shall include: (a) the default, under extreme but plausible market conditions, of the participant which, together with its affiliates, has the largest aggregate financial obligation; and (b) other scenarios in accordance with paragraph 11.

A SIPS operator settling two-sided payments, or one-sided payments in currencies other than euro, shall hold, or ensure that participants hold, sufficient liquid resources, in accordance with paragraph 3, in the ways referred to in paragraph 5.

Where a SIPS operator supplements the resources referred to in paragraph 3 with other assets, these assets shall be likely to be marketable or acceptable as collateral (for, e.g., lines of credit, swaps, or repos) on an ad hoc basis following a default, even if this cannot be reliably prearranged or guaranteed under extreme but plausible market conditions. Where a participant supplements the resources referred to in paragraph 3 with other assets, the SIPS operator shall ensure that these other assets meet the requirements set out in the first sentence of this paragraph. Assets shall be presumed to be likely to be marketable or acceptable as collateral if the SIPS operator has taken into account the rules and practices of the relevant central bank on the eligibility of collateral.

A SIPS operator shall not assume that emergency central bank credit will be available.

A SIPS operator shall carry out due diligence to verify that each provider of the SIPS's liquid resources, as referred to in paragraph 3: (a) has sufficient and up-to-date information to understand and to manage the liquidity risks associated with the provision of cash or assets; and (b) has the capacity to provide cash or assets as required. The SIPS operator shall review its compliance with the due diligence obligation at least annually. Only entities with access to credit from the central bank of issue shall be accepted as liquidity providers. The SIPS operator shall regularly test the SIPS's procedures for accessing its liquid resources.

A SIPS operator with access to central bank accounts, payment services or securities services shall use these services, where practicable.

A SIPS operator shall, through rigorous stress testing, determine the amount and regularly test the sufficiency of its liquid resources to satisfy the requirements under paragraphs 3 and 4. In conducting stress testing, the SIPS operator shall consider a wide range of relevant scenarios, including one or more participant defaults on the same day and on two or more subsequent days.

When such scenarios are considered, the design and operation of the SIPS shall be taken into account and all entities that might pose material liquidity risks to the SIPS shall be examined, including settlement banks, nostro agents, custodian banks, liquidity providers and linked FMIs. Where appropriate, the scenarios shall cover a multiday period.

A SIPS operator shall document its reasons for holding, and shall have appropriate governance arrangements relating to, the cash and other assets maintained by it or by participants. It shall establish clear procedures for reporting the results of its stress tests to the Board and shall use these results to evaluate the adequacy of and make adjustments to its liquidity risk-management framework.
