This topic describes expected use cases for the CME Treasury Rules-based Offset Engine, RBOE, which is used to build offsetting positions in Fixed Income Clearing Corporation (FICC)/CME Cross-margin Allocation Process. Eligible products for risk offset between CME and FICC will need to be moved into designated position accounts within CME Clearing. This content covers both a manual approach and an automated approach for position transfers via the CME Optimizer software. This content is considered a draft for discussion purposes. This content is supplemental to normal Optimizer release notes.

Please see Optimizer release notes for additional details on release scope.

Background

CME Group and FICC are working together to enhance the capital efficiencies available to our common members (and their affiliates, where applicable) when trading U.S. Treasury Securities and CME interest rate futures that have offsetting risk exposures. For the avoidance of doubt, this content refers to the FICC Cross-margin arrangement within the Background section but subsequently refers to all CME operational workflows as the Treasury Rules-based Offset Engine or RBOE. This can be used interchangably with RBOE.

Proposed Methodology

Key Enhancements Planned

• Introduce active management aspect applicable to CME positions; passive management remains for FICC positions.
• Expand the eligibility of interest rate futures products available for cross-margining

Timeline to Delivery:

• Target Production Date: Pending Regulatory Approval

Eligibility:

• Eligibility for the arrangement remains house (proprietary) accounts of CME Clearing Members & FICC GSD Netting Members, however, subject to regulatory analyses and approvals, CME & FICC are supportive of extending this program beyond house accounts as part of a later phase

Glossary of Terms

• Treasury rules-based offset engine (RBOE): term used to define the operational offset process at a high level. Can be used synonymously with CME / FICC offset process.
• Target allocation: the allocation of CME futures selected to offset FICC cash treasuries as defined in Equivalent Position Report. Conversion of treasury cash to CME futures applied via DV01. Represented in FutAllocQty field in the equivalent position report.
• FICC position account: This account is new for the CME/FICC Cross Margin Program and is the account which contains CME eligible interest rate futures positions that will available to offset the FICC treasury cash positions. Clearing firms can move positions into this account by performing transfers in FEC+ (manual or API) or by running the RBOE within the Optimizer software. Firms may also give up or directly execute into this account. All positions margined in this account are subject to 3-day MPOR margin treatment.
• Portfolio Margin (PM) position account: existing trading account containing offsets to cleared IRS positions. Clearing firm, via manual process or Optimizer software, transfers or directly executes into this account to achieve offsets using 5-day MPOR. Not all participants of RBOE offsets participate in this account structure.
• Futures and Options position account: existing trading account capturing all futures and options positions not allocated to a special function trading account per above. Margined via 1-day or 2-day MPOR in SPAN® margin methodology.

  FICC Positions Report

• Users of Optimizer also must generate a new positions input file expressing positions only residing in the FICC position account or account mapping details, should no positions exist. This file is very similar to the existing positions.csv file format Optimizer uses but has been customized for FICC position representation. Users will also need to use the positions.csv file to represent futures positions that are not in FICC position account.
  Filename convention:

• Producer of file: Clearing Firm
  • If using manual process described below in 4.1, disregard this file.
• File location: clearing firm back office
• Filename convention: FICCPositions.csv is the default filename pattern, though users can amend the filename manually in the Optimizer's configuration.json file (found in the Optimizer's Plugins directory).
• File Format:

  FileSpecification FileSpecification

  Comma-delimited Value (CSV)
• Special use: when no positions are present in a FICC position account (for instance on the first day of using the program), users must specify a line item for each FICC position account defining indexes 0 – 6 and 18 below. All others are blank (null, not 0). This line item is used by Optimizer as an account definition.

• Examples of the new FICCPositions file is available in the Optimizer's \[local dir\]\Samples.

  RBOE Allocation Offset Workflow

  Clearing firms can, as always, directly execute trading activity in the new FICC position account. This action assumes the Clearing Firm's trading strategy evaluates potential offsets to be realized against cash treasury positions in the FICC position account prior to execution. Note all positions in the FICC position account during ITD and EOD margin settlement cycles will be margined using the SPAN Methodology calibrated to 3-day Margin Period of Risk to meet regulatory requirements. Clearing Firms should only move risk offsetting positions into the FICC positions account.
  Users of the rules-based offset engine have two alternative integration methods to achieve treasury offsets:

  Clearing Firm Manual Process

  One option for Clearing Firms to realize treasury offsets is to consume a new file produced by CME, the XMFICCPOSN file described above, then use their a standard BAU process to give-up/transfer positions from the normal futures and options trading account to the FICC position account. BAU give-up/transfer processes include direct transfer entry in the Front End Clearing (FEC+) user interface or programmatically via existing message queues. Positions in the FICC position account during ITD and EOD margin settlement cycles will be used to offset treasury cash positions defined in a new position file shared between CME and DTCC at regular intervals throughout the business day.
  The target allocation of positions which should be allocated in the FICC position account is available in the FutAllocQty field by instrument and FICC margin account in the XMFICCPOSN file.
  Clearing Firms must use the available allocation from their books and records to satisfy, if possible, the target allocation. Note all standard firm regulatory reporting is required, no new open interest is to be created as a result of the new offsetting process.
  Note positions transferred to the FICC position account during prior day cycles will be retained in the FICC position account day over day, so a re-evaluation and re-establishment of the target allocation from the XMFICCPOSN file is necessary daily. In some cases the target allocation may be lower on T compared to T-1 and a transfer from the FICC position account back to the normal futures and options account would be expected.
  Here is an operational workflow:
  
  Workflow in depth:

1. Position data shared between FICC and CME (multiple times daily).
2. CME generates reports, including the Equivalent Position Report (XMFICCPOSN)
3. The Equivalent Position Report (XMFICCPOSN) is shared to firm secure FTP directories and picked up by Clearing Firms.
4. Clearing Firm runs internal process comparing target allocation to available allocation and identifies the offset to be achieved.
5. Transfers booked via standard BAU process.
