25.2
Instruments comprise financial instruments, foreign exchange (FX), and commodities. A financial instrument is any contract that gives rise to both a financial asset of one entity and a financial liability or equity instrument of another entity. Financial instruments include both primary financial instruments (or cash instruments) and derivative financial instruments. A financial asset is any asset that is cash, the right to receive cash or another financial asset or a commodity, or an equity instrument. A financial liability is the contractual obligation to deliver cash or another financial asset or a commodity. Commodities also include non-tangible (ie non-physical) goods such as electric power.

25.10
Banks are allowed to deviate from the presumptive list specified in RBC25.9 according to the process set out below.6
(1)
If a bank believes that it needs to deviate from the presumptive list established in RBC25.9 for an instrument, it must submit a request to its supervisor and receive explicit approval. In its request, the bank must provide evidence that the instrument is not held for any of the purposes in RBC25.5.
(2)
In cases where this approval is not given by the supervisor, the instrument must be designated as a trading book instrument. Banks must document any deviations from the presumptive list in detail on an on-going basis.
1 Footnote
25.11
Notwithstanding the process established in RBC25.10 for instruments on the presumptive list, the supervisor may require the bank to provide evidence that an instrument in the trading book is held for at least one of the purposes of RBC25.5. If the supervisor is of the view that a bank has not provided enough evidence or if the supervisor believes the instrument customarily would belong in the banking book, it may require the bank to assign the instrument to the banking book, except if it is an instrument listed under RBC25.6.
25.12
The supervisor may require the bank to provide evidence that an instrument in the banking book is not held for any of the purposes of RBC25.5. If the supervisor is of the view that a bank has not provided enough evidence, or if the supervisor believes such instruments would customarily belong in the trading book, it may require the bank to assign the instrument to the trading book, except if it is an instrument listed under RBC25.8.
25.13
A bank must have clearly defined policies, procedures and documented practices for determining which instruments to include in or to exclude from the trading book for the purposes of calculating their regulatory capital, ensuring compliance with the criteria set forth in this section, and taking into account the bank’s risk management capabilities and practices. A bank’s internal control functions must conduct an ongoing evaluation of instruments both in and out of the trading book to assess whether its instruments are being properly designated initially as trading or non-trading instruments in the context of the bank’s trading activities. Compliance with the policies and procedures must be fully documented and subject to periodic (at least yearly) internal audit and the results must be available for supervisory review.
25.14
Apart from moves required by RBC25.5 through RBC25.10, there is a strict limit on the ability of banks to move instruments between the trading book and the banking book by their own discretion after initial designation, which is subject to the process in RBC25.15 and RBC25.16. Switching instruments for regulatory arbitrage is strictly prohibited. In practice, switching should be rare and will be allowed by supervisors only in extraordinary circumstances. Examples are a major publicly announced event, such as a bank restructuring that results in the permanent closure of trading desks, requiring termination of the business activity applicable to the instrument or portfolio or a change in accounting standards that allows an item to be fair-valued through P&L. Market events, changes in the liquidity of a financial instrument, or a change of trading intent alone are not valid reasons for reassigning an instrument to a different book. When switching positions, banks must ensure that the standards described in RBC25.5 to RBC25.10 are always strictly observed.
1 FAQ
25.15
Without exception, a capital benefit as a result of switching will not be allowed in any case or circumstance. This means that the bank must determine its total capital requirement (across the banking book and trading book) before and immediately after the switch. If this capital requirement is reduced as a result of this switch, the difference as measured at the time of the switch will be imposed on the bank as a disclosed Pillar 1 capital surcharge. This surcharge will be allowed to run off as the positions mature or expire, in a manner agreed with the supervisor. To maintain operational simplicity, it is not envisaged that this additional capital requirement would be recalculated on an ongoing basis, although the positions would continue to also be subject to the ongoing capital requirements of the book into which they have been switched.
1 FAQ
25.16
Any reassignment between books must be approved by senior management and the supervisor as follows. Any reallocation of securities between the trading book and banking book, including outright sales at arm's length, should be considered a reassignment of securities and is governed by requirements of this paragraph.
(1)
Any reassignment must be approved by senior management thoroughly documented; determined by internal review to be in compliance with the bank's policies; subject to prior approval by the supervisor based on supporting documentation provided by the bank; and publicly disclosed.
(2)
Unless required by changes in the characteristics of a position, any such reassignment is irrevocable.
(3)
If an instrument is reclassified to be an accounting trading asset or liability there is a presumption that this instrument is in the trading book, as described in RBC25.9. Accordingly, in this case an automatic switch without approval of the supervisor is acceptable.
2 FAQs
25.17
A bank must adopt relevant policies that must be updated at least yearly. Updates should be based on an analysis of all extraordinary events identified during the previous year. Updated policies with changes highlighted must be sent to the appropriate supervisor. Policies must include the following:
(1)
The reassignment restriction requirements in RBC25.14 through RBC25.16, especially the restriction that re-designation between the trading book and banking book may only be allowed in extraordinary circumstances, and a description of the circumstances or criteria where such a switch may be considered.
(2)
The process for obtaining senior management and supervisory approval for such a transfer.
(3)
How a bank identifies an extraordinary event.
(4)
A requirement that re-assignments into or out of the trading book be publicly disclosed at the earliest reporting date.
25.18
An internal risk transfer is an internal written record of a transfer of risk within the banking book, between the banking and the trading book or within the trading book (between different desks).
25.19
There will be no regulatory capital recognition for internal risk transfers from the trading book to the banking book. Thus, if a bank engages in an internal risk transfer from the trading book to the banking book (eg for economic reasons) this internal risk transfer would not be taken into account when the regulatory capital requirements are determined.
25.21
When a bank hedges a banking book credit risk exposure or equity risk exposure using a hedging instrument purchased through its trading book (ie using an internal risk transfer),
(1)
The credit exposure in the banking book is deemed to be hedged for capital requirement purposes if and only if:
(a)
the trading book enters into an external hedge with an eligible third-party protection provider that exactly matches the internal risk transfer; and
(2)
The equity exposure in the banking book is deemed to be hedged for capital requirement purposes if and only if:
(a)
the trading book enters into an external hedge from an eligible third-party protection provider that exactly matches the internal risk transfer; and
(b)
the external hedge is recognised as a hedge of a banking book equity exposure.
(3)
External hedges for the purposes of RBC25.21(1) can be made up of multiple transactions with multiple counterparties as long as the aggregate external hedge exactly matches the internal risk transfer, and the internal risk transfer exactly matches the aggregate external hedge.
1 Footnote
25.22
Where the requirements in RBC25.21 are fulfilled, the banking book exposure is deemed to be hedged by the banking book leg of the internal risk transfer for capital purposes in the banking book. Moreover both the trading book leg of the internal risk transfer and the external hedge must be included in the market risk capital requirements.
25.23
Where the requirements in RBC25.21 are not fulfilled, the banking book exposure is not deemed to be hedged by the banking book leg of the internal risk transfer for capital purposes in the banking book. Moreover, the third-party external hedge must be fully included in the market risk capital requirements and the trading book leg of the internal risk transfer must be fully excluded from the market risk capital requirements.
25.24
A banking book short credit position or a banking book short equity position created by an internal risk transfer8 and not capitalised under banking book rules must be capitalised under the market risk rules together with the trading book exposure.
1 Footnote
25.25
When a bank hedges a banking book interest rate risk exposure using an internal risk transfer with its trading book, the trading book leg of the internal risk transfer is treated as a trading book instrument under the market risk framework if and only if:
(1)
the internal risk transfer is documented with respect to the banking book interest rate risk being hedged and the sources of such risk;
(2)
the internal risk transfer is conducted with a dedicated internal risk transfer trading desk which has been specifically approved by the supervisor for this purpose; and
(3)
the internal risk transfer must be subject to trading book capital requirements under the market risk framework on a stand-alone basis for the dedicated internal risk transfer desk, separate from any other GIRR or other market risks generated by activities in the trading book.
1 FAQ
25.26
Where the requirements in RBC25.25 are fulfilled, the banking book leg of the internal risk transfer must be included in the banking book’s measure of interest rate risk exposures for regulatory capital purposes.
25.27
The supervisor-approved internal risk transfer desk may include instruments purchased from the market (ie external parties to the bank). Such transactions may be executed directly between the internal risk transfer desk and the market. Alternatively, the internal risk transfer desk may obtain the external hedge from the market via a separate non-internal risk transfer trading desk acting as an agent, if and only if the GIRR internal risk transfer entered into with the non-internal risk transfer trading desk exactly matches the external hedge from the market. In this latter case the respective legs of the GIRR internal risk transfer are included in the internal risk transfer desk and the non-internal risk transfer desk.
25.28
Internal risk transfers between trading desks within the scope of application of the market risk capital requirements (including FX risk and commodities risk in the banking book) will generally receive regulatory capital recognition. Internal risk transfers between the internal risk transfer desk and other trading desks will only receive regulatory capital recognition if the constraints in RBC25.25 to RBC25.27 are fulfilled.
1 FAQ
25.29
The trading book leg of internal risk transfers must fulfil the same requirements under RBC25 as instruments in the trading book transacted with external counterparties.
25.30
Eligible external hedges that are included in the credit valuation adjustment (CVA) capital requirement must be removed from the bank’s market risk capital requirement calculation.
1 FAQ
25.31
Banks may enter into internal risk transfers between the CVA portfolio and the trading book. Such an internal risk transfer consists of a CVA portfolio side and a non-CVA portfolio side. Where the CVA portfolio side of an internal risk transfer is recognised in the CVA risk capital requirement, the CVA portfolio side should be excluded from the market risk capital requirement, while the non-CVA portfolio side should be included in the market risk capital requirement.
25.32
In any case, such internal CVA risk transfers can only receive regulatory capital recognition if the internal risk transfer is documented with respect to the CVA risk being hedged and the sources of such risk.
25.33
Internal CVA risk transfers that are subject to curvature, default risk or residual risk add-on as set out in MAR20 through MAR23 may be recognised in the CVA portfolio capital requirement and market risk capital requirement only if the trading book additionally enters into an external hedge with an eligible third-party protection provider that exactly matches the internal risk transfer.
25.34
Independent from the treatment in the CVA risk capital requirement and the market risk capital requirement, internal risk transfers between the CVA portfolio and the trading book can be used to hedge the counterparty credit risk exposure of a derivative instrument in the trading or banking book as long as the requirements of RBC25.21 are met.
