Basel II's A few Approaches to Operational Threat Management
Izvor: KiWi
The operational risk specifications of Basel II proposes 3 measurement methodologies for calculating the operational danger cash fees. These are typically the basic Indicator Technique, the Standardized Technique as well as the Highly developed Measurement Technique.
Underneath the fundamental Indicator Strategy financial institutions must hold funds for operational possibility equivalent to the ordinary in excess of the former 3 many years of a preset share (15% for this solution) of positive annual gross revenue (figures in regard of any calendar year where annual gross cash flow was adverse or zero are excluded).
While no distinct conditions are set out to be used on the Primary Indicator Method, banking institutions applying this technique are encouraged to comply with the Committee's steerage on "Sound Procedures for your Management and Supervision of Operational Risk" (BIS; February 2003). These concepts need:
oA hands on tactic in the creation of an ideal hazard management environment,
oPositive steps while in the identification, evaluation, checking and control of operational risk,
oAdequate general public disclosure.
Under the Standardized Technique a bank's things to do are divided into eight small business traces. In just every single business enterprise line, gross income is often a wide indicator that serves like a stand-in to the stage of company operations and thus the possible size of operational chance publicity inside each individual of such organization traces. The money demand for each business line is calculated by multiplying gross income by a factor (known as the "beta") assigned to that enterprise line. The beta serves for a substitute to the industry-wide romantic relationship among the operational chance decline expertise for a given business line as well as mixture stage of gross earnings for that enterprise line. The organization traces along with the beta factors range from 12% for "retail banking", "asset management" and "retail brokerage"; 15% for "commercial banking" and "agency services" to 18% for "corporate finance", "trading & sales" and "payment & settlement".
The total capital cost is calculated as the three-year average with the simple summation from the regulatory cash fees across each individual on the organization lines in each individual yr. In any specified yr, a negative funds charges (like a result of detrimental gross income) in any enterprise line may offset constructive money expenses in other enterprise traces without limit.
At national supervisory degree, the supervisor can choose to allow a bank to use the Alternative Standardized Approach (ASA) provided the bank is able to satisfy its supervisor that this alternative technique provides an improved basis for measurement of risks. Less than the ASA, the operational danger cash charge/methodology is the same as with the Standardized Technique except that two company traces - "retail banking" and "commercial banking" where a set aspect 'm' - replaces gross profits as the publicity indicator and is related for the extent of loans granted in these areas.
Beneath the Superior Measurement Techniques (AMA) the regulatory funds requirement equals the hazard measure generated by the bank's internal operational hazard measurement system working with unique quantitative and qualitative criteria. Utilization of the AMA is subject to supervisory approval.
Supervisory approval has to be conditional on the bank being able to show into the satisfaction on the supervisory authority that the allocation mechanism for these subsidiaries is correct and can be supported empirically. The quantitative standards that apply to internally generated operational threat measures for purposes of calculating the regulatory minimum money demand are that any internal operational chance measurement system must be consistent with the definition of operational threat and a range of defined loss event types (covering all operational aspects such as fraud, employee techniques, workplace safety, enterprise methods, processing techniques, enterprise disruption and reduction of physical assets).
To qualify for use in the State-of-the-art Measurement Techniques (AMA), a bank need to satisfy its supervisor that,
oThe banking companies board of directors and senior management, are actively involved from the oversight from the operational hazard administration framework;
oThe bank has an operational risk administration system that is conceptually audio and which includes an independent operational hazard administration function that is responsible to the design and implementation of the bank's operational chance administration framework;
oThe bank has It has sufficient resources to use this technique while in the major business enterprise lines as well as the manage and audit areas.
A bank employing the AMA will be subject to a period of initial monitoring by its supervisor before it can be used for regulatory purposes. This period will allow the supervisor to determine if the technique is credible and appropriate. The bank's internal measurement system will have to be able to reasonably estimate unexpected losses based on the combined usage of internal and relevant external loss data, scenario analysis and bank-specific enterprise surroundings and internal manage components.
The bank's measurement system ought to also be capable of supporting an allocation of economic cash for operational threat across business enterprise traces in a manner that creates incentives to improve enterprise line operational danger administration.
Additionally,
oThe operational possibility management function is responsible for documenting policies and procedures concerning operational danger management and controls, designing and implementing the bank's operational danger measurement methodology, designing and implementing a risk-reporting system for operational hazard, and developing strategies to identify, measure, monitor and control/mitigate operational threat,
oThe bank's internal operational chance measurement system need to be closely integrated into the day-to-day danger administration processes on the bank and its output have to be an integral part on the process of checking and controlling the bank's operational hazard profile. This information will have to play a major role in hazard reporting, administration reporting, internal funds allocation, and threat analysis.
oOperational threat exposures and reduction encounter must be reported regularly to company unit administration, senior management, and for the board of directors.
oThe bank's operational possibility administration system must be well documented plus the bank will have to have a routine in place for ensuring compliance with a documented established of internal policies, controls and procedures concerning the operational hazard management system, which will have to include policies for your treatment of noncompliance issues.
oInternal and/or external auditors should perform regular reviews on the operational danger management processes and measurement systems. This review must include both the actions on the organization units and with the independent operational danger administration function.
oThe validation of your operational hazard measurement system by external auditors and/or supervisory authorities have to include the verification that the internal validation processes are operating in a satisfactory manner; and making sure that data flows and processes associated together with the risk measurement system are transparent and accessible. In particular, it is necessary that auditors and supervisory authorities are in a position to have easy access, whenever they judge it necessary and less than acceptable procedures, for the system's specifications and parameters.
Because the analytical techniques for operational hazard continue to evolve the solution or distributional assumptions used to generate the operational chance measure for regulatory funds purposes is not being specified by the Basel Committee. A bank need to however be able to show that its strategy captures potentially severe 'tail' decline events. Irrespective with the strategy is used, a bank must demonstrate that its operational chance measure meets a soundness standard comparable to that in the internal ratings-based strategy for credit possibility.
Based on this, bank supervisors will involve the bank to calculate its regulatory cash requirement as the sum of expected decline (EL) and unexpected loss (UL), unless the bank can demonstrate that it is adequately capturing EL in its internal organization methods (to base the minimum regulatory funds requirement on UL alone, the bank have to be able to demonstrate to your satisfaction of its national supervisor that it has measured and accounted for its EL exposure).
A bank needs to have a credible, transparent, well-documented and verifiable tactic for weighting these standard elements in its overall operational possibility measurement system.
Internal decline data is critical to linking a bank's danger estimates to its actual loss practical experience. Such data is most relevant when it is clearly linked to a bank's current organization pursuits, technological processes and risk management procedures. To do this a bank have to have documented procedures for assessing the on-going relevance of historical loss data, including those situations where judgment overrides or other adjustments may be used, to what extent they may be used and who is authorized to make such decisions. Internally generated operational chance measures used for regulatory funds purposes have to be based on a minimum five-year observation period of internal reduction data. However, when the bank first moves into the AMA, a three-year historical data window is acceptable.
To qualify for regulatory money purposes, a bank's internal loss collection processes must be able to map its historical internal reduction data into the relevant supervisory categories as are defined in detail from the Basel II Annexes. The bank will have to have documented objective conditions for allocating losses to the specified organization lines and event types. A bank's internal decline data have to be comprehensive. It need to capture all material pursuits and exposures from all acceptable sub-systems and geographic locations. The bank have to be able to justify that any excluded routines or exposures, both individually and in combination would not significantly impact the overall possibility estimates. This should be based on an acceptable minimum gross reduction threshold for internal reduction data collection. Additionally, a bank should collect information relating the date in the event, any recoveries of decline amounts, as well as descriptive information about the drivers or causes on the decline event. The extent of detail in any descriptive information should be correct to the dimensions from the gross decline amount.
Operational threat losses that are related to credit hazard and have traditionally been included in banks' credit hazard databases (e.g. collateral management failures) should continue to be treated as credit possibility for your purposes of calculating minimum regulatory funds. It follows that such losses will not be subject for the operational hazard money demand. Nevertheless, for the purposes of internal operational chance administration, banks will have to identify all material operational risk losses consistent together with the scope from the definition of operational threat and also the defined event types, including those related to credit chance.
A bank's operational chance measurement system ought to use pertinent external data (either public data and/or pooled business data), especially when there is any possibility to believe that the bank is potentially exposed to severe losses, however infrequent. Additionally a bank ought to use scenario analysis of expert opinion in conjunction with external data to evaluate its exposure to high-severity events.
