Operational Risk

The risk of loss from inadequate or failed internal processes, people, systems, or from external events. It excludes strategic and reputational risk but includes legal risk.

Related: Basel II Definition of Operational Risk, Legal Risk, Risk Event Taxonomy
Basel II Definition of Operational Risk

The internationally adopted wording that treats operational risk as losses from process, people, system and external-event failures, explicitly including legal risk while excluding strategic and reputational risk.

Related: Operational Risk, Legal Risk
Legal Risk

Loss arising from contracts that cannot be enforced, lawsuits, regulatory penalties, or adverse court rulings. Under the Basel definition it sits inside operational risk rather than beside it.

Related: Operational Risk, Compliance Risk
Compliance Risk

The exposure to fines, sanctions, or loss of licence from failing to follow laws, regulations, or internal conduct standards. Many banks treat it as a sub-category of operational risk.

Related: Legal Risk, Regulatory Reporting Risk
Risk Event Taxonomy

A structured hierarchy of loss types, such as internal fraud, external fraud, employment practices, client mishandling, physical damage, system failure, and execution errors, used to classify incidents consistently.

Related: Loss Data Collection, Operational Risk
Risk and Control Self-Assessment (RCSA)

A workshop-based process in which business owners identify their risks, rate likelihood and impact, and judge whether existing controls reduce exposure to an acceptable level.

Related: Control Effectiveness, Key Risk Indicator, Residual Risk
Key Risk Indicator (KRI)

A quantitative measure, such as failed trades, system downtime, or staff turnover, tracked against thresholds to give early warning that an operational risk is rising.

Related: Risk Appetite, Risk and Control Self-Assessment (RCSA), Loss Data Collection
Loss Data Collection

The systematic capture of internal loss events and near misses with amounts, causes, and business lines, used to calibrate models, size capital, and identify control gaps.

Related: Risk Event Taxonomy, Near Miss, External Loss Data
External Loss Data

Loss information drawn from other institutions, public reports, or pooled industry consortia, helping a bank learn from events it has not itself suffered.

Related: Loss Data Collection, Scenario Analysis
Near Miss

An incident that could have caused a loss but did not, either by luck or because a control caught it. Recording near misses reveals weaknesses before real damage occurs.

Related: Loss Data Collection, Control Effectiveness
Residual Risk

The level of risk left after existing controls are applied. It is compared with risk appetite to decide whether further mitigation is required.

Related: Inherent Risk, Risk and Control Self-Assessment (RCSA), Control Effectiveness
Inherent Risk

The exposure that would exist if no controls were in place. Assessing it separately from residual risk shows how much protection the control framework actually provides.

Related: Residual Risk, Control Effectiveness
Control Effectiveness

The degree to which a designed control actually prevents, detects, or corrects the risk it targets in practice, tested through evidence rather than assumed from documentation.

Related: Residual Risk, Key Control, Control Testing
Key Control

A control that is essential to keeping a material risk within appetite, so that its failure would directly expose the bank to significant loss or regulatory criticism.

Related: Control Effectiveness, Control Testing
Control Testing

Planned checks, through sampling, re-performance, or observation, that confirm a control operates as described and produces reliable evidence over a defined period.

Related: Key Control, Control Effectiveness, Three Lines Model
Three Lines Model

A governance structure where business units own and manage risk, a risk and compliance function oversees it, and internal audit provides independent assurance to the board.

Related: Operational Risk Function, Control Testing, Internal Audit
Operational Risk Function

The second-line team that sets operational risk policy, aggregates risk information, challenges business assessments, and reports the consolidated profile to senior management.

Related: Three Lines Model, Chief Risk Officer, Risk Appetite
Chief Risk Officer (CRO)

The senior executive accountable for the bank's enterprise-wide risk framework, including operational risk, with sufficient independence to challenge business lines.

Related: Operational Risk Function, Risk Appetite, Board Risk Committee
Board Risk Committee

A board sub-committee that approves risk appetite, reviews the top operational risks and material incidents, and oversees whether management is addressing weaknesses.

Related: Risk Appetite, Chief Risk Officer (CRO), Operational Risk Function
Risk Appetite

The amount and type of risk the board is willing to accept in pursuit of strategy, usually expressed through qualitative statements and quantitative tolerances for specific risks.

Related: Risk Tolerance, Key Risk Indicator (KRI), Residual Risk
Risk Tolerance

The concrete, measurable limit that translates a broader risk appetite statement into thresholds, such as a maximum number of failed settlements per month.

Related: Risk Appetite, Key Risk Indicator (KRI)
Risk Register

A living inventory of identified risks, each with an owner, cause, potential impact, existing controls, and current rating, used to track and prioritise treatment.

Related: Risk and Control Self-Assessment (RCSA), Risk Owner, Residual Risk
Risk Owner

The named individual accountable for managing a specific risk and its controls, including monitoring indicators and escalating when exposure moves outside appetite.

Related: Risk Register, Three Lines Model
Scenario Analysis

A forward-looking exercise that imagines plausible severe events, estimates their likelihood and impact, and tests whether controls and capital would withstand them.

Related: External Loss Data, Stress Testing, Operational Risk Capital
Stress Testing

Applying extreme but plausible conditions to a portfolio or process to see how losses, liquidity, and controls behave beyond normal operating experience.

Related: Scenario Analysis, Business Continuity Planning
Operational Risk Capital

The amount of regulatory or economic capital set aside to absorb unexpected operational losses, calculated under approaches such as the standardised or basic indicator method.

Related: Scenario Analysis, Loss Data Collection, Operational Risk
Business Continuity Planning

Preparedness that lets critical operations keep running or recover quickly after disruption, covering alternate sites, systems, staff, and supplier arrangements.

Related: Business Impact Analysis, Disaster Recovery, Stress Testing
Business Impact Analysis

A study identifying critical business functions, their dependencies, and the maximum tolerable downtime, which sets the recovery objectives for continuity planning.

Related: Business Continuity Planning, Recovery Time Objective
Recovery Time Objective (RTO)

The maximum acceptable time to restore a process or system after disruption. It drives investment in backup capability and is validated through testing.

Related: Business Impact Analysis, Disaster Recovery
Disaster Recovery

The technical arrangements, such as backup data centres and failover systems, that restore IT services after a failure or outage.

Related: Business Continuity Planning, Recovery Time Objective (RTO)
Outsourcing Risk

Exposure arising when a third party performs activities for the bank, including service failure, data loss, concentration on one vendor, and weakened oversight.

Related: Third-Party Risk Management, Concentration Risk, Service Level Agreement
Third-Party Risk Management

The process of due diligence, contracting, monitoring, and exit planning applied to vendors and service providers so their failures do not damage the bank.

Related: Outsourcing Risk, Service Level Agreement, Concentration Risk
Service Level Agreement (SLA)

A contract clause defining measurable service standards, such as uptime or processing time, plus remedies when the provider misses them.

Related: Third-Party Risk Management, Outsourcing Risk
Concentration Risk

Exposure that builds up because too much activity, data, or dependency sits with one counterparty, system, or geography, so a single failure has outsized effect.

Related: Outsourcing Risk, Third-Party Risk Management
Internal Fraud

Loss caused by staff acting dishonestly, such as theft, unauthorised trading, or collusion with outsiders, often hidden by circumventing segregation of duties.

Related: External Fraud, Segregation of Duties, Risk Event Taxonomy
External Fraud

Loss caused by outsiders, including forgery, card skimming, cyber intrusion, and fraudulent loan applications, often exploiting weak authentication controls.

Related: Internal Fraud, Cyber Risk, Risk Event Taxonomy
Cyber Risk

The chance of loss from attacks or failures affecting information systems, including data breaches, ransomware, and unauthorised access to customer accounts.

Related: External Fraud, IT Risk, Business Continuity Planning
IT Risk

Exposure from technology failure, obsolescence, or change, covering outages, processing errors, inadequate capacity, and poorly managed system upgrades.

Related: Cyber Risk, Disaster Recovery, Change Management Risk
Change Management Risk

The danger that a new system, product, or process introduces errors, outages, or control gaps because testing, approval, or rollback planning was inadequate.

Related: IT Risk, New Product Approval
Segregation of Duties

Splitting tasks so no single person can initiate, authorise, record, and reconcile a transaction, reducing both error and the opportunity for concealment.

Related: Internal Fraud, Key Control
Execution, Delivery and Process Management Risk

Loss from failed transaction processing, documentation errors, missed deadlines, or data entry mistakes in day-to-day operations and settlement.

Related: Risk Event Taxonomy, Settlement Risk, Key Risk Indicator (KRI)
Settlement Risk

The chance that a transaction fails to settle as expected, leaving the bank exposed to counterparty default, funding gaps, or market moves before completion.
