Risk budget

Allocate the portfolio's permitted risk across strategies and exposures in line with objectives, liquidity and loss capacity.

Quick answer

A risk budget defines how much portfolio risk may be taken and how that risk is allocated among strategies, asset classes or exposures. It converts return objectives and risk capacity into measurable limits and monitoring triggers, using metrics suited to the portfolio.

Use the worked example

Meaning and transaction use

An SEC-filed prospectus defines a risk budget as the permitted range of portfolio deviations from benchmarks across sector, country, security selection and duration, then allocates it to component strategies. [S1]

Another SEC filing describes a diversified risk budget measured by each investment's contribution to total portfolio volatility. [S2]

Proposed control method: pair modelled risk contributions with liquidity, concentration, drawdown and scenario limits.

Worked example

Illustrative modelled risk allocation only. Assume total portfolio risk units of 100, allocated 35 to public equity, 25 to private investments, 20 to credit, 10 to real assets and 10 to diversifiers.

Scroll the table horizontally to view all columns.

Measure	Calculation	Result
Growth risk	35 + 25	60 units
Defensive risk	20 + 10	30 units
Diversifier risk	Given	10 units
Private-investment share	25 / 100	25.0%

The illustrative budget allocates 60 risk units to growth exposures and 25.0% of total modelled risk to private investments.

Proposed transaction review process

Set objectives

Define return need, loss capacity, horizon and liquidity.

Choose measures

Select volatility, drawdown, scenario, leverage and liquidity metrics.

Allocate risk

Assign budgets to asset classes, strategies and decision owners.

Monitor and rebalance

Track contributions, breaches, model drift and scenario outcomes.

Evidence checklist

Objectives

Spending, liabilities, horizon and return requirements.

Portfolio

Positions, valuations, leverage, liquidity and currencies.

Model

Volatility, correlations, scenarios and assumptions.

Governance

Limits, owners, frequency, breaches and remediation.

Decision framework

Situation	Proposed action
A component exceeds budget	Reduce, hedge or approve a documented exception.
Correlations rise	Refresh portfolio risk and stress tests.
Private valuations lag	Use scenarios and liquidity measures alongside reported volatility.
Family needs change	Reset objectives and the approved risk allocation.

Common errors to check

Treating asset weights as risk contributions.
Relying on one model.
Ignoring illiquidity and leverage.
Leaving breach actions undefined.

Set the portfolio risk budget

Bring objectives, holdings and scenario assumptions to a risk-budget review. Reconcile modelled risk, liquidity and loss capacity.
