Investment Policy Statement (IPS)

An investment policy statement (IPS) is a written document that records how a pool of money is to be invested and supervised. It states the investor's return objectives and tolerance for risk, the constraints that apply, the target asset allocation and permitted investments, the benchmarks used to judge results and who is responsible for each decision. Pension schemes, endowments, foundations, insurers, companies investing surplus cash and private clients working with an adviser all use them.

An IPS is a governance tool rather than a trading plan. It gives a board, trustees or an individual a stable reference point that guides managers and prevents decisions being made on impulse in volatile markets. It is often required or expected by regulators and, for those acting as a fiduciary, helps show that investments were chosen through a prudent, documented process.

Before a long road trip, a family might agree some ground rules: where they are going, how fast they are willing to drive, how much they can spend, and who decides on detours. When an argument breaks out halfway, they look back at the rules rather than starting from scratch.

An investment policy statement is those ground rules for money. It says what the money is for, how much ups and downs the owner can live with, what kinds of investments are allowed and how success will be measured. Advisers and managers then work within the rules, and the owner can check whether they did.

• Purpose and scope. The assets covered, their purpose and the parties involved, such as trustees, an investment committee, managers and custodians.
• Return and risk objectives. A required or target return, often stated after inflation and costs, and the level of risk or maximum loss the investor accepts.
• Constraints. Liquidity needs, time horizon, tax position, legal and regulatory limits, and any ethical or other special preferences.
• Asset allocation. Target weights and permitted ranges for each asset class, plus rules for rebalancing when weights drift.
• Permitted investments and limits. Allowed instruments, minimum credit ratings, concentration and counterparty limits, and rules on leverage, derivatives and currency hedging, including any currency overlay.
• Monitoring and review. The benchmarks, reporting frequency, performance review process and how often the IPS itself is reviewed, often yearly.

For pension funds, the IPS links investment strategy to the liabilities the scheme must pay, and may set rules for hedging interest rate and inflation risk in a defined benefit pension plan. For an endowment fund or foundation, it reconciles a spending rule with the goal of preserving purchasing power for future generations. For individuals, an IPS agreed with a portfolio manager or adviser captures goals such as retirement income and helps the client stay with the plan during downturns.

Companies use a treasury IPS for excess cash investment. Its priorities are usually preservation of capital first, then liquidity, then yield, and it lists permitted instruments, such as bank deposits, money market funds, treasury bills and commercial paper, together with maturity and counterparty limits for the company's short-term investment portfolio.

Requirements vary by country and investor type. In the United Kingdom, trustees of most occupational pension schemes must prepare a statement of investment principles under the Pensions Act 1995, covering matters such as risk, expected return, the kinds of investments held and their approach to financially material considerations. In the United States, guidance from the Department of Labor treats a written statement of investment policy as consistent with the fiduciary duties of plan fiduciaries under ERISA, and fiduciaries are expected to follow it. Professional bodies, including the CFA Institute, publish guidance on what an institutional IPS should contain. As of November 2026, many investors also add sections on stewardship and sustainability in response to disclosure rules.

An IPS is only useful if it is specific, realistic and followed. Statements that are vague, copied from templates or never reviewed give little guidance, while ones that are too rigid can force poor decisions when conditions change. Targets for return and risk may conflict, and an IPS cannot remove market risk; it can only make the choices behind a portfolio clear, consistent and open to review. Good practice is to revisit it after major changes in the investor's circumstances, in addition to routine reviews.
