Understanding how institutional investors operate enables a savvy investorto interpret capital flows in the financial markets and in private equity. However, their decisions should not be copied mechanically, as these organizations have constraints, resources, and investment horizons that differ from those of an individual investor.
Use in an Investment Strategy
Analyzing the behavior of institutional investors helps us understand a fund’s structure, market depth, and the criteria used to select an asset manager. It also helpsidentify the risk factors considered by professionals, such as liquidity, diversification, governance, and the alignment of assets with liabilities.
This observation is intended as an educational tool and is not an investment recommendation. Investing involves the risk of capital loss.
How does an institutional investor operate?
An organization that acts on behalf of beneficiaries
Unlike an individual investor, an institutional investor generally does not invest its own assets. It manages capital that has been entrusted to it or that corresponds to future obligations.
For example, an insurance company invests the premiums paid by its policyholders so that it can pay out claims and honor savings contracts. A pension fund invests the contributions it receives to finance future retirement benefits.
The institution must therefore build its portfolio by taking several factors into account:
- the duration of his commitments;
- the predictability of its disbursements;
- its liquidity needs;
- their risk tolerance;
- the applicable prudential rules;
- the objectives set by its governing body.
This practice is often referred to by the English term “asset-liability management.”
A scope that varies depending on the definition
There is no universally accepted definition of the term “institutional investor.” Its scope depends on statistical, legal, or economic conventions.
Broadly speaking, the OECD includes, among others, insurance companies, pension funds, and certain investment funds. Under a more restrictive French definition, banks and asset management companies may be distinguished from institutional investors.
An asset management firm, for example, manages portfolios on behalf of clients. It does not necessarily own the invested capital. A bank, on the other hand, engages in lending, deposit-taking, financing, and sometimes proprietary investing.
Who are the major institutional investors?
Insurance companies
Insurers are among the leading institutional investors in Europe. They invest the premiums they collect in bonds, stocks, real estate, infrastructure, and unlisted assets.
Their asset allocation depends on the nature of their obligations. A life insurer may have a relatively long investment horizon, but must maintain sufficient liquidity to meet policy surrenders and the benefits specified in the contracts.
Pension Funds and Retirement Organizations
Pension funds collect and invest contributions to finance retirement benefits. Their investment horizon can span several decades.
This time horizon allows themto consider investing in illiquid assets, provided they can manage capital calls and future cash flow needs.
According to the OECD’s *Pension Markets in Focus 2025* report, retirement assets totaled $69,800 billion at the end of 2024, of which $63,100 billion were held by pension funds and $6,700 billion by public reserve funds. These assets grew by 7.1% over the course of 2024.
Sovereign Wealth Funds
A sovereign wealth fund invests capital that belongs directly or indirectly to a government. Its resources may come from budget surpluses, foreign exchange reserves, or revenues from natural resources.
Its objectives may include capital preservation, diversification of government revenue, pension funding, or support for future generations. Its investment horizon is generally long-term, but its strategy depends on the mandate defined by the government.
Foundations and Endowment Funds
Foundations, universities, and endowment funds invest their assets to ensure the long-term financing of their missions. They seek a balance between preserving capital, generating income, and funding recurring expenses.
Some of these investors have a theoretically perpetual investment horizon. They can therefore allocate a portion of their portfolio to illiquid assets, provided that their annual needs remain covered.
How much influence do institutional investors have?
According to the Banque de France report *Financial Assets of Insurance Corporations in France, Q4 2025*, at the end of 2025, French insurers and pension funds held approximately 2,853 billion euros in financial assets. This estimate is based on the sum of the outstanding amounts published by the Banque de France for three institutional categories.
Calculation of shares: the amount in the category divided by 2,853.3 billion euros.
This table does not represent all French institutional investors. In particular, it excludes investment funds, public entities, foundations, and other entities that might fall under a broader definition of the term.
How do institutional investors structure their asset allocation?
Asset-Liability Management
The first step is to analyze the institution’s future obligations. Their amount, maturity, and degree of predictability determine the amount of liquidity that must be maintained.
An institution that anticipates annual disbursements of 100 million euros cannot tie up its entire portfolio for ten years. It must maintain liquid assets or sufficiently predictable cash flows to cover these expenses.
This line of reasoning distinguishes institutional investors from investors who base their decisions solely on an asset's expected return.
Strategic Allocation
Strategic asset allocation divides the portfolio among various asset classes: bonds, publicly traded stocks, real estate, infrastructure, private debt, private equity, and cash.
This breakdown depends, in particular, on:
- the investment horizon;
- the acceptable level of risk;
- liquidity needs;
- regulations;
- commitments to beneficiaries;
- the economic assumptions used.
The allocation is generally reviewed periodically. It is not adjusted solely in response to short-term market movements.
The Selection of Fund Managers
Institutional investors frequently entrust a portion of their capital to specialized investment management firms. In doing so, they evaluate the manager’s strategy, team, governance, control processes, and historical performance.
In private equity, the analysis also focuses on team stability, investment discipline, operational value creation, the management of conflicts of interest, and the terms for exiting investments.
Past performance is considered one indicator among others. It does not guarantee future results.
What role do they play in the economy?
Financing for Businesses and Governments
Institutional investors buy government bonds, finance companies, and invest in investment funds. In this way, they help channel savings toward the economy’s financing needs.
In public markets, they may hold significant stakes in large companies. In private markets, they provide capital to private equity, private debt, infrastructure, and real estate funds.
According to France Invest’s report, *French Private Equity Activity in 2025*, French private equity firms raised 42.9 billion euros in 2025, representing a 10% increase compared with 2024.
Part of this capital comes from French and international institutional investors.
Market Liquidity and Stability
Through the volume of their investments, institutional investors influence market liquidity. Their purchases and sales can affect prices, trading volumes, and financing conditions.
Their long-term investment horizon may reduce the need to sell in a hurry. However, a liquidity shock or a regulatory change could cause several institutions to reallocate their portfolios simultaneously, which could amplify certain market movements.
Corporate Governance
Shareholder institutions can vote at general meetings and engage with management. In particular, they influence matters such as board composition, executive compensation, climate strategy, and risk management.
This influence depends on their voting policies, the size of their holdings, and the mandate given to the management companies.
Why do they invest in private equity?
An investment horizon compatible with unlisted securities
A private equity fund can tie up capital for ten years or more. This time frame may align with the long-term commitments of certain insurers, pension funds, sovereign wealth funds, or endowment funds.
However, this compatibility is not automatic. The institution must model capital calls, future distributions, and scenarios in which outflows would be delayed.
A Different Approach to Diversification in Listed Markets
Private equity provides access to companies that are not publicly traded. It can therefore complement a portfolio consisting of publicly traded stocks and bonds.
This diversification remains imperfect. Unlisted companies are exposed to economic cycles, financing conditions, and changes in valuation. The infrequent nature of valuations may also give the impression of reduced volatility without eliminating the underlying economic risk.
Access to specialized managers
Institutions can build relationships with specialized management teams and analyze multiple generations of funds. In particular, they assess the consistency of the strategy, the dispersion of returns, realized losses, and the ability to support companies.
However, investing in a fund does not guarantee a specific return. Performance can vary significantly depending on the fund’s inception year, strategy, execution quality, and exit conditions.
What constraints govern their investments?
Prudential Rules
European insurers are subject, in particular, to the Solvency II framework. Its “prudent person” principle requires that assets be invested in a manner that ensures the safety, quality, liquidity, and profitability of the entire portfolio.
Article 132 of the directive also requires that assets not admitted to trading on a regulated market be maintained at prudent levels and that the portfolio be sufficiently diversified.
Liquidity Risk
Institutional investors must maintain sufficient capacity to pay out benefits, honor redemptions, and meet capital calls.
In private equity, commitments are not paid in full at the time of subscription. The fund manager gradually calls for capital. The institution must therefore set aside the necessary liquidity, even if distributions from other funds slow down.
Governance and Reporting
An institutional decision typically involves several levels of approval: the investment team, the risk committee, the investment committee, senior management, and sometimes the board of directors.
The institution must also document its assumptions, monitor risks, and produce financial, regulatory, and non-financial reports. This process explains why an institutional asset allocation may require several months of analysis before it is implemented.
History of Institutional Investors
1966 and 1967: Modernization of the French financing system
The Debré-Haberer reforms are contributing to the development of French financial markets. They encourage greater participation by financial institutions in corporate financing.
The 1980s and 1990s: Internationalization of Portfolios
Market liberalization and the growth of the asset management industry are facilitating geographic diversification. Pension funds, insurers, and investment funds are becoming major players in international markets.
The 2000s: Growth in Private Assets
Institutions are gradually increasing their allocations to infrastructure, real estate, private debt, and private equity. This trend is driven in particular by the desire for diversification and the long-term nature of certain investments.
2016: Solvency II took effect
The implementation of Solvency II further formalizes risk management at European insurers. Investments must be analyzed in terms of their impact on capital, liquidity, and solvency.
2024 and 2025: A Growing Financial Burden
According to the OECD, global assets set aside to fund pensions totaled $69,800 billion at the end of 2024. In France, insurers and pension funds held more than 2,850 billion euros in financial assets at the end of 2025.
These figures illustrate the structural role of institutional investors in the global allocation of capital.
