Guide to OECD Institutional Investors Statistics


The OECD Institutional Investors Statistics (IIS) provides a unique set of statistics that reflect the level and structure of the financial assets of institutional investors in the OECD countries and in the Russian Federation.  Institutional investors (investment funds, insurance companies and pension funds) are major collectors of savings and suppliers of funds to financial markets. They serve as financial intermediaries and have an impact on investment strategies.

In the OECD IIS, concepts and definitions are predominantly based on the System of National Accounts, data begin in 1980 and are derived from national sources. Indicators are presented as percentages of GDP allowing for international comparisons, and at country level, both in national currency and as percentages of total financial assets of the investor. 

Main Topics

The OECD IIS are presented in two datasets:

Institutional investors assets

This dataset presents financial and non-financial assets of institutional investors. Data are broken down by type of investor: open-end and closed-end investment funds, life and non-life insurance corporations, pension funds and other forms of institutional savings; and by type of asset: currency and deposits, securities, loans, shares and other equities, other financial assets, and non-financial assets. Assets are reported both in millions of national currency and in millions of US dollars, in current prices.

Institutional investors indicators

This dataset contains indicators on the financial assets of investment funds, insurance corporations and pension funds. For each of these three types of institutional investor, the indicators measure the total financial assets as percentage of GDP, as well as the various financial assets as percentage of the total financial assets.
