In December 2022, the OEE launched an index to measure the performance of French households’ financial savings.

The methodology is based on traditional methodology used for the calculation of stock indices and has been developed in consultation with Banque de France and AFG (both founding members of the OEE). All the source data used are publicly available and come from either Banque de France or France Assureurs.

The index is calculated quarterly by IEM Finance, an independent research firm specializing in the design, management and calculation of stock market indices, and is released on the third Thursday of March, June, September and December. The index is calculated under the sole responsibility of the OEE and does involve the member institutions’ one.

OEE index measuring the performance of French households’ financial savings should allow:

• to highlight the contribution of each asset class to global performance of households’ financial savings;
• to raise awareness of the importance of additional long-term saving in a context of ageing population and reform of public pay-as-you-go pension schemes;
• to raise awareness of the importance of diversification in an environment of rising inflation and interest rates.

Over the last 10 years :

• the average annual performance of the index was 2.08%;
• equity products contributed more than half of performance (54%), while their weighting in the index averaged 20%;
• there have been twelve quarters (from^Q1 2018 to ^Q2 2019,^Q1 2020 and every quarter since 2022) during which annual index growth was below inflation;
• changes in the weight of each asset class in households’ portfolio remain small ones and therefore have few impact on global performance of the index
