Sustainable Fund Returns Lag Peers' in Second Half of 2024

Sustainable funds hit a record AUM of $3.56 trillion but posted a median return of 0.4%, compared to traditional funds’ 1.7%.

Key Takeaways

  • Sustainable funds underperformed traditional funds in the second half of 2024 for the first time since the first half of 2022.
  • However, assets under management (AUM) in sustainable funds grew to a new high of $3.56 trillion as of December 31, 2024.
  • This was due to a slight recovery in flows during the last six months of the year, with net inflows of $30.6 billion in the second half of 2024, following a weak second quarter.

Sustainable funds lagged traditional funds in 2024,  according to a new "Sustainable Reality" report1 from the Morgan Stanley Institute for Sustainable Investing. After outperforming in the first half of the year, sustainable funds underperformed in the second half for the first time since the first half of 2022, delivering H2 2024 median returns of 0.4%, compared to traditional funds’ 1.7%.2

Some of the relative underperformance in the second half stemmed from sustainable funds’ market exposure. Seventy percent of sustainable funds invest either in Europe or globally, compared to just 41% of traditional funds which have more exposure to the Americas and Asia-Pacific (APAC). Sustainable funds’ skew to global and European markets is not new, but in the second half of 2024, both Americas and APAC investment regions outperformed global and Europe investment areas, unlike in prior periods in which weak returns in APAC offset stronger returns in the Americas. The sustainable funds that do invest in the Americas or APAC outperformed traditional funds in those regions.

Over a longer period, sustainable funds have outperformed traditional funds. Institute analysis of Morningstar data found that investing a hypothetical $100 into a sustainable fund in December 2018 would equate to $136 today, while investing $100 into a traditional fund over the same period would equate to $131 today.

Assets Reach New High While Market Share Declines

Sustainable funds’ AUM reached a record of $3.56 trillion at the end of 2024, an increase of 0.9% since June 2024 and 4.8% since December 2023. However, the share of sustainable funds’ AUM as a portion of total AUM declined, falling to 6.8% in 2024 from 7.3% at the end of 2023. The decline mostly reflects stronger ongoing inflows into traditional funds.

A Mixed Picture for Sustainable Fund Flows

In 2024, sustainable fund inflows totaled $54.7 billion, just over half of the $100+ billion in new assets added in both 2023 and 2022. Trends improved as the year progressed though, with outflows in the second quarter followed by net inflows of $30.6 billion in the second half of 2024.

Regional fund flows varied. On an absolute basis, Europe-domiciled sustainable funds had the most inflows, with $32.3 billion in the second half of 2024, compared to $4.5 billion for Asia-domiciled funds.  North America-domiciled funds saw outflows of $6.3 billion, which marked nine consecutive quarters of outflows in the region.

By contrast, funds investing in the Americas—even if they were not domiciled there—had the strongest inflows in absolute terms at $14.5 billion, followed by funds investing globally at $7.3 billion and funds investing in Europe at $5.8 billion.
