Sovereign wealth funds in the post-pandemic era

Abstract

Sovereign wealth funds (SWFs) have over $11.5 trillion in assets under management as of February 2023. Most of these 176 funds are sponsored by non-Western countries and their growth has made SWFs important international investors, particularly in private equity funding. We first define SWFs, then discuss their evolution into today’s categories of stabilization, savings, and development/strategic funds. We discuss the documented importance of SWF funding sources – oil sales revenues versus excess reserves from export earnings – and summarize the empirical literature studying how SWFs allocate funds geographically and across asset classes. Next, we summarize empirical evidence on the impact of SWF stock investments on target firm financial and operating performance and discuss the evidence showing that the announcement of SWF investment causes target firm stock prices to rise in the short term, but the positive impact is significantly less than the positive return following large stock purchases by private investors, and the longer-term effect of SWF investment on target firms is generally negative. SWFs’ recent focus on promoting ESG policies of investee companies is assessed and briefly compared to the effectiveness of other institutional investors’ ESG efforts.
