Sovereign Pension and Social Security Reserve Funds: a portfolio analysis

Sovereign wealth funds (SWFs) have been increasing in numbers and in the global reach of their investment activities. At the same time, they seem to experience the adverse consequences of the financial crisis differently than other financial intermediaries. This paper assesses whether and how a retirement-financing purpose has affected their investment strategies since the global financial crisis, as opposed to the strategies of other public pension entities that do not operate as SWFs. We construct a sample of 12 sovereign pension reserve funds (SPRFs) and social security reserve funds (SSRFs) and analyze the effects of size, operational model, country development, the fund's experience, and quality of disclosures on strategic asset allocation for the period 2007\u20132014. We also investigate the relevance of \u201chome bias.\u201d Our results show that SPRFs invest more aggressively than SSRFs, but are less exposed to domestic investments. We do not find major shifts in asset allocation induced by the financial crisis, except for a recent decrease of home-country exposures
