ABSTRACT We conduct a meta‐literature review of safe haven and hedge assets covering 617 papers published in 170 sources from 1996 to 2022 based on the Scopus database. This review includes a qualitative analysis of the bibliometric content and a quantitative analysis of the citations to identify the primary research streams and offer future research directions. The analysis identifies four research streams in the hedge and safe haven literature: (1) Gold as a hedge and safe haven asset; (2) various models estimating the hedge and safe haven ability of potential assets such as precious metals, crude oil, and cryptocurrencies; (3) Bitcoin as a safe haven asset; and (4) the role of various safe haven assets, particularly Gold and Bitcoin, during the COVID‐19 crisis. The meta‐review also classifies the most influential authors focusing on hedging and safe haven research through co‐authorship and collaborative network analysis. Finally, future research directions are formulated with a wide set of potential research questions and areas. The outcomes of this meta‐review study are useful for researchers, financial analysts, and investors searching for the best safe haven assets during unfavorable market conditions.
