Unlisted securities stock loans are offered by lenders and can be used as collateral for a loan. In theory, any shareholder with a significant amount of capital tied up in a private business can use unlisted securities-based loans. However, it’s most seen with high-net-worth individuals and entrepreneurs who are shareholders in very successful private companies. Unlisted securities-based loans use securities in private companies as collateral that are usually looking to expand or move to a listed share market in the near future.
