You cannot use your CPF monies to purchase rights/warrants directly from the marketplace. However, if you are issued rights/warrants that arise from shares/investments that you currently hold, you may use your CPF monies to pay for the exercise price of these rights/warrants provided the underlying investments being taken up are included under the CPF Investment Scheme, subject to your available stock limit. For such cases, your agent bank will reach out to you on the details of the application.
