CFTC Whistleblower Fund Improvement Act of 2023 This bill makes modifications to the Commodity Futures Trading Commission Customer Protection Fund. The fund is used for whistleblower awards and customer education initiatives and is financed by monetary sanctions for commodities law violations. First, the bill raises the cap on the amount allowed to be deposited into the fund. The bill also permanently extends the availability of amounts set aside in an account for customer education initiatives and administrative expenses of the Commodity Futures Trading Commission's Office of Customer Education and Outreach and the Whistleblower Program. Currently, any amount remaining in this account as of October 1, 2024, must be returned to the fund.
