The approval of perpetual futures contracts in the US may lead to unforeseen tax and regulatory challenges for traders if these contracts are eventually deemed swaps rather than futures, a concern that has garnered little attention, warns CME Group Chairman and CEO Terry Duffy. In an interview, Duffy pointed out the ambiguity surrounding the tax implications for US participants. This uncertainty stems from an ongoing legal dispute between CME and the Commodity Futures Trading Commission (CFTC) regarding the classification of perpetual futures.

The outcome of this case could substantially influence the US approach to perpetual futures and how the Internal Revenue Service (IRS) taxes these contracts. The core issue revolves around whether perpetual futures should be legally categorized as futures or swaps, with Duffy arguing they should be considered swaps due to the periodic funding payments between long and short positions, which aligns with the statutory definition of a swap under US law. This distinction is crucial because if perpetual contracts are classified as futures, institutional traders might receive a blended tax treatment, whereas if they are deemed swaps, they would be subject to ordinary taxation. However, the IRS has not provided specific guidance on the tax treatment of perpetual futures, leaving market participants with uncertainty about how to report these positions.

Legal experts agree that the issue is complex, with the definition of swaps being broad and the economic function of perpetual futures resembling that of traditional futures. The Supreme Court's decision to eliminate the Chevron doctrine means that federal courts will now have more discretion in interpreting ambiguous statutes, potentially leading to a lengthy and complex litigation process. Ultimately, the tax treatment of perpetual futures may require separate guidance from the IRS, and until there is clarity from regulators, tax authorities, or the courts, large institutions may face uncertainty in reporting trades involving these contracts.
