The approval of perpetual futures contracts in the US may expose traders to unforeseen tax and regulatory uncertainty if these products are ultimately deemed to be swaps rather than futures, a concern voiced by CME Group Chairman and CEO Terry Duffy. In an interview, Duffy highlighted the ambiguity surrounding the tax perspective for US participants, emphasizing that the consequence of this ambiguity is not being discussed. The comments come as CME continues its legal challenge against the Commodity Futures Trading Commission (CFTC) regarding the regulator's approval of perpetual futures contracts. The core issue revolves around whether perpetual futures should be legally categorized as futures or swaps, with Duffy arguing they should be classified as swaps due to the periodic funding payments exchanged between long and short positions.

Unlike traditional futures, perpetual contracts do not expire and involve periodic funding payments to keep the derivative's price aligned with the underlying asset, a mechanism Duffy believes satisfies the statutory definition of a swap under US law. If perpetual contracts are deemed swaps, they would be taxed under 'ordinary' taxation, as opposed to the blended tax treatment available for futures under Section 1256 of the US tax code. Given the novelty of perpetual futures, the IRS has not provided specific guidance on their tax treatment, potentially leading to uncertainty for market participants if the classification of these contracts changes. Legal experts, such as Rustin Diehl and Jason Gottlieb, note 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 resolution of this issue may depend on court interpretations, especially considering the Supreme Court's decision in Loper Bright, which reduced the deference given to agencies' interpretations of ambiguous statutes. The process is expected to be lengthy, with potential litigation and the need for separate guidance from the IRS, underscoring the uncertainty faced by large institutions in reporting trades involving perpetual futures.
