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. Duffy emphasized that there is ambiguity from a tax perspective for all US participants due to the lack of clarity on how the Internal Revenue Service (IRS) will tax these contracts. The comments were made amidst CME's ongoing legal challenge against the Commodity Futures Trading Commission (CFTC) over the regulator's approval of perpetual futures contracts in the US. The core issue revolves around whether perpetual futures should be legally treated as futures or swaps, with Duffy arguing that they should be classified as swaps due to the periodic funding payments exchanged between long and short positions, which he believes satisfies the statutory definition of a swap under US law.

If perpetual contracts are classified as futures, many institutional traders could receive a blended tax treatment, but if they are deemed swaps, they would be taxed under 'ordinary' taxation. However, the IRS has not issued specific guidance on the tax treatment of perpetual futures, leading to potential uncertainty for market participants. Legal experts note that the issue is complex, with the definition of swaps being extremely broad and the economic function of perpetual futures resembling that of traditional futures, making it a 'substance-over-form' question. The outcome of the court decision could significantly influence how the US approaches perpetual futures, with the potential for considerable litigation and the need for separate guidance from the IRS on tax treatment.
