The approval of perpetual futures contracts in the US may lead to unforeseen tax and regulatory uncertainty for traders if these contracts 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 implications for US participants. The comments come as CME challenges the Commodity Futures Trading Commission's (CFTC) approval of perpetual futures contracts in the US, with the outcome potentially influencing the US approach to these rapidly growing financial products. A key point of contention is whether perpetual futures should be legally classified as futures or swaps, with Duffy arguing they should be considered swaps due to the periodic funding payments exchanged between long and short positions.

Unlike traditional futures, perpetual contracts do not expire and instead involve periodic funding payments to keep the derivative's price aligned with the underlying asset. Duffy believes this mechanism aligns with the statutory definition of a swap under US law.

The main issue with the current designation is that if perpetual contracts are deemed futures, institutional traders may receive a blended tax treatment, but if classified as swaps, they would be taxed under ordinary taxation. Given the novelty of perpetual futures, the IRS has not provided specific guidance on their tax treatment.

Legal experts consider the issue complex, with the definition of swaps being broad and the economic function of perpetual futures resembling that of traditional futures. The outcome will depend on the court's interpretation, potentially leading to a long and complex litigation process. Until there is clarity from regulators, tax authorities, or the courts, large institutions may face uncertainty in reporting trades involving perpetual futures, potentially leading to tax disputes.
