3-Month, 6-Month, and 9-Month SOFR Mid-Curve options bring greater flexibility to the front of the SOFR curve by offering short-dated monthly options on white quarterly SOFR futures.

Traditional yearly Mid-Curve options reference an underlying futures contract of the same named month, one to five years in the future.  For example, a December 2022 1-Year Mid-Curve that expired in December 2022 referenced a December 2023 SR3 futures contract.

Historically, when that December 2022 1-Year Mid-Curve expired there was no longer any short-dated options tied to the December 2023 futures contract. 3-, 6-, and 9-Month Mid-Curves were introduced specifically to address this gap, offering short-dated, one to three month options on the second, third, and fourth quarterly SOFR futures contracts.
