On January 6, 2020 we are launching options on the 3-Month SOFR futures (SR3). This will include standard options and Mid-Curves.

We will list serial, quarterly, and select weekly options.  There will be a January option listed on day-one that expires January 10, 2020.

SOFR options were designed to closely mimic Eurodollar options in terms of listings, strike increments, and the ability to create spreads between the different products (SOFR with SOFR and SOFR with Eurodollars)

There are two significant differences:

1. The expiration date of the Quarterly SOFR option (SR3) is different than the Quarterly ED option, and;
2. The expiring quarterly option will result in a futures position that doesn’t expire at the same time as the option

To elaborate:

When do the options expire?

All SOFR options, including the quarterly option will expire on the Friday before the 3^rd Wednesday of the named contract month.  The 2:00 pm CST futures settle will determine if an option is in or out of the money.  You may trade the options on Globex until 4:00 pm CST.

The quarterly expiration is one fundamental difference between SR3 and ED options

• The quarterly SR3 options will expire on the Friday before the third Wednesday.  The 2 p.m. CST. futures settle will determine if the option is in or out of the money. You may trade the option on Globex until 4 pm CST
• The quarterly ED option expires at 11:00 a.m. London time on the second London bank business day immediately preceding the third Wednesday of the contract’s named month of delivery (typically, the Monday before the third Wednesday).

What are the underlying futures of the quarterly SOFR options (SR3)?

SR3 quarterly options will exercise into their named SR3 futures contract, for example the March 2020 option will expire on Friday, March 13, 2020. Exercised and assigned options will result in a March 2020 futures position.  The March 20 future doesn’t expire until June 16, 2020

This is the second fundamental difference between SR3 and ED options

• The quarterly SR3 options will result in a futures position that still has 3 months until expirations
• The quarterly ED options results in a futures position that expires at the same time as the ED options

What are the underlying futures of the quarterly serial SOFR options (SR3) and Mid-Curves?

Just like the Eurodollars, SR3 serial options will result in a futures position in the next quarterly SR3 future. For example, the April 2020 SR3 option (SR3J0) will result in a June SR3 future (SR3H0).

Just like the Eurodollars, the Mid-Curve options will result in a deferred futures position that expires from 1 to 5 years after the options expires.

Just like ED options, strikes will be listed in .25 underlying instrument price points from 5.50 above to 5.50 below at-the-money. Additionally, strikes will be listed in .125 underlying instrument price points from 1.50 points above to 1.50 points below at-the-money.
