I am reading CME Methodology for SOFR Future settlement calculation. The calculation seems to be straight forward but I am confused about the data CME uses for settlement price.

I am assuming it is using average SOFR prices published by newyorkFed T+1.

I was following the example outlined in SOFR Futures Settlement Calculation. I couldn't find the same SOFR benchmark rates in Fed.

  • $\begingroup$ I think the data in the document is fictional. It was built before futures traded. The FED published the first rate on April 3, 2018 (for April 2nd). The CME note also says its first trade date will be Monday, May 7, 2018. $\endgroup$

  • $\begingroup$ Neither EFFR nor OBFR (in your screenshot) is SOFR. SOFR itself is identical to the settlement values from the CME (look at the 3m SOFR future settlement file). $\endgroup$
