At launch, CME Group will offer predefined, non-implied spreads between each coupon and our 10-Year Treasury Note futures. The 30-Year UMBS TBA coupon will be the front leg of the spread. The 10-Year Note will be the back leg of the spread. Due to the similarity in contract sizes, spreading TBA futures and Treasury futures will be relatively easy and straightforward. Moreover, spread positions between TBAs and Treasuries, regardless of how they are executed, will be eligible for margin spread credits vs. 10-Year Note futures.

Here is a table of the current DV01s* and spread ratios and combinations that will be available at launch:

Correlation of 30-Year UMBS TBAs and select Treasury futures

Correlation of monthly returns for TBAs on 30-Year UMBS and Treasury futures provides a sense of the hedging and spreading relationships between them. At launch on November 7, 2022, the 30-Year UMBS TBA futures have a coupon stack of seven coupons ranging from 2.0% to 5.0%. The three nearby contracts were utilized in our TBA analysis with rolling contract months for the TBA coupons. For the Treasury futures, we applied the price of the rolling front month. 5-Year (FV), 10-Year (TY), Ultra 10-Year (TN) and Classic Bond (US) futures were used in our analysis. The 2% coupon has a two-year history (Jul-2020 through Sep-2022) due to it recently becoming active with the decline in mortgage rates (2020). All of the other coupons (2.5%, 3%, 3.5%, 4%, 4.5%, 5%) have a history of more than 10 years (Jan-2012 through Sep-2022).

Please refer to Table 1. (TY), Table 2. (FV), Table 3. (TN), and Table 4. (US) below for the correlation of monthly returns for these Treasury futures and the active contract months and coupons of TBAs on 30-Year UMBS.
