Next contracts

Futures contracts expire, so a trader who wants to keep a position must close the expiring contract and open the next one: the roll. For 30-Year U.S. Treasury Bond (ZB) the current front contract is ZBZ26, with a last trading day of 21 Dec 2026 and a first notice day of 30 Nov 2026. The next contract is ZBH27.

The exchange rule we apply for ZB: Last trade: 7th business day before the last business day of the contract month. First notice: last business day of the month before. ZB is physically delivered: holding a position into the delivery period can create an obligation to make or take delivery, which is why speculative traders normally close or roll before the first notice day or last trading day.

The suggested roll date of 25 Nov 2026 is a convention, not an exchange rule. It is set a little before the first notice or last trading day, because liquidity moves to the next contract and many brokers require positions to be closed or rolled before then. Dates are calculated from the exchange's rules and its holiday calendar. The exchange calendar is the authority.

Roll convention: Suggested roll: 2 business days before the earlier of first notice day and last trade. A convention, not an exchange rule; brokers may require earlier exit. Exchange calendar: https://www.cmegroup.com/markets/interest-rates/us-treasury/30-year-us-treasury-bond.calendar.html
