What these terms mean
The 30-Year U.S. Treasury Bond futures contract (ZB) is listed on Chicago Board of Trade. One contract represents $100,000 face value, and prices are quoted in points and fractions of a point (1 point = 1% of par). The minimum price movement, or tick, is 1/32 of a point (0.03125), worth $31.25 per contract. A move of one full point is therefore worth $1,000 per contract, and every profit, loss and margin figure for ZB scales from those two numbers.
ZB is listed for these contract months: Mar (H), Jun (M), Sep (U), Dec (Z). 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 rollover page lists the next expiries and the dates that matter for each.
The values on this page come from the exchange's own contract specification and were last checked on 27 Oct 2026. Exchanges amend contract terms from time to time, most often trading hours and tick sizes. Where a value here disagrees with the exchange, the exchange is right; the methodology page explains how each field is checked, and any field we have not confirmed against the exchange is marked on this page.
