Chicago SRW Wheat Futures (ZW) Contract Specifications
What you're trading
The CBOT Wheat future (ZW) gives you exposure to 5,000 bushels of Soft Red Winter (SRW) wheat with physical delivery. SRW wheat is grown primarily in the eastern U.S. and is used for pastries, crackers, and flat breads. ZW is the most globally oriented of the major grain futures — wheat pricing reflects a wide field of exporters (U.S., Russia, EU, Canada, Australia, Ukraine, Argentina) competing for global buyers. That makes ZW sensitive to geopolitical events (particularly around the Black Sea), weather in multiple growing regions, and currency moves across exporter countries.
