World crop yields as the Department of Agriculture publishes them, with the listed thresholds drawn at the year each contract settles. The record is solid up to the last marketing year that has closed and dashed after it, because the department publishes a figure for a year still under way and revises it until that year ends, which is the number the market is pricing. Drag across a chart’s history to fit a straight line and project it forward with the year it would cross each threshold; different windows give different projections. Double-click to clear. Hover the series for the value at a point and its ten-year change, or a marker for the contract’s quote; click a marker to open that contract on IBKR.
