10Y Treasury — Commitment of Traders

10-Year Treasury Note futures trade on the CBOT in $100,000 face-value contracts and are the most liquid interest rate futures market in the world. COT positioning in 10Y Treasuries is the definitive institutional read on duration and yield expectations. When speculators (primarily hedge funds and macro traders) are heavily net short the 10Y, they are positioned for rising yields; net longs imply expectations of falling rates or recession-driven flight to safety. The COT Index for 10Y Treasuries is one of the most powerful risk signals in the entire COT dataset: extreme speculative net shorts have historically coincided with yield peaks, and extreme net longs have marked rate lows. Commercial positioning (banks, broker-dealers using futures for hedging balance sheet duration) provides the structural counterflow. During Fed tightening cycles, the spec short position builds persistently; when the Fed pivots, the unwind can be dramatic. Weekly changes in the 10Y Treasury COT are a leading indicator of the bond market's directional bias and complement duration positioning data from institutional fund surveys.
