This Is Not Your Grandfather’s Treasury Market. Hedge funds are now dominant players in the 10-year futures market, and their short is one of the largest on record. Bessent knows this. As of the September 29, 2026 report, leveraged funds were short 2.04 million contracts, about 36 percent of the market. The peak was 2.53 million contracts, roughly 45 percent of open interest, on August 26, 2025. The position has eased since then. It has not returned to normal. History makes the scale clear. Before 2023 this short rarely rose above 1 million contracts. In the 2008 crisis it reached only about 10 percent of the market. In the 2022 bond selloff it reached about 18 percent. From 2006 through 2021 it often switched between long and short and stayed far below today’s level. The old Treasury market was shaped mainly by banks, dealers, and long-term investors. The buildup that began in 2022 put hedge funds at the center: a larger and more persistent short than in prior cycles. That is concentrated exposure in the benchmark rate that prices mortgages, corporate debt, and government borrowing. Is this why the bond vigilantes are ignoring the data? A short this large does not need a fresh inflation print to keep yields high. It just needs the Fed to continue with its old flawed playbook. Now you can see why data that shows inflation declining is ignored and questioned. The position is already on, and a softer print is a threat to it. The other side is the unwind. If that crowd has to cover at once, a squeeze of historic proportions could follow, a rush to buy back a position bigger than anything seen in 2008 or 2022.
