TLT ended the week on the back foot — the brief bear capitulation documented in Monday's note has stalled, with short interest edging back up and the ETF dropping another 1.2% to close at $82.25, now down nearly 5% over the past month.
The positioning picture has partially reversed from where Monday's note left off. Short interest nudged higher on Thursday to 92.7 million shares after touching a near-term low of 92.1 million on Tuesday — a modest rebuild, but notable because it interrupts what had been a clean unwind from the 100-million-share peak seen in mid-July. At 16.7% of free float, the short position remains well below the consolidation band of 17.8–17.9% that held through July 17–22, so the broader deleveraging trend is still intact. What has changed is the borrow market: availability has tightened meaningfully over the week, pulling back from a high of 793% on July 28 to 607% by Thursday. That is still comfortably loose by any absolute measure — roughly six idle shares for every one borrowed — but the direction of travel matters. The ORTEX short score has also crept back up to 57.2 after bottoming near 55.7 mid-week, suggesting the near-term bearish conviction that briefly softened is finding a second wind.
Options traders are not adding to the alarm. The put/call ratio has drifted toward its most call-skewed level in recent weeks, closing the week at 0.66 — slightly below its 20-day average of 0.68 and a full 0.15 points below the 52-week high of 0.81. A z-score of -0.71 puts current positioning in neutral territory: neither a defensive pile-on nor an aggressive bullish lean. The options market appears to be watching rather than positioning, which reinforces the sense that the week's moves are driven by macro rate developments rather than any fresh structural view on long-duration Treasuries.
Institutional flow offers a mixed read on underlying conviction. The most recent 13F disclosures show Bank of America trimming nearly 24.8 million shares and Citigroup cutting 9.9 million, while Barclays shed 4.2 million. On the other side, BlackRock added 2.2 million and BMO Asset Management built a 4.9 million-share position. The net picture is institutional distribution at the margin — the banks reducing duration exposure while asset managers add selectively. Northwestern Mutual remains the largest disclosed holder at 44.4 million shares (8.9% of outstanding), a position that has grown modestly and acts as a long-term demand anchor against the short-side pressure.
Cost to borrow remains almost irrelevant to the thesis. At 0.45%, borrowing costs are fractionally higher than a week ago but still near their lowest levels of the past 30 days. There is no friction discouraging new shorts, which means if macro catalysts push bears back toward the 100-million-share level seen in mid-July, the lending market will not stand in the way.
The week's setup is therefore cleaner than Monday's note suggested it might be: the deleveraging has paused rather than reversed, the price is drifting lower, and borrow costs give bears no reason to cover. The next move in TLT will likely be determined less by positioning mechanics and more by the trajectory of long-end yields — making the next Treasury auction and any Fed communication the data points most worth tracking.
