USO has risen 7.2% this week to $128.85 — and the short-covering story that defined the previous two weeks has abruptly reversed course, with shorts rebuilding and the borrow market tightening to near-emergency levels.
The pivot is sharp and notable. The previous note documented a sustained unwind that had cut short interest from roughly 130% of float in mid-June down to 83.7% by July 15. That covering trade has now stalled and turned. Short interest climbed 19% on the week to reach 100.8% of float — meaning estimated short positions once again exceed the entire free float. That compares to just under 84% a week ago. The daily data makes the timing clear: shorts have added steadily each session from July 14 through July 21, rebuilding positions even as the price pushed higher. Whether this reflects fresh bearish conviction on crude, or mechanical hedging activity from the fund-dominated holder base, the directional signal is unambiguous — new short pressure is entering even as USO rallies.
The borrow market has tightened in lock-step, and the speed of the move deserves attention. Availability has collapsed from 108% on July 17 to just 0.17% today — effectively zero. That means virtually every share in the lending pool is now lent out. For context, availability was at a comfortable 286% as recently as July 7. The week-on-week deterioration is 99%. Cost to borrow more than doubled over the week to 5.66%, after sitting at just 2.17% on July 14. The combination of near-zero availability and a cost-to-borrow more than 160% above last week's level puts the borrow market in a similar position to the late-June stress episode, when availability hit zero on June 19 and remained critically tight through June 26. On those prior occasions, the squeeze in the lending market coincided with volatile price swings in both directions — a pattern worth noting, not extrapolating.
Options positioning has shifted in a direction that contrasts with the short rebuild. The put/call ratio has eased to 1.04, well below its 20-day average of 1.27 and running nearly 1.8 standard deviations below that mean. For most of June, the PCR sat above 1.5 — heavy demand for downside protection that tracked USO's decline. The sharp drop in put demand this week, even as shorts rebuild and borrow tightens, suggests the options market and the lending market are telling different stories. Options traders have rotated away from defensive hedges. Short sellers are adding exposure. These two signals are pointing in opposite directions, and the tension between them is the clearest read on where sentiment currently sits.
The ownership picture adds useful context. Goldman Sachs and Morgan Stanley together hold over 69% of reported shares — a concentration that reflects USO's role as a trading and hedging vehicle for institutional desks rather than a buy-and-hold position. Brevan Howard entered a new 11.5% position in the March quarter. Jane Street and CIBC also built material new stakes. The holder base is overwhelmingly composed of broker-dealers, hedge funds, and arbitrage desks — exactly the participants most likely to be behind the rapid oscillations in short positioning. The ORTEX short score of 70.6 reflects the elevated bearish pressure, up from 67.2 on July 9 and now approaching the range it occupied during the peak short-stress period of mid-June.
What to watch next: whether the borrow market at near-zero availability forces another involuntary covering episode similar to late June, or whether the options market's easing put demand proves the better read on where crude prices and USO are heading over the next few sessions.
