SGOV: Shorters Retreat as Borrow Demand Eases

SGOV, the iShares 0-3 Month Treasury Bond ETF, enters the final days of October with short sellers pulling back sharply and the borrow market sitting at its loosest in weeks.

The clearest story this week is the retreat in short positioning. Shares sold short fell 14.7% over the past week, dropping to roughly 6.1 million shares. That follows a period of elevated activity through mid-October, when short interest briefly climbed toward 7.9 million shares. For an ETF of this size, a $116 billion market cap anchored to near-riskless 0-3 month Treasuries, even that peak was a modest absolute level. The retreat confirms that whatever tactical use was being made of SGOV borrows, whether as a hedge or a cash-management tool, that demand has abated.

Borrow conditions reflect the same looseness. Availability is running at roughly 1,537%, meaning there are more than fifteen shares available to borrow for every one currently lent out. That is well above the tightest point in the past 52 weeks, when availability dropped to around 60%. Cost to borrow has eased to 0.52%, down about 3% on the week and 2% over the past month, levels that classify as low by any standard. The contrast with late September is notable: on September 30, the lending pool tightened sharply, with availability collapsing to 169% and utilisation running near two-thirds of available supply. That episode has fully unwound.

Options positioning has nudged slightly more defensive this week, though the move is modest rather than alarming. The put/call ratio has risen to 0.60, about 1.7 standard deviations above its 20-day average of 0.56. For context, the 52-week low on the PCR was 0.10 and the high was 0.68, so the current reading sits in the upper range but well short of its most defensive extreme. For a Treasury bill ETF, the options market is rarely where the interesting signals sit; the move is worth noting but does not materially change the picture.

SGOV's price itself offers little drama by design. The ETF closed at $100.68, up a fraction on the day and barely changed on the week. Monthly distributions have been running near $0.30 per share, consistent with three-month Treasury yields. The most recent dividend, declared in September, paid out $0.3005 in October. That steady income stream is the product investors are buying, not price appreciation, and the data bears that out.

The main thing to watch from here is whether the mid-October uptick in short interest, which briefly pushed borrowed shares close to 7.9 million, reasserts itself around month-end or quarter-end positioning cycles, given that prior availability squeezes have clustered around those calendar points.
