SLV enters October having shed 7.3% over the past month to $55.45, yet the past week has been nearly flat, down just 0.05%. The more interesting story is in the lending market, where short positioning is quietly rebuilding after a dramatic squeeze and unwind that played out through September.
The clearest sign of that rebuild is in short interest, which has climbed almost 9% week-on-week to 4.6% of the free float, reversing a sharp contraction from earlier in September. That contraction was striking: short interest peaked near 36.6 million shares around September 18, then collapsed to roughly 23.5 million by the final week of the month as the borrow market tightened severely. Availability told the story. Through September 10 to 14, the fund's lending pool was fully exhausted, with availability near zero and cost to borrow spiking to 1.23% on September 18, more than double where it runs today. That squeeze appears to have forced short covering. Now, with availability back to a relatively comfortable 171%, around 1.7 shares available for every one borrowed, new shorts are returning. Borrowing costs have fallen to 0.53%, down roughly 17% on the week and 22% over the month, reflecting a looser borrow environment. The 52-week availability low of 9.75% was hit during that September episode, a stark contrast to current conditions.
Options positioning adds a slightly bullish tilt to the picture. The put/call ratio has edged below its 20-day average, running at 0.43 against a mean of 0.45, placing it modestly below typical levels and well off the 52-week high of 0.85. That implies call demand is outpacing put demand relative to the recent norm, consistent with some residual bullish sentiment on silver. The z-score of negative 0.75 is not extreme, so this is a mild lean rather than a crowded positioning signal.
Institutional ownership is spread across a broad roster of financial intermediaries, none holding more than 2.5% of shares. Morgan Stanley tops the list with a 2.5% stake built through a meaningful addition in the June quarter, while Goldman Sachs added over 1.6 million shares in the same period. Jane Street, a significant market-making presence in ETF flows, trimmed its position by 2.15 million shares. The pattern across the top fifteen holders is more consistent with client demand routing and ETF arbitrage mechanics than with strong directional conviction from asset managers, which is typical for a large, liquid commodity ETF.
ORTEX's short score for SLV has nudged up to 52.6, a midpoint reading that has been hovering in a narrow band between 50 and 54 for the past two weeks. That lack of movement in the score mirrors the tug-of-war in the underlying data: short interest is rising again, but availability is ample and borrowing is cheap, so there is no structural pressure on existing shorts. The fund's official FINRA fortnightly figure, through September 15 settlement, showed 30.1 million shares short with 2.0 days to cover, a higher level than the current daily estimate, suggesting the covering since mid-September has been genuine rather than model noise.
The key dynamic to watch from here is whether silver prices hold near current levels while short interest continues to rebuild. A material move in spot silver in either direction, combined with the residual memory of September's near-total availability squeeze, would stress-test how quickly the borrow market tightens again from today's more relaxed starting point.
