FXI shorts ease but remain extreme as borrow market loosens

Short interest in FXI, the iShares China Large-Cap ETF, has pulled back from a recent peak yet remains at levels that would look alarming on almost any other name in the market.

Short positions climbed steadily through October, reaching 41.4% of the free float as of October 20. That is down from 49.3% just four weeks ago, when a recent note flagged the reading as historic, but the one-month trend still shows a net 5.7% increase in shares short. Over the past week alone, short interest added another 3.6%. For a liquid, large-cap ETF with nearly $3.9bn in assets, a 41% short float is a genuinely unusual level of bearish conviction, reflecting sustained pessimism about Chinese equity exposure rather than a short-term tactical trade.

The borrow market tells a more nuanced story than the headline short interest figure. Availability has loosened sharply. With 51 million shares available for lending and availability running at 117%, there is now more supply in the lending pool than there are shares already borrowed, a reversal from the tighter conditions seen earlier in October, when availability dipped to around 55% on October 13. Borrowing costs reflect that easing: the cost to borrow fell nearly 20% over the week to 1.25%, well off the mid-October readings above 1.6%. The 52-week low on availability touched 0.26%, a reminder of how tight the borrow market can get on this name when macro sentiment turns hard against China. Right now, though, the lending pool is relatively comfortable. The ORTEX short score of 69.3 captures the overall picture: elevated, but having drifted down from 71.1 on October 13 as conditions loosened slightly.

Options positioning adds mild hedging pressure to the picture without screaming alarm. The put/call ratio is running at 1.02, just above its 20-day average of 1.00, with a z-score of 0.67. That places current demand for downside protection roughly in line with recent norms, far from the 52-week high of 1.23. Options traders are not piling into protection at an unusual rate, which provides some contrast with the elevated short interest level. The two signals together suggest the bearish positioning in FXI is concentrated in the direct shorting of shares rather than in the options market.

Institutional flows show a mixed picture among the largest holders. Morgan Stanley remained the biggest reported position at 14.7% of shares, last reported to June 30. Goldman Sachs added over 1.18 million shares in that same period, while Barclays added a larger 6.4 million shares, bringing its stake to 4.6%. D.E. Shaw and Nearwater Capital both entered as entirely new disclosed positions in the June quarter. On the selling side, Bank of America trimmed nearly 7.8 million shares and Citigroup cut 1.2 million. The net picture is one of banks and trading desks actively rotating around this ETF, consistent with its role as a liquid hedging and macro-expression vehicle rather than a long-only holding. BlackRock Portfolio Management separately filed a Schedule 13G in July disclosing a 6.1% passive stake of 8.7 million shares, though as a passive filing it carries no activist intent. Stakes in this register are as last disclosed; holders dropping below 5% may exit without a further filing.

Analyst data on this name is not usable: the latest coverage is dated October 2008, nearly 18 years stale.

The price has slipped 1.9% over the past week to $33.51 and 2.4% over the past month, modest moves given the macro backdrop. Past price events linked to this ETF show asymmetric tail risk: in April 2025 the fund fell 9.6% on a single day before partially recovering, while October 2025 brought a one-day decline of 0.8% followed by an 8.2% five-day fall. The directional outcome has varied, but the five-day windows after significant moves have been large in both directions.

With no scheduled earnings event and short interest still at more than four times the threshold that typically marks a highly shorted name, the key variable to watch is whether the recent loosening in availability holds or reverses, particularly if macro headlines around US-China trade or Beijing's policy stance shift the demand for borrow.
