Banco Santander heads into its July 22 second-quarter earnings release with the lending market tightening sharply — and options traders shifting notably more defensive in the final stretch.
The borrow-cost story is the clearest pre-earnings signal. Cost to borrow has climbed 56% over the past week to 1.85%, and is up 60% versus a month ago — the steepest rate seen in the 30-day window tracked here. Availability has tightened considerably too, dropping to 41.4% of shares short, versus readings above 70% that were common through late June and early July. That means roughly two shares remain available to borrow for every five already lent out — a noticeably tighter pool than the bank has seen for most of the past six weeks, though still above its 52-week floor of 33.4%. Short interest on the ADR has edged up about 1% in the most recent session to roughly 94 million shares, reversing a weekly decline of around 2%.
Options positioning has also turned more cautious than usual into the print. The put/call ratio has climbed to 0.52 — near its 52-week high of 0.53 — and running well above its 20-day average of 0.42, with a z-score of 1.37. That shift is stark: through June and into early July, the PCR was consistently in the 0.33–0.40 range. The rotation toward puts beginning around July 9 coincides with the borrow-cost acceleration, suggesting at least some overlap between hedgers and short-side participants.
The fundamental backdrop offers bulls meaningful ammunition. Santander's EPS surprise factor ranks in the 94th percentile of the ORTEX universe, and its forward earnings momentum sits at the 99th percentile — effectively top-of-universe. A recent market note flagged that Q2 results beat analyst expectations, with net interest margin holding up despite rate pressure and cost discipline offsetting provisions. The price-to-earnings multiple of 11.4x and price-to-book of 1.54x leave room for re-rating if the print confirms that trajectory. Bears, by contrast, can point to a stock that has dipped 2.3% over the past week to $13.55, suggesting some profit-taking after a positive month. Analyst data on record is too dated to be actionable — the most recent changes on file are from mid-2025 or earlier — so the Street debate can't be resolved from the coverage available here.
Institutional ownership is stable and tilted toward passive giants: BlackRock holds just over 7% of shares, with Vanguard entities and Dodge & Cox rounding out the top holders. None reported material position changes in the most recent filings. The earnings history shows the ADR gained about 1% on the day and roughly 2.7% over five days after the most recent prior print — a muted but constructive pattern.
The July 22 release is therefore less about the direction of Santander's profits and more about whether the bank can sustain its margin resilience and capital returns at a pace that justifies the premium the stock has built over the past year — and whether the abrupt tightening in borrow conditions in the final days before the report reflects genuine conviction on the short side or simply pre-earnings hedging activity unwinding after the bell.
