Borrow-Fee Tiers
Tapeboard categorizes annualized borrow fees as normal (under 2%), elevated (2-10%), hard-to-borrow (10-50%), and extreme (above 50%). On August 19, 2026, 18 names on today's market-wide list fell in the hard-to-borrow or extreme tier. That concentration at the top is notable: seven names carry triple-digit fees, each indicating severe scarcity in the securities-lending pool. The remaining 11 names in the 10-50% band are more typical of what traders see when shares are tight but still locatable with effort.
What a High Borrow Fee Signals
An annualized borrow fee is the stock-loan cost a short seller pays; a high fee reflects scarcity in the lendable pool; it does NOT by itself predict a squeeze. Names with triple-digit fees are often distressed, very-low-float, post-reverse-split, or recently IPO'd stocks where shares are almost impossible to locate — high cost-to-short is not the same as squeeze potential. While a rising borrow fee can indicate that short interest is building or that lenders are demanding more compensation for risk, the fee alone does not tell you whether a stock is poised to move higher. Borrow fee is weighted 25% in Tapeboard's composite squeeze score, which also incorporates the methodology factors like price momentum, volume trends, and short interest positioning to separate true squeeze setups from merely expensive-to-borrow names.
