Borrow Rate Monitor
Borrow rate time series, hard-to-borrow scanner and short squeeze candidates. Track the cost-to-borrow and identify stocks where elevated rates signal squeeze potential.
What is Borrow Rate Monitor?
Borrow Rate Monitor The Borrow Rate Monitor tracks stock lending costs over time, scans the market for hard-to-borrow names, and calculates squeeze scores combining borrow rate, IV, P/C ratio and vol compression.
Includes 1W and 4W velocity indicators showing whether borrow rates are accelerating or decelerating.
Why This Matters for Your Trading
How professional options traders use Borrow Rate Monitor to find edge.
Gauge Short Squeeze Potential
The squeeze score combines borrow rate, IV elevation, put/call ratio and vol compression into a single metric. High scores identify names where a short squeeze is mechanically more likely.
Price Your Short Options Correctly
High borrow costs affect put-call parity and synthetic pricing. If you're selling puts on a hard-to-borrow name, you need to know the borrow rate to price the trade correctly.
Track Rate Momentum
Velocity indicators show whether borrow rates are accelerating. A rate moving from 5% to 15% in a week signals increasing short demand — even if the absolute level isn't extreme yet.

Frequently Asked Questions
What is the squeeze score?
A composite metric combining borrow rate level, IV elevation, put/call ratio skew and vol compression. Higher scores indicate mechanically more favourable conditions for a short squeeze.
How are borrow rates classified?
Five tiers: Reasonable (0-3%), Moderate (3-10%), Elevated (10-25%), Hard to Borrow (25-50%) and Extreme (50%+). Colour-coded on the time series chart.
