Short Locate and Borrow AvailabilityHTB
Before a short sale, US brokers generally must have reasonable grounds to believe the shares can be borrowed — a “locate”. Borrow availability is how many shares lenders have available, and hard-to-borrow stocks have few, which makes borrowing expensive.
Before a US short sale, the broker generally needs reasonable grounds to believe the shares can be borrowed. This is called a locate. Borrow availability tells you how many shares lenders can supply, and hard-to-borrow stocks are scarce and expensive to short. Rules differ by country.

Locates in plain words
Before taking a short sale in any stock, a US broker must have reasonable grounds to believe the shares can be borrowed and delivered on time.1
That check — the “locate” — must be done and recorded before the short sale goes through.1
Hard-to-borrow shares are in high demand and may not be available, and they cost more to borrow.2
How a locate works
Choose a stock
Decide to short.
Broker checks supply
The broker looks for lendable shares.
Reasonable grounds
The broker confirms it reasonably expects to be able to borrow the shares for delivery.3
Document
That locate is recorded before the order is executed.1
Check the rate
Expect higher borrowing costs on hard-to-borrow names.2
Short
Only then is the short sale sent.
Worked examples
Example 1 — Easy to borrow
AllowedHypothetical: large-cap stock, plenty of shares.
| Locate | Instant |
Shares were available to borrow, so the short went ahead.3
Example 2 — Hard to borrow
≈ −328.77Hypothetical small cap, 1,000 shares at 10.00, borrow rate 40% a year, held 30 days.
| Fee | 10,000 × 0.40 × 30/365 ≈ 328.77 |
The stock was hard to borrow, and the higher fee ate into the return.2
Example 3 — No locate
BlockedNo lendable shares are available.
| Short | Rejected |
No locate, no short — the broker couldn't execute the order.1

| Aspect | Easy to borrow | Hard to borrow |
