What is Hard to borrow?
A hard-to-borrow stock is one whose broker struggles to locate shares of, usually because few holders are willing to lend it out or too many traders want to short it at once. It carries a higher borrow fee than an easy-to-borrow stock, and a higher chance the shares get recalled mid-trade.
Most large, widely held stocks are easy to borrow — plenty of shares sit in margin accounts, and a broker can locate them for a new short seller without much trouble. A stock becomes hard to borrow when that supply runs thin: it might be a small-cap with few lendable shares to begin with, or a large-cap that's suddenly attracted so many short sellers that available supply can't keep up with demand. Either way, the broker has to work harder — and sometimes fails outright — to find shares for you to borrow.
Two things follow directly. The borrow fee runs much higher, since it's priced on scarcity like any other rental market. And because fewer lenders are holding the stock, a recall is more likely to become a real problem: if the lender you're borrowing from sells, your broker has fewer alternative lenders to turn to, which raises the odds of a forced buy-in rather than a quiet substitution.
For example
A widely shorted small-cap might cost 30% a year to borrow, against roughly 0.3% a year for a large, liquid stock — a hundred times the rent for holding the same $8,000 short position.

Hard-to-borrow status is both a cost and a signal. It tells you the trade will be more expensive to hold and more likely to be interrupted by a recall, and it often means a lot of other traders have crowded into the same short — which is exactly the setup that makes a short squeeze more likely.
⚠ A cheap-looking short can turn expensive overnight
A stock can be easy to borrow when you open the short and turn hard to borrow later, if more traders pile into the same idea. Since the fee is repriced by the broker rather than locked in at entry, a position you opened cheaply can start costing real money to hold — often right as your thesis is playing out and everyone else notices too.
