Key:

General Collateral stocks are highly liquid securities readily available to borrow and lend in the Securities Lending market. Note: General Collateral stock may become Hard-to-Borrow due to changing market conditions.

Hard-to-Borrows are securities that may not be readily available to transact in the Securities Lending market due to factors such as low liquidity, elevated demand for borrow, heightened volatility or regulatory restrictions.


Borrow Fee Rebates for Short Sale Proceeds3

Accounts with NAV of JPY 15MM (or equivalent) or more will be issued a rebate on their stock borrow costs. Accounts with NAV of less than JPY 15MM (or equivalent) will be issued rebates at rates proportional to the size of the account. There will be no rebates issued on the first JPY 15MM.

Disclosures

  1. Any trading symbols displayed are for illustrative purposes only and are not intended to portray recommendations. This information is of a general nature. It does not take your specific needs or circumstances into consideration, so you should look at your own financial position, objectives, and requirements and, if required, seek professional financial advice before making any financial decisions.

    Past performance is not a reliable guide to future performance, the performance of investments is not guaranteed, and the value of your investments can go down as well as up, so you may get back less than you invest.

  2. Cost to borrow calculations assume NAV is greater than or equal to JPY 15MM. Accounts with NAV below JPY 15MM may receive borrow fee rebates for short sale proceeds at rates which are proportionally less.
  3. For balances held in JPY or RUB, IBKR may apply an effective negative rate to long balances held. The negative rate applied to accounts holding these currencies is the same regardless of account size. For currencies in which the effective rate is less than zero, the borrow fee rebate is 0%.
