The IB Custodial Account Protection Program provides insurance coverage of up to $30 million per account, which includes up to $1.5 million in cash balances. This coverage is in addition to the protection provided by SIPC insurance.
It's important to note that the IB Custodial Account Protection Program is not SIPC insurance, but rather an additional insurance policy purchased by IB.
