| I don't think understand that correctly. There's no such thing as a SIPC-protected checking account that holds securities. A checking account holds cash. There's SIPC protection for your cash and securities (stocks etc.) that Robinhood holds for you, up to 250,000$ each. For obvious reasons, the value of a security in dollars fluctuates and therefore such losses cannot be insured. What is being recovered is the securities themselves, not their dollar value at a time of your choosing. > I don't know how that percentage of cash/securities breaks down at Robinhood, but it's not going to be 100% cash and 0% securities. There is a reason big banks don't offer checking accounts with 3% interest rates. When the return is higher, the risk must have gone up too, somehow. It's not the cash/securities that Robinhood holds as part of their business, it's the one they hold for you. You may well choose to hold 100% cash or 100% securities. Actual banks hold only a small fraction of cash deposits in reserve, many of their assets may just as well turn out to be made up of bad loans, bad junk bonds and bad stocks. That's how banks can fail even without a bank run. |
If I'm holding 100% securities, a) SIPC offers me no protection from losses, b) I better be making more than 3% return, and c) I would not call that situation "a checking account."
