What Is Freeriding and Why Does It Freeze a Cash Account?
Freeriding is buying shares in a cash account and covering the bill with the money from selling them. Regulation T treats it as trading on credit the account does not have.
Definition
Freeriding: Buying securities in a cash account and paying for them with the proceeds of selling those same securities, without ever having paid for the purchase itself.
Also called Free-riding violation.
Put simply, a freerider buys in a cash account, never pays for the purchase, and settles the bill by selling the very shares that were never paid for.
Put that way it sounds like an accounting technicality. In practice it is borrowing. For the time between the buy and the sale, the broker’s money is carrying your position, and a cash account is by definition an account where the broker does not lend.
Regulation T is the Federal Reserve rule that governs credit in brokerage accounts, and it requires purchases in a cash account to be paid for in full, which is exactly the promise a freerider breaks by letting the sale settle the bill. When a customer sells before paying, the account generally faces a 90-day restriction. For those 90 days, every purchase must be fully paid upfront. The settled funds have to be in the account before the order goes in.
A worked timeline
The sequence is short, and a trader can walk into it within a single session if they do not know what their account is actually holding.
The profit changes nothing. A loss would not help. The account would then owe the difference as well.
Money would have prevented it. Had the 3,800 shortfall been deposited, and cleared, before the afternoon sale, the purchase would have been paid for with your own funds and the sale would have been an ordinary round trip in a cash account.
Some platforms block the first buy outright when settled cash cannot cover it. Others accept the order and flag the account afterward. Which one yours does depends on its settings and on how it presents buying power in a cash account, so the order screen accepting your trade is no evidence that the trade was allowed.
Freeriding and good faith violations compared
Both involve selling before something settles, so the two get mixed up. The question that separates them is what paid for the purchase.
| Good faith violation | Freeriding | |
|---|---|---|
| What paid for the buy | Proceeds of an earlier sale, still unsettled | Nothing; the buy was never funded |
| What you then sell | The new position, before the earlier proceeds settle | The same shares, which then pay for themselves |
| Usual consequence | Warning, then a settled-cash restriction after repeats, set by broker policy | A 90-day restriction under Regulation T, generally from the first instance |
A good faith violation involves money that exists and is on its way. Freeriding involves money that never existed in the account. Hence the harsher treatment. A single instance can be enough.
Both rest on the settlement date. Under T+1 the gap is a single business day for most US stocks, though a weekend or a market holiday stretches it.
What the freeze does and does not stop
You can still trade during the restriction. Selling works as usual, and so does buying, as long as the cash to pay for every purchase has settled and is sitting in the account before you place the order.
What you lose is any use of unsettled money. Sell on Monday and the proceeds cannot fund a new purchase until they settle. For an active account, every sale becomes a pause. Whether a broker will ever shorten the freeze is its own procedure. Do not assume it will.
Keeping clear of it
Know the settled cash figure before you place a buy. Most platforms list it alongside a larger number, often labeled something like cash available to trade, and in a cash account the settled figure is the one that limits what you can pay for.
Deposits are the other half. A transfer still marked pending may already count toward the buying power shown on screen, and brokers differ on whether shares bought against it can be sold straight away. Until it clears, treat that deposit as money you do not have yet.
Frequent same-day round trips and a cash account sit badly together. The limits are covered in can you day trade in a cash account.
