Negative Balance Protection: When Your Account Cannot Go Below Zero

Normally a stop-out triggers before an account reaches zero. But sometimes price does not pass through levels — it jumps over them.

How a negative balance happens

The market opens Monday with a gap. Or a central bank changes policy without warning. Or a data release drains liquidity for a few seconds. The position closes not at the stop-out level but wherever the first matching volume appeared — sometimes hundreds of pips away.

The best-known case is the Swiss National Bank removing its franc cap in January 2015. EUR/CHF travelled thousands of pips in minutes. Thousands of retail accounts went negative and several brokers went bankrupt.

How the protection works

If the balance is negative after positions close, the broker zeroes it at its own expense. The client loses the whole deposit but owes nothing.

Under FCA, CySEC and ASIC this is mandatory for retail clients — a rule introduced after 2015. Check it against the entity you actually contract with: the Cyprus company will have it, the offshore one may not.

What it does not do

It does not reduce your loss and it does not insure your deposit. It only sets a ceiling: you cannot lose more than the account holds. The only way to never test it is to keep no more at the broker than you are prepared to lose entirely.
