Leveraged trading can lead to losses exceeding the deposited funds. This is a mathematical fact, not an exception. The subsequent question is: who bears the loss beyond zero? Does the trader have to transfer additional funds to the broker, or does the broker absorb that portion themselves?
Negative Balance Protection is the mechanism that answers this question. This article explains what Negative Balance Protection is, how an account can go negative despite a Stop Out system, which regulatory bodies enforce it, and the extent of this protection, without naming specific brokers.
Negative Balance Protection is a rule or policy that limits a trader's liability to no more than the funds in their trading account. If the market moves violently, causing the account balance to fall below zero, the broker will adjust the balance back to zero and absorb the excess loss themselves. Traders can lose a maximum amount equal to the funds in that account.
The Stop Out system is designed to close positions before the account runs out of funds. The mechanics of Margin Level and Stop Out points are explained in What is a Margin Call? When is it triggered? How to prevent it? The often-overlooked point is that a Stop Out is a "trigger to close," not a "guaranteed price."
When the Margin Level reaches the Stop Out level, the system sends an order to close positions at the next available market price. In normal markets, the next price is only a few pips away, but there are two situations where the next price might be significantly further.
Let's look at a hypothetical example (figures for illustration, not actual data). A trader has $1,000 and holds a Buy EUR/USD 1 lot with high leverage. One pip is worth $10. Assume the system would Stop Out when the price moves against them by about 90 pips, leaving approximately $100 in the account. However, the market opens the new week 200 pips lower than Friday's closing price. The closing order is therefore filled at the first available price, resulting in a $2,000 loss, and the account balance becomes −$1,000.
Such price gaps can occur due to unexpected policy changes by central banks. A frequently cited example is January 15, 2015, when the Swiss National Bank (SNB) announced the discontinuation of its minimum exchange rate policy for the Swiss franc (SNB, 2015). The higher the leverage used, the narrower the distance between the Stop Out point and zero (What is Forex Leverage? How risky is it?)
The answer depends on whether the account is covered by Negative Balance Protection.
If covered, the −$1,000 balance in the example would be adjusted back to zero. The trader loses all $1,000 deposited but incurs no outstanding debt.
If not covered, that negative balance is a debt according to the client agreement. The broker has the right to collect it. Some may choose to waive the debt, but that is at their discretion, not a right of the trader.
Figures from Australia's ASIC show that this issue occurs widely. During a volatile 5-week period from March to April 2020, a sample of 13 CFD issuers found that over 15,000 retail client accounts had negative balances, totaling $10.9 million in debt. This compares to 41,000 accounts with a combined negative balance of $33 million throughout 2018. ASIC stated that "some debts were waived," which implies that the remaining portion was not (ASIC 20-254MR).
Negative Balance Protection for retail clients became mandatory in several jurisdictions after 2018, accompanied by leverage caps and rules to close positions when the account balance falls to 50% of the required margin (ESMA, 2018, FCA, 2019)
| Authority | Effective Date | Who is Protected | Scope per Document |
|---|---|---|---|
| ESMA (European Union) | August 1, 2018, as a temporary measure, expired July 31, 2019, then national authorities introduced permanent measures instead (ESMA opinion) | Retail clients | Account-by-account protection. Clients cannot lose more than the funds used to trade CFDs in that account (ESMA Q&A) |
| CySEC (Cyprus) | Permanent national measures after ESMA's expired (ESMA issued opinion on September 27, 2019) | Retail clients | Similar to ESMA's measures, with some exceptions (ESMA opinion) |
| FCA (United Kingdom) | August 1, 2019 (permanent rule) | Retail clients | Liability limited to funds in the account, according to COBS 22.5.17R (FCA Handbook) |
| ASIC (Australia) | March 29, 2021, extended until May 23, 2027 | Retail clients | Limits CFD losses to the funds in the CFD trading account (ASIC 22-082MR) |
The term "funds in the account" has a clear definition. Both ESMA and FCA use the same meaning: cash in the trading account plus the net unrealized profit/loss of open positions. Funds or other assets not used for trading these products are not included (FCA COBS 22.5.19G, ESMA Q&A Section 5.4).
Measured results after implementation: ASIC reported that in the first six months of the order, the number of times retail client accounts went negative decreased by an average of 88% per quarter (ASIC 22-082MR). The FCA estimated when issuing the rules that this measure would save retail consumers approximately £6 million per year (FCA PS19/18). The overall level of protection still varies among different authorities. Details can be found in How do FCA, ASIC, CySEC, FSCA differ? Which one truly protects?
The name sounds like a catch-all, but its actual scope is narrower.
During the consultation period before issuing the rules, the FCA also noted concerns from respondents, such as the cost of protection potentially widening spreads, and the risk of traders opening offsetting positions across multiple accounts before significant events. The FCA responded that firms can detect such strategies with existing surveillance systems (FCA PS19/18).
The statement "Negative Balance Protection available" on a website is not enough. What you should check is:
Documents can only state the policy; they do not guarantee that the company will adhere to it every time. However, they clarify where the trader's rights are written.
Important Note: Forex trading is not yet licensed or regulated by any authority in Thailand. The Bank of Thailand does not have a policy to issue licenses for Forex businesses to retail individuals (Reference: Thai PBS), and the SEC itself confirms that the Forex business is not under the supervision of the SEC but rather under the currency exchange control law (Reference: The Standard).

How do Negative Balance Protection and Stop Loss differ?
A Stop Loss is an order set by the trader to close a position at a specific price, and it may be filled at a worse price during a price gap. Negative Balance Protection, on the other hand, functions after that, limiting the total account balance from falling below zero. Both operate on different levels.
Do Professional accounts receive Negative Balance Protection?
According to ESMA, FCA, and ASIC rules, they do not automatically receive it, as these rules apply to retail clients. Some companies may offer it as an additional policy, which must be checked on a case-by-case basis in the agreement.
Can brokers not under these regulations offer Negative Balance Protection?
Yes, in the form of a voluntary policy. The difference is that traders do not have a regulatory body to enforce that rule. All rights therefore depend on the wording in the client agreement.
Is this protection available for Forex trading in Thailand?
There are no Thai laws that stipulate this for Forex trading, as this business is not licensed in Thailand, as noted above. Any protection traders receive therefore comes from the laws of the country where the broker is registered or from the company's policy.
