Insider Trading in Forex: Is It Illegal, and How Does It Work?

Picture a quiet afternoon on EUR/USD, twenty minutes before a central bank rate call. The pair is barely moving. Then, with nothing on the wire yet, it lurches forty pips in one direction.

The print drops moments later, confirming the move. You sit back and think the thought almost every trader has had at some point: someone knew.

That feeling sits behind nearly every search for insider trading in forex. It is the suspicion that the market is not a level field, that the big players see what you cannot, and that maybe what they are doing crosses a line.

Fair questions, all of them. Honest answers are more interesting than a flat yes-or-no, and they change how you think about your own trading.

Key takeaways

• South African insider-trading law does not treat all forex products equally.
• Section 78 of the Financial Markets Act focuses on securities listed on a regulated market. These securities can include listed derivative instruments.
• An ordinary spot USD/ZAR trade is not usually a listed security. A JSE-listed currency future or option may fall within the Act.
• Section 78 covers more than trading for personal profit. It also covers trading for another person, dealing for an insider, unlawful disclosure, and encouraging or discouraging someone from trading.
• Public SARB statements, economic calendars, charts, analyst reports, and Stats SA releases are lawful research sources. An unreleased rate decision, private economic report, or confidential client order is different.

What we actually mean by insider trading

The term did not start with currencies. It grew up in the stock market, and that origin matters more than people realise.

Insider trading, in its classic form, means buying or selling a company’s shares based on material information that the public does not yet have.

A finance director sees the quarterly numbers before they are announced. She knows earnings have collapsed, so she sells her shares the day before the news goes out, dodging the drop.

Or a board member hears a takeover is coming, buys ahead of the announcement, and pockets the jump. 

Notice the three ingredients that have to be present.

• There is a company, an issuer of shares, around which the trade is built.
• An insider exists, someone who holds a position of trust and owes a duty to that company and its shareholders.
• There is material non-public information, a fact big enough to move the price, that has not been released yet. Take any one of those away, and the classic case starts to wobble.

Hold those three pieces in mind, because forex breaks at least one of them straight away.

Why is insider trading illegal?

Strip away the legal jargon, and insider trading comes down to one thing: fairness. Markets work because everyone plays by the same rules, reads the same public information, and takes the same risks.

An insider tears that up. They trade on knowledge nobody else can reach. And they profit at the direct expense of the person on the other side, someone who never had a chance.

That’s why it sits so badly. It isn’t clever. It’s a quiet form of theft, dressed up as a smart trade. Someone in a position of trust takes information they were meant to protect and turns it to their own private gain.

There’s a higher cost, too. When people sense the game is rigged, they stop trusting the market itself. And a market without trust slowly stops working for everyone in it, including you.

So the law isn’t punishing success or sharp analysis. It’s the level field that protects honest trading in the first place. Fairness, in the end, is the whole point.

Insider trading vs market manipulation

Forex traders toss these two around like they’re the same thing. They’re not, and the difference gets clear once you see it.

Insider trading is about information: you trade on information that others can’t access.

Market manipulation is about action; you actively distort the price to mislead everyone else. One exploits what you know. The other engineers what people see.

Below is a table comparison:

Aspect	Insider trading	Market manipulation
Core act	Trading on secret, price-moving information	Actively distorting price or volume
Approach	Passive — you exploit what you know	Active — you create false signals
Effect on price	Nudges it toward true value, just early	Pushes it away from the true value
Who’s misled	The trader on the other side of your deal	The whole market is reading fake supply and demand
Forex example	Acting on a leaked central bank decision	Spoofing orders or rigging the daily fix
Status in South Africa	Prohibited under the Financial Markets Act	Prohibited under the Financial Markets Act

Does Insider Trading Apply to Forex?

Yes, but not in the same way it applies to company shares.

Classic insider trading laws usually focus on securities. For example, a company director may know about an unreleased takeover and buy shares before the announcement.

Spot currencies are not company shares so that the legal treatment may differ depending on the financial instrument being traded and the applicable laws in the relevant jurisdiction.

That does not make private forex information safe to trade.

In forex, the key question is often not, “Is this technically insider trading?” Instead, ask, “Was confidential, market-moving information misused?”

Imagine a central bank employee learns that interest rates will rise unexpectedly. The employee tells a friend, who buys the currency before the decision becomes public. That trade could breach market-abuse, fraud, confidentiality, corruption, or financial conduct laws.

The same concern applies to leaked inflation figures, employment data, currency intervention plans, and government policy changes.

Client order information also matters. Suppose a bank dealer knows that a large fund plans to buy billions in USD/JPY. If the dealer buys first, expecting the client’s order to push prices higher, that is commonly called front-running. It may be treated as fraud, market abuse, or breach of duty.

Your forex product also affects the legal position.

Different products, including spot forex, currency futures, options, swaps, CFDs and exchange-traded funds, may be subject to different legal and regulatory frameworks depending on the jurisdiction.

As a retail trader, you can trade before economic news using public forecasts, price action, bond yields, and your own research. Correctly predicting a rate decision is not insider trading.

The warning sign is receiving the actual result from someone with private access.

If a bank worker, government employee, broker, or “signal provider” claims to have confidential data, do not trade on it. Do not forward it or pay for more.

The practical rule is simple: lawful trading decisions should be based on publicly available information, independent research, and your own analysis. An unlawful edge may arise from leaked data, private client orders, bribery, deception, or a breach of the duty of trust.

Famous insider trading cases

Insider trading is just trading on price-sensitive information before it’s public, an unfair edge over everyone else staring at the same screen. Some of these are textbook insider trading cases, while others involve related forms of market misconduct, such as collusion or market manipulation.

FX cases

• The 2013–15 forex-fixing scandal: This one’s collusion rather than classic insider trading, but it’s the big FX black eye. Senior dealers at banks like Citi, JPMorgan, Barclays, RBS, and UBS sat in private chatrooms, one literally called “The Cartel“, coordinating to nudge the daily WM/Reuters benchmark fix in their favour and front-run client orders.

Regulators across the US, the UK, and beyond imposed more than $10 billion in combined fines, and several banks pleaded guilty to criminal charges in 2015. The lesson: even at the very top of the FX food chain, the chat logs hang you.

• Hill–Kamay (Australia): Cleanest “insider trading on FX” case out there. Christopher Hill, an employee at the Australian Bureau of Statistics, leaked unpublished economic data- labour force, retail trade, building approvals to his university mate Lukas Kamay, a National Australia Bank trader, who’d buy foreign exchange derivative contracts in the minutes before the 11:30 am data release and sell shortly after.

Kamay banked an estimated A$7 million while Hill received only about A$20,000. A broker noticed Kamay’s suspiciously well-timed bets, found the ABS connection on LinkedIn, and tipped off the police; Kamay got seven years and three months, the longest insider trading sentence in Australian history at the time, and Hill got three years and three months.

The equities classics

• Ivan Boesky (1980s): The arbitrageur who inspired Gordon Gekko’s “greed is good.” He paid corporate insiders for tips on upcoming mergers, then traded ahead of the announcements.
  

In 1986, he pleaded guilty, paid a $100 million penalty, served roughly three and a half years, copped a lifetime securities ban, and his cooperation helped bring down Michael Milken and Drexel.

• Martha Stewart / ImClone (2001): Good one, because of the nuance you flagged. She dumped her ImClone shares on a tip that the FDA was about to reject the company’s cancer drug, dodging a loss.
  

But she was convicted in 2004 for obstruction, conspiracy, and lying to investigators, not insider trading itself, and served five months. ImClone CEO Sam Waksal, who actually tipped, pleaded guilty to insider trading and got about 7 years.

• Galleon / Raj Rajaratnam: The hedge fund case that changed enforcement. Rajaratnam ran billions through Galleon on a network of insiders feeding him tips, including Rajat Gupta, a Goldman board member and former McKinsey head who leaked boardroom moves.
  

The FBI used wiretaps for the first time in a major insider case, and in 2011, Rajaratnam got 11 years, the longest insider trading sentence handed down.

• SAC / Steve Cohen. His firm, SAC Capital, pleaded guilty in 2013 and paid $1.8 billion after portfolio manager Mathew Martoma was convicted for trades based on a leaked Alzheimer’s drug trial, one of the most profitable insider schemes ever.
  

Cohen himself was never criminally charged; he settled civil claims, sat out a couple of years, and came back with Point72.

South Africa

• Steinhoff/Markus Jooste. Our biggest corporate scandal, full stop. Steinhoff was a JSE Top 40 retail giant until December 2017, when fake transactions worth $6.5 billion (per the PwC audit) inflated profits, unravelled and close to 98% of the share value was wiped out, leaving investors, including the PIC pension fund, with losses running into hundreds of billions of rand. 

On the insider trading specifically: days before the collapse, Jooste SMSed associates, warning them to sell their Steinhoff shares immediately and delete the message- classic tipping- even though he made no money from the insider trading himself; but as the tipper, he was liable. 

The FSCA fined him R122 million for that, later reduced to R20 million on appeal, then hit him with a separate R475 million penalty for the false and misleading statements; he died by suicide in March 2024, a day after that penalty and an arrest warrant landed.

Common thread across all of them: the edge feels worth it right up until surveillance, chat logs, or one badly timed trade gives you up. Regulators like the FSCA look backwards at price movements around every announcement, and they’ve got the tools to do it properly now. Never worth your freedom or your licence.

How insider trading is policed and why active traders stay on the right side

Insider trading makes for dramatic headlines, but most active traders never go near it. If you’re working off a chart, an economic calendar and a live price feed, you’re trading on information everyone else can see too.

Who’s watching, by region

FSCA and the Directorate of Market Abuse (South Africa): The FSCA is our market conduct regulator, and its Directorate of Market Abuse handles insider trading, market manipulation, and false statements under the Financial Markets Act.

The JSE conducts electronic surveillance of listed securities and refers any suspicious activity to the FSCA for investigation.

The FSCA can order an offender to hand back the profit and pay up to three times that amount on top. It refers criminal matters to the National Prosecuting Authority, where the ceiling is R50 million or ten years.

SEC and DOJ (United States): The SEC regulates US securities markets and brings civil cases; the DOJ handles criminal cases. Their reach runs deep.

The Galleon prosecution in 2011 was the first major insider-trading case built on wiretaps, and it ended in an eleven-year sentence.

FCA (United Kingdom): The FCA enforces the UK Market Abuse Regulation. Trading venues and the firms that arrange or execute trades have to report suspicious transactions and orders to the FCA without delay, and company managers must disclose their own dealings.

ESMA and MAR (European Union): The EU’s Market Abuse Regulation covers insider dealing, unlawful disclosure of inside information, and manipulation across all member states.

After the LIBOR scandal, it was extended to include benchmark rigging, directly in the same category of conduct as the forex-fixing scandal. ESMA coordinates; the national regulators enforce.

CFTC (US FX derivatives). Trading FX futures or options puts you under the CFTC. It runs its own market surveillance and whistleblower programme for commodity and derivatives fraud.

How do they actually catch it?

Three things do most of the work.

• Trade surveillance – Exchanges, venues, and brokers run automated systems that flag odd patterns, a perfectly timed bet right before an announcement, unusual volume, and trades that don’t fit a trader’s history. After any major news, regulators look back at who traded, when, and why.
• Disclosure regimes – Listed companies have to publish price-sensitive information promptly, keep lists of who’s seen it, and report when insiders trade. The faster information goes public, the smaller the window anyone has to misuse it.
• Whistleblowing – The SEC and CFTC pay whistleblowers between 10% and 30% of sanctions above $1 million, and MAR-regulated firms must run internal reporting channels. In both the forex-fixing and Galleon cases, it was insiders, chat logs, and tip-offs that cracked them open.

Conclusion

Insider trading can apply to forex in South Africa, but the instrument being traded matters.

Section 78 of the Financial Markets Act addresses inside information relating to securities listed on a regulated market. A direct spot USD/ZAR position may not always fall within that definition, although other legal and regulatory obligations may still apply depending on the circumstances.

A listed currency future, option, or related security may fit it. That difference should never be mistaken for permission to trade on leaked information.

An unreleased SARB decision, a private Stats SA figure, a confidential client order, or a secret corporate announcement should raise an immediate warning. 

Active traders are allowed to form strong views before major news. You can study inflation, bond yields, central bank speeches, positioning, charts, and public forecasts. You can also trade against the market’s main view.

The problem starts when your edge comes from information that other traders cannot lawfully access.

When confidential information reaches you, do not trade on it, share it, or ask for more.
