What is Wash Trading: Day Trading and Wash Sales, A Closer Look

Summary

• Wash trading represents a form of day trading with significant ramifications for the traders or entities involved in such activities.
• Wash trading typically takes place with the intention to influence buy and sell decisions, ultimately benefiting the trader or entity executing the trade.
• Wash trading is actively prohibited under both the Commodity Exchange Act and the Securities Exchange Act, making it a serious regulatory violation.

Numerous trading schemes exist that operate at the very edge of legal activity, with some crossing directly into illegal territory. Whether such actions stem from poor advice, greed, or simply hasty and rash decision-making, they can irreparably damage the reputation of an individual or financial firm. Wash trading is precisely such an activity—a form of day trading that carries enormous consequences for those involved. Understanding what exactly constitutes a wash trade and why it is so poorly received in the financial industry serves as the best defense against committing such fraud.

This comprehensive article examines the legal implications of wash trading, wash sales, and their effects on both the day trading and cryptocurrency industries. Additionally, we provide a detailed historical perspective to clarify how such practices became so deeply embedded in the world of finance and continue to pose challenges for regulators and honest traders alike.

What Is Wash Trading? Wash Trading Explained

Wash trading occurs when securities transactions, or multiple transactions, are structured to appear as authentic purchases and sales—but upon closer examination, prove to be fictitious or manipulative in nature. This typically happens when an investor simultaneously buys and sells the same security or investment at virtually the same time. The result is that a trader creates the false appearance of legitimate trading activity without actually changing their portfolio position. Wash trading is also frequently referred to as round-trip trading within financial industry terminology, which can sometimes lead to confusion among those less familiar with trading practices.

In certain cases, wash trading represents a deliberate and intentional attempt at market manipulation, designed to deceive other market participants. In other instances, it may result from honest mistakes or simple ignorance on the part of traders attempting these transactions. While wash trades most commonly refer to the misreporting of stock or security trade activity, they can also occur extensively in the cryptocurrency industry, as we will explore in greater detail later in this article. Regardless of which area of finance you choose to trade in—whether centralized (CeFi) or decentralized (DeFi)—it is essential to understand the potential implications and serious consequences of being involved in a wash trade.

In cases of deliberate wash trading, such actions usually take place specifically to influence buy and sell decisions in ways that benefit the trader or entity making the trade. Whether the goal is to create the false appearance of increased price activity, spuriously influence trend line indicators used by analysts to evaluate market conditions, or manipulate volume metrics, wash trading is highly frowned upon by regulators, exchanges, and legitimate market participants. This naturally raises an important question: is wash trading actually illegal?

Is Wash Trading Illegal? Wash Trading Security Explained

In a nutshell, yes—wash trading is illegal.

Wash trading is actively prohibited under both the Commodity Exchange Act and the Securities Exchange Act of 1934, which established clear regulatory frameworks to prevent market manipulation. However, enforcement can sometimes prove challenging, as sanctioning bodies must be able to demonstrate clear intent and actual harm. In fact, to legally establish that a wash trade has occurred, regulators must prove two distinct forms of precedent:

• Intent: To legally establish that wash trading has been conducted in any form, the parties involved (typically a broker and an investor, or multiple related entities) must be proven to have entered into the trade deliberately and with full knowledge of its manipulative nature. In such cases, adjudicators can reasonably assert that a wash trading violation was committed intentionally to benefit one or all of the parties involved. Should this be found true through investigation and evidence gathering, regulators will take necessary enforcement steps to reprimand those offending parties, which may include fines, trading bans, or criminal prosecution.

• Result: As one might expect, the transaction under regulatory scrutiny must have demonstrably resulted in a wash trade according to legal definitions. By this standard, the investors or entities that both bought and sold the asset or security must be shown to have done so at the exact same time, or within a suspiciously short timespan that indicates coordination. Regulators must also prove these parties are associated with the accounts that executed the trade, or at minimum have some form of beneficial ownership of the asset or security in question.

Beneficial ownership refers to any separate account that is ultimately owned or controlled by the same individual or entity at the time of making a trade. This explains why trades executed between two accounts with the same ultimate benefactor often draw immediate attention from regulatory authorities, as such patterns usually signify that some form of illegal activity or market manipulation may be taking place. Understanding these legal frameworks helps traders avoid inadvertently crossing regulatory lines.

What Is A Wash Sale In Day Trading? Day Trading and Wash Sales Explained

To better understand what constitutes a wash sale, the most effective approach is to examine the precise legal definition and its practical applications. Wash sales are transactions or exchanges in which an investor sells a losing security (that is, an asset on which they are likely to realize a financial loss) specifically in order to claim a capital loss for tax purposes. A capital loss, as the term suggests, occurs when an asset or security decreases in value; however, that value decrease is not actually realized for tax purposes until transactions are finalized and settled. This creates an opportunity for manipulation that regulations seek to prevent.

This means that a trader attempting to violate wash sale laws can employ several strategies:

• Buy substantially identical or similar assets and securities back again within a short timeframe.
• Acquire substantially identical or similar assets and securities through a fully taxable trade or exchange.
• Acquire an option or contract to buy substantially similar securities in the near future.

If the trader executes any of these actions within 30 days before or after having made the original sale at a loss, this is legally defined as an illegal wash sale under IRS regulations. In some cases, this violation results from pure ignorance or an innocent misstep on the part of the investor making the trade, particularly among less experienced traders. However, more commonly it represents a deliberate attempt to realize a tax deduction while simultaneously maintaining market exposure to the asset or security being traded. In the following section, we will examine the Wash Sale Rule in greater detail to better understand what legally constitutes a wash sale in day trading activities.

What is the Wash Sale Rule in Day Trading?

The wash sale rule is a specific regulation issued by the Internal Revenue Service (IRS) that prevents taxpayers from claiming a tax deduction for securities sold during what qualifies as a wash sale. This rule comprehensively covers all the aforementioned scenarios—whether the security is repurchased directly, an option to repurchase is acquired, or the security or asset is simply re-acquired through a taxable trade or exchange, the regulatory result remains the same.

Furthermore, a sale will be legally considered a "wash sale" if an individual sells a security at a loss, and then either the individual's spouse or a company controlled by the individual or spouse buys its substantial equivalent within that same 30-day window period before or after the sale. This extended definition prevents traders from attempting to circumvent the rule through family members or controlled entities, closing common loopholes that might otherwise be exploited.

Are Wash Sales Illegal? Wash Sales Security Explained

Now that we have thoroughly examined what constitutes a wash sale and the wash sale rule in day trading, the question naturally turns to matters of legality and enforcement. While wash sales themselves are not precisely illegal as transactions, claiming them as capital losses in order to earn a tax break or deduction is illegal and fully prosecutable under federal law. This legal precedent has been firmly established in order to disincentivize companies and individual investors from selling assets or securities at a loss purely for the purpose of obtaining tax deductions, while maintaining their actual market positions.

This means that as long as a trader does not repurchase a substantially similar asset to the one they sold at a loss within the 30-day window period, or better still does not attempt to write this transaction off as a tax-deductible loss at all, they cannot be prosecuted for committing an illegal wash sale. However, traders must exercise caution and maintain detailed records of all transactions to demonstrate compliance.

Some practical difficulties can arise from the legal definition and its application, however. This is primarily because the IRS has not provided an exhaustive or precise definition of what they mean by "substantially similar" or "substantially identical" in strict legal terms. As a result, traders attempting to avoid violating wash sale rules must carefully review various third-party provided guidelines and seek professional tax advice when necessary. One of the more helpful analytical frameworks is the facts and circumstances test. In this test, it is clearly stated that any investor should carefully consider all available facts and circumstances in their specific case before making trading decisions. According to IRS guidelines, assets or securities from one corporation are generally not considered "substantially similar" to those of another distinct corporation, nor are bonds considered substantially similar to stocks, preferred stocks to common stocks, or anything of that nature.

Is There Such A Thing As Crypto Wash Trading?

Unscrupulous brokerages and trading platforms engage in wash trading with cryptocurrency with alarming and increasing frequency. The digital currency industry remains, as things currently stand, significantly under-regulated compared to traditional financial markets—a situation that has unfortunately allowed the less palatable and manipulative aspects of trading to flourish unchecked in its midst. In fact, according to various statistical analyses and research reports, the problem of wash trading with crypto pairs and digital assets is as prevalent—if not substantially more so—than it has ever been in the certified and regulated financial industry. This situation persists largely because the tax laws that govern cryptocurrency transactions follow the same guidelines as property tax laws in most jurisdictions, rather than the more stringent regulations applied to stocks and securities.

Wash trading in cryptocurrency can take many different forms and manifestations, and is not merely relegated to the direct trade of cryptocurrency pairs on exchanges. The practice extends to various digital asset classes and trading mechanisms. Let us examine the increasingly common practice of NFT wash trading in order to gain a better understanding of how prevalent this manipulative practice has become in the digital currency ecosystem, and to appreciate the true scale of its proliferation across different market segments:

What is NFT Wash Trading?

According to multiple authoritative sources and blockchain analysis firms, many industry experts believe that the estimated $44 billion in reported non-fungible token (NFT) sales in recent years may have been, at least partially, artificially inflated by wash trading activities. While it remains extremely difficult to quantify this with absolute certainty due to the pseudonymous nature of blockchain transactions, some examples of suspicious activity are actually hiding in plain view, according to a comprehensive report published by Chainalysis in recent reports. The company, which specializes in monitoring blockchain-based activity and detecting suspicious patterns, has identified some deeply worrying discrepancies and anomalies emerging across major NFT marketplaces.

In this detailed report, Chainalysis investigators found numerous cases where single NFTs had been sold repeatedly to digital wallets that were ultimately owned by the same individual who was selling the NFT in question—in some instances more than 25 consecutive times in rapid succession. The company's blockchain analysts assert that these transaction patterns represent classic and textbook examples of wash trading, designed to artificially inflate trading volumes and create false impressions of demand. In examining just 110 profitable cases of suspected wash trading that they studied in detail, the analysts calculated that the illicit profits totaled nearly $9 million, suggesting the true scale of the problem may be substantially larger across the entire NFT ecosystem.

What Is the History of Wash Trade? Wash Trading Background Explained

Prior to becoming officially banned through federal legislation in 1936, wash trading was a commonplace and widely practiced activity amongst traders in both commodity and securities markets. Used deliberately to falsely signal interest and activity levels to other rival investors and market participants, wash trades were—and in some ways still are—a popular method employed by market manipulators attempting to artificially pump up the perceived value and trading volume of a stock or commodity. After the period of extremely competitive and volatile trading that followed the Great Depression and the market crash, the Commodity Futures Trade Commission was forced to implement strict regulations to curtail such manipulative activity and restore market integrity.

These new regulations went so far as to prohibit brokers from profiting from wash trades even if they claimed to be unaware of their employing trader's true intentions, presumably because regulators believed that professional brokers should possess sufficient knowledge and implement adequate controls to detect such activity. This strict liability approach reflected the seriousness with which regulators viewed market manipulation.

In modern times, wash trading has made a significant return to the headlines of numerous financial publications and regulatory announcements, as the phenomenon of high frequency trading has become increasingly popular and technologically sophisticated throughout the global financial industry. High frequency trading, in essence, refers to the practice of using super high-speed computers and advanced algorithms to conduct trades at remarkable speeds—capable of executing upwards of several thousand individual trades per second from a single computing device. In the early 2010s, Bart Chilton, who served as Commissioner of the Commodity Futures Trading Commission at that time, was compelled to take action in response to growing concerns. He consequently announced his intention to thoroughly investigate such high-frequency trading activity to discover the various permutations of possible fraud and manipulation amongst high frequency traders and their algorithmic systems.

Because of the substantial lack of comprehensive regulation that continues to surround the cryptocurrency industry in many jurisdictions, crypto wash trading has successfully infiltrated its ranks and has been found to play a major and troubling role at many cryptocurrency exchanges worldwide. In fact, according to groundbreaking research published by the Blockchain Transparency Institute in the late 2010s, over 80% of the top 25 trading pairs for digital assets were found to involve wash trading to some degree, revealing the massive scale of market manipulation in the nascent cryptocurrency markets.

Conclusion

In summary, wash trading represents an activity that is fraught with serious regulatory danger and constitutes a borderline criminal action when conducted deliberately with manipulative intent. This is precisely why it is extremely important for all market participants—whether in traditional finance or cryptocurrency markets—to thoroughly understand what legally constitutes wash trading, how day trading and wash sales work in combination, and most importantly how to avoid becoming involved with such illegal activity yourself, either intentionally or inadvertently.

It is of paramount importance that traders, investors, and financial professionals not become caught up in the pursuit of short-term gains through wash trading schemes, lest their professional reputation and career be irreparably damaged through regulatory sanctions or criminal prosecution. In fact, even crypto wash trading, while operating in a less regulated environment, can severely damage a trader's reputation and credibility within the industry, although it may not technically be illegal in precisely the same way as traditional securities wash trading in all jurisdictions.

As is the case with virtually any intellectual or professional pursuit, the best and only sustainable option is to arm oneself with comprehensive knowledge and understanding of applicable regulations, as time and effort spent learning proper trading practices and compliance requirements is almost invariably valuable and protective in the long run. Wash trading, wash sales, and the traders who engage in them ultimately lower overall trust and confidence in financial markets and institutions, damage the integrity of price discovery mechanisms, and harm the livelihoods and investments of all honest participants in the financial ecosystem.

FAQ

What is Wash Trading (Wash Trading)? What is the difference between it and legitimate trading?

Wash trading is an illegal market manipulation where investors buy and sell the same securities to themselves, artificially inflating trading volume. Legitimate trading involves genuine transactions based on real market demand and price discovery without self-dealing or collusion.

What impact do wash sales have on tax reporting?

Wash sales disallow loss deductions for tax purposes, preventing you from claiming investment losses. However, the disallowed loss adjusts your cost basis for the repurchased security, deferring the tax impact rather than eliminating it entirely.

What is the definition of day trading (Day Trading)? What are the risks to note?

Day trading is buying and selling securities within a single day to profit from short-term price movements. Main risks include high leverage exposure, rapid market volatility, and potential significant losses. Requires careful risk management and experience.

What are the legal consequences and regulatory penalties for engaging in wash trading?

Wash trading in cryptocurrency can result in severe legal penalties including fines, criminal charges, and civil enforcement actions. Regulatory bodies may impose sanctions on individuals and platforms. However, the legal status varies by jurisdiction due to evolving and fragmented cryptocurrency regulations globally.

How to identify and avoid unintentional wash trading behavior?

Monitor unusual trading volume spikes and price volatility patterns. Wash trading typically involves large buy-sell activities in short timeframes.
