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

Understanding Wash Trading: A Comprehensive Overview

All sorts of schemes exist in trade that skirt the very edge of legal activity, with some taking the plunge straight over the edge. Whether such actions are committed because of misadvice, greed, or simply as the result of hastily made and rash decisions, they can tarnish the reputation of an individual or firm irreparably. Wash trading is just such an activity, a form of day trading with enormous ramifications for the trader or traders involved. This practice represents one of the most serious violations in financial markets, carrying significant legal and reputational consequences for those who engage in it.

Understanding what exactly constitutes a wash trade and what makes them so poorly received in the financial industry is possibly the best defense against committing such a fraud. The complexity of modern financial markets, combined with the rise of high-frequency trading and cryptocurrency exchanges, has made wash trading an increasingly relevant concern for regulators and market participants alike.

In this article we'll examine the legal implications of wash trade, wash sales, and their effect on the day trading and cryptocurrency industries. Additionally, a brief history is provided to further clarify how such a practice became so well instituted into the world of finance, and why regulatory bodies have worked tirelessly to combat its proliferation.

What Is Wash Trading? Wash Trading Explained

Wash trading is where a securities transaction, or multiple transactions, are made to look like authentic purchases and sales – but when put under greater scrutiny, turn out to be fictitious. This deceptive practice undermines market integrity and creates false impressions of trading activity that can mislead other market participants.

This will usually occur when an investor buys and sells the same security or investment at the same exact time. The result of this is that a trader gives the appearance of trying to pass off a trade as having been made without actually making it, claiming a change to their portfolio when there has, in fact, been none. Wash trading is also sometimes called round-trip trading in the terminology of the financial industry, sometimes leading to further confusion for laymen.

In some cases, this is a direct and intentional attempt at market manipulation. Traders may engage in wash trading to create artificial trading volume, manipulate price discovery mechanisms, or generate false signals to other market participants. In others, wash trading can be the result of a more honest mistake, and simple ignorance on part of the trader attempting the transaction. However, regardless of intent, the consequences can be severe.

Wash trades usually refer to the practice of misreporting stock or security trade activity, but can also occur in the cryptocurrency industry. The practice has evolved alongside financial markets, adapting to new trading technologies and asset classes. No matter what area of finance you choose to trade in, centralized (CeFi) or decentralized (DeFi), it's essential to understand the potential implications of being involved in a wash trade.

In the case of deliberate wash trading, such an action usually takes place in order to influence buy and sell decisions – to the benefit of the trader or entity making the trade. Whether to give the appearance of increased price activity, or to spuriously influence trend line indicators used to analyze the market, wash trading is highly frowned upon by most regulatory bodies and market participants. The practice distorts market efficiency and can lead to significant financial losses for unsuspecting investors who base their decisions on manipulated data.

Is Wash Trading Illegal? Wash Trading Security Explained

In a nutshell, yes. Wash trading is illegal in most regulated financial markets around the world.

Wash trading is actively prohibited under the Commodity Exchange Act and the Securities Exchange Act of 1934. These landmark pieces of legislation were designed to protect market integrity and ensure fair trading practices for all participants. However, this can sometimes be a little difficult to enforce, as a sanctioning body must be able to prove intent and demonstrate that the prohibited activity actually occurred.

In fact, in order to legally assert that a wash trade has been made, one must establish two forms of precedent:

Intent: To legally establish that wash trading has been conducted in any form or fashion, the parties involved (usually a broker and an investor) must be proved to have entered into the trade deliberately. In this case, the adjudicators in question can reasonably assert that a wash trading violation was committed intentionally, in order to benefit one, or all, of the parties involved. This requires demonstrating that the trader knew they were engaging in wash trading and did so with the purpose of manipulating the market or deceiving other participants. Should this be found to be true, the regulators will take the necessary steps to reprimand those offending parties (or party), which may include substantial fines, trading bans, or even criminal prosecution in severe cases.

Result: As you might expect, the transaction under scrutiny must have resulted in a wash trade. By this definition, 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 relatively short span). They must also prove to be associated with the accounts that made the trade, or at least have some kind of beneficial ownership of the asset or security in question. This element focuses on the objective outcome of the trading activity, regardless of the trader's stated intentions.

Beneficial ownership refers to any disparate account that's owned by the same individual or entity at the time of making a trade. This concept is crucial in identifying wash trading because it allows regulators to connect seemingly independent transactions that are actually controlled by the same party. This is why trades made between two accounts with the same benefactor often draw attention from regulators, as it usually signifies some kind of illegal activity may be taking place. Modern surveillance systems and blockchain analysis tools have made it increasingly difficult for traders to hide beneficial ownership relationships.

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

In order to better understand what a wash sale is, the best method is perhaps to take a closer look at the clear-cut definition and its implications for day traders. While related to wash trading, wash sales represent a distinct concept with different regulatory treatment and consequences.

Wash sales are transactions or exchanges made, in which an investor sells a losing security (i.e. an asset they are likely to lose money on), in order to claim a capital loss. A capital loss, as it sounds, is where an asset or security decreases in value; however that value decrease is not actually realized until transactions are finalized. This creates an opportunity for tax manipulation that regulators have sought to prevent.

This means that a trader attempting to violate the wash sale laws can either:

  • Buy substantially the same assets or securities back again
  • Acquire substantially the same assets or securities in a fully taxable trade
  • Acquire an option to buy substantially the same securities

If the trader does this within the first 30 days of having made a sale, this is defined as an illegal wash sale. This 30-day window, known as the wash sale period, extends both before and after the sale date, creating a 61-day window during which investors must be careful about repurchasing similar securities. This will sometimes be the fault of pure ignorance, or a simple misstep on the part of the investor making the trade. However, more usually it is an attempt to realize a tax deduction, without eliminating market exposure to the asset or security being traded. In the next section we'll go over the Wash Sale Rule in order to better understand what constitutes a wash sale in day trading.

What Is the Wash Sale Rule in Day Trading?

The wash sale rule is a regulation issued by the Internal Revenue Service (IRS) preventing the average taxpayer from taking a deduction for a security sold during a wash sale. This rule represents one of the most important tax considerations for active traders and investors who frequently adjust their portfolios.

This rule covers all the aforementioned scenarios; whether the security is bought back, an option is bought back, or the security or asset is simply re-acquired via taxable trade, the result is the same. The disallowed loss is not permanently lost, however – it is added to the cost basis of the repurchased security, effectively deferring the tax benefit until the security is eventually sold without being repurchased within the wash sale period.

In addition, a sale will be considered a "wash" if an individual sells a security, and then the individual's spouse (or spouse's or individual's company) buys its substantial equivalent within that same 30 day time period. This extension of the rule prevents taxpayers from circumventing the regulation through related parties. The IRS has broad authority to look through various arrangements and identify wash sales even when they involve complex structures or multiple related entities.

Day traders must be particularly careful about the wash sale rule because their frequent trading activity increases the likelihood of inadvertently triggering a wash sale. Many trading platforms now provide wash sale tracking features to help traders avoid violations, but ultimate responsibility rests with the individual taxpayer.

Are Wash Sales Illegal? Wash Sales Security Explained

Now we have examined what a wash sale is, and the wash sale rule in day trading, the question turns to legality. While wash sales are not precisely illegal, writing it off as a capital loss in order to earn a tax break is, and is prosecutable by law. This distinction is important for traders to understand.

This precedent has been established in order to disincentivize companies or individuals from selling assets or securities at a loss simply for the purpose of tax deduction. The wash sale rule ensures that taxpayers cannot artificially create tax benefits by engaging in transactions that do not represent genuine changes to their investment positions. This means that, as long as one does not buy a substantially similar asset to the one they have sold at a loss (within 30 days), or better still does not write this transaction off as a tax deductive loss at all, one cannot be prosecuted for an illegal wash sale.

Some trouble can arise from the legal definition, however. This is because the IRS have not gone out of their way to define what they mean by "substantially similar" in legal terms. This ambiguity has led to considerable debate and litigation over the years. As a result, traders trying to avoid violating wash sale rules must look over various third-party provided guidelines and consult with tax professionals when dealing with complex situations.

One of the more helpful of these is the facts and circumstances test. In this test it's clearly stated that any investor should consider all facts and circumstances available to them in any specific case. This holistic approach requires examining the economic substance of the transactions rather than just their formal structure. By the IRS's guidelines, assets or securities from one corporation are not "substantially similar" to those of another, nor are bonds, preferred stocks, or anything of the like. However, securities within the same asset class from the same issuer would typically be considered substantially similar.

Is There Such A Thing As Cryptocurrency Wash Trading?

Unscrupulous brokerages engage in wash trading cryptocurrency with alarming frequency. The digital currency industry is, as things stand, woefully under-regulated – which has allowed the less palatable aspects of trade to flourish in its midst. This regulatory gap has created significant challenges for legitimate market participants and regulators alike.

In fact, according to some statistics in circulation, the problem of wash trading with cryptocurrency pairs is as prevalent – if not more so – than it ever has been in the certified financial industry. The pseudonymous nature of blockchain transactions, combined with the global and largely unregulated nature of cryptocurrency exchanges, creates an environment where wash trading can occur with relative impunity. This is because the tax laws that govern cryptocurrency follow the same guidelines as property tax laws in most countries, not of stocks and securities.

Wash trading cryptocurrency can take many different forms though, and is not just relegated to the trade of cryptocurrency pairs. The practice extends to various digital assets including tokens, stablecoins, and non-fungible tokens. Let's examine the practice of NFT wash trading, in order to get a better idea of how prevalent this practice has become in digital currency, and the scale of its proliferation.

What Is NFT Wash Trading?

According to multiple sources, many believe that the estimated substantial value generated in non-fungible token (NFT) sales in recent years may have been, at least partially, affected by wash trades. The NFT market's explosive growth has attracted both legitimate collectors and bad actors seeking to manipulate prices and create false impressions of value.

While it's extremely difficult to say this with a high degree of certainty, some examples are actually hiding in plain view. A blockchain monitoring company has noticed some worrying discrepancies emerging in recent months, leveraging the transparency of blockchain technology to identify suspicious patterns.

The company found cases where single NFTs had been sold to wallets (owned by the same individual selling the NFT in question) more than 25 consecutive times. The company's analysts assert that these are classic wash trading examples, and that in the just 110 profitable cases studied, the profits totaled almost 9 million dollars. This represents a significant distortion of the NFT market and demonstrates how wash trading can artificially inflate asset values.

The transparency of blockchain technology, while making it easier to identify wash trading after the fact, has not prevented its occurrence. The ability to create multiple wallets at minimal cost, combined with the lack of know-your-customer requirements on many platforms, makes NFT wash trading relatively easy to execute. However, as analytical tools become more sophisticated and regulatory frameworks develop, the risks associated with this practice are increasing.

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

Prior to becoming banned in 1936, wash trading was a commonplace activity amongst traders. The practice has deep historical roots in financial markets and has evolved alongside trading technology and market structure. Used to falsely signal interest to other rival investors, wash trades were (and in some ways, still are) a popular method used by market manipulators trying to pump up the value of a stock.

After the period of extremely combative, and profitable, trade following the Great Depression, the Commodity Futures Trade Commission were forced to regulate – and curtail such activity. The market crashes and widespread fraud of the early 1930s created public demand for stronger market regulation and investor protection. These regulations even prohibited brokers from profiting from wash trades even if unaware of their employing trader's intentions, presumably because it was thought that brokers should know better and have systems in place to detect such activity.

In modern times, wash trading has made its return to the headlines of many different financial publications, as the phenomenon of high frequency trading has become increasingly popular throughout the financial industry. High frequency trading, in essence, refers to the practice of using super high-speed computers to conduct trades – making upwards of several thousand trades per second from a single device. This technological evolution has created new challenges for regulators attempting to identify and prevent wash trading.

In the early 2010s, Bart Chilton (who was Commissioner of the Commodity Futures Trading Commission at the time) was forced into action. He consequently announced his intention to thoroughly investigate such activity to discover the permutations of possible fraud amongst high frequency traders. This investigation highlighted the challenges of applying traditional wash trading regulations to modern, algorithm-driven markets.

Because of the lack of regulation that surrounds the cryptocurrency industry, cryptocurrency wash trading has infiltrated its ranks, having been found to play a major role at many exchanges. In fact, according to research published by the Blockchain Transparency Institute, over 80 percent of the top 25 trading pairs for Bitcoin were found to be wash traded in past years. This staggering statistic demonstrates the magnitude of the problem and the urgent need for regulatory intervention in cryptocurrency markets.

Conclusion

In summary, wash trading is an activity that is fraught with regulatory danger, and a borderline criminal action if deliberate. This comprehensive examination has revealed the multifaceted nature of wash trading and its various manifestations across traditional and digital asset markets. This is why it's extremely important to understand what constitutes wash trading, how day trading and wash sales work combined, and how to avoid getting involved with such activity yourself.

It's of paramount importance that a trader not get caught up in the pursuit of wash trading, lest their professional reputation be irreparably damaged. The consequences extend beyond individual traders to affect market integrity, investor confidence, and the efficient functioning of financial markets. In fact, even cryptocurrency wash trading can damage a trader's reputation, although it's not technically illegal in the same way in many jurisdictions, the ethical implications remain severe.

As is the case with almost any intellectual pursuit, the best and only option is to arm oneself with knowledge, as time spent learning is almost invariably valuable in the long run. Understanding the nuances of wash trading, wash sales, and related market manipulation techniques provides essential protection for traders and investors. Wash trading, wash sales, and the traders that engage in them, lower overall trust in the financial industry, and damage the livelihoods of all involved. By maintaining high ethical standards and staying informed about regulatory requirements, market participants can contribute to fairer, more transparent markets for everyone.
