In the front-running equilibrium the information externality prevents investors from learning the value ofYt by the start of round iii, so their orders depend on Ytn and round-ii order flow which. indicates that investors are more willing to take speculative positions in round iii based on the private information in Y t n.

This arises because Yt shocks contribute to unexpected order flow in. round-iii that dealers use to quote prices in round iv. In a sense, the information externality created by front-running shifts. The plots show that the net e ff ect of the information conveyed by positive order flow is that investors increase their purchases of Forex in order to establish larger long speculative positions.

This effect is larger when investors have more precise private information on. Ytand when the degree of collusion is lower because in both instances the incremental information. However, all in all, it appears that equilibrium trading patterns are affected more by the presence of front-running than by the degree to which dealers engage in collusive front-running.

All other parameters are equal to the values in Table1 face as front-running makes round-iii prices susceptible to Ht shocks. In aggregate, this greater dependency means that Yt shocks have a larger negative impact on unexpected order flow, as shown in panel C. Similarly, the plots in panel D show thatHtshocks have a larger positive impact on order flow when there is more collusion among dealers. In this case, dealers use their shared information on hedgers orders, and the information in the investor orders they individually received in rounds iand iii.

In aggregate, this makes round-iii order flow more susceptible to Yt and Ht shocks, as can be seen in panels E and F. Index funds track a financial index by mirroring the index's portfolio. The composition of the index changes periodically in order to balance it accurately as the stocks that make it up change dramatically in price or as stocks are added or removed from the index.

That forces the fund's managers to buy or sell some components of the index. Traders watch the prices of those stocks, and they know when an index fund will update its components. They will front-run the trade by buying or selling shares to gain an edge.

This is not illegal because that information is available to all those who are paying attention. In , the Financial Industry Regulatory Authority FINRA announced penalties against Citadel Securities, arguing that the Chicago-based market maker had front-run against its own clients between and According to the financial regulator, Citadel removed hundreds of thousands of large OTC orders from its automatic trading processes, requiring those trades to be executed manually by human traders.

At the same time, Citadel "traded for its own account on the same side of the market at prices that would have satisfied the orders," violating their obligations to their clients. In a single sample month, FINRA found that Citadel had traded against their customers in nearly three-quarters of the inactive orders.

Yes, front-running is often illegal. Most types of front-running are prohibited by SEC Rule 17 j -1,. Payment for order flow PFOF is when a broker receives compensation for routing customer orders first to a particular market maker or trading firm. This practice has been criticized for discouraging best-execution for customers, but it is not considered front running since the firm receiving the flow will trade with the customer, not place trades going in the same direction in front of them.

Trading ahead is when a broker or market maker uses their firm's account to make a trade instead of matching available bids and offers from others in the market. Trading ahead is illegal, but it is not considered by regulators to be the same as front-running.

What Is Front-Running? How Front-Running Works. Front-Running FAQs. Investing Brokers. Key Takeaways Front-running is illegal and unethical when a trader acts on inside information. A straightforward example of front-running occurs when a broker exploits market-moving knowledge that has not yet been made public.

Abstract This paper examines the market-wide effects of front-running and information-sharing by dealers in a quantitive microstructure model of Forex trading. Recent investigations by gov- ernment regulators and court proceedings reveal that there has been widespread sharing of information among Forex dealers working at major banks, as well as the regular front-running of large customer orders.

I find that both forms of front-running create an information externality that significantly affects order flows and Forex prices by slowing down the process through which inter-dealer trading aggregates information from across the market.

These cost reductions are substantial; they lower costs by more than 90 percent. Front-running also affects other market participants that are not directly involved in front-running trades. The information externality makes these participants less willing to speculate on their private information when trading with dealers.

My analysis also shows that collusive front-running has larger effects on order flows than unilateral front-running because information-sharing reduces the risks dealers face when trading ahead of customer orders. However, in other respects, the effects of collusive and uni- lateral front-running are quite similar. Tel: email: [email protected] This research was undertaken independently without compensation. Foreign currency Forex trading appears to take place in a highly competitive environment.

Since the mids, major currencies have traded almost continuously between large numbers of counter- parties on multiple electronic platforms in high volumes and with very tight bid-ask spreads.

Between and reports issued by the U. Department of Justice, the Commodity Futures Trading Commission, New York Department of Financial Services, the U. Financial Conduct Authority, and the Swiss Financial Market Supervisory Authority all concluded that dealer-banks engaged in a range of collusive conduct aimed at manipulating the Forex bench- marks, specifically the ECB and WMR Fixes.

Following these reports, the U. This paper examines how the anti-competitive behavior identified by government regulators and enforcement authorities affects the spot Forex market. In particular, I use a quantitative microstructure model to analyze how the collusive sharing of information and front-running by dealer-banks impacts the behavior of Forex prices, trading flows and the welfare of all market participants.

According to the investigations and court proceedings, there has been wide-spread information-sharing among dealer-banks concerning their inventory positions and pending customer Forex orders i. I use the model to examine how such information-. CFTC Press Release No. FCA Press Release, FCA fines five banks 1.

FINMA Press Release, FINMA sanctions foreign exchange manipulation at UBS Nov. Johnson, No. The investigations also revealed that the dealer-banks regularly front-run large customer orders. For example, a dealer will buy Forex before executing a large Forex purchase on behalf of a customer with the aim of making a capital gain from the rise in prices produced by the execution of the large purchase.

The model I develop extends earlier multiple-dealer models of Forex trading in Lyons , Evans and Lyons andEvans The model describes trading between a large num- ber of dealer-banks hereafter dealers , and two groups of customers called investors and hedgers. Trading takes place between dealers in the wholesale tier of the market, and between dealers and their customers in the retail tier. Dealers are risk-averse and choose their trades and price-quotes optimally in both tiers of the market.

Investors are also risk averse and optimally determine the orders they place with dealers in the retail tier. In contrast, dealers receive orders from hedgers that are determined by an exogenous liquidity factor. The model provides a rich environment to study the market-wide effects of information-sharing and front-running. My analysis produces several noteworthy findings:. In the absence of front-running, the sharing of customer-order information among dealers increases the volatility of aggregate inter-dealer order flows but has little impact on equilibrium prices or the welfare of dealers and investors.

Risk-averse dealers have a strong incentive to unilaterally front-run their own customer orders, even when the execution of those orders has no impact on prices.

In an equilibrium where dealers have the opportunity to front-run their own customer orders, trading ahead of those orders creates an information externality that has significant effects on trading flows and prices. The externality slows down the process by which inter-dealer trading aggregates the information that is ultimately embedded into the prices, which in turn affects the trading decisions of both dealers and investors. Front-running reduces the costs dealers incur from providing liquidity to hedgers.

It raises the price hedgers pay when they are net purchasers of Forex, and reduces the price they receive. These effects are substantial.

Front-running also affects the welfare of dealers and investors. The information externality makes risk-averse investors less willing to speculate on their private information when trading with dealers, so they make smaller trading profits when that information becomes embedded in future prices. Collusive front-running has larger effects on aggregate inter-dealer order flows than unilateral front-running because information-sharing reduces the risks dealers face when trading ahead of customer orders.

In other respects, the effects of collusive and unilateral front-running are quite similar. Greater collusion lowers the costs of providing liquidity to customers, and it reduces investors trading profits, but the effects are small.

It is worth emphasizing that these results address the impact of information-sharing and front- running across the entire market. In particular, my analysis looks beyond the direct impact of shared information or front-running by individual dealers to consider their equilibrium effects on the trading decisions of other dealers and investors. This perspective counters the widespread assumption that the effects of front-running are not market-wide Kyle and Viswanathan, It is also empirically important because even though dealer information-sharing and front-running appear to have been widespread, it is unlikely to have directly involved more than a small fraction of all trades in the market.

The model shows that front-running by individual dealers has a market-wide impact because it creates an externality that affects how the information contained in external Forex orders becomes embedded in the prices dealers quote. In the absence of front-running, dealers trade in the wholesale tier to replenish their inventories after filling investor orders from earlier in the day. As in other models e. Front-running disrupts this process. When individual dealers learn about their future orders from hedgers, the information becomes an additional factor determining the trades they initiate with other dealers.

This means that the aggregate order flow produced by. Thus, front-running affects the determinants of aggregate order flow and its price-impact. This paper contributes to the literature on the manipulation of securities prices; originating with Hart , Vila , and Allen and Gale Its closest antecedents in that literature appear in the work on dual and predatory trading.

This irrelevance result counters the widespread intuition that dual trading must harm liquidity traders, as a monopolist will exploit information about liquidity trades that drive prices away from true asset values. However, the irrelevance result breaks down in a dynamic setting.

Bernhardt and Taub show that a monopolist with knowledge of current and future liquidity trades can gain by front-running future liquidity trades. In Brunnermeier and Pedersen , so-called predator traders sell ahead of or alongside the liquidating trader, before reversing their positions.

Bessembinder et al. My analysis contains elements of both the dual and predatory theories. Forex dealers act as dual traders insofar as they fill the external orders from customers in the retail tier and initiate trades with other dealers in the wholesale tier of the market. Dealers also could be viewed as engaging in predatory trading when they use the information on the pending external orders they receive from hedgers to trade strategically in the wholesale tier.

This paper is also related to research on Forex benchmarks, such as the WMR and ECB Fixes. Melvin and Prins drew attention to the fact that global portfolio managers have a strong. Manipulation via corners and squeezes is impractical for major currencies, while pump-and-dump schemes requiring the release of credible but false information that moves Forex prices are implausible.

Evans discussesthedifferencesbetweenthemanipulationofclosingequitypricesandForex benchmarks. According to the reports issued by government regulators, transcripts from electronic chat- rooms show that a number of dealers collusively front-ran the Fix orders they received from portfolio managers and others. In Evans , I found that Forex prices were unusually volatile around WMR pm Fix, and that Forex returns were negatively correlated either side of pm see, also Ito and Yamada, Furthermore, these empirical findings were inconsistent with a competitive model of Fix trading.

In that model, dealers do not front-run their Fix orders because the associated gain is offset by an endogenous change in the composition of the orders. In this paper, dealers can distinguish between customers who have price-insensitive reasons for trading i.

The front-running of selected customer orders is consistent with the evidence provided by government regulators and trial testimony. Osler and Turnbull also study dealer trading around the Fix in a model where trades are assumed to have a permanent price-impact that is proportional to the size of order flow. They emphasize that dealers trade strategically; front-running their own Fix orders and anticipating how the front-running by other dealers affects prices.

Strategic trading also plays an important role in my model because it determines how aggregate order flows convey information that dealers use to quote prices. The remainder of the paper is structured as follows: Section 1 presents the model. The next section examines the equilibrium where dealers have no opportunity to share information about or front-run their customer orders. This serves as a benchmark for the rest of the analysis. Section 3 introduces front-running. I first examine why dealers have an incentive to unilaterally front- run their own customer orders in the benchmark equilibrium.

Next, I analyze the equilibrium effects of unilateral front-running by all dealers. Section 4 considers the effects of collusive front- running where dealers share information about pending external orders. Section 6 concludes. I study the effects of dealer collusion and front-running in a standard microstructure model of OTC Forex trading. The overall structure of the model extends Evans with an additional round of trading and the inclusion of two types of Forex customers. This section presents the benchmark version of the model in which collusion and front-running are absent.

In the following sections, I introduce dealer front-running and collusion and study how these activities affect the equilibrium. Round I Payoff shock realized:! The model describes trading between a large number of dealers, investors, and hedgers over a trading day. Market participants comprise a continuum of investors, a continuum of hedgers, and a finite number of Forex dealers.

Both investors and dealers are risk-averse and choose their trades optimally, while hedgers trade for exogenous reasons. There are four rounds of trading each day; denoted as i, ii, iii and iv. Figure1 shows the sequence of events. Each investor n also receives foreign income, Yt.

This is private information to each investor and provides their motive for trading Forex.

To find this term, we compute the round-i order from investor n:. In step 2 I verify that the optimal trading decisions of dealers and investors produce these order flows. In other words, do dealers benefit from front-running at the expense of just hedgers i. Rearranging this equation produces A. Rohde, the acting U. Figure6shows that collusion among dealers has a much larger impact on the composition of order flows than on the intraday risk premia.
