Mirror trading
What is mirror trading in money laundering?
A mirror trade is a pair of matched orders in the same security. One customer buys it for local currency in one office while a connected customer sells the same amount for dollars in another, at the same time and price. Nothing is really invested. The pair works as a currency swap that moves value across a border without an obvious wire.

What is mirror trading?
Imagine two customers of the same bank. One is in Moscow. The other is a company registered offshore. On the same day, at the same price, the Moscow customer buys a block of a well-known Russian company’s shares and pays in rubles. The offshore company sells the identical block and is paid in US dollars. When both trades settle, the shares have made a small round trip and everyone is roughly where they started, with one exception: the value of the rubles has become dollars, outside Russia.
That pair is a mirror trade. Each half is ordinary. Buying and selling liquid shares is what a trading desk does all day. It is only the two halves together that reveal the purpose: a covert currency swap across a border.
It belongs to the layering stage. Nothing needs to be placed into the financial system, because the money is already in it. The point is to change its currency and its location, and to swap a suspicious cross-border transfer for two trades that look routine. The glossary entry on mirror trading gives the short definition. (The same phrase is also used in retail investing for copying another trader’s positions. That has nothing to do with laundering.)
How does a mirror trade work?
- A person or company wants to move money out of a country, perhaps to avoid currency controls, taxes, or questions about where the money came from. It needs a bank with a local trading desk and a foreign one.
- The customer on the local side opens an account with the bank’s local office. A connected customer, often offshore and non-local, is signed up with the same bank. In the Deutsche Bank case, the second customers were onboarded through the Moscow front office.
- On the local side, the first customer places an order to buy a liquid security and pays in local currency.
- At the same time, the offshore customer places an order to sell the same amount of the same security to the bank’s foreign book, and is paid in dollars or euros.
- Both trades settle. The bank earns commission, if any, and the shares stay with the bank. The offshore customer now holds hard currency abroad, and can send it on to accounts in third countries.
- The pair is repeated many times, usually across many customers, so a large sum moves in slices that each look small.
Why does mirror trading work?
It works because each trade looks like normal business. The security is liquid, the price is the market price, the settlement is real, and no one sends a wire from one customer to the other. A monitoring system tuned to catch structured cash deposits or odd wires may not see anything at all.
It also depends on separation. In the Deutsche Bank case, the two sides were placed in different offices and different legal entities, and the bank’s own control systems did not join them up. The FCA found the trades were undetected for a long time because of widespread weaknesses in customer onboarding and in ongoing monitoring of trades.
Customers can hide behind intermediaries, too. The FCA found the mirror trading customers traded on behalf of undisclosed underlying clients, and that the bank did not verify ownership. When a bank does not know who is behind a trade, it cannot tell that the two sides are related, or that a blue-chip stock trade has no economic sense.
Last, the incentives can mislead. A desk that earns fees on both legs sees a client relationship, not a warning sign. The regulator described how front-office staff did not see themselves as ultimately responsible for knowing the customer, and how compliance teams were understaffed.
Real case: Deutsche Bank’s Russian mirror trades
The public record on this technique comes mostly from the Deutsche Bank case, which is covered in full on the cases page. The FCA’s Final Notice describes the arrangement in plain terms. A Russian customer of Deutsche Bank’s Moscow subsidiary bought liquid Russian securities and paid in rubles. At the same time, a non-Russian customer sold the same number of the same securities to Deutsche Bank for US dollars. The customers on the two sides were connected, and the amount and value of the securities were the same, so the evident purpose was the conversion of rubles into dollars and the covert transfer of funds out of Russia.
The FCA counted more than 2,400 mirror trades between April 2012 and October 2014, moving more than US$6 billion through Deutsche Bank in the UK to overseas accounts, including in Cyprus, Estonia, and Latvia. It also found about 3,400 one-sided trades, worth US$3.8 billion, that were almost all sales. It considered these the visible half of further mirror trades, and said the whole flow came to about US$10 billion.
The Notice also lists the missed chances, and they matter more than the numbers. London staff asked about the mirror trading customers three times between December 2012 and January 2014 and did not follow up on unclear answers. In January 2014 a third-party bank asked Deutsche Bank about wires of roughly US$444 million in 2013 and US$252 million in January 2014 to one of the customers, and Deutsche Bank did not respond for weeks. In June 2014 an internal reviewer noticed a customer’s trades produced no commission and asked if another leg was missing; no reply came. In August 2014 the Moscow back office spotted a mirror trade arrangement and escalated it. A response from the Moscow AML team said it was “strongly convinced” the customers were part of one laundering scheme with no economic sense behind the trades. The bank’s AML team closed some accounts in October 2014, but the customers used multiple identities, and a wider review did not happen until February 2015.
On January 30, 2017, New York’s financial regulator announced a US$425 million penalty and an independent monitor. On January 31, 2017, the FCA announced a fine of £163,076,224, and called it the largest AML fine it or its predecessor had imposed. Both were regulatory penalties for control failures. As the FCA noted, there was no evidence that senior management or UK staff knew of the suspicious trades.
How does mirror trading get caught?
Detection is a data problem. Each half of the pair is invisible alone. The pair becomes visible when a surveillance system can compare orders across offices, currencies, and legal entities. The relevant patterns are the ones in the FCA’s findings: identical size, security, and price, executed at the same moment, for customers with shared owners or addresses, and no risk of profit or loss.
Know-your-customer work is the second line. If the bank verifies who owns each customer and asks why a customer is trading, then two apparently unrelated companies with the same owner stand out. The FCA found none of that was done properly: ownership was not independently verified, source of funds rested on unverified CVs, and no customer documented the purpose of the relationship. See the detection overview for how customer due diligence and monitoring fit together.
The third line is people. In the Deutsche Bank case, questions from a third-party bank and from staff were the closest thing to an alarm. They were also the moments the bank failed to act on. A control works only if someone owns the alert and has the standing to stop a profitable client. Investigators now ask trading desks the same question they ask branches: who is behind this customer, and what is the reason for this trade?
Frequently asked questions
Is mirror trading the same as copy trading?
No. In retail investing, mirror or copy trading means automatically copying another trader's positions. In money laundering, a mirror trade is a matched buy and sell placed by connected parties so that value changes currency and country. The two share a name and nothing else.
Why use shares instead of a bank transfer?
A direct transfer of billions out of a country can trigger currency controls, reporting, and bank questions. A trade in liquid blue-chip shares looks like ordinary market activity, settles normally, and shows up as a trade, not as a transfer. That routine look is the disguise.
Did the bank knowingly help launder money?
The FCA found the failings were not deliberate or reckless and said it saw no evidence that senior management or UK staff knew about the suspicious trading. The findings were about weak controls: the bank could not verify who its customers were or where their money came from.
Were the customers convicted?
The regulators' announcements describe penalties against the bank for control failures. They do not describe criminal convictions of the customers, and the source of the money was never established in those findings. Treat the trades as highly suggestive of financial crime, in the FCA's words, not as proven crimes by named people.
Cases that used this technique
- Deutsche Bank Mirror Trades · Deutsche Bank's Moscow and London desks ran matching stock trades that turned rubles into dollars offshore, moving about US$10 billion out of Russia and drawing fines from New York and London in 2017.

Related techniques
- Correspondent banking and wire layering · Small or weakly supervised banks reach the dollar system through accounts at big correspondent banks, and rapid wires through many accounts and countries bury the origin of the money.
- Securities and brokerage · Brokerage accounts, offshore nominee accounts, and thinly traded microcap stocks can move and disguise value, because markets shift money instantly and legitimately.
- Shell companies and nominees · Companies with no real operations hold accounts and assets while nominee directors and stacked ownership across jurisdictions hide the true beneficial owner.
- Trade based money laundering (TBML) · Moving value across borders through trade paperwork: over- or under-invoicing goods, double-invoicing shipments, or invoicing shipments that never happened.
