Round-tripping and fake foreign investment

As of September 2026: The statistics on this page are estimates from published research and vary by year and method. The 2024 India-Mauritius protocol had been approved by Mauritius's Cabinet on July 17, 2026 but, according to EY's July 2026 alert, had not yet entered into force. Check current treaty status before relying on it.

Also called: round tripping · FDI round-tripping · round-trip investment · phantom foreign investment.

What is round-tripping?

A round trip is simple to describe. Money leaves a country. It sits for a while in an offshore company. Then it comes back, this time labelled as foreign investment, a foreign loan, or income from abroad. The owner is the same at both ends. Only the label on the money has changed.

The label is valuable for two different reasons. The first is legal. Many countries treat foreign investors better than local ones, with tax breaks, treaty protection, and easier access to courts. The second is concealment. Funds that come from a foreign investor look clean, while funds that come from a domestic person raise questions about where they were earned. In laundering, this is the layering step moving toward integration: the money is reintroduced to the home economy with a respectable story.

Round-tripping is not always crime. That point matters. Statisticians at the IMF and OECD study round-tripping mainly as a data problem, because it inflates the amount of “foreign” investment in a country. Some owners round-trip capital to gain a tax advantage, to shelter it from weak courts, or to work around exchange controls. Others do it to disguise proceeds of corruption. From the outside, the two look alike, which is exactly what makes the technique useful to launderers and hard for investigators.

How does round-tripping work?

1. The owner has funds in the home country. They may be dirty, untaxed, or simply restricted. They are moved abroad through a bank transfer, trade invoices, or another route.
2. The owner sets up, or already controls, a company in another jurisdiction. It is often a shell company in a treaty partner or low-tax centre, sometimes with nominees on the paperwork.
3. The funds are held in the offshore company, sometimes for months or years, sometimes only long enough to break the link.
4. The offshore company invests in or lends to a company in the home country. That company may be the owner’s own business, a new venture, or a property holder.
5. The money returns. On the home country’s books it is a foreign investment or a foreign loan, coming from a company in a friendly jurisdiction.
6. The owner benefits twice: the money has a clean-looking source, and the investment may qualify for treaty, tax, or legal treatment the owner could not claim as a resident.

Why does round-tripping work?

It works because inbound foreign money is welcomed. Governments compete for foreign investment and often report it as a success. A bank or regulator looking at a stake bought by a Cypriot or Mauritian company sees a foreign investor, and unless it traces the beneficial owner behind that company, the story holds.

Official statistics can also hide it. The IMF’s expert group noted that under the standard rules, round-tripped funds are recorded as direct investment abroad on the way out and direct investment in the economy on the way back, because the statisticians follow the legal structure and not the owner. The World Bank added that companies involved often do not want to reveal the true nature of the flows, so surveys can miss it.

Treaties and incentives supply the motive. The World Bank paper explained how an old India and Mauritius tax treaty gave only Mauritius the right to tax certain share gains, and Mauritius did not tax them, so Indian companies based there could avoid tax in both places. It attributed about 10% of India’s FDI inflows over a decade to round-tripping through Mauritius, a strategy used for tax evasion and, in some cases, money laundering. Where the incentive disappears, the flows shrink. After China removed tax advantages for foreign investors, the same paper reported round-tripping between China and offshore centres fell to an estimated 14% of its FDI in 2010.

Where it shows up: Russia, Ukraine, China, India

Round-tripping is mostly documented through statistics and research rather than single prosecutions, so this section reviews what the evidence shows. It does not name a single case, and none should be assumed guilty from the numbers alone.

The clearest signal is a mirror-image pattern in the numbers. The World Bank reported that Cyprus and other offshore financial centres accounted for around 70% of Russia’s inward and outward FDI stock in 2014, and that Cyprus led as both the main destination and the main source of Russian FDI. For Ukraine, Cyprus supplied nearly 30% of FDI inflows while also holding 92% of Ukraine’s outward FDI stock. A small island is an unlikely main genuine investor in two large countries, which is why researchers suspect much of that flow is domestic money returning.

Why it happens differs by country. In Russia, the paper found that avoiding domestic regulatory uncertainty played a bigger role than tax breaks. It also described research introducing the idea of “secrecy arbitrage”: some round-tripped capital is licit money hiding from corrupt authorities, and some is proceeds of corruption laundered offshore and reinvested at home. The totals alone cannot separate the two.

China’s case shows the tax-motive version. Hong Kong statisticians told the IMF that 40% of Hong Kong’s inward FDI in 1998 to 2002 was related to round-tripping. An ADB Institute paper in 2004 estimated that between 30% and 50% of recorded FDI in China was round-tripped. These are estimates, and researchers used different methods, but they point the same way.

India shows how a fix works. India and Mauritius signed a protocol on May 10, 2016 that changed the tax treatment of gains on shares acquired from April 1, 2017 and added anti-abuse provisions. In March 2024 they signed a further protocol adding a principal purpose test, which asks whether getting the tax benefit was the main reason for routing an investment through Mauritius. As of September 2026, EY reported the 2024 protocol had Mauritian Cabinet approval but had not yet entered into force.

One limit is worth stating plainly. A statistical pattern is a lead, not a verdict. A bank or investigator who sees a Cypriot investor in a Russian company has learned where to look, and nothing more. The evidence that matters is the trail behind the offshore company: who paid for it, who controls it, where its money came from, and whether the same people sit on both ends of the deal. Only that trail separates a legal tax arrangement from a laundering loop, and the answer can be different for two investors using the same jurisdiction.

How does round-tripping get caught?

The main tool is ownership transparency. Round-tripping falls apart once the foreign investor’s real owner is known. Banks that follow know-your-customer rules are expected to look through the offshore company to the person behind it, and to ask why that person is investing at home through a foreign vehicle. Beneficial ownership registers, where they exist and are checked, do the same job at national scale.

The second tool is statistics. The OECD’s fifth Benchmark Definition addresses round-tripping through an ultimate investing economy view, which reassigns investment to the country whose owner ultimately controls it. That will not identify a criminal, but it exposes how much “foreign” money is homegrown, which points supervisors at the right corridors.

The third tool is closing the incentive. Treaty anti-abuse rules, such as the principal purpose test, limit benefits for structures set up mainly to obtain them. Removing the special treatment reserved for foreign investors, as China did, weakens the reason to disguise domestic money as foreign in the first place.

Inside a bank, the signs are practical: an investor with no substance, a loop of funds that leaves and returns in a similar amount, and an owner who will not say who is behind the offshore company. Those are grounds for questions and, where the answers do not hold, a suspicious activity report. See the detection overview for how those reports are used.
