Mariner Atlantic Files Swiss Criminal Complaint Against Radiant World and Seeks New York Banking Records

Mariner Atlantic Files Swiss Criminal Complaint Against Radiant World and Seeks New York Banking Records

New York investment fund Mariner Atlantic Multi-Strategy LLC has initiated criminal proceedings in Switzerland against international iron ore trader Radiant World, accusing the trading house, related entities, and founder Pinkesh Nahar of systematic fraud and money laundering. The complaint, lodged with prosecutors in Geneva, alleges that Radiant World generated fictitious commercial documents to simulate transactions and secure tens of millions of dollars in trade credit.

The development came to light through an application Mariner filed in the U.S. District Court for the Southern District of New York. In the U.S. filing, the fund is seeking court authorization to subpoena transaction records from the Federal Reserve Bank of New York and the Clearing House Interbank Payments System (CHIPS). Mariner has asked Swiss authorities to initiate a formal criminal inquiry, execute searches of Radiant World’s Geneva offices, and seize local bank accounts and corporate assets to prevent the further dissipation of funds.

Legal Topic

Area of Law: Cross-Border Commercial Litigation & Financial Crime

Sub-topic: Cross-Border Discovery / Trade Finance Fraud & Asset Recovery

Core Legal Issue

The controversy centres on whether an institutional creditor pursuing foreign criminal claims can use U.S. discovery mechanisms to compel disclosure of correspondent banking and clearinghouse data from major financial intermediaries.

At a substantive level, the dispute addresses the evidential threshold required to demonstrate that apparent trade-financing default disputes cross the threshold into criminal fraud and money laundering, particularly where trade instruments and invoices are alleged to represent non-existent underlying goods.

What Did the Court / Authority Decide?

Neither the U.S. federal court nor the Swiss prosecutor’s office has reached a final ruling on the merits. The proceedings are in their initial procedural phases:

  • In the United States: Mariner’s ex parte application in the Southern District of New York remains pending before the district court. The court has not yet granted or denied the subpoenas directed to the Federal Reserve Bank of New York and CHIPS.

  • In Switzerland: The Geneva Public Prosecutor’s Office has received the criminal complaint and petition for asset-freezing orders. Prosecutors have declined public comment, and no formal indictments or freezing orders have been announced.

  • Prior Judicial Action in Singapore: While the Swiss and U.S. matters are preliminary, the High Court of Singapore separately placed Radiant World under judicial management by KPMG following an application by Mizuho Bank, which also brought fraud allegations against the trading firm.

Key Legal Points

  • Use of U.S. Cross-Border Discovery: Creditors frequently utilize U.S. judicial assistance provisions to uncover correspondent dollar transactions flowing through New York clearinghouses, obtaining evidentiary trails that are otherwise shielded by foreign bank secrecy laws.

  • Criminal Complaint as an Asset-Tracing Vehicle: Filing a formal criminal complaint in Switzerland (plainte pénale) allows a private party to petition the state for urgent investigatory powers, including search warrants and bank account freezes.

  • Cross-Border Enforcement Web: The simultaneous invocation of Singapore insolvency procedures, Swiss criminal mechanisms, and U.S. federal court subpoenas highlights the coordinated multi-jurisdictional strategy required when tracing trade-finance assets.

  • Distinction Between Default and Fraud: The primary legal dispute turns on proving fraudulent intent and falsification of underlying transactions rather than a commercial inability to perform under trade finance arrangements.

Relevant Law

  • 28 U.S.C. § 1782: U.S. federal statute authorizing district courts to order discovery from entities residing in the district for use in foreign proceedings.

  • Swiss Criminal Code (Schweizerisches Strafgesetzbuch):

    • Article 146: Fraud (Escroquerie / Betrug) concerning intentional deception causing financial damage.

    • Article 305bis: Money Laundering (Blanchiment d'argent / Geldwäscherei).

  • Swiss Criminal Procedure Code (Code de procédure pénale suisse - CPC):

    • Article 115 & Article 263 CPC: Victim rights and the provisional seizure of bank accounts, records, and commercial assets.

  • Singapore Insolvency, Restructuring and Dissolution Act 2018 (IRDA): Governs judicial management orders and the displacement of management by court-appointed restructuring officers.

Arguments of the Parties

Petitioner / Applicant (Mariner Atlantic Multi-Strategy LLC)

Mariner argued that Radiant World and associated entities, including Sapphire Minmetals Corporation, engaged in an intentional scheme to fabricate bills of lading, contracts, and invoices to induce lenders into disbursing capital. The fund asserted that it advanced roughly $50 million under trade-finance facilities that it has been unable to recover, with the funds subsequently laundered through offshore and Swiss banking channels. Mariner contended that subpoenaing clearance records from the New York Fed and CHIPS is indispensable to untangling the flow of funds and presenting admissible evidence to the Swiss authorities.

Respondent / Opposing Party (Radiant World & Related Entities)

Radiant World has denied all allegations of fraud and wrongdoing, maintaining that its commercial activities and commodity trading were legitimate. Legal counsel and corporate spokespersons have maintained that the company's financial distress and defaults stem from market conditions rather than systemic falsification of trade paperwork. The Geneva prosecutor's office declined to confirm or comment on the scope of any pending investigatory actions.

Why Does It Matter?

This case demonstrates how creditors in distressed commodity finance cases deploy cross-border discovery tools as an evidentiary lever. Trade finance has historically faced vulnerability to "double-financing" and phantom shipment arrangements, where duplicate bills of lading are pledged to multiple institutions.

Because international commodities trade is predominantly settled in U.S. dollars, New York clearance hubs—notably CHIPS and the Federal Reserve Bank of New York—serve as critical nexus points. Even when transactions are initiated between entities based in Singapore, Dubai, or Geneva, the dollar-clearing footprint within the Southern District of New York gives foreign litigants a procedural mechanism to reconstruct financial flows. If granted, the discovery will establish a clear template for creditors looking to circumvent European banking privacy barriers through targeted U.S. correspondent banking subpoenas.

Legal Takeaway

Trade finance lenders facing recalcitrant debtors are increasingly pairing foreign criminal complaints with U.S. discovery actions to access correspondent banking data. Where dollar clearing occurs in New York, creditors have a practical mechanism to trace proceeds and support international asset-freezing applications before criminal courts.
