Citigroup faces $1 Billion lawsuit over alleged role in orchestrating and concealing fraud at Mexican Oil company Oceanografia, as U.S. appeals court revives case.

A U.S. federal appeals court has revived a long‑running, more than $1 billion lawsuit accusing Citigroup of orchestrating and concealing a large fraud tied to now‑bankrupt Mexican oil and gas services company Oceanografía S.A. de C.V. (OSA). Plaintiffs—about 30–39 vendors, creditors, bondholders and investment funds, including shipping and leasing firms and Rabobank—allege that Citigroup, mainly through its Mexican unit Banamex and related cash‑advance structures, advanced roughly $3.3 billion to Oceanografía between 2008 and 2014 based on receivables from Mexican state oil company Pemex, despite knowing Oceanografía was overleveraged and using forged Pemex documents. The Eleventh Circuit Court of Appeals found the plaintiffs had adequately alleged that Citigroup had knowledge of the fraud, substantially assisted it, and withheld critical information while benefiting from interest income on the advances, and therefore reversed a prior dismissal and sent the case back to the trial court in Miami. The case, known as Otto Candies LLC et al. v. Citigroup Inc., dates back nearly a decade and centers on a “cash advance” or receivables‑financing scheme tied to Oceanografía’s Pemex contracts. Oceanografía’s collapse in 2014 triggered large losses for creditors and prompted regulatory fallout for Citigroup, including the discovery of about $430 million in problematic advances, a $4.75 million U.S. SEC fine over internal controls, and the dismissal of Banamex employees later found criminally liable under Mexican law. The appeals ruling—and the U.S. Supreme Court’s later decision not to disturb it—means Citigroup must now face detailed fraud and aiding‑and‑abetting allegations in discovery and potential trial, with exposure that could reach $1 billion if liability is ultimately established. The case is significant both for Citigroup’s legal and reputational risk and as a test of how U.S. courts handle cross‑border fraud claims involving global banks, offshore creditors, and emerging‑market corporate collapses.
