In 2013, Mozambique was a country trying to write a new economic story for itself. Offshore gas discoveries had turned the Indian Ocean coastline into a promise line, and officials in Maputo were eager to present the state as an emerging hub rather than a postwar borrower dependent on donors and commodity luck. That ambition mattered. It created the atmosphere in which a deal that should have looked absurd instead looked, to some inside the government, like statecraft.
The setting was not abstract. It was Maputo in the years after the civil war, when ministries were still building the habits of a functioning state and when the language of development could be used to cover a great deal of financial improvisation. In that environment, a project framed as maritime modernization could pass as industrial policy, and a debt structure could be made to look like a commercial opportunity rather than a sovereign obligation. The appearance of progress was itself part of the mechanism.
The central figure on the government side was Manuel Chang, Mozambique’s finance minister. He had the authority, the signature, and the proximity to the machinery of the state that made debt possible. According to later court filings and congressional investigations, Chang and other officials approved or facilitated a hidden borrowing structure that bypassed normal disclosure and parliamentary scrutiny. The public story was that Mozambique was financing maritime security and a tuna-fishing enterprise. The private reality, alleged in U.S. and Swiss proceedings and later acknowledged in guilty pleas by some participants, was that the state was being asked to stand behind loans arranged in secret.
The institutional environment was ripe for abuse. Mozambique’s public financial controls were weak, external oversight was limited, and the international banking system had grown comfortable exporting complex credit to frontier states so long as the paperwork was just plausible enough to clear the next desk. This was not a scheme built on one forged signature alone. It was a structure assembled across ministries, banks, and intermediaries, each layer giving the next a reason not to ask too many questions. The danger lay not only in the amount of money, but in the way the transaction was normalized through procedure.
The first deal took shape around a company named Ematum, short for Empresa Moçambicana de Atum. On paper, it was meant to buy tuna boats, build a fleet, and create employment. In practice, it became the vessel through which a much larger borrowing campaign would move. The first tranche, completed in 2013, totaled about $850 million. Later the state would acknowledge that more of the same architecture had been extended through additional borrowing, bringing the total secret debt associated with the tuna and maritime projects to roughly $2 billion. What began as a fisheries company was evolving into a shadow financing vehicle of exceptional scale.
The financing was packaged in a way that mattered as much as the amount. Credit Suisse and VTB Capital were among the arrangers identified in civil and criminal proceedings. The debt was not marketed as ordinary sovereign borrowing, but as a commercial transaction tied to fishing and security assets. That framing allowed the loans to be treated as something less visible than direct government debt, even though the government had effectively guaranteed them. The gap between the legal form and the economic reality was the opening through which the fraud walked. The architecture depended on a distinction that was technical on paper and catastrophic in substance.
The record shows how carefully the structure was dressed up. There were spreadsheets, term sheets, ministry approvals, and legal instruments moving through a chain of officials and intermediaries. There were enough signatures to create the impression that each step had been checked somewhere above and beyond the person who initialed the previous page. In a system where responsibility could be diffused across offices and jurisdictions, the absence of public disclosure was not a side issue; it was the condition that allowed the transaction to exist at all.
A scene from the beginning captures the scale of the illusion. In the offices where the transaction was being assembled, advisors and bankers were dealing with spreadsheets, term sheets, and ministry approvals, while in the harbors and ministries of Mozambique there was still no operational fleet that matched the financing story. The boats, patrol craft, and support systems were promises before they were assets. The money had a destination in theory before it had one in fact. The project existed first as a set of documents and only later, if at all, as a functioning maritime enterprise.
That mismatch carried obvious stakes. A poor country with existing debt constraints was being pushed into obligations that were not being fully disclosed. If the borrowing had been properly surfaced through parliamentary scrutiny and standard public reporting, the political and fiscal consequences would have been immediate. Investors, donors, and domestic institutions would have had a chance to ask what Mozambique was actually buying, on what terms, and with what repayment capacity. Secrecy removed that checkpoint. It let the state accumulate risk without an honest reckoning of the balance sheet.
What made the scheme move from concept to operation was not just greed, although court records later pointed to kickbacks and undisclosed fees. It was trust in institutional camouflage. A ministry stamp. A bank syndicate. A foreign law firm. A London listing for part of the paper trail. Enough official texture to make the transaction feel handled, not hidden. The details were designed to resemble ordinary finance, even as they concealed an extraordinary assumption of sovereign liability.
The tension in this chapter of the scandal is that the concealment was not sophisticated in every sense; it was sophisticated only in its willingness to exploit weak points that already existed. The public-facing narrative was simple and attractive: fisheries development, maritime protection, and modern state capacity. That language lowered the temperature of scrutiny. It made the borrowing sound like nation-building rather than liability transfer. But the deeper the paperwork ran, the more the hidden guarantee mattered. Once the state was on the hook, the distinction between a private vehicle and a public debt evaporated.
By the time the first loan documents were signed, the state guarantee had done its work. The money could flow. And once it began to flow, it would not stay where the public believed it was going. The line between fisheries investment and hidden sovereign debt had already been crossed; the only question left was who would notice first, and how long it would take for the numbers to betray the story. When that reckoning came, it would not begin with one dramatic disclosure. It would begin with the slow, forensic realization that the paperwork, the guarantees, and the financing structure all pointed to the same conclusion: Mozambique had been made to carry obligations it had never been allowed to see in daylight.
