Mozambique's Tuna Bond Scandal: $2 Billion in Secret Debt
Mozambique was told it was buying security for its coast and jobs for its young state; instead, it signed secret guarantees that turned fishing dreams into a billion-dollar deception. When the paper trail finally surfaced, the debt had already been fished out of the dark and the bill was heading straight for the public.

Timeline
Ematum Financing Takes Shape
**2013-03** — Mozambique’s tuna and maritime project enters the international financing market under a commercial-development narrative. The debt is structured in a way that will later be examined as a concealed sovereign obligation.
First Bond Placed
**2013-09** — The first major tranche tied to Ematum is issued and sold with backing from international banks. The transaction gives the appearance of private project finance even though the state’s role is central.
Recruitment of Market Confidence
**2013-12** — The financing is circulated through bank and investor networks using official sponsorship and development language as trust signals. The deal begins to gain social proof simply by being completed.
Fee and Flow Structure Hardens
**2014-06** — As the borrowing structure matures, attention turns to how proceeds are being allocated and what assets actually exist. The mismatch between the public story and the project economics becomes harder to ignore.
Internal and External Questions Mount
**2015-11** — Auditors, journalists, and market participants begin asking how much debt Mozambique has actually taken on and whether the liabilities were properly authorized. The paper trail becomes a liability in itself.
Hidden Guarantees Disclosed
**2016-04** — Mozambique publicly acknowledges previously undisclosed state guarantees tied to the tuna and maritime borrowings. The disclosure turns a financing story into a national fiscal crisis.
IMF and Donor Pressure Intensifies
**2016-05** — International lenders and donors demand clarity on the debt and suspend or reassess support. The country’s currency and budget come under severe stress.
U.S. Charges Announced
**2018-12-2018** — The U.S. Department of Justice announces charges in connection with the Mozambique fraud scheme. The case becomes an international criminal prosecution rather than only a debt scandal.
Manuel Chang Detained
**2018-12-29** — Chang is arrested in South Africa while transiting through Johannesburg, beginning a prolonged extradition dispute. His detention gives the scandal a concrete defendant and a custody battle.
Civil and Criminal Proceedings Expand
**2019-12** — Investigations and related cases continue in the United States, Switzerland, the United Kingdom, and Mozambique. The legal theory of the scandal becomes established across multiple jurisdictions.
Bank Settlements and Deferred Prosecution
**2021-10** — Credit Suisse and related entities resolve major U.S. and U.K. enforcement actions arising from the hidden debt matter. The settlements confirm the central role of banking misconduct and weak controls.
Legacy Litigation Continues
**2023-03** — Residual claims, appeals, and asset-recovery efforts continue, with full restitution still elusive. The scandal remains a live example of how sovereign fraud outlasts the headlines that expose it.
