Rusal & OFAC Sanctions 2018 : How One Man’s Designation Crashed the Global Aluminum Market — EP75 T1 29.05.2026

This is the financial autopsy of the Rusal sanctions event — how the application of OFAC’s 50% rule to a company producing 7% of world primary aluminum (and 17% outside China) created the largest commodity market shock since the financial crisis. We dissect the full sequence: the visible ownership chain, the transmission mechanism through dollar payments, logistics and insurance, the market’s comp...

Rusal 2018 : Beneficial Ownership Transmission & Commodity Supply Chain Risk │ GP/LP Analysis — 3 Red Flags │EP75 T2 29.05.2026

This GP/LP technical episode dissects the beneficial ownership transmission mechanism in commodity supply chains and how a single individual designation can trigger systemic disruption. We identify three critical red flags for commodity and trade finance exposure: (1) beneficial owner political exposure combined with high supply concentration, (2) dollar payment dependency of the supplier, and (3)...

Petrobras & Lava Jato 2018 : How Brazil’s Largest Company Became a Political Kickback Machine — EP74 T1 28.05.2026

This is the financial autopsy of Operation Car Wash (Lava Jato) — the largest anti-corruption investigation in Latin American history. What began as a small money laundering probe at a currency exchange in a Brasília gas station uncovered a systemic kickback scheme inside Petrobras that moved at least $2 billion in bribes, affected $42 billion in contracts, produced over 200 convictions, and impli...

Petrobras & Lava Jato 2018 : Political Appointment Capture & State-Owned Kickback Architecture │ GP/LP Analysis - 3 Red Flags│EP74 T2 28.05.2026

This GP/LP technical episode dissects the political appointment capture mechanism that turned Petrobras into a systematic extraction vehicle for Brazil’s governing coalition. We identify three institutional-grade red flags visible before the scandal exploded: (1) directorate appointments correlating with political cycles rather than operational expertise, (2) statistical anomalies in contract awar...

Pandora Papers 2021 : How the United States Became One of the World’s Most Effective Offshore Secrecy Jurisdictions — EP73 T1 28.05.2026

This is the financial autopsy of the Pandora Papers — the leak of 11.9 million documents from 14 offshore service providers that revealed how political elites and wealthy individuals moved assets into trust structures in South Dakota, Nevada, and other US states after the Panama Papers increased pressure on traditional offshore jurisdictions. We dissect the full story: how South Dakota abolished t...

Pandora Papers 2021 : Trust Architecture vs Shell Company Due Diligence │GP/LP Analysis - 3 Red Flags│EP73 T2 28.05.2026

This GP/LP technical episode breaks down the trust architecture mechanism: settlor-directed trusts, protector roles, perpetual duration, and the absence of public registries. We identify three key red flags for modern counterparty due diligence: documentary gaps at onboarding, jurisdictional incoherence between trust location and economic activity, and the protector mechanism as hidden control. We...

Panama Papers 2016 : The Law Firm That Built the Infrastructure for Global Financial Concealment — EP72 T1 27.05.2026

This is the financial autopsy of the Panama Papers — the largest data leak in history. Mossack Fonseca, a single Panamanian law firm, incorporated over 300,000 offshore companies for clients in more than 200 countries, including 140 politicians and 12 heads of state. We dissect how anonymous corporate structures, nominee directors, and jurisdictional migration became a commercial product sold for...

Panama Papers 2016 : Offshore Shell Infrastructure & Beneficial Ownership Gap │GP/LP Analysis - 3 Red Flags │EP72 T2 27.05.2026

This GP/LP technical episode breaks down the offshore incorporation architecture that made beneficial owners invisible by design, and delivers the active verification framework every capital markets professional needs today. We identify three observable red flags in corporate structures: beneficial ownership gaps, nominee director patterns, and suspicious jurisdictional choices. We provide the pra...

HBOS Reading 2007 : The Bank Division Created to Save Businesses Was Used to Destroy Them — EP71 T1 27.05.2026

This is the financial autopsy of the HBOS Reading fraud — one of the most shocking cases of internal bank predation in UK history. A senior director weaponized the bank’s own Impaired Assets division, referring distressed clients to a corrupt consultant who extracted fees, stripped assets, and pushed hundreds of businesses into collapse. We dissect the full sequence: how the referral channel was c...

HBOS Reading 2007 : Referral Channel Capture & Workout Function Risk │GP/LP Analysis — 3 Red Flags │EP71 T2 27.05.2026

This GP/LP technical episode analyzes how one director at HBOS Reading controlled client classification, consultant referrals, and credit approvals, converting the bank’s own help channel into a systematic extraction operation. We identify three critical red flags for any specialized distressed lending or workout function: referral concentration, fee-to-facility ratios, and outcome benchmarking. T...

TD Bank 2024 : The Bank That Grew Fastest in North America But Kept Its AML Budget Flat for a Decade — EP70 T1 26.05.2026

This is the financial autopsy of TD Bank — the largest Bank Secrecy Act violation in US history. Between 2014 and 2024, TD Bank intentionally excluded 92% of its transaction volume from automated monitoring while aggressively growing its US retail footprint. The result: more than $670 million in drug cartel proceeds moved through the bank, a $3 billion penalty, a guilty plea to conspiracy to commi...

TD Bank 2024: AML Program Adequacy vs Flat Cost Paradigm │GP/LP Analysis - 3 Red Flags │EP70 T2 26.05.2026

This GP/LP technical episode dissects the institutional failure: how a flat compliance budget applied to a rapidly growing retail bank created a structural monitoring gap that excluded 92% of transaction volume, despite prior 2013 enforcement actions and repeated internal audit warnings. We identify three critical red flags visible before the 2024 settlement: (1) the 2013 FinCEN/OCC enforcement ac...

GPB Capital 2018 : The Auditor Resigned. The FBI Raided. Seventeen Thousand Retail Investors Lost $1.8 Billion — EP69 T1 26.05.2026

This is the financial autopsy of GPB Capital Holdings — the Regulation D private placement fund that raised $1.8 billion from 17,000 retail investors (many seniors) promising 8% annual distributions through sixty-plus broker-dealers. The product paid high commissions (8%), but the underlying auto dealerships and waste management companies could not generate enough income to cover the distributions...

GPB Capital 2018 : Distribution Coverage Ratio Failure & Broker-Dealer Due Diligence Gaps │GP/LP Analysis - 3 Red Flags│EP69 T2 26.05.2026

This GP/LP technical episode dissects the full mechanism: the Reg D disclosure gaps, the commission-to-yield mismatch, the auditor resignation signal, and the structural incentives that allowed the product to reach thousands of retail investors. We identify three institutional-grade red flags available before the 2018 auditor resignation: (1) the unsustainable commission structure relative to prom...

Signa Group 2023 : The Buildings Were Real But the Rents Came From Its Own Losing Companies. The Valuations Were Circular — EP68 T1 25.05.2026

This is the financial autopsy of Signa Group — the largest real estate collapse in Europe since 2008. René Benko built a €27 billion portfolio of prime assets (KaDeWe, Selfridges, Chrysler Building) by charging above-market rents from his own retail subsidiaries (Galeria Karstadt Kaufhof, Kika/Leiner, Globus) to inflate property valuations. Those inflated values supported approximately €13 billion...

Signa Group 2023 : Circular Valuation Architecture & Related-Party Rent Mechanism │GP/LP Analysis - 3 Red Flags│EP68 T2 25.05.2026

This GP/LP technical episode breaks down the full circular mechanism, the role of the nearly 1,000-entity holding structure, and the tenant insolvency signals that were visible years earlier. We identify three institutional-grade red flags available before November 2023: (1) Galeria Karstadt Kaufhof’s repeated insolvencies while paying unsustainable rents, (2) the massive divergence between €27 bi...

Reza Zarrab & Halkbank 2013–2016 : How $20 Billion in Iranian Oil Money Moved Through the US Banking System Disguised as Food Purchases - EP67 T1 25.05.2026

This is the financial autopsy of one of the largest sanctions evasion cases in US history: the two-phase operation (gold exports followed by fabricated humanitarian invoices), the bribery of Turkish officials, the December 2013 corruption investigation that was politically archived, Zarrab’s arrest in Miami, and his explosive testimony that reached the highest levels of the Turkish government. We...

Reza Zarrab & Halkbank 2016 : Sovereign Compliance Gap & Correspondent Banking Risk │GP/LP Analysis - 3 Red Flag│EP67 T2 25.05.2026

This GP/LP technical episode dissects the sovereign compliance gap mechanism, how it exploited the US correspondent banking system, and the institutional risks it creates for any bank with EM relationships. We identify three critical red flags visible before Zarrab’s 2016 arrest: (1) anomalous Turkey-Iran gold export volumes, (2) the December 2013 Turkish corruption investigation and its political...

Lebanon Banking Collapse 2019 : The Banks Closed Their Doors and Kept the Money. No Law. No Court Order. Just an Informal Agreement — EP66 T1 24.05.2026

This is the financial autopsy of the Lebanon banking collapse — the sovereign-bank doom loop that turned a twenty-year institutional Ponzi scheme into one of the largest depositor expropriations of the 21st century. We dissect the full sequence: the post-civil war banking model built on dollar inflows and high-yield government bonds, the 2016 financial engineering operations led by central bank go...

Lebanon 2019 : Sovereign-Bank Doom Loop Mechanism & Circular Insolvency │ GP/LP Analysis — 3 Red Flags │ EP66 T2 24.05.2026

This GP/LP technical episode dissects the full sovereign-bank doom loop architecture: the circular dependency between BDL, commercial banks, and the government; the net negative reserve position hidden behind gross reserve numbers; the asset concentration that made bank risk identical to sovereign risk; and the interest rate structure that served as a public Ponzi signal. We contrast it with Sri L...

Sri Lanka 2022 : The Government Banned Fertilizer to Save Foreign Exchange. The Crop Failure Cost More Foreign Exchange Than the Fertilizer Did — EP65 T1 24.05.2026

This is the financial autopsy of the Sri Lanka sovereign default — the first in the country's 74-year history since independence, announced April 12, 2022. And the multi-policy collapse mechanism that converted three consecutive unforced fiscal errors into a reserve depletion spiral with no exit. We dissect the full sequence: the November 2019 tax cuts that eliminated $1.4 billion in annual re...

Sri Lanka 2022 : Multi-Policy Collapse & Sequential Option Elimination │GP/LP Analysis - 3 Red Flags│EP65 T2 24.05.2026

This GP/LP technical episode dissects the multi-policy collapse mechanism in full institutional detail: the November 2019 tax cuts and the simultaneous three-agency downgrade that closed the ISB rollover window; the reserve depletion rate through 2020-21 against the external maturity wall due in 2022-23; the fertilizer ban as a reserve proxy signal — the specific evidence that the ban was a reserv...

Mozambique Tuna Bonds 2016 : The Business Plan Said $200M Revenue. Debt Service Was $260M. The Bond Was Oversubscribed — EP64 T1 23.05.2026

This is the financial autopsy of the Mozambique Tuna Bonds — the hidden sovereign guarantee mechanism that converted a country's maritime security budget into a $2.2 billion concealed debt obligation, with Credit Suisse as active architect rather than passive intermediary. We dissect the full structure: the three state-owned entities (Ematum, Proindicus, MAM), the Privinvest contractor relatio...

Mozambique Tuna Bonds 2016 : Hidden Sovereign Guarantee Architecture & Transaction Capture │GP/LP Analysis - 3 Red Flags│EP64 T2 23.05.2026

This GP/LP technical episode dissects the hidden sovereign guarantee mechanism in full institutional detail: the three-entity structure (Ematum, Proindicus, MAM), the constitutional invalidity of the Chang guarantees under Mozambican parliamentary approval thresholds, the IMF non-concessional borrowing limits that the structure was designed to circumvent, and the fee architecture that embedded $20...

Waste Management 1998 : $1.7 Billion in Fake Profits. Arthur Andersen Found the Problem Every Year. Signed Off Anyway — EP63 T1 23.05.2026

Between 1992 and 1997, Waste Management Incorporated overstated its pre-tax earnings by $1.7 billion — the largest restatement in corporate history at the time. The mechanism was not exotic. It was a depreciation schedule. The company's management extended the useful lives of its garbage trucks, inflated their salvage values, capitalized operating expenses that should have flowed through the i...
