Economic crime has evolved from opportunistic fraud into coordinated, state-sponsored networks that deliberately exploit the blind spots of global finance. For commodity trading groups, shadow fleets evade sanctions through ship-to-ship transfers and flag changes invisible to standard counterparty screening, while trade-based money laundering moves billions through pricing manipulation that payment-level monitoring cannot detect. For global commercial banks, the same actors exploit correspondent banking networks to layer illicit funds across jurisdictions, construct beneficial ownership structures that defeat standard KYC, and conceal criminal flows within the sheer volume of legitimate transactions. For security services, the financial networks funding hostile states, proliferation programmes, and organised crime are increasingly indistinguishable from legitimate commercial activity — threading through the same commodity trades, the same correspondent banking channels, and the same encrypted communications platforms that markets depend on. Market abuse operates across all three through trading communications that keyword-based surveillance cannot parse. The threat is systemic, adaptive, and state-sponsored. The response has not kept pace.
