When Hawala Meets Dìxià Qiánzhuāng: Trade-Based Settlement and Cross-Ethnic Trust in European Criminal Finance

AbstractResearch on informal value transfer systems has generally treated Chinese underground banking (dìxiàqiánzhuāng) and hawala as separate, culturally bounded phenomena. This paper argues that such a framing mayno longer hold — at least not in Europe. Drawing on three recent law-enforcement operations (Italy 2023, Spain2025, France–Spain 2024), this paper argues that hawala networks and Chinese brokers are not running parallelsystems but operating a functional division of labour: hawala operators aggregate criminal cash at the retail level,while Chinese money-laundering networks clear the resulting obligations wholesale through trade-basedsettlement.To explain why this convergence is possible and how it is sustained, we develop a Settlement Arbitrage Modelgrounded in Transaction Cost Economics (Williamson 1985) and the economic theory of clubs (Buchanan 1965;Schramm and Taube 2003). The model proposes that Chinese brokers undercut rival laundering providers bycross-subsidizing their fees with arbitrage income from two commodity corridors: European luxury goodsshipped to China via daigou networks, and low-cost manufactures exported from Yiwu to Africa, the Middle East,and Latin America. Value transfer occurs through duìqiāo (ledger offsetting) rather than physical currencymovement — a claim consistent with the complete absence of RMB (PR China currency) banknote seizures in theEuropean enforcement record. Cross-ethnic cooperation appears to rest not on shared cultural identity but oncommercially verified, iterated performance: what we call "professional trust."
