This Anti-Corruption Helpdesk brief was produced in response to a query from a U4 Partner Agency. The U4 Helpdesk is operated by Transparency International in collaboration with the U4 Anti-Corruption Resource Centre based at the Chr. Michelsen Institute.
Query
What evidence exists on corruption risks linked to exchange rate distortions and foreign currency allocation systems? What mechanisms have been documented in Lebanon, Nigeria, Syria and Venezuela? Finally, how do these risks affect aid funded and humanitarian programming?
Summary
Foreign exchange controls and the proliferation of exchange rate systems can create opportunities for corruption where access to scarce or preferential foreign currencies is discretionary and opaque. Documented risks include bribery, preferential allocation, trade misinvoicing, embezzlement, money laundering and the capture of parallel currency markets. These risks can also affect aid funded and humanitarian programmes by reducing the real value of assistance and creating opportunities for diversion and fraud in procurement, cash programming and financial reporting. Several measures can help organisations manage these risks, but evidence on their effectiveness remains limited.
Main points
- Exchange rate differentials can create substantial economic rents, but they are not in themselves evidence of corruption.
- Corruption risks are greatest where access to scarce or preferential foreign currency combines economically valuable rents with discretion over allocation and limited transparency or oversight.
- Country evidence from Lebanon, Nigeria, Syria and Venezuela documents several mechanisms through which foreign exchange systems can become exposed to abuse. These include bribery for preferential allocation, shell entity capture, trade misinvoicing, institutional conflicts of interest, state capture of aid conversion and money laundering, although the strength of evidence varies considerably across countries.
- Exchange rate distortions can also affect aid funded and humanitarian programming. Risks arise at different points in the funding chain, including procurement, cash and voucher assistance, financial service provision, currency conversion and financial reporting, where opaque rates, fees or conversion arrangements can reduce the effective value of assistance and make diversion or fraud harder to detect.
- Unofficial or unregulated exchange channels are not inherently corrupt and may be necessary where formal financial systems are inaccessible. However, where transactions leave inadequate records of the amount converted, exchange rate applied or fees charged, donors and implementing organisations may find it difficult to distinguish legitimate exchange rate losses and transaction costs from
manipulation or diversion. - Available evidence suggests that financial and operational risks in humanitarian partnerships can fall unevenly on international organisations, local partners and aid recipients. However, this review identified little comparative evidence establishing who ultimately bears exchange rate related integrity risks or whether particular groups, including local
organisations, women or financially excluded recipients, are disproportionately affected. - Humanitarian actors use or have considered measures including preferential humanitarian exchange rates, diversification of conversion providers, digital delivery, financial audit and third party monitoring, rate benchmarking and centralised currency management. Evidence of their effectiveness is limited, and each can introduce trade-offs related to access, compliance costs, financial exclusion, legal or security risks and the distribution of exchange rate losses.
