摘要：

Current sanctions policies require that third parties such as banks and insurance companies identify and avoid engaging with violators. We focus on the global oil shipping industry to show that: (1) such identification is inherently challenging, and (2) disclosing the identities of suspected violators, instead of having third parties determine them, can reduce the profitability of violations. First, we utilize a unique dataset of tankers that actually breached sanctions on Iran in January 2021, and take the perspective of a sophisticated third party trying to detect violators using machine learning and satellite data. We find that even such an actor would have to stop doing business with a third of their clients to have a 95% chance of avoiding violators. Second, we show that when Reuters released a list of suspect tankers – alleviating identification problems for third parties – the market reacted by imposing significant penalties on these vessels. Suspect tankers saw their earnings drop by 20.5% after the disclosure, for a total loss amounting to around $781 million a year. They also began to steer clear of Russian, Iranian, or Venezuelan waters, became far more difficult to sell in the market for used tankers, and saw a 53.7% drop in their likelihood of being chartered by U.S. companies.
