Aaron Arnold, Associate with the Project on Managing the Atom, analyzes whether or not Iran has made sufficient progress with regards to financial reform in order to see restrictions on banking lifted. He notes that while the Financial Action Task Force did not call for members to exercise countermeasures when dealing with Iranian financial institutions, he questions whether or not Iran has made moves towards to financial reform, and notes that it has not undertaken the mutual analysis efforts that other nations with financial concerns, such as Pakistan, have undertaken for more positive assessments from the FATF.

Aaron Arnold, Associate of the Project on Managing the Atom at the Belfer Center, writes in The Diplomat that a key threat to the ongoing implementation of the Iran nuclear deal is the risky nature of the Iranian financial sector. While Iran is banking on receiving greater foreign investment, continued problems with the Iranian financial sector, including lack of sufficient regulatory controls and the potential ties to terrorist financing, have made companies cautious about investing in Iran. He suggests that the United States work with Iran to bring its banking system up to the same standard as the global economy, and to consider closer integration of Iran into the world economy in order to preserve the effects of the nuclear agreement.

The Iran nuclear deal was officially implemented on Saturday, as Iran successfully fulfilled its initial key nuclear commitments and the international community relieved major sanctions, including unfreezing about $100 billion of Iranian money. Implementation Day was met with applause from deal supporters in the U.S. and Iran, while critics have raised questions about whether Iran will adhere to its requirements and how it will flex its newfound economic power. Also in recent days, the U.S. and Iran agreed to a prisoner swap that led to the freedom of Washington Post reporter Jason Rezaian and others, and negotiated the release of American sailors detained in Iran. What does the arrival of Implementation Day mean for Iran’s nuclear program and nuclear nonproliferation, and how does it bode for the future of U.S.-Iran relations? We asked Belfer Center experts to weigh in on these and related questions.

Aaron Arnold, Associate with the Project on Managing the Atom at the Belfer Center, writes in The Hill that while Iran will soon be getting sanctions relief as the nuclear accord with the P5+1 is enacted, it has not yet taken steps to update its banking system and bring it up to international money laundering and counter-terror financing. He also suggests that in order to balance the competing political and financial concerns at play with sanctions, the international community led by the United States should make clear conditions for both exclusion and rejoining of the international financial system.

Aaron Arnold, Associate with the Project on Managing the Atom at the Belfer Center, and Nikos Passas, Professor of Criminal Justice at Northeastern University, argue in The Conversation that Iran's reintegration into the global financial system may in fact make it easier, not more difficult, to monitor Iranian financial activities for illicit transactions. They point to the fact that banks can monitor transactions for entities designated as involved in terrorist or weapons of mass destruction activities by the U.S. Treasury. They also suggest that Iran may adopt stricter money laundering standards in order to increase economic integration. While challenges remain, they suggest that building a public-private partnership between banks and regulators will ensure that Iran will be caught in any illicit financial actions after the nuclear deal.

Aaron Arnold, Associate at the Belfer Center for Science and International Affairs, writes in The National Interest that contrary to what some have argued, the more Iran is connected the to global economy, the more vulnerable it is to the snapback sanctions measures built into the Iranian nuclear deal. He argues that as Iran becomes more connected to the global economy, the American dominance of financial markets and the importance of the dollar as a global currency will mean that in the event of snapback, companies will be deterred from action in Iran. As a result, the more Iran reconnects its economy to the world, the more vulnerable it will be to snapback measures.

Aaron Arnold, Associate of the Project on Managing the Atom at the Belfer Center for Science and International Affairs, writes that while Iran may receive sanctions relief as part of a final nuclear deal, it needs to take actions to strengthen its financial laws and regulations in order for it to truly be integrated into the global economy. He argues that Iranian financial laws, specifically those relating to money-laundering, terrorism financing, and proliferation financing, remain weak and do not meet the standard of the international financial community. These legal weaknesses have caused Iran to remain designated by the U.S. Treasury as a "jurisdiction of primary money-laundering concern," making it much harder for the Iranian financial sector to operate using American currency or the American financial system, which, despite recent developments such as the launch of the Asian Infrastructure Investment Bank, maintains the dominant role in global finance. He concludes that without these reforms to Iran's banking sector, its benefits from the ending of sanctions will be much smaller than desired by Iranian policymakers.

Aaron Arnold, Associate with the Project on Managing the Atom at the Belfer Center, and Nikos Passas, Professor of Criminal Justice at Northeastern University, argue in The Bulletin of the Atomic Scientists that an important, and generally overlooked, aspect of any deal with Iran is the role of banks and financial institutions in monitoring proliferation related transactions and keeping Iran from cheating on the agreement. They point out that banks are necessary for the monitoring and verification of a nuclear agreement because they provide the information used by sanctions enforcers to track illicit proliferation financing. At this point, several holes exist in detecting proliferation financing, including the lack of a clear template for banks and regulatory agencies to be searching for, and the lack of binding regulations for all forms of financial institutions, such as money remitters. They suggest that the Iranian nuclear deal offers a chance for these systematic holes to be plugged by centralizing analysis of data for proliferation financing and seeking reforms in the Iranian financial system.

Aaron Arnold, Research Associate with the Program on Managing the Atom at the Belfer Center, writes in the Bulletin of Atomic Scientists that U.S. lawmakers advocating a continuation and strengthening of the sanctions program against Iran are operating on a series of misperceptions and myths about sanctions. Specifically, he argues that the United States cannot operate under the belief that international partners will automatically a continuation of sanctions, that snap-back sanctions will not be effective in hurting the Iranian economy in the event of a violation of the terms of a nuclear deal, and that the United States will continue to dominate the international financial system. This myths are out of sync with international realities, and domestic politics needs to catch up to this fact, he concludes.

Aaron Arnold provides a crucial update on the status of the economic sanctions placed on Iran. He argues that in the short term, a lack of sanctions relief will continue to damage the Iranian economy and undercut efforts by the Rouhani Administration to revitalize growth. However, he points out that new developments in the global economy, such as the creation of an alternative to the SWIFT financial messaging system pushed by Russia and China, will possibly degrade the effectiveness of sanctions in the long run.
