"Sweeping sanctions on the Russian banking sector should therefore precede a SWIFT ban."
Supporters of this claim argue that targeting the Russian banking sector with sanctions could have a significant impact on the country's economy and its ability to conduct international transactions. For example, a 2019 article by Anastasia Likhacheva and Anastasia Nesvetailova, titled "The Geopolitics of Financial Sanctions: Economic Statecraft and Imperialism," argues that financial sanctions on Russia have had a significant impact on the country's economy, particularly in the areas of foreign investment and access to financial markets. The authors suggest that further financial sanctions could be an effective tool for pressuring Russia to change its behavior (https://journals.sagepub.com/doi/abs/10.1177/0265691419849192).
However, critics of this claim argue that a SWIFT ban could be a more effective tool for pressuring Russia, as it would cut off the country's ability to conduct international transactions. A 2019 article by Richard Nephew, titled "Evaluating the Efficacy and Impact of US Sanctions on Russia," suggests that a SWIFT ban could be an effective tool for pressuring Russia, but also notes that such a ban would have significant impacts on the global financial system and could harm the interests of US allies (https://www.brookings.edu/research/evaluating-the-efficacy-and-impact-of-u-s-sanctions-on-russia/).
Overall, there is no clear consensus on whether sweeping sanctions on the Russian banking sector should precede a SWIFT ban. Both approaches have potential advantages and disadvantages, and their effectiveness depends on a variety of factors, including the specific goals of the sanctions, the behavior of the targeted country, and the potential impact on the global financial system.
