This book came out earlier this year at what turned out to be precisely the right moment. The financial sanctions against Russia for its February 2022 invasion of Ukraine were unprecedented in their size and scope, but, as this book points out, financial sanctions had become an increasingly common tool of the U.S. government, one which both relied on the dominance of the U.S. dollar in the international economy and that at the same time threatened that dominance. Everyone from John Kerry to Jack Lew recognized that financial sanctions, although necessary at times, could erode the dollar's position, and, as the author points out, in some cases their concerns were justified.
The author is not a dollar doomsayer, as many writers on the subject are, but he does point out some notable instances in which the threat of financial sanctions causes countries to move away from the dollar. The number of sanctions-related executive orders has gone from 22 in 2000 to 94 in 2020, and the number of states targeted under an Office of Foreign Assets Control program went from 4 to 21. The 2011 freezing of $37 billion in Libyan assets during the civil war there was a pivot point and made many countries aware that the U.S. could becloud their finances at the stroke of a pin. Starting in 2017 Turkey increased its holdings of tons of gold by 300% and it dropped most of its holdings of U.S. Treasuries. Although Russia began moving some of its reserves out of the US after the 2014 sanctions against it's Crimean invasion, it was really after a new round of sanctions in 2018 that they built up domestic gold holdings and shifted to the Euro. (Although, admittedly, when the Europeans sanctioned Russia in 2022, that did not help it.) And while 30% of its reserves were still in dollar holdings before the war, just 10% of those were in the US itself, which allowed Russia to move money around more.
The author shows that, beyond reserves, countries under sanctions or threat of sanctions have had some success moving invoicing and exports and imports out of dollars (especially Russia with its increased invoicing in Euros) mostly the dollar has continued to dominate trade, even among sanctioned countries. On the whole, the author shows that while countries respond to the threat of sanctions, the power of the dollar is so strong that if anything it has increased its global dominance during the rise of financial sanctions. This book is an important reminder of the importance of that fact, and also that it is not inevitable.
