Do small cuts in dependence sharply reduce a coalition's coercive power?
Core argument: The share of Russian financial imports controlled by the American Coalition held at a stable 94% before 2014 and fell to 84% afterward as Russia fragmented from the global financial architecture.
We show that power is nonlinear in the share of inputs controlled by the hegemon. These nonlinearities are important. To illustrate this point in the data, we focus on the economic security policies Russia instituted after its invasion of Crimea in 2014. Russian leaders anticipated the possibility of future financial coercion by the American Coalition as they further invaded Ukraine in 2022. Anticipating the possibility of future sanctions, Russia actively reduced its financial dependence on the American Coalition. Figure 8 shows that the share of Russian financial imports controlled by the American Coalition was a stable 94% before 2014 and subsequently dropped to 84% as Russia started to fragment from the global financial architecture. As a consequence, [the model implies that] the American Coalition’s financial power over Russia was approximately halved. This large loss in power is in part responsible for the muted effect of the financial sanctions that the American Coalition imposed after 2022 since Russia, via its ex-ante policies, had already prepared some alternatives
