Acommon argument among scholars and policymakers is that America's military preeminence and deep international engagement yield significant economic benefits to the United States and the rest of the world. Ostensibly, military primacy, beyond reducing security tensions, also encourages economic returns through a variety of loosely articulated causal mechanisms. A deeper analytical look reveals the causal pathways through which military primacy is most likely to yield economic returns: geoeconomic favoritism, whereby the military hegemon attracts private capital in return for providing the greatest security and safety to investors; direct geopolitical favoritism, according to which sovereign states, in return for living under the security umbrella of the military superpower, voluntarily transfer resources to help subsidize the costs of hegemony; and the public goods benefits that flow from hegemonic stability. A closer investigation of these causal mechanisms reveals little evidence that military primacy attracts private capital. The evidence for geopolitical favoritism seems more robust during periods of bipolarity than unipolarity. The evidence for public goods benefits is strongest, but military predominance plays only a supporting role in that logic. While further research is needed, the aggregate evidence suggests that the economic benefits of military hegemony have been exaggerated in policy circles. These findings have significant implications for theoretical debates about the fungibility of military power and should be considered when assessing U.S. fiscal options and grand strategy for the next decade.

Commentators and policymakers have articulated growing concerns about U.S. dependence on China and other authoritarian capitalist states as a source of credit to fund the United States' trade and budget deficits. What are the security implications of China's creditor status? If Beijing or another sovereign creditor were to flex its financial muscles, would Washington buckle? The answer can be drawn from the existing literature on economic statecraft. An appraisal of the ability of creditor states to convert their financial power into political power suggests that the power of credit has been moderately exaggerated in policy circles. To use the argot of security studies, China's financial power increases its deterrent capabilities, but it has little effect on its compellence capabilities. China can use its financial power to resist U.S. entreaties, but it cannot coerce the United States into changing its policies. Financial power works best when a concert of creditors (or debtors) can be maintained. Two case studies—the contestation over regulating sovereign wealth funds and the protection of Chinese financial investments in the United States—demonstrate the constraints on China's financial power.
