Cryptocurrency, Macroeconomics, and U.S. Financial Hegemony

Abstract

This paper explores the intersection of cryptocurrency, macroeconomics, and U.S. financial hegemony in the emerging era of digital money. It argues that USD-backed stablecoins—such as Circle’s USD Coin (USDC) and Tether (USDT)—offer a new digital mechanism through which the United States can extend the global dominance of the U.S. dollar. Drawing from economic history, international relations theory, and decentralized finance (DeFi) innovations, the analysis situates stablecoins within a broader strategy of digital statecraft. The paper compares dollar-based crypto adoption with competing central bank digital currency (CBDC) initiatives, such as China’s digital yuan and the BRICS currency proposals, assessing their geopolitical and macroeconomic implications. Key themes include de-dollarization, programmable money, financial inclusion, and the role of digital currencies in shaping future capital flows and trade dynamics. The findings suggest that stablecoins not only replicate the traditional advantages of dollar dominance in global trade and reserves, but may also amplify them through blockchain efficiency and global reach—potentially consolidating U.S. monetary power in a multipolar world. Policy recommendations are offered for U.S. regulators to support strategic adoption of regulated stablecoins as tools of financial diplomacy and global economic leadership.
