This research assesses the probable decline of the U.S. dollar by examining economic, geopolitical, and technical variables. The research used a mixed-methods approach to investigate six hypotheses related to the U.S. debt-to-GDP ratio, geopolitical changes, economic indicators, investor confidence, bond market dynamics, and cryptocurrency integration. A quantitative study including 128 financial experts and qualitative insights from 12 interviews indicates increasing debt levels, inflationary pressures, and geopolitical challenges—especially from BRICS nations—endanger the dollar’s worldwide supremacy. The growing acceptance of digital currencies, including Bitcoin and central bank digital currencies (CBDCs), is transforming conventional financial institutions and progressively undermining the dollar. The results underscore the significance of fiscal changes, geopolitical strategy, and technological adaptability in preserving the dollar’s position as the global reserve currency. The implications for politicians, investors, and financial institutions are examined, emphasizing the critical necessity to confront these difficulties to maintain global economic stability.
