The U.S. just recorded negative net migration for 2025—a rare occurrence not seen in over 50 years. This demographic shift raises significant questions about population dynamics and economic fundamentals. For crypto markets, such macroeconomic indicators matter because they signal broader economic trends, consumer sentiment, and capital flow patterns. When traditional economies face structural changes like population decline, investors often reassess their portfolios, which can drive interest toward alternative assets like digital currencies. Understanding these macro-level shifts helps traders contextualize market movements beyond pure on-chain metrics.
