Nakamura argues that this new correlation is not merely a secondary result of U.S. Treasury yield movements but rather a reflection of Japan’s unique financial dynamics influencing global markets. Reinforcing his viewpoint, U.S. Treasury official Scott Bessent recently indicated that the domestic Treasury yields are shaped by international factors, particularly from Japan. This insight leads to a compelling notion: if U.S. economic policies are influenced by the 10-year Treasury yield, which is in turn impacted by Japan's bond markets, Japan could be playing a pivot role in shaping U.S. policy directions.
Overall, Nakamura posits that JGBs now occupy a crucial position within the global financial system, affecting a range of assets from cryptocurrencies to equities, foreign exchange, and commodities like gold. For investors, he emphasizes the importance of closely monitoring Japan’s bond market due to its potential outsized impact on global asset behaviors.
