Japan's opposition party leader recently raised concerns about market volatility, warning that authorities need to take stronger action against sharp fluctuations in the bond market. His comments come as Japanese government bonds experienced a significant selloff that rattled global financial markets. The rapid decline in JGB prices has created ripple effects across international markets, prompting calls for more decisive intervention. Observers are watching closely to see if Tokyo will implement measures to stabilize the fixed-income sector and prevent further contagion to global risk assets.
