Japan's persistent low bond yields, despite its massive government debt, are raising concerns of a potential currency crisis. The Financial Times highlights that Japan's new Prime Minister, Asomi Nakatomi, has announced a fiscal stimulus plan that continues the risky perception that high debt levels are manageable. The Bank of Japan's previous strategies, including large-scale bond purchases and yield curve control, have kept interest rates artificially low. However, global inflation and rising interest rates have challenged this approach, potentially leading to a dangerous cycle of currency depreciation if Japan continues its rate suppression policies.
