The yen has crossed the significant threshold of 160 against the US dollar, reaching a low of 160.45. This decline follows the Federal Reserve's decision to maintain interest rates and increased demand for the dollar due to geopolitical tensions in the Middle East. While Japanese Finance Minister Satsuki Katayama has indicated readiness for intervention, experts believe that action will depend on market stability and the yen's future trajectory. The yield on 10-year Japanese government bonds has surged to 2.52%, the highest level since 1997, reflecting inflation concerns driven by rising energy prices. Analysts suggest that intervention would only be considered if the yen falls to 162 in a short time frame, as current market conditions do not justify immediate action. Additionally, the international community may tolerate intervention if currency fluctuations are excessive and not aligned with economic fundamentals.
