This past week has been notable for the Japanese yen, which saw a significant increase marking the biggest weekly rise in a year. The yen closed the week at 153.08 against the US dollar, despite a slight drop of 0.15% on the last day, ending with a 2.64% increase, the highest performance since February of the previous year. Against the euro, the yen remained relatively stable at 181.41, with a weekly gain of 2.27%, also the largest in a year.

Market dynamics were influenced by the lesser-than-expected inflation increase in the United States, which showed a 0.2% rise in consumer prices for January against predictions of a 0.3% increase. This less inflationary pressure has led to speculations that the Federal Reserve might keep interest rates stable in the short term, which has had minimal impact on the dollar's performance. Consequently, the euro softened slightly against the US currency by 0.07%.

The context behind the yen’s rise is deeply tied to domestic politics, particularly the recent electoral victory of Prime Minister Sanae Takaiichi, which has amplified investor confidence in Japan’s economic policies and sustainability. As Japan continues to navigate its economic recovery and potential interest rate adjustments, the yen's performance will be closely monitored in light of both domestic and international economic indicators, reflecting broader trends in currency stability and financial market reactions.
