Japan's Finance Minister Satsuki Katayama issued a verbal warning on Friday, stating that Japanese authorities are prepared to take decisive steps on foreign exchange if necessary, referencing the US Treasury's forex report and emphasizing ongoing communication with US counterparts. Katayama declined to discuss specific currency levels but reiterated readiness to act appropriately on currency shifts whenever required [1]. This follows a similar warning from Katayama earlier in the week, where she stated that Japan's policy on potential intervention remains unchanged and that authorities would take 'appropriate and bold action' if needed [2].
On the same day, Japan's Statistics Bureau reported that National Consumer Price Index (CPI) inflation rose to 1.7% year-on-year in June, up from 1.5% in May. Core CPI increased to 1.6% year-on-year from 1.4%, marking the first rise in core inflation since March and aligning with market expectations. However, the 'core-core' inflation rate, which excludes fresh food and energy, fell to 1.7% year-on-year, the lowest since August 2022 [2].
Despite the inflation data, the Japanese Yen remained near a multi-decade low against the US Dollar, with the USD/JPY pair trading at 163.83–163.90 during the Asian session on Friday [1][2]. The market reaction was muted, with USD/JPY down just 0.02% on the day at 163.83 [1]. According to [2], the CPI report had little to no impact on the Yen, as traders are focused on the possibility of intervention by Japanese authorities ahead of the upcoming Bank of Japan policy meeting, where the central bank is widely expected to leave interest rates unchanged.
Additionally, [2] notes that escalating tensions in the Middle East could further strengthen the US Dollar against the Yen in the near term, citing a Reuters report on US President Donald Trump's warnings to Iran and the Houthis. However, no direct market impact from these geopolitical developments was reported in the articles.
CONCLUSION
Japanese authorities have reiterated their readiness to intervene in currency markets as the Yen remains near multi-decade lows, despite a modest rise in inflation. Market participants appear to be awaiting potential intervention or signals from the upcoming Bank of Japan meeting, with little immediate reaction to the latest CPI data. The situation remains fluid, with official statements and geopolitical developments closely watched by traders.
