Tokyo’s bid to bolster the yen triggered a $35 billion intervention last week, yet the currency continued its slide, raising questions over the strategy's effectiveness.
Japanese officials stepped in on May 1 after the yen hit 160.7 against the dollar, its weakest level since July 2024. The Bank of Japan confirmed spending 5.48 trillion yen, nearly matching the 2024 record of $36.8 billion.
The yen jumped sharply from 157.8 to 155 during thin holiday trading on Wednesday, only to reverse on heavy selling. By mid-week, it traded around 156-157, erasing most gains from Tokyo’s bid to bolster the yen.
Traders spotted large yen-buying orders, but speculative shorts quickly reasserted control. Japan's top currency diplomat highlighted excessive volatility and warned against one-sided speculative positions.
Persistent U.S.-Japan interest rate differentials drove the yen lower, with U.S. yields staying elevated post-Fed pause. Higher oil prices from the Iran conflict added pressure by inflating Japan's import bill and stoking domestic inflation.
The intervention offered a brief lift but failed to shift fundamentals. Carry trades favoring the dollar remained popular, with short yen positions near multi-year highs.
Analysts noted Tokyo’s bid to bolster the yen provided tactical relief but little strategic impact. Officials reiterated readiness for further action against disorderly moves, though markets remained skeptical.
Japan's Ministry of Finance stayed silent during Golden Week holidays. The yen's resilience tested policymakers, as repeated interventions drained reserves without stemming depreciation.
Exporters gained short-term relief from the weaker yen, but importers faced mounting costs. Broader economic strain mounted from higher energy imports amid the oil rally.
The episode underscored limits to currency defense in a high-rate U.S. environment. Tokyo’s bid to bolster the yen highlighted tensions between monetary autonomy and global market forces.
