Key Points
- USDJPY climbed beyond 158, marking the yen’s weakest level in a year.
- Political uncertainty and unclear BOJ timing continue to undermine the currency.
The Japanese yen weakened past 158 per dollar on Tuesday, pushing USDJPY to its highest level in a year. The move reflected rising political uncertainty in Japan, as speculation grew that Sanae Takaichi could dissolve parliament as early as next month.
Markets view the potential move as a path toward expansionary fiscal policy, with Takaichi expected to capitalise on strong public approval.
Expectations of looser fiscal settings tend to pressure the yen by increasing supply concerns and widening Japan’s policy divergence with other major economies.
Officials Step Up Verbal Warnings
Concerns over the pace of yen depreciation prompted renewed verbal intervention from Japanese officials.
Finance Minister Satsuki Katayama said she and US Treasury Secretary Scott Bessent shared concerns about the yen’s “one-sided depreciation” during a bilateral meeting held alongside a multilateral finance ministers’ gathering.
Katayama also highlighted tensions with China, citing Beijing’s export restrictions on items critical to Japan’s military, including key minerals.
These geopolitical and trade-related risks add another layer of uncertainty for the yen, even as officials attempt to slow speculative selling through rhetoric.
BOJ Policy Path Remains Unclear
On the monetary side, markets remain divided over when the Bank of Japan might deliver its next interest rate hike. Recent data releases have offered mixed signals, leaving traders without a clear anchor for policy expectations.
While the BOJ has already moved away from ultra-loose policy, the absence of firm guidance on timing or pace has limited support for the yen. As long as US yields remain elevated relative to Japanese rates, USDJPY continues to attract carry-driven flows.
Technical Analysis
USD/JPY remains firmly in an uptrend, supported consistently by the 10-day and 30-day moving averages. After weeks of consolidation just under 158, the pair has now broken higher, threatening a fresh leg upward into multi-month highs.
The trend is clearly bullish, with no major resistance in sight until the psychological 160 level.
The MACD has turned decisively bullish again, with a fresh crossover and rising histogram bars supporting renewed upside momentum.
As long as price holds above 157.50, the bulls remain in control. A daily close above 158.50 could accelerate the rally.
Near-Term Outlook Hinges on Politics and Policy
The yen remains vulnerable as long as political uncertainty and policy ambiguity persist.
Verbal warnings may slow the pace of depreciation, but without a clearer signal from the BOJ or concrete action from authorities, downside pressure is likely to linger.
In the near term, traders will watch closely for developments around parliament, further comments from finance officials, and any shift in tone from the BOJ that could alter expectations around Japan’s rate path.
