USD/JPY maintained a relatively firm rangebound tone during Tuesday's Asian session, with the pair trading near 157.40 and extending its recent rebound.
The dollar remained broadly strong overall, with hawkish Federal Reserve policy expectations and rising U.S. Treasury yields continuing to support the greenback. However, the yen's depreciation has drawn sustained attention from both Japanese and U.S. officials, and as the pair moves closer to the 160 mark, the market's sensitivity to potential policy intervention has also increased.
Japanese Finance Minister Katsunobu Kato said she and U.S. Treasury Secretary Scott Bessent have strengthened communication over the yen's weakness, and she believes the yen's undervaluation is problematic. Japan's top currency official, Atsushi Mimura, previously said the market should take seriously the clear signals from both Japan and the United States regarding the yen's weakness. Japan also stressed that it will continue to maintain close communication with U.S. Treasury authorities to keep the foreign exchange market operating in an orderly manner. This series of remarks has led the market to once again raise its attention to exchange rate intervention risk.
Japan had previously stated that the basic principles followed in the coordinated Japan-U.S. intervention at the end of July remain valid, meaning that if the yen depreciates too quickly and in a disorderly manner, the scope for a policy response will remain a focus for the market.
Still, from the perspective of interest rate differentials, USD/JPY continues to have relatively strong fundamental support. The U.S. 10-year Treasury yield recently rose to its highest level since 2007, while the dollar index remained near a two-month high of about 101.2. The market currently expects the probability of another Fed rate hike in October to exceed 70%, which means the expected rate differential between the United States and Japan still favors the dollar.
The Bank of Japan had previously raised its policy rate to 1.25%, but the yen did not strengthen sustainably as a result. The market still believes that as long as U.S. yields remain high and Japan's pace of further tightening remains relatively limited, USD/JPY will find it difficult to form a trend reversal based solely on BOJ rate hikes. The core conflict for USD/JPY at present is the direct tug-of-war between the U.S. interest rate advantage and the risk of Japanese policy intervention.
Energy prices are also a variable that cannot be ignored in the recent foreign exchange market. Supply risks in the Middle East have pushed oil prices higher again, and Japan is highly dependent on energy imports. Higher energy costs will further increase the imported inflation pressure caused by yen depreciation. At the same time, rising oil prices may strengthen U.S. inflation expectations and push U.S. Treasury yields higher, thereby further supporting the dollar and creating a relatively complex two-way transmission for USD/JPY.
From the perspective of market sentiment, investors have not completely abandoned long dollar positions, but they are also unwilling to chase gains in the 157 to 160 area while ignoring policy risks. In particular, after Japanese officials repeatedly issued warnings about the yen's valuation and market order, further upside for USD/JPY at high levels may face greater volatility. Therefore, the logic for the current USD/JPY rise remains in place, but high-level policy risk is clearly increasing.
This week's U.S. economic data will become an important catalyst for the next stage of market movement. The market will focus on PCE inflation, employment data, and comments from Federal Reserve officials. If U.S. data continues to perform strongly and U.S. Treasury yields remain high, the dollar may continue to receive support; if the data cools noticeably, rate expectations may fall back and drive a technical correction in USD/JPY.
From the daily chart structure, USD/JPY recently rebounded from lows and moved back above the Bollinger middle band near 156.15, but it remains below the 100-day moving average at 159.55 and the Bollinger upper band at 159.50, indicating that the short-term rebound is still limited by medium-term technical pressure. The 14-day RSI is about 50 and has recovered from oversold territory to a neutral level, without yet showing an obvious overbought signal. The 159.50 to 159.55 area above forms dense resistance. Only an effective breakout would mean the short-term weak structure has been further repaired; otherwise, the high-level rangebound pattern may continue.
On the 4-hour chart, USD/JPY maintains a rebound structure, but the 157.50 to 158.00 area has become a short-term battleground between bulls and bears. If the price can hold above 158.00, it may further test 159.00 and the area near 159.50; if the rally is blocked and the pair falls below 156.15, short-term correction pressure will increase noticeably, with the next target potentially the Bollinger lower band near 152.85. Because the pair is already relatively close to the policy-sensitive 159.50 to 160.00 area, technical breakouts and policy risks may amplify simultaneously, and short-term volatility is expected to remain elevated.
Editor's Summary
USD/JPY is still supported by the U.S.-Japan interest rate differential and dollar strength, but continued remarks from Japanese and U.S. officials about yen depreciation have made policy intervention risk an important factor limiting further upside for the pair. Future market movement will continue to revolve around two main themes: "rising U.S. yields" and "Japanese policy intervention risk." In the short term, 156.15 is important support, 159.50 to 159.55 is the key resistance area, and 160.00 is a psychological level closely watched by the market. If U.S. economic data continue to reinforce hawkish Fed expectations, USD/JPY may still remain elevated; if yields fall back or Japanese policy signals become more hawkish, the pair may see a relatively obvious high-level pullback.
