Cooling inflation in Tokyo coupled with rising expectations of a Federal Reserve rate hike put pressure on the USD/JPY exchange rate at the 160 level.
2026-03-31 09:48:30
The USD/JPY pair continued its rebound, rising further in Asian trading after stabilizing and recovering from around 159.30 in the previous session, approaching the 160 level . This level is considered a key psychological threshold and a sensitive area for potential policy intervention. Overall, the exchange rate's rise was mainly driven by the divergence in US-Japan policy expectations and changes in inflation data.
Latest data shows a clear cooling in inflation in Tokyo, Japan. The data indicates that Tokyo's CPI rose 1.4% year-on-year in March, lower than the previous month's 1.5% , marking the lowest level since March 2022. Core CPI, excluding fresh food, was 1.7% , a slight decrease from the previous month's 1.8% , while core inflation, excluding energy and fresh food, fell to 2.3% , lower than the previous 2.5% . This series of data suggests that Japan's inflationary momentum is slowing, and market expectations for a near-term interest rate hike by the Bank of Japan have cooled significantly.
Against this backdrop, the yen weakened under pressure. As falling inflation reduced the urgency for policy tightening, the Bank of Japan is likely to maintain a relatively accommodative policy stance, thereby widening the interest rate differential with the United States. This interest rate differential has become one of the key factors driving the dollar higher against the yen.
Meanwhile, policy expectations in the United States are moving in the opposite direction. Driven by geopolitical conflicts pushing up energy prices, market concerns about a resurgence of inflation have intensified. Traders have largely ruled out the possibility of a Federal Reserve rate cut this year and are beginning to bet on the possibility of a rate hike. This shift in expectations has pushed the dollar index to a new high, further supporting the rise of the dollar against the yen.
Some analysts pointed out: "The core driver of the current market lies in the divergence of policy paths. The potential tightening expectations in the United States and the wait-and-see attitude of Japanese policy are in stark contrast, which is the key factor driving the exchange rate to continue to rise."
However, it's worth noting that Japanese authorities have clearly increased their focus on exchange rate fluctuations. Jun Mimura, Japan's Vice Minister for International Affairs at the Ministry of Finance, stated that the government is prepared to take decisive measures if excessive speculation occurs in the market. This has been interpreted by the market as a signal of potential intervention, especially as the exchange rate approaches a key psychological level.
Meanwhile, Bank of Japan Governor Kazuo Ueda also emphasized that the bank will closely monitor foreign exchange market trends and remain vigilant against rapid exchange rate fluctuations. This statement, to some extent, limited market bets on further yen depreciation, making bulls more cautious at key levels.
From a market sentiment perspective, the current trading logic is a tug-of-war between a strong dollar and the risk of policy intervention. On the one hand, widening interest rate differentials continue to drive capital inflows into dollar assets; on the other hand, potential intervention by Japanese authorities makes the market hesitant to chase the rally excessively at high levels.
From a technical perspective, on the daily chart, USD/JPY remains within an upward trend channel, with prices continuously hitting new highs. However, it is facing significant resistance near the 160 level , indicating strong psychological resistance. A decisive break above 160 in the short term could open up further upside potential, targeting higher levels; however, repeated rejections could form a temporary top. Support levels to watch are 158.50 and 157.00 . On the 4-hour chart, price momentum has slowed, and indicators show signs of overbought conditions, suggesting a potential short-term pullback. A break below 159.00 could trigger a technical correction, but the overall trend remains bullish.
Editor's Summary : Overall, the core logic behind the current upward movement of the USD/JPY exchange rate is the combination of cooling Japanese inflation, weakening expectations of interest rate hikes, and tightening US policy. However, as the exchange rate approaches a key psychological level, the risk of intervention by Japanese authorities has increased significantly, becoming a major factor limiting gains. Future trends will depend on the dynamic balance between policy signals and market sentiment. Against this backdrop, the exchange rate is more likely to maintain a high-level consolidation pattern in the short term, and investors should be wary of the risk of sharp fluctuations caused by sudden policy intervention.
