The Japanese Yen weakened against the US Dollar, with the USD/JPY pair rising to near 154.55 during the early Asian session on Tuesday, as traders increased their bets on a US Federal Reserve interest rate hike in September [1]. The US Consumer Price Index (CPI) rose in August, and a key measure of underlying inflation posted its largest gains in four months, reinforcing expectations for a Fed rate hike and boosting the Greenback against the Yen [1]. Money markets on Monday indicated approximately 92.4% odds of a rate hike, up from around 60% a week ago, according to the CME FedWatch tool [1].
Lee Hardman, a senior currency analyst at MUFG, noted, "The U.S. dollar has strengthened modestly at the start of this week, encouraged by building expectations that the Fed will begin tightening monetary policy" [1]. The Bank of Japan (BoJ) is also expected to raise interest rates at its September policy meeting on Friday, with traders closely monitoring BoJ Governor Kazuo Ueda's speech for guidance on the pace and extent of future rate hikes [1]. MUFG analysts stated, "A 25 bps hike is already almost fully priced. For the yen to strengthen further, the BOJ will have to signal that they are planning to stick to the faster pace of hikes" [1].
Analysts at DBS highlighted that speculative positioning has shifted in favor of the Yen, as speculators unwound their short JPY positions following July’s joint US-Japan currency intervention and a shift in expectations towards further BoJ tightening [1]. The policy backdrop has become more supportive of normalization, with the BoJ gaining greater political room to normalize interest rates, according to DBS analysts [1].
From a technical perspective, USD/JPY maintains a bearish bias below the 100-day simple moving average, despite a modest rebound from recent lows. The Relative Strength Index (14) has recovered from oversold territory toward 36, suggesting easing downside momentum but not yet challenging the broader bearish structure. Key resistance levels are identified at 157.15 and 159.58, while support is seen near 152.25 [1].
CONCLUSION
The Japanese Yen's recent weakness is driven by rising expectations of a US Fed rate hike, while the market awaits the Bank of Japan's policy decision and guidance on future rate hikes. Speculative positioning has shifted in favor of the Yen, but further strength will depend on the BoJ's signaling of a more aggressive tightening stance. Market sentiment remains cautious ahead of key central bank meetings.
