Stronger Japanese GDP and Wage Growth Firm BoJ Rate Hike Expectations
Japan’s revised Q2 GDP growth came in at 0.4% quarter-on-quarter, up from the initial 0.3%, with annualized growth raised from 1.1% to 1.4%. Capital expenditures declined less sharply at 0.9%. While private consumption was flat, overall economic performance strengthened arguments against delaying monetary normalization. July’s nominal cash earnings growth was revised sharply higher to 4.7% year-on-year—the fastest pace since 1997—well surpassing forecasts. This broadly representative wage data reduces concerns about seasonal bonus distortions and supports the case for Bank of Japan (BoJ) tightening. Market pricing quickly adjusted, with near-certain odds (98%) of a September hike to 1.25%, January 2025 hike to 1.50% largely factored in, and an expectation of approximately 3.7 total hikes before July 2027. Attention now turns to the pace of further tightening.
Policy Makers Signal Steady BoJ Tightening Through Early 2027
Koji Aida, key economic advisor to Prime Minister and a member of the government’s economic committee, expressed expectations for the BoJ to start hiking rates in September and maintain a roughly quarterly pace until softening the cycle in early 2027. This represents an acceleration from his prior forecast targeting the initial hike in January 2027, indicating fewer obstacles to policy normalization. Nevertheless, the market remains attentive to demand-side indicators such as household consumption to assess tightening’s economic impact.
Australian Economy Weakens, Pressuring AUD/JPY
In Australia, the NAB business conditions index for August slumped from +4 to -1, its first negative reading in six years. The profit index fell sharply to -9, affected by a 2.3% month-on-month rise in input costs outpacing a 0.8% rise in product prices. Trading conditions deteriorated despite steady employment. Consumer sentiment also declined, with the September Westpac-Melbourne Institute consumer confidence index dropping 5.2%. Notably, 64% of consumers expect mortgage rates to increase over the next year, reflecting concern about rising borrowing costs. While Westpac highlights existing risks, it anticipates the Reserve Bank of Australia (RBA) will hold rates steady at the late September meeting, citing inflation data insufficient to justify immediate hikes. The hawkish tightening agenda faces challenges from weakening domestic demand and profit pressures.
AUD/JPY Poised Near Key Technical Support
AUD/JPY fell sharply from a high of 114.95 and currently tests critical support at 109.25. Technical indicators show bearish divergence, implying risk of further declines toward the 38.2% Fibonacci retracement level near 103.90 if 109.25 breaks decisively. However, the RSI indicates oversold conditions, suggesting a potential technical rebound in the short term. The downtrend remains intact as long as resistance around 112.78 is not overcome.
NZD/JPY Drops Amid Skepticism on RBNZ Rate Path
NZD/JPY’s decline reflects different dynamics. Despite the Reserve Bank of New Zealand’s (RBNZ) back-to-back rate hikes, market confidence in further tightening has not risen materially. The pair broke below key support at 91.02, with targets shifting down to 89.44 and 85.76. Technical signals reveal bearish divergence similar to AUD/JPY. Short-term oversold bounce opportunities exist, but the dominant momentum remains downward.
Yen’s Yield Advantage Emerges as a Driving Factor
The primary driver behind both currency pairs is a strengthening yen supported by expectations for BoJ tightening. AUD/JPY reflects Japan’s anticipated rate hikes contrasting with Australia’s slowing economy, while NZD/JPY’s steeper decline underscores doubts about the sustainability of New Zealand’s tightening cycle. This dynamic challenges previous assumptions that other major central bank currencies enjoyed more credible tightening trajectories relative to the yen.
The upcoming BoJ policy meeting on September 17–18 will be crucial in confirming these macroeconomic trends and market expectations. Forex market focus will remain on the durability of Japanese wage and economic data supporting a tightening cycle and the divergent rate paths between Australia and New Zealand shaping asset price movements.
