A firmer Japanese Yen (JPY) weighs on the Australian Dollar (AUD), leaving AUD/JPY lower at around 110.10 in early European trade on Friday. Supporting the Yen, Japan’s National Consumer Price Index (CPI) inflation has exceeded the Bank of Japan’s (BoJ) target for the first time in nine months, strengthening the argument for a widely anticipated interest rate increase in December.

Figures released by the Statistics Bureau of Japan on Friday showed that annual National CPI inflation accelerated to 2.1% in September from 1.9% in August. Core CPI, which removes volatile fresh food prices but retains fuel costs, also increased 2.1% YoY in September, up from 1.8% in August and matching the consensus estimate.
Excluding both fresh food and energy, CPI climbed 2.4% year-on-year in September, following a 2.0% increase in August. The BOJ closely monitors this measure as a better indicator of demand-led price pressures.
A Reuters poll showed that most economists anticipate unchanged rates next week, with a quarter-point increase expected at the subsequent meeting in December.
Although Standard Chartered analysts expect the BoJ to “keep the policy rate unchanged at 1.25% at its 29-30 October meeting, following September’s 25bps hike,” they emphasise that its stance will be far from neutral. Their assessment states that “we expect policy makers to maintain a clearly hawkish tone,” adding that “the debate is increasingly shifting from whether the BoJ will hike again to when the next hike will occur.” On the timing, they say, “while December is now a live meeting, January 2027 remains our base case for the next hike.” Standard Chartered also contends that “the BoJ has an incentive to continue policy normalisation to support yield differentials and reduce the risk of renewed JPY weakness, particularly if the Fed resumes tightening or maintains a restrictive policy stance for longer than expected.”
With underlying inflation approaching the 2% target and expectations continuing to climb, BoJ’s Himino has struck a distinctly more hawkish tone. His FXS Speechtracker score of 8.2/10 nevertheless matches the historic average exactly. Robust AI-related demand is boosting capital expenditure and exports, while low real interest rates and brisk bank lending further highlight how accommodative conditions are becoming increasingly at odds with the upside inflation risks outlined in the speech.
Himino’s warning that delaying policy adjustments could create inflation risks and harm the economy strengthens the case for earlier normalisation, supporting the Yen over the medium term. His emphasis on stable prices, secured through appropriate monetary policy, enhancing Japan’s sustainable growth also points to BoJ tolerance for tighter policy ahead. Near-term decisions, however, remain dependent on incoming data.
AUD/JPY’s daily chart continues to favour near-term downside, with the spot rate trading below the middle Bollinger band and considerably beneath the 100-day simple moving average (SMA). Additional overhead supply at the upper Bollinger band suggests that recoveries are likely to stall before testing the medium-term trend line represented by the 100-day SMA. At 45.43, the Relative Strength Index (14) remains slightly below neutral, signalling weak bullish momentum. This supports the view that the rebound is corrective within a wider declining phase, rather than the start of a trend reversal.
The lower Bollinger band, near 109.20, provides the first downside support, ahead of the 15 October low at 108.64. Should prices break decisively beneath that floor, the decline could extend towards 107.69, the low recorded on 13 February.
Immediate resistance sits in the 111.00-111.10 area, encompassing the psychological level and the upper Bollinger band. Closing above the latter on a daily basis could clear a path towards the 100-day SMA at 112.05. Further hurdles would then be the 16 June high of 113.55 and the 27 July high of 114.67.

Among the world’s most actively traded currencies, the Japanese Yen (JPY) broadly reflects the performance of Japan’s economy. More specific influences include Bank of Japan policy, the gap between Japanese and US bond yields, and traders’ appetite for risk, alongside other factors.
Currency control forms part of the Bank of Japan’s mandate, making its actions important for the Yen. At times, the BoJ has intervened directly in the currency market, usually with the aim of weakening the Yen. Such intervention is infrequent, however, because of political concerns among Japan’s principal trading partners. From 2013 to 2024, the BoJ’s ultra-loose monetary stance weakened the Yen against its major peers as policy increasingly diverged from that of other leading central banks. More recently, a gradual withdrawal of this ultra-loose policy has offered the currency some support.
By maintaining ultra-loose monetary policy over the past decade, the BoJ widened its policy divergence with other central banks, most notably the US Federal Reserve. This helped expand the yield gap between 10-year US and Japanese bonds, benefiting the US Dollar relative to the Japanese Yen. That gap is now narrowing as the BoJ gradually moves away from ultra-loose policy following its 2024 decision, while other major central banks cut interest rates.
Investors often regard the Japanese Yen as a safe-haven asset, turning to it during periods of market stress because of its perceived reliability and stability. Consequently, when markets turn turbulent, the Yen is likely to appreciate against currencies considered riskier investments.
