The Australian Dollar dropped to a six-month low against the Japanese Yen on September 30, 2026. This move followed an Australian Bureau of Statistics report showing August headline inflation at 4%.
Why it matters
Lower-than-expected inflation in Australia has signaled a more dovish stance from the Reserve Bank of Australia. Meanwhile, expectations of potential interest rate hikes by the Bank of Japan have strengthened the Yen.
Australia's August headline Consumer Price Index increased by 0.4%, while the annual inflation rate climbed to 4% from 3.5% in July. Additionally, the August Trimmed Mean CPI was recorded at 3.6% year-over-year.
