The Producer Price Index (PPI) data, released by the Bank of Japan, measures prices for goods purchased by domestic corporates in Japan. This index is somewhat correlated with the Consumer Price Index (CPI), though the correlation can vary. A higher PPI reading could lead to expectations of a Bank of Japan rate hike and support the Japanese Yen.
Data from New Zealand and Australia is less likely to impact markets upon release. The Reserve Bank of Australia is focusing on wage growth, which currently surpasses the rate of the CPI.
Asian Economic Calendar Overview
The Asian economic calendar for 13 August 2025 draws from the investingLive economic data calendar. The calendar uses GMT and shows ‘prior’ results and consensus median expectations when available.
This calendar serves as a guide for economic events influencing the market, providing key data for analysis.
We are watching tomorrow’s Producer Price Index (PPI) from Japan very closely. A high number could signal rising consumer inflation down the line, putting more pressure on the Bank of Japan (BoJ). This single data point could shift market expectations about a potential rate hike later this year.
Given that the BoJ has only hiked its policy rate once back in March 2024, the market is sensitive to any inflationary signs. With the latest July core CPI data coming in at 2.8% and the yen still weak against the dollar, hovering near 158, a strong PPI reading above the consensus forecast would be significant. We view any upside surprise as a major catalyst for JPY strength.
Derivative Trading Strategy Insights
For derivative traders, this means positioning for a potential spike in yen volatility. We are considering buying JPY call options, or USD/JPY put options, to capitalize on a sudden strengthening of the yen. The heightened uncertainty means implied volatility is already rising, so timing is critical to secure favorable pricing before the data release.
Looking at Australia, the focus remains on the persistent wage growth, which is a key concern for the Reserve Bank of Australia (RBA). Data from the June quarter confirmed the Wage Price Index grew at an annual rate of 4.1%, outpacing the latest CPI reading of 3.8%. This dynamic keeps the possibility of another RBA rate hike on the table for the coming months.
This suggests that derivative strategies favouring a stronger Australian dollar could be prudent. Traders might look at AUD/NZD call options, betting on the RBA being more hawkish than its New Zealand counterpart. We also see activity in interest rate swaps, with traders pricing in a higher probability of an RBA hike before the end of the year.
