At 21:30 Beijing time, there will be another PPI data update. This is basically the last data point to consider for the interest rate decision. The expectation is already for a 0.5% rate hike, so a poor data release simply means the rate hike has been implemented. However, if the data is positive, the market might rebound. Overall volatility is expected to be significant. Based on the CPI data, the PPI is likely to be negative as well.
