Data will be available in the following section of the Bank's website at around 2:00 p.m. on August 15, 2016:

The 2015-base data of other indicators (trimmed mean, diffusion index of increasing/decreasing items, mode, and weighted median) for the January-June 2016 period will be published with the July data to be released on August 31, 2016, three business days after the release of the official CPI data for July 2016.
