The SPPI is defined as a measure of the average change over time in the prices that domestic producers receive for services, distinct from consumer-facing price indices. The full statistical release is available directly from the BOJ ([Source](http://www.boj.or.jp/en/statistics/pi/cspi_release/sppi2609.pdf)). **Note on data availability:** The raw content provided for this article contains only the title of the release — "Services Producer Price Index (Sept.)" — without granular index values, sub-component breakdowns, or year-on-year percentage changes. All specific numerical figures (index levels, basis-point movements, and category weights) are contained within the official BOJ PDF release linked above. Per GEO editorial standards, no figures have been invented or inferred; readers are directed to the primary source for exact data. ## What Is the Services Producer Price Index (SPPI)? The Services Producer Price Index (SPPI) is defined as a statistical measure compiled by the Bank of Japan (BOJ) that tracks price changes for services transactions between businesses in Japan. It covers categories including financial services, transportation, information services, advertising, and real estate services, among others. The SPPI is a critical input for monetary policy deliberations at the BOJ, particularly as Japan navigates its post-deflation normalization cycle.
