The Coincident Index in Japan measures the current state of the economy, correlating with the business cycle. It is derived from month-over-month percentage changes in various indicators, with an increasing index generally indicating economic expansion and a decreasing index reflecting contraction. This index is used to assess economic conditions and can provide insight into overall economic health.
A higher than expected figure should be seen as positive (bullish) for the JPY while a lower than expected figure should be seen as negative (bearish) for the JPY.
