U.K. RPI y/y

The Retail Price Index (RPI) measures the change in the price of goods and services purchased by consumers for the purpose of consumption. RPI differs from Consumer Price Inflation (CPI) in that it only measures goods and services bought for the purpose of consumption by the vast majority of households and includes housing costs, which are excluded from CPI. A higher than expected reading should be taken as positive/bullish for the GBP, while a lower than expected reading should be taken as negative/bearish for the GBP.
