British inflation rose to 3.8% in July, up from 3.6% in June, marking its highest level in 18 months and positioning the UK with the fastest rate of price increases among the world's largest advanced economies. This data highlights the ongoing inflation challenges faced by Britain compared to other major rich economies. Meanwhile, in Iran, inflation has surged to an annual rate of 64.4%, the highest since the recent conflict with Israel in June, according to economist Steve Hanke, who asserts his data as the most accurate measure of Iran's inflation.
