UK Rightmove House Prices MM (Aug) -2.0% (Prev. -1.0%)

Rightmove tracks asking prices rather than completed transactions, so the series measures seller sentiment at the point of listing and typically leads the lender indices and the official completed-price measures by several months. A larger month-on-month fall in August fits the established seasonal pattern: late summer listings have historically been repriced lower as sellers compete for a thinner pool of buyers, and the distinction worth drawing is between seasonal softness and a deterioration in the underlying trend, which only becomes clear once the autumn figures arrive. The transmission channel runs from asking prices into mortgage approvals and then completed-price data, with the front end of the UK rate curve reacting more to what housing momentum implies for Bank of England pricing than to the print itself. The natural follow-ons are the lender house price indices for the same month and the next round of mortgage approval and RICS survey data, which together distinguish seller caution from genuine demand weakness. Rightmove figures have historically been a secondary mover for sterling and gilts on their own, carrying more weight when they corroborate or contradict the rate path already priced.
