Inflationary pressures are building up, to judge by Morgan Stanley's latest trendspotting report, which uses grassroots research to detect supply and demand shifts often reflected in subsequent official data

Several increases relate to food and commodities, with Easter eggs shrinking in size faster than their price, for example. Reporting on data from online comparison site mysupermarket.com, Morgan Stanley says the weight of a Cadbury's giant Creme Egg has fallen 16%, with the price unchanged at Asda. The aspirational Guylian egg has fallen in weight by 14% and costs £6 (€6.80) in Sainsbury 's against £5 last year.
