Why Inflation Doesn't Explain Nominal Sales

US September retail sales data were old news, but slightly softer. While it is tempting to blame the accelerating US inflation rate, retail sales are nominal numbers and include inflation effects. Pessimism should be limited, however. The numbers will almost certainly be revised. Ongoing shifts in consumption patterns have consequences (Instagrammers showcasing their latest holiday contribute less to retail sales than buyers of new washing machines). Credit card data suggests no reason to panic.
