Bigger share of expenditures account for inflation, inflation likely widespread and not result of supply chain

Share of expenditures is the number of consumption baskets that account for 50% of inflation. Compared to the past recent months have more consumption baskets accounting for inflation. And more baskets above average inflation.

The message I would take away from these calculations is that it was plausible in the summer of 2021 to think that inflation was mainly a few price changes, perhaps due to short-term factors and supply disruptions, that would fade. But the growing number of consumption categories with substantial prices makes that interpretation less plausible. In addition, this data doesn’t take into account the more recent disruptions and price hikes associated with the Russian invasion of Ukraine and the economic sanctions that have followed.
