Much of that increase can be traced back to increased shipping costs during COVID lockdown.

Monetary policy isn’t the only or even the primary driver of inflation. In this case, the inflation comes from increases demand on a portion of the food supply chain (shipping services).

The alarmism in the comment section largely comes from people misreading the headline. The article is about soaring food costs in developing nations, but the comment section is treating the headline as if it’s about US food prices.

After two degrees in economics, my perception is that monetary policy is definitely considered a primary driver of inflation, probably THE primary driver. But this is probably irrelevant - see below.

Yes, for example: "in North America... a shortage of both shipping containers and truck drivers".

To me, it feels alarmist for Bloomberg to consistently say "inflation" instead of "price increases" throughout the article. A temporary problem with supply/demand is not the same as inflation. Food prices will almost certainly fall back to their normal trajectory within a year or two, once supply/demand normalizes, whereas if there was truly inflation that would almost certainly NOT occur.

To be fair, three out of the seven categories that are under inflation can also be considered "essential". Imagine the outrage if cars (or more generally, transport) and clothing increased 2x over inflation, or if cellphone/internet access became less and less affordable (remember all the "internet should be an essential service" headlines at the start of the pandemic?).

the other big correlate is just goods vs services (even textbooks are service-like due to editions). I am not an economist but I'm really curious whether rapid depreciation caused by planned obsolescence of e.g. consumer electronics is causing a poor measurement of price trends in that area. Today's iPhone will cost much less next year, but the cost of maintaining a cutting-edge smart phone keeps going up.

inflation is measuring the value of a currency. CPI is a way to infer inflation from the nominal price of consumer goods; but it is not the definition of inflation. put another way, if an apple costs twice as much as it did last year, that fact is not enough to say whether the currency inflated.

my real point here is that nominal price increases do not necessarily imply inflation. if the price of one type of good is increasing much faster than the others, a better explanation is that the real value of those specific goods is increasing. does this matter to ordinary people buying food? not really. their main concern here is the nominal price of food compared to their nominal earnings.
