Jobs are coming back, wages are rising, stock markets are hitting record highs. In many ways, the US economy is booming. And yet as we officially enter the holiday season, consumer confidence is at its lowest level in a decade. The reason? Inflation.

The US inflation rate in October was the highest it has been since the early 90s, when Nirvana released Smells Like Teen Spirit and the Gulf war was just beginning.

But should we really be worried? The Federal Reserve, and the Biden administration, think rising prices are “transitory” – caused by the hangover from the pandemic. Their critics are less sure.

Inflation, especially during a global pandemic, is complicated. Here is what we know about inflation in the US.

What is inflation?

Inflation describes a general rise in the level of prices of all consumer goods and services. It is not specific to a particular good or service; rather it is a measure of when, broadly, things are more expensive than they were before.

There are a handful of ways inflation is measured, though the Consumer Price Index (CPI) measured by the US Bureau of Labor Statistics is the most common system used to gauge inflation. The index looks at the prices of goods and services in cities and suburbs across the country, weighted depending on the proportion a good or service has in overall consumption. For example, food and housing is weighted more than clothing in the index.

What’s happening with inflation?

According to CPI numbers released in mid-November, prices in the US rose 6.2% in October compared with where prices were the same time last year. US core inflation, which does not include goods like energy and food whose supply is susceptible to external events, was 4.6% in October, its highest since 1991.

Prices broadly increased in energy, housing, food, used and new vehicles and recreation. Price decreases for airline fares and alcoholic beverages were among the few price declines seen last month.

The US is not the only country experiencing inflation – the UK, China and Germany have all also reported rising inflation in the last few weeks.

The Fed has already taken steps to reduce inflation, ending some of its stimulus programs that saw it buying bonds to stimulate the economy. But the central bank has held off on its main tool to control inflation – adjusting interest rates – probably because doing so runs a higher risk of starting an economic recession.

How worried should Americans be about inflation?

Some economists have been pointing out that the inflation we are seeing now is just one piece of the pandemic’s impact on the economy, which overall has not been terrible.
