Sure, I agree that if the trend continues for a year, then we should start being concerned.
But inflation has been below 2% since December 2018, and interest rates are at zero (which gives the Fed considerable latitude for implementing inflation control). The panic here seems a bit premature to me.
> When the economy actually reopens and people start spending again, prices will go boom.
Yes, this has actually been predicted. See also 2010-11:
> Then came a few months when inflation seemed to be rising after all. Consumer price inflation reached almost 4 percent; wholesale inflation went into double digits; the average price of commodities like oil and soybeans rose almost 40 percent in a year. Soon Republicans were haranguing Ben Bernanke, the Fed chairman, suggesting that his efforts might “debase the currency.”
> But the Fed stayed its course, arguing correctly that rising prices were a temporary blip, not a harbinger of ’70s-style stagflation. Inflation soon subsided, and it has stayed low ever since.
[…]
> So what’s going to happen in the months ahead? We’ll probably see a number of transitory price increases, not just because the economy is booming, but also because the lingering effects of the pandemic have produced some unusual disruptions — for example, a global shortage of shipping containers.
> The question will be whether these price increases are a 2010-2011-type blip or something more dangerous. Smart observers will look past the headlines to measures of underlying inflation — not just the Fed’s standard “core” measure but things like the Atlanta Fed’s sticky price index as well.
To clarify, the claim I object to is that inflation is currently, at the present moment, "running rampant." I agree that if the Fed does not handle things carefully then there may be problems in the future.
