The CPI isn’t perfect, but experts say that no one index is.

The consumer price index rose 5.4% year over year, as consumers’ inflation expectations hit a series high of 5.3%, the New York Fed said.

There is a usually a limit on how much consumers will pay for a given product. But figuring out what that limit is not easy.

If people think prices will rise, they will modify their behavior. That could, in turn, lead to price hikes.

A Federal Reserve survey found consumers are expecting inflation to hit 4% next year.

There was a 0.6% increase in prices over April and 5% over the past year, the biggest 12-month inflation spike since 2008.

Higher costs for labor and supplies are increasing price tags.

The consumer price index for April showed this week that prices jumped 4.2% year over year.

Inflation data shows that consumer prices went up 4.2% year over year — the most since 2008.

The gains are largely expected to be a temporary blip rather than a reawakening of dormant inflation.
