There's a mystery facing the new Fed chair — and a false step could hurt the economy

Inflation, part of the Fed's price-stability mandate, has remained below the Fed's 2% objective throughout Chair Janet Yellen's term. Yellen has called this a "mystery."
According to Rick Reider, BlackRock's global chief investment officer of fixed income, the

nflation is being held down by secular factors including technology, which are beyond the Fed's scope.
"To try and create 2% [inflation] is actually going to hurt the economy through consumption, and particularly lower-to-middle income parts of the pocket where that inflation, particularly bad inflation, can really hurt," Rick Rieder, BlackRock's global chief investment officer of fixed income, said.

Federal Reserve Chair Janet Yellen is set to leave the helm of the central bank without hitting one of its key targets.

For five years, inflation hasn't moved above the Fed's 2% target, as measured by the year-on-year growth rate of core personal consumption expenditures. That's the Fed's preferred gauge that excludes unstable food and energy prices.

There are at least two reasons why this could be considered problematic: it hurts the credibility of the Fed's target, and reflects weak wage growth. But it's not a target that Jerome Powell, President Donald Trump's nominee for chairman, would need to be too concerned about, according to

"The world always focuses on two — it's not just the number," Rick Rieder told Business Insider. "It's the construct of inflation, and much of it is outside the scope of what the central bank can do," he told Business Insider.

Rieder added that the Fed's mandate is not 2% inflation, but price stability. That means the Fed can allow inflation to run just under 2% or even at 1% if the economy is growing, he said.

Theres a difference between good inflation and bad inflation

Fed officials expected that as more people joined the labor force, the increased demand would help lift inflation. But that relationship, characterized by the Phillip's curve, has broken down, prompting some in the Fed including Yellen to call low inflation a mystery.

They've also noted that better technology is one secular reason why inflation is low.

Cheaper cellphone service and gas are among some of the factors they consider temporary. These consumables are examples of items Rieder groups together as being part of bad inflation. People in the lowest quintiles of income distribution spend a larger share of their incomes on them, and benefit when they're cheaper.

Fed officials have said that fiscal stimulus, which includes tax cuts, represent an upside risk to the economy that could accelerate inflation. But according to
