America's prices are surging more than they have in 30 years

New York (CNN Business)There's no end in sight for higher prices. US consumer price inflation surged higher again in October, the Bureau of Labor Statistics reported Wednesday.

Over the past 12 months, prices climbed 6.2% -- the biggest increase since November 1990.

Stripping out food and energy prices, which tend to be more volatile, the index rose 4.6% over the same period, the biggest jump since August 1991.

The overall price index rose 0.9% in October alone, adjusted for seasonal swings, significantly more than the 0.6% economists had predicted, and overshadowing the somewhat more tepid 0.4% increase from September.

Excluding food and energy, prices climbed 0.6% last month -- more than in September.

Last month's price jumps came on the back of increases in multiple categories, including energy, shelter, food and cars. Food prices have risen by nearly 1% for two months in a row.

Energy costs have been going through the roof, jumping 4.8% in October and 30% over the past 12 months.

Pandemic price hikes

Rising inflation has been a hallmark of the pandemic recovery thanks to a potent mix of rampant demand, raw material shortages and choke points along the global supply chains. And the jump in energy costs is only making it worse.

America's inflation problem is likely made worse by the huge stimulus boost Washington provided to get the nation through the worst of the pandemic — which bolstered savings, household wealth and ultimately demand, according to Rick Rieder, BlackRock's chief investment officer of global fixed income.

"Further employment gains will continue to be a major driver of continued demand strength for goods and services, and higher wages will be a story that will sustain itself for many months to come," he said.
