Washington ? It’s worrisome math: Slowing economic growth plus soaring prices could eventually equal “stagflation.”

That’s a toxic economic brew the nation hasn’t tasted in three decades.

Already, paychecks aren’t stretching as far, and jobs are harder to find, threatening to set off a vicious cycle that could make things even worse.

The economy nearly stalled in the final three months of last year and probably is barely growing or even shrinking now. That’s the “stagnation” part of the ailment. Typically, that slowdown should slow inflation as well – the second part of the diagnosis – but prices are still marching higher.

The latest worrisome news came Tuesday: a government report showing wholesale prices climbed 7.4 percent in the past year. That was the biggest annual leap since 1981.

“We’re in a slowdown,” Press Secretary Dana Perino said at the White House, where the economics talk was still upbeat until recently.

Once the twin evils of stagflation take hold, it can be hard to break the grip. People cut back on their spending as they are stung by rising prices and shriveling wages. Businesses, also socked by rising costs and declining demand from customers, clamp down on their hiring and capital investment.

That would be a nightmare scenario for Wall Street investors, businesses, politicians and most everyone else. They’re already looking to the Federal Reserve for help, but the Fed’s job is complicated by the situation.

The mission of Federal Reserve Chairman Ben Bernanke and his colleagues is to nurture economic growth and keep inflation under control. To brace the teetering economy, the Fed since September has been ratcheting down its key interest rate. Another cut is expected in March. However, to combat inflation, the Fed would be expected to boost rates instead.

“The Fed has its hands full. It is preoccupied with the economic slowdown at the front door, but inflation looks to be sneaking in the back door,” said Greg McBride, senior financial analyst at Bankrate.com. “If that trend continues, the Fed would need to show the economy some tough love, meaning higher interest rates to keep inflation from getting out of hand.”

On the other hand, Brian Bethune, economist at Global Insight, said Bernanke can fight only one war at a time, and the more pressing issue right now is to shore up the ailing economy. “That’s the war that needs to be fought. The war on inflation will have to come another day,” Bethune said.

Maybe things won’t be so bad. Stock prices rose for the day, continuing a recent mini-rally. The Dow Jones industrials closed up 114.70 points. And Federal Reserve vice chairman Donald Kohn said in a speech that he doesn’t expect the recent elevated inflation readings to persist.

“But the recent information on prices underlines the need to continue to monitor the inflation situation very carefully,” he added.

Some numbers underscore the concerns:

¢ Prices paid by consumers were up 4.1 percent last year, the biggest increase in 17 years. Those higher prices – especially for heating homes and filling up gas tanks – are taking an ever-bigger bite out of paychecks. Workers’ weekly earnings are down 1.4 percent from January a year ago when adjusted for inflation.

¢ Oil prices galloped past $100 a barrel to close at a record $100.88 on Tuesday. Those lofty energy prices are a double-edged sword: They can spread inflation through the economy by boosting the prices of lots of other goods and services, and they can leave people with less money to spend on other things, thus slowing overall economic activity. There are signs high energy prices are causing some damage on both of those fronts.
