The top US investment banks have tumbled one after the other like nine pins.Inflation which seemed like the biggest problem on the mind of the policy makers across the globe (US Fed, RBI, etc) seems to be the least of their problems at the moment.

The biggest  concern is how to rescue the globe from world wide recession. Policy makers are trying to infuse the system with liquidity so that banks and businesses can stay afloat.

Just as suddenly inflation was the word on everyone’s lips, now the policymakers are trying to deal with a bigger problem - the lingering effects of the credit crunch.

With food and energy prices soaring, central bankers on both sides of the Atlantic were making hawkish noises about inflation. "Inflation rates are expected to remain high for a rather protracted period of time before gradually declining again," European Central Bank President Jean-Claude Trichet said at a press conference Thursday after the ECB held its key rate steady at 4%. The comments came two days after Thomas Hoenig, president of the Federal Reserve Bank of Kansas City, warned in a speech of "a significant risk that higher inflation will become embedded in the economy and require significant monetary policy tightening to reduce it."

The comments, which hold the implicit threat of inflation-quelling rate increases, come at a time when worries about the financial market crisis that started last summer are on the wane. Stock and bond markets have staged a modest rebound since the Bear Stearns (BSC, Fortune 500) panic of almost two months ago, and observers including Berkshire Hathaway (BRKA, Fortune 500) chief Warren Buffett and Treasury Secretary Hank Paulson have indicated they believe the acute stage of the mortgage mess may have passed. With the prices of milk and gasoline approaching $4 a gallon in the U.S., inflation is now competing with recession as the hot-button word.

But as painful as higher prices are for consumers, there’s reason to believe that economic weakness will be the heftier burden for the economy as the year goes on. Even if financial firms avoid another crisis along the lines of the near-meltdowns earlier this year of Bear Stearns and Countrywide (CFC, Fortune 500), some economists say problems in the financial sector are only beginning to be felt on Main Street.

"The real economy hasn’t yet taken the hit," says Northern Trust economist Asha Bangalore. She says she expects unemployment, recently at 5% after falling into the low 4% range in the housing-fueled economic expansion earlier this decade, to rise to 6% before the current slowdown ends.

Bangalore points to Monday’s release of the Fed’s Senior Loan Officer Opinion survey, which showed tightening standards for all sorts of consumer and commercial loans. "The net fractions of domestic banks reporting tighter lending standards were close to, or above, historical highs for nearly all loan categories in the survey," the Fed said. That means less money is going into the economy to feed consumer spending and business expansion.

Even as lenders tighten their purse strings, Bangalore says Federal Reserve officials aren’t inclined to resume cutting rates. Instead, they want to see how the rate cuts they have already enacted - the Fed has cut its fed funds overnight lending target to 2% from 5.25% since Labor Day - affect the economy. Interest rate changes take some six to nine months to show an effect on economic growth, economists say.

"The Fed is not likely to do much in coming months," says Bangalore. "Right now, it’s a watching game."

One set of statistics everyone is watching is the numbers coming from the housing sector. Len Blum, an investment banker at Westwood Capital in New York, says he doesn’t expect to see economic growth recover until the housing sector returns to normal.

Home starts and house prices have dropped sharply in recent months, but inventories of existing houses for sale remain bloated, suggesting prices will have to fall further, he says. Executives at Fannie Mae (FNM, Fortune 500) said this week they exp
