Claims that the worst of the financial crisis is over have been rubbished by ex-IMF Chief Economist , who yesterday warned that a major U.S. bank is likely to collapse within months.

Money Morning’s William Patalon III says dire warnings like this are becoming more frequent. And the slump in shares for Fannie Mae (FNM) and Freddie Mac (FRE) this week is generating more fear among investors.

William says the financial meltdown will keep the Fed from raising interest rates anytime soon. But at a time when inflation is accelerating, this will create more problems down the line…

The global financial crisis is set to get much worse, with a large U.S. bank failure likely in the next few months, former International Monetary Fund (IMF) Chief Economist Kenneth Rogoff has warned.

Speaking at a conference in Singapore, Rogoff, now an economics professor at Harvard University, said that despite hopes that the U.S. economy had turned the corner, the reality is that “the worst is to come.” And that includes the probable collapse of a “whopper” U.S. bank or investment bank, he said.

“We’re not just going to see mid-sized banks go under in the next few months,” said Rogoff, who held the IMF role between 2001 and 2004. “We’re going to see a whopper, we’re going to see a [failure of a] big one – one of the big investment banks or big banks.”

Rogoff’s comments – reported by Great Britain’s BBC News – coincide with Money Morning’s repeated predictions over the past year that the ongoing U.S. financial crisis would have real staying power. Just this week, in fact, Money Morning featured an exclusive interview with investing guru Jim Rogers, in which the well-known author and commentator said that Americans will be feeling the fallout from this crisis for years to come.

The end of this global financial crisis “is a long way away,” Rogers said. “In fact, it may not be in our lifetimes.”

Dire predictions like those made by Rogoff have been increasing in frequency. Back in June, analysts with the Royal Bank of Scotland Group PLC (ADR: RBS) warned clients to brace for a full-blown crash in the global stock-and-bond markets that would take place within 90 days, as the conflicting realities of slowing growth and rising inflation paralyzed the world’s major central banks. The result: “All the chickens will come home to roost,” the RBS analysts told Great Britain’s Daily Telegraph newspaper.

That report raced across the Internet, although it appeared at the time that European news organizations gave it much greater play than their U.S. counterparts.

The Fed’s Market Missteps

This week’s comments by Rogoff, the former IMF official, came as shares of Fannie Mae (FNM) and Freddie Mac (FRE) sank Monday on a report that the Bush administration wants to nationalize the two mortgage lenders.

In his speech in Singapore, Rogoff predicted that Fannie Mae and Freddie Mac would “probably” not exist in their present form in just a few short years, stating that “we have to see more consolidation in the financial sector before this is over.”

On Monday, shares of Fannie Mae fell more than 22%, or $1.76, to close at $6.15. Shares of Freddie Mac fell almost 25%, or $1.46, to $4.39. Fannie Mae’s shares were down another 1.63% yesterday (Tuesday), closing at $6.05, and Freddie Mac’s shares dropped by another 5.74%.

Shares in Freddie and Fannie plunged in July on investor fears that the two government-sponsored enterprises would run out of money to fund their businesses, which prompted the U.S. government to step in and take radical steps to avert a financial panic.

As mortgage guarantors that are there to pay up when homeowners default on their loans, the two firms have served as the financial backbone of the U.S. mortgage market: Virtually all U.S. mortgage lenders rely on the two to buy up mortgages in order to access the funds to lend to consumers.

With the onset of the subprime mortgage crisis – and the one-two punch of collapsing home values and soaring foreclosures – Fannie and Freddie’s finances have been savaged. That subprime crisis and ensuing global financial crisis has hammered the global credit markets and led U.S. Federal Reserve policymakers to slash the benchmark Federal Funds rate from 5.25% last September all the way down to 2% earlier this year.

But Rogoff has joined the growing list of critics who maintain that it was a major miscue for the U.S. central bank to cut interest rates as “dramatically” as it did. The reason: Cutting interest rates “is going to lead to a lot of inflation in the next few years in the United States,” Rogoff said.

But inflation may still not be the top worry over at the Fed.

On Friday, two top central bank officials predicted a weak second half for the U.S. economy, warning that strong U.S. growth may not return until 2010. Atlanta Federal Reserve Bank President Dennis P. Lockhart and Chicago Fed Bank President Charles L. Evans both said the U.S. central bank is in no hurry to start raising rates while the American economy is sputtering badly because of an ongoing global financial crisis, a sagging housing market and inflationary pressures caused by a yearlong run-up in food-and-energy prices.

In fact, Lockhart even said he wouldn’t rule out actually cutting interest rates if economic circumstances warranted – a remarkable admission at a time when the economic crisis is juxtaposed over rising inflationary pressures, and when most Fed-watchers expect the central bank’s next move to be an increase in interest rates.

A reduction in interest rates would jump-start U.S. growth. But there’s a good chance it would also re-start an escalation in energy and food prices – and a resumption of the bull market in overall commodity prices. Coupled with the ongoing downward spiral in the U.S. housing market, this could signal the return of stagflation for the first time since the 1970s.

There’s evidence this is already happening. Wholesale prices advanced at their steepest annual rate in 27 years last month, while monthly housing starts dropped to their lowest level in 17 years, two separate government reports said yesterday.

In fact, the 1.2% monthly increase in wholesale prices was well above what economists had been anticipating. For the 12 months through July, wholesale prices advanced at a 9.8% annual clip. Prices haven’t increased that steeply since the deep recession of the early 1980s.

But there may be two opposing schools of thought forming inside the Federal Reserve. Federal Reserve Bank of Richmond President Jeffrey M. Lacker feels the policymaking Federal Open Market Committee (FOMC) might have to boost interest rates before signs of an economic recovery are actually confirmed, Bloomberg News reported yesterday (Tuesday).

“It is important to withdraw this monetary policy stimulus in a timely way,” Lacker said in a Bloomberg Television interview. “That may require us to withdraw before we are certain all of the weakness is behind us and before we are completely certain that financial markets are as tranquil as we would like to see.”

Central bank policymakers signaled two weeks ago that the U.S. financial crisis and the souring employment outlook would delay any increase in short-term interest rates. And those officials – including Lacker – ruled out any potential for rate reductions.

“I certainly don’t think the Federal Funds rate should be any lower, given where we are now,” Lacker said. `Monetary policy is very stimulative right now [and] we are still in a fairly risky situation” on the inflation front.

One last point is worth noting: While Lacker is a voting member of the FOMC, Evans and Lockhart don’t attain that authority until next year.
