Market absolutists' complaints notwithstanding, the U.S. Treasury's plan to shore-up Fannie Mae (NYSE: FNM) and Freddie Mac (NYSE: FRE) will stabilize the bond and credit markets, but it's unlikely to sidetrack a mortgage system revision by the U.S. Congress, in one economist's interpretation.

"[U.S. Treasury Secretary Paulson has acted, now is the time for [U.S. Rep.] Barney Frank to react," economist David H. Wang told BloggingStocks Monday.

At issue: who pays for mortgage risk?

At issue is what constitutes acceptable mortgage risk by banks and mortgage lenders whose loans or asset-backed securities are insured by the U.S. Government or government service enterprises, Wang said.

"The way the system was configured, if banks and mortgage lenders made high-risk loans and won, they collected huge profits. If they made high-risk loans and lost, the government, or the taxpayer, bore the cost," Wang said. "This system is untenable."

What's one likely revision? Wang said he believes a "two-tier mortgage system will emerge." The first group will include loans/mortgages offered by banks "for specialized clients/situations." This batch of mortgages and assets tied to them would not be backed by the government or by GSE insurance, he said.

TheStreet.com's Jim Cramer says Fannie and Freddie aren't the true culprits here.

The blowhards and bluff artists and the Gang of Four -- Ambac (NYSE: ABK) (Cramer's Take), MBIA (NYSE: MBI) (Cramer's Take), MGIC (NYSE: MTG) (Cramer's Take) and PMI (NYSE: PMI) (Cramer's Take) -- truly have blood on their hands for this moment. So do the ratings agencies, the mortgage insurers and the salespeople who packaged undocumented loans and pushed buying homes with no money down.

The whole apparatus stinks and we are now seeing the unwinding, but I think that the false assurances created by the Gang of Four and their insistence to not worry made everyone way too complacent. Their glib promises as well as the incredibly lax work of the ratings agencies, S&P and Moody's, enabled the whole edifice to be propped up.

And once it was clear to them that they needed more capital, they chose to forgo the window and attack the shorts. Had they raised the capital they needed and had the ratings agencies said they can't bless any more of this junk, we might have never been in this spot.

My Ph.D. adviser David E. RePass, professor emeritus at the University of Connecticut, used to frequently recite an axiom about the U.S. Congress that rings true, regardless of era, or circumstance.

"Congress does not react, unless not reacting will result in the wrath of the American voter."

Well, concerning housing, it looks like Congress sees the wrath of the American voter ahead because the legislative body is starting to react.

Two measures working their way through Congress may ease the housing crisis. The first, a bipartisan Senate measure, is a modest step to address the rise in home foreclosures, The New York Times reported Friday.

Groucho Marx once remarked that whenever things start to look really dark, remain calm, don't panic, and above all, turn on a light.

Given the barrage of financial stresses battering the credit and equity markets these days, consumers, economists and investors alike could use some of Groucho's levity, and some light. In this case the light may appear in the form of the Federal Housing Administration.

What's old is suddenly new

The Federal Housing Administration, the once-viewed-as-antiquated, irrelevant Great Depression-era government agency, is suddenly emerging as the centerpiece of government efforts to bolster the U.S. housing market, reported The Wall Street Journal (subscription required.)

The FHA has become the cheapest, and in many cases, the only alternative for borrowers who can make only a small down payment, and the agency is rapidly gaining market share.

U.S. Treasury Secretary Henry Paulson is on the wires again, this time predicting that the number of potential home-loan defaults "will be significantly bigger" in 2008 than in 2007.

In an interview with The Wall Street Journal (subscription required), Paulson said, "The nature of the problem will be significantly bigger next year because 2006 (mortgages) had lower underwriting standards, no amortization, and no down payments. He added that "We'll watch carefully mortgages that will be reset."

Home prices fall

Paulson's comments came before the National Association of Realtors announced that home prices had fallen in 51 of 150 U.S. metropolitan areas in Q3, with the median sales price falling to $220,800 in Q3 2007, compared to $225,300 in Q3 2006. The NAR also announced that home sales fell to an annualized rate of 5.42 million units, including single-family homes and condominiums, compared to a 6.29-million-unit annualized rate a year ago.

Last March, I wrote a post which suggested that the mortgage insurance industry would take a hit as a result of the subprime mortgage meltdown. Today's New York Times [registration required] suggests that prediction was correct -- two leading mortgage insurers are writing down the value of their subprime mortgage subsidiary.

Specifically, the Mortgage Guaranty Insurance Corporation (NYSE: MGIC) said last night that it would write down its $516 million investment in Credit-Based Asset Servicing and Securitization (C-Bass) -- possibly to zero. Radian Group Inc. (NYSE: RDN) which has a $518 million stake in C-Bass, also said it might have to write off its investment completely.

Meanwhile, NovaStar Financial Group (NYSE: NFI) whose subprime mortgages MGIC insures, has fallen 91% to $10.83 from the split-adjusted $116 at which it traded in December when I suggested shorting it.
