| NEW YORK
NEW YORK A brutal year for global investors may get even worse this week if Congress proves yet again it is too bitterly divided to deliver on its promise to reduce the gaping U.S. budget deficit.
The congressional "super committee" created to slash $1.2 trillion in federal spending over 10 years was likely to concede failure in its efforts on Monday, congressional aides said.
While a breakthrough could still happen before the committee's Wednesday midnight deadline, it was considered unlikely that the group could bridge deep partisan differences over taxes and spending.
How financial markets will react to such a lack of progress is a tough call, partly because investors have been distracted by Europe's more immediate debt crisis.
For one thing, expectations could hardly be lower, especially with an election year looming and memories of this summer's ugly debate over raising the country's debt ceiling.
Also, any budget cuts would not take effect until 2013, so a failure would not trigger an immediate government shutdown or interrupt important services.
"I never expected they were going to reach an agreement and the market is clearly going to be disappointed but I think ... the market will find support at 1,200 because in the end the market really never thought they were going to do it," said Ken Polcari, managing director at ICAP Equities in New York, referring to the benchmark S&P 500 index.
"Therefore, as long as there is no news out of Europe, we will see a disappointed market but we won't implode," he said.
But a sharp sell-off in U.S. markets on Thursday afternoon was blamed in part on vague rumors that the talks to trim federal spending had stalled. After the impasse over raising the country's debt ceiling, the United States lost its triple-A credit rating, an event that is still fresh in investors' minds.
While Moody's Investors Service has said a failure by the committee to reach an agreement would not by itself lead to a rating change, Fitch Ratings has not ruled out a "negative rating action" on the United States if the economy grows less than expected or if the super committee fails to agree on at least $1.2 trillion in deficit-reduction measures.
Such an action would most likely be a revision of the U.S. rating outlook to negative from its current stable position. When Standard & Poor's downgraded the United States in August, it said at the time that U.S. fiscal plans fell short of what was necessary to stabilize debt dynamics.
"This thing is incredibly difficult to handicap," said Jacob Oubina, senior U.S. economist at RBC Capital Markets. "But the last thing you want is to introduce another element of volatility into the markets, and that's exactly what these guys are going to do because they can't get their act together."
The biggest concern is not the cuts as such but the sense that Democrats and Republicans are simply unwilling or unable to compromise and make the tough decisions required to bring a deficit that's near 10 percent of gross domestic product under control.
"There are two diametrically opposed groups here, each against what the other side is trying to do, and both see benefit to failure because they can campaign on that," said Gregory Whiteley, who helps manage $19 billion at DoubleLine Capital in Los Angeles. "So expectations are pretty low."
Clashes between Democrats and Republicans over the right mix of spending cuts and tax hikes almost scuppered a deal to lift the debt ceiling in August, raising the threat of default and spurring Standard & Poor's to cut the United States' credit rating.
THREAT TO GROWTH
Some investors do fear that deadlock may imperil White House efforts to extend a temporary payroll tax cut and jobless benefits for the long-term unemployed, and that would be another negative for growth at a time when the economy can least afford it.
RBC economists said that if those measures, along with some investment tax credits, expire at the end of this year, it could shave 1.2 percent from U.S. growth in 2012.
That could roil Wall Street stocks, which have been on a roller coaster ride since August and were on target Friday for their worst weekly showing in two months.
Stocks could lose 5 to 10 percent in the short run if anxiety about Washington policy gridlock really takes hold, said David D'Amico, president and chief strategist at Braver Capital in Boston.
"If they don't come out with anything and they force cuts and it becomes a political sideshow and the public and consumers become somewhat disgusted again with Washington, you could have a real sell-off in the marketplace," he said.
While not expected, a deal to cut the full $1.2 trillion would probably provoke a relief rally in markets, investors said.
Marc Doss, regional chief investment officer at Wells Fargo Private Bank in San Diego, said that could be a green light for hedge funds and other money managers who are underinvested in stocks because of recent market turmoil to kick off a year-end rally.
"Expectations are low after the debt ceiling debacle, but if they get to $1.2 trillion, it would instill some confidence in the political process," he said.
Bond investors say deadlock probably won't hurt the bond market, either, since Europe's problems should sustain a safe-haven bid for Treasuries.
Jack McIntyre, who helps manage a global fixed income portfolio at Philadelphia-based Brandywine Global, said that's why he remains overweight the dollar relative to the euro even as he favors currencies from faster-growing emerging markets over the greenback.
The 10-year Treasury note was yielding 2.01 percent on Friday. Among major developed markets, that was above comparable yields only in Germany and Japan.
And if stocks do wobble, another round of monetary easing from the Federal Reserve, which has toyed with the idea of pumping more money into the system by doing additional purchases of mortgage-backed debt, could help support asset prices.
LONG RUN RISKS
In the long run, though, the parallels with Europe's most troubled countries becomes more striking and harder to ignore.
Harm Bandholz, chief U.S. economist at UniCredit said America is treading a path similar to the one that led Italy, Greece and others into trouble: borrowing money at low interest rates to boost short-term growth and swelling the debt burden.
As governments in Rome, Madrid and elsewhere found out in recent days when their borrowing costs spiked to euro-era highs, that can only go on for so long. "The U.S. is still running at full speed in the wrong direction," Bandholz said.
Additionally, about 71 percent of marketable U.S. debt will mature in the next five years, said Lawrence Goodman, president of the Center for Financial Stability in New York. That's well above the historical average and makes the country vulnerable to refinancing risk.
"Markets continue to give the U.S. a pass on its excessive deficit," he said. "But what's happening in Europe should be a powerful lesson, especially given our maturity profile."
