In the long run, the devastation the storm inflicted on New York City and other parts of the Northeast will barely nick the U.S. economy. That's the view of economists who say a slightly slower economy in coming weeks will likely be matched by reconstruction and repairs that will contribute to growth over time.
The short-term blow to the economy, though, could subtract about 0.6 percentage point from U.S. economic growth in the October-December quarter, IHS says. Retailers, airlines and home construction firms will likely lose some business.
The storm cut power to about 7 million homes, shut down 70 per cent of East Coast oil refineries and inflicted worse-than-expected damage in the New York metro area. That area produces about 10 per cent of U.S. economic output.
New York City was all but closed off by car, train and air. The superstorm overflowed the city's waterfront, flooded the financial district and subway tunnels and cut power to hundreds of thousands. Power is expected to be fully restored in Manhattan and Brooklyn within four days.
Most homeowners who suffered losses from flooding won't be able to benefit from their insurance policies. Standard homeowner policies don't cover flood damage, and few homeowners have flood insurance.
But Fannie Mae and Freddie Mac said they will offer help to borrowers whose homes were damaged or destroyed, who live in designated disaster areas and whose loans the mortgage giants own or guarantee. Among other options, mortgage servicers will be allowed to reduce the monthly payments of affected homeowners or require no payments from them temporarily.
Across U.S. industries, disruptions will slow the economy temporarily. Some restaurants and stores will draw fewer customers. Factories may shut down or hold shorter shifts because of a short-term drop in customer demand.
Some of those losses won't be easily made up. Restaurants that lose two or three days of business, for example, won't necessarily experience a rebound later. And money spent to repair a home may lead to less spending elsewhere.
With some roads in the Northeast impassable after the storm, drivers won't be filling up as much. That will slow demand for gasoline. Pump prices, which had been declining before the storm, will likely keep slipping. The national average for a gallon of regular fell by about a penny Tuesday, to $3.53 — more than 11 cents lower than a week ago.
Shipping and business travel has been suspended in areas of the Northeast. More than 15,000 flights across the Northeast and the world have been grounded, and it will take days for some passengers to get where they're going.
On Tuesday, more than 6,000 flights were cancelled, according to the flight-tracking service FlightAware. More than 500 flights scheduled for Wednesday were also cancelled.
The three big New York airports were closed Tuesday by the Port Authority of New York and New Jersey. New York has the nation's busiest airspace, so cancellations there drastically affect travel in other cities.
Economists noted that the hit to the economy in the short run was worsened by the size of the population centres the storm hit.
"Sandy hit a high-population-density area with a lot of expensive homes," said Beata Caranci, deputy chief economist at TD Bank.
Hurricane damage to homes, businesses and roads reduces U.S. wealth. But it doesn't subtract from the government's calculation of economic activity.
By contrast, rebuilding and restocking by businesses and consumers add to the nation's gross domestic product — the broadest gauge of economic production. GDP measures all goods and services produced in the United States.
Paul Ashworth, chief U.S. economist at Capital Economics, expects the storm to shave 0.1 to 0.2 percentage point from annual economic growth in the October-December quarter. He thinks the economy will grow at an annual rate of 1.5 per cent to 2 per cent in the fourth quarter. It expanded at a 2 per cent annual rate last quarter.
But Ashworth says any losses this quarter should be made up later as rebuilding boosts sales at building supply stores and other companies.
"People will load up on whatever they need to make repairs — roofing, dry wall, carpeting — to deal with the damage," he says.
In the short run, Caranci said the economic damage could be heaviest for small businesses that lack the money and other resources to withstand lost sales.
"It will remain to be seen how long disruptions to electricity and infrastructure persist," she said.
But she noted that the storm should give a boost to the construction industry, which shed millions of workers after the housing bust. Many who lost construction jobs were skilled employees with disproportionately high pay, and the loss of those jobs hit the economy hard.
Major retailers began trying Tuesday to ramp up their operations before the critical holiday shopping period.
Sears Holdings Corp., which operates Kmart and Sears, said 80 of its stores were still closed as of midday Tuesday, down from 187 Monday. Wal-Mart Stores Inc., the world's biggest retailer, said it was working to reopen the 168 stores it closed. And Darden Restaurants Inc., parent company of Olive Garden and Red Lobster, by Tuesday afternoon had reopened roughly 160 of the 260 restaurants it closed Monday.
Retailers collect up to 40 per cent of their annual revenue in November and December. Retailers, excluding restaurants, could lose at least $25 billion in sales this week, estimates Burt Flickinger III of retail consultancy Strategic Resource Group. Because of the storm, he's reduced his forecast for holiday sales to a 2.1 per cent increase over last year from the 3.2 per cent increase he had predicted earlier.
Reopening is often difficult after a storm. New York City's subways and buses remained closed Tuesday, making it hard for employees to get to work. Macy's and Saks Fifth Avenue flagship stores stayed closed Tuesday — bad news for those retailers, because major department stores can derive 10 per cent of annual sales from their Manhattan locations.
Still, those stores that could open for business did. A Westside Market in Manhattan remained open 24 hours a day throughout the storm, even though only about 20 per cent of workers managed to show up Monday and Tuesday.
"They found a way to get here — I don't know how," store manager Jay Bilone said.
Insured losses from the superstorm will likely total $5 billion to $10 billion, the forecasting firm Eqecat estimates. Insurance losses are typically a fraction of the overall cost to the economy.
Chubb, Allstate and Travellers are the insurers most likely to suffer losses, said Greg Locraft, an analyst at Morgan Stanley. Those companies claim a major share of the affected areas.
"As an insurance event, Sandy is going to be a blip on the balance sheet," said Duncan Ellis, U.S. property practice leader at Marsh, the insurance broker. "2012 has been a relatively catastrophe-free year."
Economists expect actual property damages from Hurricane Sandy to exceed those caused last year by Hurricane Irene, which cost $15.8 billion. Irene had little effect on the nation's growth.
Sandy will likely be among the 10 costliest hurricanes in U.S. history. It would still be far below the worst — Hurricane Katrina, which cost $108 billion and caused 1,200 deaths in 2005.
But "there is every reason to believe that the hurricane won't kick the legs out of an already-fragile US economy," Caranci said.
