WASHINGTON (Reuters) - Facing pressure to keep money printing in check, U.S. central bankers are mulling a modest approach to stimulus that would give the struggling economy only a tiny boost -- if it helps at all.

After two rounds of bond purchases that have pumped $2.3 trillion into the banking system, the Federal Reserve could buy long-term Treasury debt while selling short-term securities it already holds.
The idea, outlined by Bernanke in July, would be to lower long-term interest rates without increasing the money supply. That in theory could spur home purchases by lowering benchmark rates for mortgages. It could also make it cheaper for companies to borrow so they can buy more equipment.
Such a plan could also weaken the dollar and increase stock prices, which might boost exports and make people feel more positive about the economy.
But many analysts doubt growth would improve much unless the Fed injects a lot more money into the economy.
"I don't think the impact on the real economy is going to be meaningful" without more aggressive Fed action, said Troy Davig, a former Fed economist now at Barclays Capital in New York.
The Fed has already slashed overnight interest rates to near zero. Earlier this month, it said it thought it would keep rates low for at least the next two years.
Of course, it could still summon more dollars and inject them into the system, but higher inflation and political pressure create an imposing hurdle for such bold action.
That leaves relatively underwhelming options.
Davig crunched numbers for the Fed's last stimulus plan to pump $600 billion into the economy by purchasing government debt -- a program dubbed "QE2" -- and estimated it would add about a half percentage point to growth this year.
Federal Reserve Bank Chairman Ben Bernanke is likely to outline his options when he takes the podium at a conference in Jackson Hole, Wyoming, on Friday.
Yet Bernanke cannot work magic.
Even the most aggressive campaign to lower rates without printing money could add just a one or two tenths of a percentage point to next year's growth rate, Davig said.
Thomas Lam, an economist with OSK-DMG in Singapore, arrived at a similar conclusion, albeit considering a less-aggressive Fed strategy. Under that scenario, the Fed would reinvest money from maturing short-term bonds it holds into long-term assets.
Lam sees such a program adding between one and three tenths of a percentage point to growth over a year, and perhaps more if markets respond well to the measure. For example, by bringing down long-term Treasury rates, yield-hungry investors could pile into riskier assets like corporate bonds, making it cheaper for companies to borrow.
PUSHING ON A STRING
The Fed would likely launch some kind of bond-trading plan despite concerns it might not yield big results, analysts say. Every bit of growth helps.
Yet some are doubtful the Fed can do much at all by pushing interest rates lower.
Commercial real estate developer Andy Farbman couldn't get a loan recently to buy an office building in downtown Chicago worth just under $10 million. Despite all the money given to banks, lending standards have tightened since the financial crisis.
"It wasn't the cost of the capital. The capital didn't exist," said Farbman, president and chief executive of Southfield, Michigan-based NAI Farbman.
Because the loan wasn't there, Farbman paid cash, which meant less investment capital for other ventures.
Other companies aren't even interested in borrowing money because the weak economy is keeping consumer demand low. Similarly, the housing market keeps on weakening despite historically low interest rates.
In the parlance of economists, using monetary policy to boost growth is currently like trying to push on a string.
"What is a 2 percent 10-year yield going to do that a 2.5 percent 10-year yield didn't do?" said Jacob Oubina, an economist as RBC Capital Markets in New York, referring to the level of return on a 10-year Treasury note.
Oubina thinks QE2 was a net drag on the economy because in his view it pushed commodity prices higher. That might have led consumers to spend more on imported goods like fuel, dragging on gross domestic product.
Others are more optimistic. Economists at Goldman Sachs think an aggressive campaign by the Fed to buy long-term bonds while selling short-term assets might ease financial conditions almost as much as it thinks QE2 did, boosting real GDP growth by up to 0.3 percentage point in the year after any announcement.
That would be at least a bit of good news for U.S. companies.
"I'm not sure that we've seen any particular impact from QE1 or 2," said Hormel Foods Corp
"(But) if consumers can get more comfortable with their financial position, that's good for business, period."
