Taper-lite signals Fed's support to US economy: Experts

* The Fed trimmed equally from mortgage and Treasury bonds, reducing to USD 35 billion in mortgage securities and USD 40 billion in Treasury bonds.

* The Fed's asset purchase program, a centerpiece of its crisis-era policy, has left it holding roughly USD 4 trillion of bonds, and the path it must follow in dialing it down is rife with numerous risks, including the possibility of higher-than-targeted interest rates and a loss of investor confidence.

COMMENTS: DANIEL HECKMAN, SENIOR FIXED INCOME STRATEGIST AT U.S. BANK WEALTH MANAGEMENT, KANSAS CITY, MISSOURI:

"A lot of people had gone short into this meeting expecting some announcement even if they had not felt confident in voicing that. Ultimately, this will allow the yield curve to steepen a little bit more especially if we get some more encouraging economic data. The announcement is bond-market friendly in terms of the limited size of the tapering so we're seeing some short-covering.

RICHARD FRANULOVICH, SENIOR CURRENCY STRATEGIST, WESTPAC, NEW YORK:

"The forward guidance from the Fed has offset the tapering announcement. The Fed has come along and said we won't be hiking until we're well past 6.5 percent in the unemployment rate. That pretty much did it for the dollar."

BRIAN J. JACOBSEN, CHIEF PORTFOLIO STRATEGIST, INVESTMENTS GROUP, WELLS FARGO FUND MANAGEMENT, MENOMONEE FALLS, WISCONSIN:

"It's going to be a bunny hill, not a cliff for QE3. It will slowly fade into the distance as the labor market continues to slowly heal. QE3 didn't do much to affect inflation, which is why the Fed is enhancing its forward guidance. Even that enhancement might not be enough to make a material difference."

ERIK DAVIDSON, DEPUTY CHIEF INVESTMENT OFFICER, WELLS FARGO PRIVATE BANK, SAN FRANCISCO:

"We were surprised about the decision to taper, but given the news this (market move) was as we expected. It was almost a no-lose situation with the uncertainty removed from the market place.

"The reason the market is up as it is is this is 'bad news' investors have been waiting for and is finally out of the way. It is fodder for possibly better markets because it affirms the economy is healing.

The Fed "enters into this very cognizant of the impact of turning it off and on, much like a company would do when declaring a dividend. It is safe to assume that absent some severe externality we are on pace for a steady tapering."

FRED DICKSON, CHIEF MARKET STRATEGIST, D.A. DAVIDSON & CO., LAKE OSWEGO, OREGON:

"The mystery in terms of when the Fed would initially begin the rate of reducing bond purchases is off the table heading into the new year, and the initial amount is small - it's barely tapering. And, it was accompanied by a more positive assessment of the current economic situation.

"I'd say the markets have taken the announcement in good shape."

ANDREW WILKINSON, CHIEF ECONOMIC STRATEGIST, MILLER TABAK & CO. LLC., NEW YORK:

"The Fed shaved USD 5 billion from each of its bond purchase programs and so announced the onset of tapering at two-times the pace we had anticipated. Within the statement there is little change in the tone - unemployment remains elevated but is improving, while the restraint from fiscal policy maybe diminishing. Inflation remains stable.

"With ongoing policy accommodation the Fed expects to witness growth pick-up from its recent pace and for unemployment to gradually decline consistent with its dual mandate. Risks to the economic outlook are more balanced it noted. A pyrrhic victory for those who feared inflation was a reason to hold off from tapering - the FOMC noted that inflation persistently below its 2 percent objective could pose risks to economic performance. Its focus is on watching for signs of an expected return to target."

DAVID JOY, CHIEF MARKET STRATEGIST, AMERIPRISE FINANCIAL, BOSTON:

"I am surprised the Fed chose to move today. Certainly they can justify the decision. However, I expected them to wait another meeting or two to ensure that the recently strong economic data was sustained.

"Nevertheless, tapering was going to happen eventually. In the larger scheme of things, this is a vote of confidence in the economy and represents the first step toward monetary policy normalization. The forward guidance on rates was dovish, as the Fed endeavors to minimize any negative fallout from the decision to taper. The bond market appears to be taking the decision in stride, suggesting that this move had been well discounted, while stocks have risen in an apparent reaction to the better economic outlook that the Fed has just endorsed. The dollar is firming as might be expected.

"However, initial reactions can often times be deceiving, so how markets close today, and react in the days ahead, will be important."

ERIC GREEN, GLOBAL HEAD OF RATES AND CURRENCY RESEARCH AND STRATEGY, TD SECURITIES, NEW YORK:

"It was a bit surprising in that they chose December over January... everything was in place for them to taper, they had all the evidence they needed to taper at this point in time, but we thought they would probably choose to do it in January.

"It is a small taper, but it means they can proceed in January with another USD 5 billion to USD 10 billion if they choose, which means you are at a USD 20 billion mark where we thought we would have been at the end of January, but we are just starting a little earlier. This is a good move for policy in that QE is looking increasingly like an anachronism in the current environment, and if it's anachronistic and they don't like it then it's well past the time that they should move away from it."

ERIC STEIN, CO-DIRECTOR, GLOBAL INCOME GROUP, EATON VANCE INVESTMENT MANAGERS, BOSTON:

"The Fed didn't change the unemployment threshold, but they made the forward guidance somewhat more dovish, saying rates will be near zero well past 6.5 percent. Also, the expected fed funds rate as of December 2016 is now 1.75 percent versus 2 percent. So that language is somewhat more dovish than before. U.S. Treasury yields rose when the statement first came out, but are now lower than they were before the announcement."

RICK MECKLER, PRESIDENT OF HEDGE FUND LIBERTYVIEW CAPITAL MANAGEMENT LLC IN JERSEY CITY, NEW JERSEY:

"They finally pulled a Band-aid off that they've been tugging at for a long time. The initial reaction is that tightening will be bad for stocks, but upon further reflection investors realize that to some extent tightening represents a view that the economy is stronger and can survive higher rates.

"This is a market that for a long time has wondered if good news is bad news or bad news is good news. If the Fed feels we've gotten to a point where they can begin to withdraw some of the stimulus there's at least some positive thought that we're in better economic shape and therefore stocks can do better."

AXEL MERK, PRESIDENT AND CIO, MERK INVESTMENTS, PALO ALTO, CALIFORNIA:

"You can call this tapering, but they still haven't given us a real end point. They're just caving into market pressure to do something. But real tapering would have involved giving an end point for when they will stop increasing the balance sheet. They're still giving the impression that they'll be late raising rates, so I'm not sure how hawkish this really is."

MICHAEL WOOLFOLK, SENIOR CURRENCY STRATEGIST, BNY MELLON, NEW YORK:

"This was a surprise to me and I think to the market. We've had some understandable volatility in the currency market. Bond yields rose but it doesn't appear we'll hit 3 percent in the 10 year today. It seems clear that (Fed Chairman Ben) Bernanke, on his way out, wanted to set the machinery in motion and break down any resistance to getting started.

"It's certainly supportive for the dollar, though we are a little concerned about how the stock market is going to take this. As for the Fed, the September disappointment and the December surprise have really called into question the efficacy of the Fed's transparency."

WAYNE KAUFMAN, CHIEF MARKET ANALYST AT ROCKWELL SECURITIES IN NEW YORK:

"Cutting the amount by USD 10 billion is a good signal that QE won't be a forever thing. I think people were prepared for this, and I think they are relieved that the Fed is starting. No one wanted this 800-pound gorilla in the market; I wanted them to start tapering in September. I'm not surprised to see markets rebound, since we've already seen a lot of weakness recently. Before today, we only had two positive sessions this month."

MARKET REACTION:

STOCKS: US stock indexes initially fell before rebounding, and turning substantially higher

BONDS: US bond prices initially added to losses, then reversed to nearly unchanged

FOREX: The dollar rose against the euro before reversing, with the euro now higher
