While many economists expect the Federal Reserve to begin tapering its quantitative easing (QE) soon and to end it by 2015, Marc Faber, publisher of the Gloom Boom & Doom Report, sees no termination point.

"The Fed will never end QE for good," he tells CNBC. "They will continue because these programs, once they're introduced, usually keep on going."

A Bloomberg survey of economists earlier this month showed that 34 percent anticipate tapering will start Wednesday, and 40 percent believe it will come in March.

"They [the Fed] may do some cosmetic adjustments, but in my view, within a few years, the asset purchases will be substantially higher than they are today," Faber predicts.

The central bank is buying $85 billion of Treasurys and mortgage bonds a month.

Some experts argue that the economy is growing strongly enough to make the Fed abandon its purchases, but Faber disagrees.

"The economic recovery, or so-called recovery, by June of next year, will be in the fifth year," he notes. "So at some stage the economy will weaken again, and at that point, the Fed will argue . . . 'we have to do more.'"

GDP expanded 3.6 percent in the third quarter.

As for the timing of tapering, "there's a balanced chance this happens in December or January," Carlos Pro, an interest-rate strategist at Credit Suisse in New York, tells Bloomberg.

"They are basically biased to slow down the pace of purchases."
