NEW YORK (Reuters) - Not long ago the Federal Reserve expected to quietly shed nearly half of its $4.5-trillion portfolio by around 2022, leaving little trace of the extraordinary steps it took to face down the financial crisis. But an unexpected market kink could force the Fed to scrap the plan two or three years early and permanently leave it holding $1 trillion more than it wanted.
The U.S. central bank is making adjustments on the fly and keeping its options open. “I don’t think that’s problematic in any way” to halt the process “somewhat earlier,” William Dudley, the former New York Fed president and key architect of the portfolio strategy, told reporters last month.
Yet if the world’s largest holder of U.S. bonds tossed out its play book and effectively took on a more accommodative stance, the result could be an across-the-board easing of market borrowing costs, the foreign-exchange value of the dollar, and of the growing strains on emerging markets.
“The evidence that we have suggests that the ultimate size of the balance sheet will be bigger than what people expected,” said Matthew Luzzetti, senior economist at Deutsche Bank Securities in New York.
All of this amounts to the final chapter in the Fed’s unprecedented decision over the last decade to buy some $3.5 trillion in mortgage and Treasury bonds in an effort to boost riskier investments, hiring and economic recovery from recession. In a nod to a stronger U.S. economy, the Fed since 2015 has raised interest rates well above zero and, since October of last year, begun shrinking its balance sheet to a more normal but yet-unspecified size.
