Central banks lead subtle shift away from dollar

By Steven C. Johnson - Analysis

NEW YORK (Reuters) - Central banks with trillions of dollars in reserves that are already stepping up euro and yen purchases will likely continue doing so in coming years, driven by worries over the stability of the greenback.

A record U.S. budget gap and the rise of dynamic developing economies like China suggest the dollar, down over 20 percent since 2002 on a trade-weighted basis, has further to fall.

Of course, the dollar comprises some two-thirds of global reserves and will remain dominant in most holdings, as attempts to dump it would destroy the value of central bank portfolios.

But with the speed of reserve accumulation increasing after a crisis-induced lull late last year, policy makers can choose to park more new cash in euros and yen without having to sell existing dollar assets.

"I think 2009 will be remembered as a watershed moment for currencies," said Neil Mellor, strategist at BNY Mellon, which has some $20 trillion in assets under custody. "I don't think there will be an imminent move, but it is quite clear there's a plan to shift reserves to a more balanced portfolio."

Barclays Capital research showed that central banks that report reserve breakdown put 63 percent of new cash coming into their coffers between April and July into non-U.S. currencies.

"There's an incipient desire to reduce the dollar share of reserves, and central banks will use any opportunity to do it, provided it doesn't cause the dollar to fall out of bed," said Steven Englander, chief U.S. currency strategist at Barclays.

International Monetary Fund data shows the dollar's share of known world reserves has been declining since it stood at 72 percent in 1999, the year the euro was introduced. As of the second quarter of 2009, it accounted for 62.8 percent.

To be sure, some of that shift is driven by the dollar's decline against a basket of currencies over that period.

But the Barclays data, which removes valuation effects, shows the second quarter was the only one in which central banks accumulated more than $100 billion in reserves and put less than 40 percent into dollars, down from a 70 percent quarterly average back to 2006.

Overall reserves rose 4.8 percent to $6.8 trillion in the second quarter, the IMF said, the first increase in a year.

CATCHING UP TO THE DOLLAR

Policy makers acknowledge the dollar will remain a linchpin of global finance for many years to come. But it has fallen steadily on a trade-weighted basis over the last decade, a troubling sign for China, Russia, India and other big U.S. creditors holding trillions of dollars of U.S. Treasury debt.

Worries about record deficits, run up as the United States borrowed hundreds of billions to stimulate an economy ravaged by financial crisis, has further diminished foreign demand for U.S. assets, making it likely the dollar will weaken further.
