HONG KONG, March 20 (Reuters) - The U.S. dollar edged
higher on Friday, but still headed for its biggest weekly fall
in 24 years on fears it will lose its status as the world's
reserve currency, while oil prices ceded ground after a recent
rally.
U.S. Treasuries were steady in Asian trade after yields on
Wednesday recorded their biggest single-day drop since the 1987
market crash on the Federal Reserve's surprise announcement it
will purchase $300 billion in longer-dated U.S. government
debt.
Asian stocks fell but looked set to gain for a second
consecutive week -- marking their best weekly back to back
gains since mid-December -- as the Fed's plan to inject a
combined $1.15 trillion into the U.S. financial system improved
battered confidence in the banking sector.
The Fed this week has tackled head-on the woes afflicting
the world's largest economy, but the approach has also created
uncertainties, mainly in the form of a weakening dollar and
prospects of surging inflation once the economy starts
recovering.
"This is a historic moment, the start of debasement of the
world's reserve currency, and it feels to many participants
that in the grand sweep of history we are witnessing the end of
'Rome' on the Potomac," said Alan Ruskin, a RBS strategist in
Greenwich.
The Fed's massive expansion of its balance sheet could lead
to an oversupply of the U.S. dollar and erode the safe-haven
appeal that just earlier this month had sent the currency to a
three-year high against a basket of currencies, analysts said.
In a day in which Tokyo markets were closed for a public
holiday, the U.S. dollar index <.DXY> gained 0.2 percent to
83.239 in early Asian trade, after falling as far as 82.631 on
Thursday to mark a 10-week low.
The dollar is still headed for a loss of around 5 percent
for the week against the basket of major currencies -- the
steepest fall since 1985 when major economies agreed to a
formal depreciation of the dollar in the Plaza Accord.
"U.S. dollars will be flooding the world as the printing
presses work overtime," said Stephen Koukoulas, a strategist at
TD Securities in London in a note to clients.
"Bye bye U.S. dollar. Sell sell U.S. dollar!"
The fall in the dollar has sent the euro to its biggest
weekly increase since its inception in 1999. On Friday the euro
was resting at $1.3655 <EUR=>, having climbed to about a
two-month peak of $1.3737 in New York.
The spectre that central banks will overdo in their fight
against falling prices, causing a big comeback of inflation, is
another concern.
The Fed's aggressive unconventional policy measures have
again pushed the central bank's balance sheet above $2
trillion, according to data released on Thursday.

U.S. Treasuries steadied in Asian trade after yields
dropped by the most in nearly 22 years after the Fed's
decision.
The 10-year yields were steady at 2.61 percent <RTRTSY1>,
having collapsed from 3.01 percent just before the Fed
announced its new plans on Wednesday and 2.90 percent at the
end of last week.
Two-year yields <US2YT=RR> were holding at 88 basis points,
compared to 1.03 percent before the Fed's move.
Asia-Pacific stocks outside Japan <.MIAPJ0000PUS> lost 0.9
percent on Friday though the index is headed for its second
consecutive weekly gain, bringing its advance for the month of
more than 9 percent.
Though regional banks have gained during that period, there
is plenty of concerns to keep optimism in check.
For export-dependent Asia, chief among them is the status
of global trade, while falls in the dollar could spark gains in
local emerging currencies just when manufacturers in the region
are facing a bleak prospect.
The global economy will shrink as much as 1 percent this
year -- its first contraction since World War Two -- the
International Monetary Fund warned on Thursday, urging quick
action to deal with problem assets on banks' balance sheets.

Prices for commodities rallied this week as the weakening
dollar made them cheaper for overseas investors, while others
looked for a hedge against potential inflation.
Still, oil prices <CLc1> dipped 56 cents to $51.04 a barrel
after a day earlier surging more than 7 percent to top the $51
a barrel mark.
Gold <XAU=> also eased to $951.40 an ounce from New York's
notional close of $958.60 after on Thursday rising to its
highest in nearly three weeks as investors
