* Asian currencies sharply reverse weeks of gains
* South Korea won at 3-mth low on stock investment outflows
* Taiwan dlr hits 4-mth low on foreign financial outflows
By Jongwoo Cheon
SINGAPORE, Jan 28 Foreign portfolio outflows
from South Korea triggered a round of heavy selling in Asian
currencies on Monday, driving the largest daily fall in the won
in 16 months and raising the spectre of sustained volatility in
the region's currency market.
The won fell 1.7 percent against the dollar, its largest
daily percentage fall since Sept. 26, 2011. The Taiwan dollar
slipped to its weakest in more than four months.
Foreign investors reported their largest daily stock sales
in 16 months on Korea's KOSPI index.
Currency analysts said the sharp decline in the Asian
currencies appeared to be driven by a combination of factors:
profit-taking by foreign portfolio investors, the euro's rally
on Friday and some concern that the regional units had risen too
far against a weakening yen.
While those factors do not detract from the fundamental
attractiveness of Asia's growth and high-yielding markets, the
risk was that foreign capital outflows would lead to contagious
currency depreciation, helped by regional authorities concerned
about the erosion of competitiveness versus the yen, they said.
"There could be some further pullback in Asian FX. A higher
dollar/yen will drag the rest with it and Asian central banks
will be happy to see some local currency weakness," said a
senior U.S. bank trader in Singapore.
Until recently, Asian currencies were major targets of
investors looking for higher yields with cheap money printed by
major central banks, especially the Bank of Japan (BoJ).
Last week, the BoJ announced its most radical effort yet to
end years of economic stagnation, after weeks of relentless
pressure from new Prime Minister Shinzo Abe for a greater push
to lift the economy out of recession.
That push for aggressive monetary easing has pushed the yen
down. On Monday, the dollar climbed as far as 91.25 yen, its
highest level since June 2010.
Asian currencies have been climbing against the yen, giving
policymakers in Korea and China much angst over a loss of
competitiveness. The won fell below the 12-per-yen level this
month, a level deemed highly sensitive for Korean electronics
exporters, before South Korean authorities stepped up rhetoric.
On Saturday, Bank of Korea Governor Kim Choong-soo said
Japan's monetary easing had "created problems".
Last week, China's foreign exchange regulator warned of
speculative capital inflows.
"The currency war story is starting to grab some attention
and people are buying dollars ahead in anticipation of weakening
of Asian currencies to catch up with the yen," said a European
bank dealer in Manila.
HOT MONEY OUTFLOW
The won had risen 12.4 percent against the dollar between
late May and mid-January. It has been slipping since
mid-January, losing 3.6 percent. Monday's close of 1,093.5 to
the dollar was the weakest since Oct. 30 last year.
Implied volatility on the won, priced into one-month
options, jumped on Monday, rising 3 percentage points to above 9
That would be a warning sign for the region's central banks,
most of which have stated that they are apprehensive of big
swings in their currencies, not about fundamental weakness or
"To me what the authorities get angry about is very rapid
moves, as we have seen recently," said Jonathan Cavenagh,
strategist at Westpac Banking Corporation.
"Once the dust settles, I think most countries around this
region won't be afraid of currency strength but would prefer it
in a gradual manner."
Yet some currency traders were preparing for the won's slide
to accelerate repatriation from the country's stocks.
"We'd better prepare for a level of 1,100 soon," said a
senior foreign bank dealer in Seoul.
The Indonesian rupiah slid more than half a percent and was
traded at levels around 9,790-9,800, although the central bank
was spotted providing dollars to the market, traders said.
Westpac's Cavenagh said it seemed like Monday's move was
merely a market shedding some heavy bullish positions in Asian
currencies, rather than any shift towards being short in the
