LONDON, Jan 5 (Reuters) - The dollar fell against a basket
of major currencies on Tuesday after China lifted its official
yuan exchange rate to its highest level in 30 months, helping
support demand for other currencies.
China's central bank set the official yuan midpoint
CNY=PBOC at 6.4760 per dollar before the market opened, up %
from the previous fix, also the biggest change since 2005.
In the offshore market, the yuan strengthened as far as
6.4419 CNH=EBS for the first time since June 2018. It started
the week at 6.4944.
"If the Chinese currency is going up, it's providing a
degree of support for Asian currencies in general, and I suspect
that's why the U.S. dollar is partially reversing the gains that
we saw from Wall Street time," said Ray Attrill, head of FX
strategy at National Australia Bank in Sydney.
"It's a very big move by any historical yardstick, and I
don't think you can ignore that."
While investor caution about the yuan's rally prompted some
later selling of the Chinese currency on Tuesday, the PBOC's
action nonetheless lifted risk sentiment in currency markets.
Among G10 currencies, the Australian dollar led gains as the
move by the People's Bank of China (PBOC) encouraged broad
dollar selling.
The dollar index weakened 0.2% to 89.731. It dropped as low
as 89.415 on Monday for the first time since April 2018, but
ended the day with a 0.1% gain after U.S. stocks slid.
Earlier, the dollar had found support as concern about
surging COVID-19 cases and uncertainty about U.S. runoff
elections in Georgia spurred a retreat in U.S. stocks from
record highs to start the year and kindled demand for safer
assets.
Still, strategists appear convinced of protracted weakness
for the dollar.
"While rising COVID cases remain the key near-term risk, as
has been the case in the latter part of 2020, the market
continues to focus on the prospects of the vaccine and the
eventual global economic recovery," ING Bank said in a note to
clients.
"While a possible Democratic victory (in Georgia) could
raise concerns about more regulation, at least over the coming
months this might be outweighed by expectations of larger fiscal
stimulus and thus keep risk assets supported and the dollar weak
over the coming months."
The Aussie dollar, a barometer of risk appetite that also
tends to follow the yuan, jumped 0.7% to 77.18 U.S. cents AUD=
during trade in London, approaching the 2-1/2-year high of 77.43
touched on the final day of 2020.
The dollar fell 0.3% to 102.86 yen JPY=EBS . It dropped as
low as 102.715 on Monday for the first time since March.
The euro rose 0.2% to $1.22765 EUR=EBS after reaching
$1.231 on Monday, its highest since April 2018.
The British pound gained 0.1% to $1.3573 GBP= .
Sterling has been swung by a surge in infections of a
fast-spreading new coronavirus strain in the UK, with Prime
Minister Boris Johnson ordering another nationwide lockdown.
It slid 0.73% on Monday, the most since Dec. 10, after
earlier rising to $1.3703, a level not seen since May 2018.
Bitcoin traded at $31,367 BTC=BTSP following a
roller-coaster ride to start the new year that took it to a
record high of $34,800 on Sunday, followed by a tumble to as low
as $27,734 the following session.
