LONDON, Dec 6 (Reuters) - The dollar and the yen rose on Thursday
after the arrest in Canada of a top executive of Chinese tech giant
Huawei prompted fears of a flare-up in U.S.-China trade tensions.
The dollar has been under pressure over concern about a possible
But the arrest of Huawei Technologies Co Ltd's chief financial
officer increased safe-haven demand for the currency as doubts emerged
over a truce on trade struck days ago between Presidents Donald Trump
and Xi Jinping.
"Political quarrels outside the trade arena could jeopardise
the success of the trade talks... This is causing risk aversion to
rise again," said Esther Maria Reichelt, an FX strategist at
Commerzbank in Frankfurt.
As investors grew cautious and pulled back from riskier assets the
Japanese yen , often sought in times of market unrest, rose 0.4 percent.
Sharp losses in technology shares pulled down benchmark stock
indexes in China as the Chinese yuan slid 0.7 percent against the
dollar to 6.9037, its biggest daily fall since August.
The Australian dollar also fell more than one percent,
demonstrating its vulnerability to a worsening trade conflict due to
its export-oriented economy.
Against a basket of six rivals , the dollar edged up 0.2 percent
to 97.202. The currency has fallen 0.4 percent this week but is only
half a percent off a 17-month peak of 97.693 touched on Nov. 12.
The dollar fell broadly earlier this week after a thaw in trade
tensions between Washington and Beijing.
It has also been pressured by worrisome signs in U.S. bond markets
about economic growth and signals from the Federal Reserve that a
slowdown in the pace of interest rate hikes may be coming.
"The dollar could remain under pressure until this month's
Fed meeting when the market will see the Fed's stance on policy and
the economy," said Junichi Ishikawa, senior FX strategist at IG
Securities in Tokyo.
"The recent reaction to the U.S. yield curve inversion
appears a little hysterical, but the dollar will not be given the all
clear sign until the Fed meeting is hurdled."
Fed policymakers are still widely expected to raise interest rates
again at their Dec 18-19 meeting, but the market focus is on how many
rate hikes will follow in 2019.
The Canadian dollar fell as much as 0.6 percent to $1.3437, while
the Norwegian crown slid 0.7 percent against the dollar, pulled
down by fraying market sentiment and weak oil prices.
The yen rose to 112.645 against the dollar and made strides
against most of its peers.
The euro was slightly lower at $1.1328 after retreating from
this week's high of $1.1419 scaled on Tuesday.
