* Sterling on the up after new Brexit deal reached
* British PM still needs to get deal through parliament
* Yuan in focus before China GDP as trade war bites
By Stanley White
TOKYO, Oct 18 (Reuters) - The British pound traded near a
five-month high against the dollar and the euro after British
Prime Minister Boris Johnson and European Union leaders agreed a
new deal for Britain to exit the bloc.
Sterling's gains on the dollar helped push the greenback to
a five-month low versus the euro and a three-week low against
the Swiss franc.
The yuan held steady against the dollar in offshore trade
before the release of China's GDP data. Economists have forecast
the economy will grow at the weakest pace in more than 27 years
in the third quarter due to a costly trade war with the United
States.
The initial relief at securing the long-awaited Brexit deal
could be brief, however, because the prime minister still needs
to sell the agreement to sceptical lawmakers when parliament
sits on Saturday. Once Britain does leave the EU, its economic growth is
expected to slow, which is likely to be a negative for sterling
in the longer term, analysts warn. []nL5N27262N]
"Assuming we clear the parliamentary hurdle, the pound has
room to rise further because there are a lot of shorts to be
unwound," said Takuya Kanda, general manager of the research
department at Gaitame.com Research Institute in Tokyo.
"But after that, people will start to question whether this
is really good for Britain's economy, and further gains in
sterling could become difficult."
The pound GBP=D3 traded at $1.2870 in Asia on Friday,
close to a five-month high of $1.2988 reached on Thursday after
EU leaders unanimously backed the new Brexit deal with Britain.
Against the euro EURGBP=D3 , sterling traded at 86.42
pence, near a five-month high of 85.77 pence.
For the week, the pound was on course for a 1.7% gain versus
the dollar and a 0.9% increase against the common currency.
Britain's new Brexit deal has a "decent chance" of clearing
parliament on Saturday, finance minister Sajid Javid said, but
some investors are wary because debate so far on Brexit has been
fractious and difficult to predict.
Even if Johnson can win approval in parliament, Britain is
still on course for more distant economic ties and increased
trade barriers with the EU, which many economists say will slow
growth in the UK.
For now, sterling's gains and worries about weak U.S.
economic data are pushing the greenback lower against other
currencies.
The dollar traded at 0.9875 Swiss franc CHF=EBS , close to
the lowest since Sept. 25 and on course for its biggest weekly
decline since Aug. 9.
The dollar JPY=EBS was quoted at 108.57 yen, headed for
its second week of gains.
In offshore trade, the yuan CNH=D3 traded at 7.0815 per
dollar.
China is expected to post its weakest economic growth in at
least 27-1/2 years in the third quarter when Beijing releases
gross domestic product data at 0200 GMT.
Downbeat data in recent months has highlighted weaker demand
at home and abroad, fanning expectations that Beijing will need
new measures to ward off a sharper slowdown due to a year-long
trade war with the United States.
The world's two-largest economies have imposed tariffs on
each other's goods in a dispute over China's trade and
industrial policies that has slammed the brakes on global
economic growth.
