TOKYO, Aug 13 (Reuters) - Asian shares slumped on Tuesday as
fears about a drawn out Sino-U.S. trade war, protests in Hong
Kong and a crash in Argentina's peso currency drove investors to
safe harbours like bonds, gold, and the yen.
MSCI's broadest index of Asia-Pacific shares outside Japan
.MIAPJ0000PUS skidded 1%. Chinese stocks .CSI300 fell 1%,
while Hong Kong's .HSI main market index tumbled 1.7% to a
seven-month low.
"The protests in Hong Kong are negative for stocks, which
were already in an adjustment phase because there is talk that
the trade war will trigger a recession," said Kiyoshi Ishigane,
chief fund manager at Mitsubishi UFJ Kokusai Asset Management
Co.
Hong Kong's airport, the world's busiest cargo airport,
reopened on Tuesday after protesters managed to close it down
the previous day. The mood remained cautious as the increasingly
violent demonstrations have plunged the Chinese-ruled territory
into its most serious crisis in decades. The weeks-long protests began in opposition to a bill
allowing extraditions to mainland China but have quickly morphed
into the biggest challenge to China's authority over the city
since it took Hong Kong back from Britain in 1997.
Japan's Nikkei .N225 was also hit hard, down a sharp 1.2%
and on course for its biggest daily decline in a week.
In early European trade, the pan-region Euro Stoxx 50
futures STXEc1 were unchanged.
U.S. stock futures ESc1 were 0.23% higher in Asia, but
that did little to calm the fragile mood.
Stocks in Singapore .STI shed 1.1% to reach their lowest
since June 6 after the government slashed its full-year economic
growth forecasts. The city state is often seen as a bellwether
for global growth because of its importance as a key trade hub.
The selling in regional markets came as Wall Street stocks
took a beating on Monday, with the S&P 500 .SPX losing 1.23%.
Sentiment was already weak due to increasing signs that the
United States and China will not quickly resolve their year-long
trade war. Markets were hit with further turbulence after
protesters managed to close down Hong Kong's airport on Monday.
Traders were also on edge after market-friendly Argentine
President Mauricio Macri suffered a mauling in presidential
primaries, increasing the risk of a return to interventionist
economic policies.
Benchmark 10-year Treasury yields were near the lowest in
almost three years, gold was pinned close to six-year highs, and
the yen was within a whisker of a seven-month peak versus the
dollar in a sign of the heightened anxiety in financial markets
already battered by global growth woes.
"Long-term rates will continue to fall, and stocks will
adjust lower, but this is temporary. Major central banks are
cutting rates, which will eventually provide economic support,"
Mitsubishi UFJ's Ishigane said.
Analysts said that trading could be subdued as many
investors are off for summer holidays. Yet, there was no
shortage of gloomy news for investors looking to catch their
breath from several months of market ructions.
Argentina's peso ARS= collapsed on Monday, losing roughly
15% of its value to 52.15 per dollar after crumbling to an
all-time low of 61.99 earlier. Voters snubbed Macri by giving
the opposition a surprisingly bigger-than-expected victory in
Sunday's primary election. The Merval stock index <.MERV > crashed 30% and declines of
between 18-20 cents in Argentina's benchmark 10-year bonds left
them trading at around 60 cents on the dollar or even lower.
Refinitiv data showed Argentine stocks, bonds and the peso
had not recorded this kind of simultaneous fall since the South
American country's 2001 economic crisis and debt default.
The grim backdrop was enough to push investors into
safe-havens, and U.S. Treasury yields dropped across the board
on Monday as trade worries and political tensions supported
safe-haven assets.
In Asia on Tuesday benchmark 10-year Treasuries yields
US10YT=RR fell to 1.6403%. On August 7 yields had skidded to
1.5950%, the lowest since October 3, 2016.
Spot gold XAU= rose 0.47% to $1.518.43 per ounce, near the
highest in six years.
The yen JPY= last fetched 105.41 per dollar, and was
within striking distance of 105.03, its strongest since the
January 3 flash crash.
Oil prices edged slightly lower in Asian trading as
expectations that major producers will continue to reduce
supplies ran into worries about sluggish economic growth.
U.S. West Texas Intermediate futures CLc1 fell 0.22% to
$54.81 a barrel.
