[TOKYO] Asian shares and Wall Street stock futures turned negative on Wednesday after Pakistan said it had shot down two Indian jets in its territory, sending investors out of riskier markets and into more conservative choices such as the yen.
Islamabad said on Wednesday it had carried out airstrikes in Indian-controlled Kashmir and shot down two Indian jets in its own airspace, capturing one of the pilots as the risk of conflict between the nuclear-armed neighbours escalates.
The US dollar remained near a three-week low, weighed by earlier comments from Federal Reserve Chairman Jerome Powell who on Tuesday reiterated the central bank's shift to a more "patient" policy approach.
Indian bonds, stocks and the rupee all sold off. The flare up in geopolitical risks hit broader sentiment, driving investors out of stocks and into safe-haven assets with US stock futures slipping and the Japanese yen gaining.
"It shows to be one risk in Asia that was probably a little bit underestimated in the past," said Frank Benzimra, head of Asia equity strategy at Societe Generale in Hong Kong.
"With the events of the last few days, we're seeing now the market's paying closer attention."
MSCI's broadest index of Asia-Pacific shares outside Japan turned negative and was last down nearly 0.2 per cent, after trading in positive territory most of the day.
The news also weighed on European markets, with futures for London's FTSE and those for Frankfurt's DAX both down 0.4 per cent.
China's blue-chip CSI300 fell 0.2 per cent while Hong Kong's Hang Seng Index, reversed earlier gains to edge down 0.1 per cent.
Earlier in the Asian day, Japan's Nikkei share average finished the session up 0.5 per cent while Australian stocks gained 0.4 per cent.
US stock futures for the S&P 500 were last down 0.2 per cent. Trading in the contracts had been delayed for several hours following a technical disruption earlier in the session.
"There is a fear in the market that sentiment has got a bit carried away on the positive side, especially given the experiences we had through October and through December, when we had some really sharp downward corrections," said Nick Twidale, Sydney-based chief operating officer at Rakuten Securities Australia.
"A lot of investors are wary of seeing something along those lines," he added.
Powell, spelling out the Fed's approach to an economy that is likely slowing, told US lawmakers on Tuesday it is in "no rush to make a judgment" about further changes to interest rates.
In two hours of testimony to the Senate Banking Committee, Powell elaborated on the "conflicting signals" the Fed has tried to decipher in recent weeks, including disappointing data on retail sales and other aspects of the economy that contrast with steady hiring, wage growth, and ongoing low unemployment.
More evidence of the hot and cold economy came overnight, with weaker-than-expected US housing data and a rosy consumer confidence report.
US homebuilding tumbled to a more than two-year low in December as construction of both single and multi-family housing declined, which overshadowed the rebound in consumer confidence in February after three months of declines.
The contrasting data points left Wall Street underpowered, with the benchmark S&P 500, the Dow Jones Industrial Average and the Nasdaq Composite closing down 0.1 per cent each.
"Chairman Powell's comments were neutral and the economic data released overnight was mixed, insufficient to provide implications for the Fed's policy and directions to the market," said Yasuo Sakuma, chief investment officer at Libra Investments in Tokyo.
In the currency market, the US dollar was softer after the Fed chief's testimony, with its index against major peers dipping more than 0.4 per cent to its lowest in three weeks overnight. It recovered a little bit of ground in Asian trade, last trading 0.1 per cent higher at 96.138.
