Asia stocks extend rout after US selloff; Nikkei dives 4% on strong yen

Asian equity markets suffered heavy losses on Tuesday after Wall Street shares tumbled overnight as weak economic data sparked fears of a slowing U.S. economy.

U.S. stocks saw their worst start to February since 1933 after a manufacturing report heightened concern about the economy before Friday's monthly jobs report. Overall factory activity hit an eight-month low in January as new order growth plunged by the most in 33 years.

In a sign of heightened investor jitters, the CBOE Volatility Index rose above 20 on Monday for the first time in four months, while the yield on the 10-year Treasury note hit a three-month low.

"Suffice to say investors should steer clear of risk assets over the short term as the turmoil does not look like it will be over anytime soon. A combination of tapering, a confluence of country specific emerging market country concerns and weaker growth in China provide the backdrop for a volatile few weeks if not longer, ahead," said analysts at Credit Agricole.

Australia's benchmark S&P ASX 200 hit an eight-week closing low while the Australian dollar jumped as much as 1.4 percent to a near two-week high of $0.8875 against the greenback after the Reserve Bank of Australia left interest rates on hold, as expected.

Noticeably, the central bank dropped its easing bias in its monetary policy statement, saying that the most prudent course of policy was a period of stability in interest rates.

"A pick-up in the inflation rate to 2.7 percent year on year in the fourth quarter showed that the room for more easing is very much limited and we continue to think that the easing cycle already finished in August last year," wrote analysts at Credit Agricole in a report.
