Asian stocks plunged on Tuesday after a record-breaking loss on Wall Street, extending a global rout as panicked investors fret over rising US borrowing costs and cash in profits after months of market euphoria.

Tokyo led a collapse throughout the region, diving more than five percent, with Hong Kong down more than four percent and Sydney sinking three percent.

Other assets were also hammered, with a slump in oil prices scything energy firms, while higher yielding currencies have been hit by a flight to safe havens.

Dealers tracked their colleagues in New York, where the Dow suffered its worst points fall in history, wiping out all its 2018 gains, while the S&P 500 also took a beating to sit down for the year.

Global stocks have enjoyed months of surges fuelled by optimism over the US economy, corporate earnings and the global outlook.

The winning streak was fanned by the passage of Donald Trump's massive tax cuts bill in December, which led several big-name firms to announce pay hikes and bonuses.

At the same time the economy continues to improve across the board.

Rising fear

But while traders have been piling into equities, pushing many global indexes to record or multi-year highs, there has been growing concern on trading floors about elevated US Treasury bond yields — at four-year highs — and the likelihood of fresh Federal Reserve interest rate hikes.

Selling kicked in on Friday when official data showed another jump in US jobs and a rally in wage growth, fuelling worries that inflation will surge this year and the Fed will be forced to hike rates more than expected this year.

The so-called Vix "fear" index more than doubled in US trade on Monday.

Among other Asian markets Seoul and Singapore were both down three percent, Taipei lost 4.5 percent, Manila plunged two percent and Shanghai gave up 2.1 percent.

Energy firms were among the biggest victims, with Inpex losing more than five percent in Tokyo, while CNOOC, PetroChina and Sinopec were down a similar amount in Hong Kong. Sydney-listed Woodside Petroleum was off more than three percent.

Tech giants were also targeted after disappointing earnings reports from Apple and Google parent Alphabet. Tencent, Sharp and Samsung all got a bloody nose.

And on currency markets the yen, considered a go-to unit in times of turmoil and uncertainty, climbed against the dollar. The greenback, however, rose against the pound and euro thanks to the expectations for rate hikes.

Bitcoin tanks

The commodity-dependent Australian dollar tanked one percent against its US counterpart, while South Korea's won, Indonesia's rupiah and the Mexican peso were among the other big losers.

And bitcoin continued its spiral downwards after some banks banned their customers from buying it with credit cards. The news is the latest to hit the cryptocurrency after recent crackdowns by authorities in India, South Korea, China and Russia.

The unit was down around 15 percent at $6,500, less than a third of its value near $20,000 in December, which sparked warnings of a bubble.

However, while trading floors are awash with red, analysts remained upbeat, saying the selling represented a much-needed correction.

Peter Garnry, head of equity strategy at Saxo Bank, who last month predicted a pullback, said: "We believe this is a healthy correction in equity markets but also likely short-lived as the higher US 10-year yield is still not in the danger zone."

And Sean Fenton, a portfolio manager at Tribeca Investment Partners in Sydney, told Bloomberg News: "I actually think there's buying opportunities, maybe not today, but through this week as this sell-off exacerbates."
