LONDON - The euro hit a 1-year high on Wednesday and German 10-year Bund yields continued to rise after doubling the previous day, as bets grew that the European Central Bank is readying to scale back its 2-trillion-euro stimulus program.

It was a lively European session. The bond market sell-off and jump in the euro came as a dive in technology stocks after the latest global cyber attack sent European shares to a two-month low.  

The euro was eyeing up $1.14 and was at a 7-month high versus the pound after an upbeat ECB President Mario Draghi on Tuesday opened the door to changing the bank's aggressive stimulus policy.

The common currency is now up almost 10 per cent this year. The head of the Federal Reserve, Janet Yellen, and one of her lieutenants, Patrick Harker, said on Tuesday that they expected to continue raising U.S. interest rates, but it couldn't rally the dollar.

That provoked the banking world's single biggest cheerleader for a stronger dollar, Deutsche Bank, to declare the end of the greenback's bull run which dates back to 2014.

"I do think the euro now has got quite significant momentum behind it and I think that will build toward the confirmation of some tapering announcement this year. So I would be long the euro on a tactical basis for the rest of the year," JPMorgan Asset Management's Global Market Strategist, David Stubb, said.

At the same time, core European bonds are the significant area of vulnerability to better euro zone growth and to changes in ECB policy, he added.

"If you are looking at a 10-year maturity and further out, it is a global bond market and the extremely low yields in core Europe stick out alongside Japan and Switzerland as the places that seem stretched in terms of valuation."

Amid all the choppiness, safe-haven gold rose for a sixth day in the last seven. Wall Street, meanwhile, looked set to struggle again after the S&P 500 and Dow Jones took their biggest tumbles in over a month. 

Nerves over the latest cyberattack, this time called Goldeneye, weighed on big tech names including Apple, Google-parent Alphabet, Facebook and Microsoft in premarket trading.

In Asia overnight, MSCI's broadest index of Asia-Pacific shares outside Japan dropped 0.4 per cent as it pulled back from a two-year high hit on Monday.

Japan's Nikkei ended down 0.5 per cent, as the yen, at 111.900, also took advantage of the dollar's weakness. The banking and insurance sectors however outperformed on expectations of higher rates.

The yield on U.S. Benchmark 10-year Treasury notes last stood at 2.22 per cent, well up from Monday's 2.14 per cent levels.

Federal Reserve chief Janet Yellen had said in London that it was appropriate to "gradually" raise U.S. rates, although there was an acknowledgement that inflation had seen some slippage.

"Yellen's comment is supporting Japanese financial stocks today, and for the long-term, Japanese stocks are on the rising trend supported by U.S.-led global economic recovery," said Mutsumi Kagawa, chief global strategist at Rakuten Securities.

Wall Street's drop on Tuesday saw it close at its lowest since May 31. It was spooked after the U.S. Senate delayed voting on a healthcare reform bill, rekindling worries about the timeline of Donald Trump's business-friendly policies.  

The dollar index, which gauges the U.S. currency against a basket of six major counterparts, edged down 0.2 per cent to 96.227, well below its previous session high of 97.447.

Euro bulls pushed it up 0.5 per cent to a one-year high of $1.1373 with FX traders waiting for another flurry of ECB policymaker speeches at a conference hosted by the central bank in Portugal.

The greenback also slumped against the Canadian dollar after Bank of Canada Governor Stephen Poloz told CNBC that it looked like the central bank's rate cuts have done their job.

Sterling, which has come under pressure again from Britain's recently volatile politics, bounced too, clawing above $1.28 to its highest since Prime Minister Theresa May lost her parliamentary majority on June 8.

Conversely, it hit its weakest since November at 88.79 pence per euro.

Emerging markets were caught in the global stocks sell off and commodities were also on the move.

Brent crude futures were down 0.2 per cent at US$46.55 per barrel. U.S. crude futures were down 0.5 percent at US$44.04.

The weaker dollar helped bolster spot gold, which was up 0.4 per cent at 1,251.59 per ounce, while industrial metals copper, lead and zinc prices dipped back from three-month highs a. 

"The market got ahead of itself in the first quarter with (hopes for) Trump's infrastructure plans, that's not happening now but against that China growth is ok," said SP Angel analyst John Meyer.
