Sydney: Asian shares skidded on Monday with investors rattled by rising bond yields and talk the Federal Reserve might be serious about lifting U.S. interest rates as early as next week.
Reports that the Bank of Japan was considering ways to steepen the Japanese yield curve, along with speculation that central banks more generally were running short on fresh stimulus options, also hit sovereign debt and risk appetite globally.
MSCI's broadest index of Asia-Pacific shares outside Japan fell 2.2 per cent, pulling away from a 13-month peak. It was the largest daily drop since the frenzy caused by Britain's vote in late June to leave the European Union.
Shanghai followed with a fall of 1.7 per cent, while Australian stocks sank 2.2 per cent. The Nikkei 225 lost 1.5 per cent as the yen firmed due to risk aversion and yields on 10-year JGBs briefly hit the highest since March before paring losses.
Traders were unsure how the BOJ would try to steepen the yield curve if it goes down that path at a policy review later this month, but markets are worried that tapering of its buying in long-dated bonds could be among the options.
EMini futures for the S&P 500, traded in Chicago during Asian hours, also swung 0.6 per cent lower, though Treasuries were finding safe-haven demand.
Some Fed members have been trying to convince markets that the September meeting would be "live" for a hike, even though futures only imply a one-in-four chance of a move.
No less than three Fed officials are expected to speak later in the global day, including board member and noted dove Lael Brainard. Any hint of hawkishness would likely further pressure bonds and equities.
"Market participants are wondering if maybe she's (Brainard) being wheeled out to give the market one last warning of a rate hike at next week's meeting," said Marshall Gittler, head of research at broker FXPRIMUS.
"The thinking is that if someone as dovish as she is starts talking like a hawk, people will notice. Her speech will be closely examined."
Such risks led the Chicago Board Options Exchange Volatility index to close at its highest level since late June on Friday. The Dow shed 2.13 percent on Friday, while the S&P 500 lost 2.45 per cent and the Nasdaq 2.54 per cent.
Super-low yields have made returns on equities seem relatively more attractive in comparison, so any sustained climb in yields would likely weigh on stock valuations.
The yield on benchmark German debt, for instance, had turned positive for the first time since July 22 and ended at 0.02 per cent, its highest since June 23. Yields on U.S. 10-year and 30-year paper hit 11-week peaks.
Seeking safety
In the forex market, the sudden bout of risk aversion benefited safe havens such as the yen while hitting carry trades in higher yielding currencies including the Australian dollar.
The Aussie has lost 1.5 per cent against the yen in two sessions to stand at 77.21, while the Japanese currency was firm on the U.S. dollar at 102.55.
The euro was sidelined on the dollar at $1.1239 after weak German trade data dragged it down from $1.1271 on Friday. The dollar index, which tracks it against a basket of six currencies, eased fractionally to 95.317.
Adding to the jittery mood on Monday was news that Democratic candidate Hillary Clinton fell ill at a Sept. 11 memorial ceremony and had been diagnosed with pneumonia.
Markets have generally assumed Clinton would win the presidency and have not truly considered the implications, both economic and for national security, should Donald Trump prevail.
Geopolitical concerns had already been inflamed by North Korea's fifth and biggest nuclear test, ratcheting up a threat that its rivals and the United Nations have been powerless to contain.
North Korea has completed preparations for another nuclear test, South Korea's Yonhap News Agency reported on Monday, citing South Korean government sources.
In commodities, oil prices extended Friday's 4 percent fall in Asia after reports showed increasing oil drilling activity in the United States, indicating that producers can operate profitably around current levels.
Brent crude was off 70 cents, or about 1.5 per cent, at $47.31 a barrel, while U.S. crude lost 79 cents to $45.09.
