Investors are looking with anticipation to a speech Friday by U.S. Federal Reserve Chairman Ben Bernanke at a retreat in Wyoming.
The Fed pledged earlier this month to keep interest rates super-low through mid-2013. Investors hope Bernanke will announce, or at least preview, further steps to help the economy including a third round of bond purchases known as quantitative easing.
"I think Ben Bernanke's meeting in Jackson Hole will be very much in focus here," said Tom Kaan, head of equity sales at Louis Capital Markets in Hong Kong. The consensus is that a third round of quantitative easing will come in some form, he said.
"The world is in a very dire situation at the moment," Kaan said. "People will react. Most of that reaction will come from fear."
Japan's Nikkei 225 index lost 1 percent to close at 8,628.13 -- a five-month low -- as a persistently strong yen rattled nerves. A strong yen hurts exports by making them more expensive.
Japan intervened in currency markets earlier this month to try to reverse the yen's climb. The decision to sell the yen and buy the dollar worked initially, sending the greenback toward 80 yen. But the dollar has been weighed down by the dimming outlook for U.S. economy and is back down to mid 76-yen levels.

Asian markets were the first to open after the developments in Libya, with the apparent crumbling of Moammar Gadhafi's regime after rebels entered the capital of Tripoli on Sunday. Oil prices are expected to fall if the situation can quickly stabilize.
Libya used to export about 1.5 million barrels of oil a day, but production all but ground to a halt in recent months as rebels battled to overthrow Gadhafi.
