US August retail sales and manufacturing output fell more than expected.
Asian stocks firmed on Friday after weak US data reduced the already low chance of an interest rate increase by the Federal Reserve at next week's meeting, sending the Treasury yield curve surging to its steepest level in 2-1/2 months.
MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.3%, but it was headed for a loss of 2.4% for the week.
Japan's Nikkei advanced 0.4%, paring losses for the week to 2.9%, while Australian shares climbed 1.2%, on track for a weekly decline of 0.8%.
AT A GLANCE
* Weak US data reduce likelihood of Fed rate hike in September
* Treasuries yield curve steepens to most in 2 - 1/2 months
* South Korea, China, Taiwan, Hong Kong closed for holidays
* Swiss National Bank, Bank of England hold rates steady
* Oil futures pull back after Thursday's surge
South Korean, Chinese, Taiwanese and Hong Kong markets are closed for holidays.
US August retail sales and manufacturing output fell more than expected, data released Thursday showed. The lacklustre reports prompted the Atlanta Fed to lower its third-quarter gross domestic product estimate to a 3% annual rate, from 3.3% earlier.
"Anyone still left calling for a September hike next week from the Federal Reserve must be feeling a bit hot under the collar after further signs of economic vulnerabilities," Chris Weston, chief market strategist at IG in Melbourne, wrote in a note.
"It's no surprise to see reasonable buying in the short to medium duration US Treasuries, while the longer end of the curve hardly moved," he said.
The gap between five-year note yields and 30-year bond yields widened to as much as 130.10 basis points on Thursday, the steepest since June 27.
Futures traders are pricing in a 12% chance of a rate increase this month, down from 15% on Wednesday, according to the CME Group's FedWatch tool. Friday's consumer price inflation data is the next test for rates-focused traders.
The dwindling chances of a rate hike helped boost US stock indexes between 1% and 1.5% on Thursday.
Wall Street also benefited from a 3.4% jump in Apple shares, after the company said that the first batch of its new iPhone 7 Plus sold out globally.
Besides the Fed, the Bank of Japan also meets next week. The central bank will conduct a comprehensive review of its stimulus program after failing to reach its 2% inflation target.
Few Japanese companies see the central bank's aggressive monetary stimulus as achieving its stated goal of spurring inflation, a Reuters poll found, with firms citing negative fallout from the programme more than positive effects.
On Thursday, the Swiss National Bank and the Bank of England held interest rates steady.
The SNB warned that significant risks remain after sticking with its ultra-loose monetary policy and currency intervention, while the BOE said it is still likely to cut interest rates to just above zero this year.
In currencies, the dollar was little changed at 102.04 yen after Thursday's 0.3% loss, heading for a 0.6% decline for the week.
The dollar index, which tracks the greenback against a basket of six major peers, remained steady at 95.277, and set to end the week little changed.
The euro <EUR=EBS was also flat for both Friday and the week at $1.124.
Oil prices pulled back after Thursday's gains of as much as 2.5% as renewed risk appetite stemmed a two-day rout.
Both Brent crude and US crude retreated 0.5% to $46.35 and $43.68 a barrel, respectively.
Gold inched up after the resurgence in risk appetite pushed it down 0.7% on Thursday. Spot gold was last trading up 0.1% at $1,314.74 an ounce, but still down about 1% for the week.
