Asia-Pacific stocks fell even after manufacturing data out of China bounced back to expansion territory.

China's factory activity in September expanded for the first time since April, according to official data over the weekend. China's PMI climbed to 50.2 in September from 49.7, beating Reuters' expectations of 50.0.

China's markets are closed for the weeklong Golden Week holiday. South Korean and Hong Kong's markets are also closed for holidays.

Japan's Nikkei 225 traded 0.31% lower to close at 31,759.88, while the Topix slipped 0.39% to end at 2,314.

Sentiment of Japan's big manufacturers improved to a score of 9 in the third quarter, up from 5 in the previous three months, the closely-watched central bank tankan survey showed.

Australia's S&P/ASX 200 was down 0.22% to end at 7,033.2.

On Friday in the U.S., the three major indexes were mixed. The Dow and S&P 500 finished the session lower by 0.5% and 0.3%, respectively, capping off a negative week for the two indexes. The Nasdaq Composite finished up 0.1%.

Over the weekend, U.S. legislators were able to reach a temporary agreement that averted a government shutdown.

Bank of Japan to increase bond purchases as as 10-year JGB yields hit decade peak

The Bank of Japan announced on Monday said it will be increasing its bond purchases at Wednesday's auction, as a spike in government bond yields tests the central bank's resolve to defend its yield curve control policy.

The BOJ will conduct an unspecific amount of additional purchases of Japanese government bonds with tenures of more than five years and up to 10 years.

Yields on 10-year Japanese government bonds hit as much as 0.775% Monday, its highest since September 2013.

"While the Chinese economy is weak, it's certainly not in crisis or collapsing," Andy Rothman, investment strategist at Matthews Asia, told CNBC's "Squawk Box Asia."

Rothman added that he can see "a lot of green shoots," highlighting that China's consumer and services sector is faring well.

"In the first seven months of this year, consumer spending on services was up 20% year over year. That part is booming," he said.

Bank of Japan board discussed factors for exiting ultra-loose policy, September meeting summary shows

The Bank of Japan's policymakers evaluated a number of conditions that must be met before ending the central bank's ultra-loose policy during its September meeting.

"Sustainable and stable achievement of the price stability target, accompanied by wage increases, has not yet come in sight, and thus the Bank needs to patiently continue with monetary easing under yield curve control," the BOJ's summary of opinions stated.

One board member highlighted how the second half of the fiscal year ending March 2024 will mark an "important period" for determining whether the price stability target will be achieved.

"Even if the Bank were to terminate its negative interest rate policy, this can be considered as continuation of monetary easing if real interest rates remain negative. It is important for the Bank to carefully provide communication on this," another board member was quoted saying.

In September, Japan's central bank held its stance and left rates unchanged, on the back of "extremely high uncertainties" on the growth outlook domestically and globally.

China reports factory activity expansion in September

China's factory activity in September expanded for the first time April, data from the National Bureau of Statistics showed on Saturday.

China's PMI climbed to 50.2 in September from 49.7 in the previous month, beating Reuters' expectations of 50.0.

A reading above the 50-point level marks an expansion, while a figure below the 50-mark indicates a contraction. China's non-manufacturing PMI also inched up to 51.7 from a previous reading of 51.

Similarly, a private-sector survey reflected an expansion in China's factory activity, albeit at a slowed pace.

The Caixin/S&P Global manufacturing PMI dipped to 50.6 in September from 51.0., the survey showed on Sunday, missing forecasts of 51.2.

"Manufacturing conditions across China improved slightly for the second consecutive month in September," the press release stated.

"However, confidence regarding the year-ahead remained relatively subdued, which in turn contributed to a drop in employment at Chinese manufacturing plants," the report added.

Lawmakers avoiding shutdown should be good for markets, financial group partner says

Lawmakers were able to pass a continuing resolution and evade a government shutdown on Saturday. The bill keeps the government operating for 45 more days, allowing more time for legislators to finalize funding proposals.

This development should be welcome news for the market and offer a boost coming off a tough week, according to Jamie Cox, managing partner at Harris Financial.

"There'll be a lot of unwinding of government shutdown selling from last week, which will be good," he said.

Aluminum prices hit multi-month high as winning month nears end

Aluminum prices hit a high not seen in multiple months in the final trading day of what's shaping up to be the best month since January.

The metal traded as high as $2,334 per metric tonne. That's the most expensive since May 9, when it reached $2,338.50.

Aluminum is up about 4% week to date. If that holds, it would mark its fifth winning week out of the last six.

Those gains have pushed the metal up about 5.7% on the month, with just Friday's session left. That performance marks the best since January, when aluminum gained around 11.2%.
