A reduction in the reserve requirement ratio for the banks of the People's Bank of China (PBOC) came into effect on Monday. The PBOC announced in early September that its reserve requirement ratio would be reduced by 50 basis points and that it would continue to reduce it by 100 basis points for some qualified banks. This should release 800 billion yuan (113 billion US dollars) of liquidity into the economy.

At the same time, Hong Kong's Hang Seng index lost 1%. Shares of Hong Kong Exchanges and Clearing lost 2.08% following the rejection of its takeover bid by the London Stock Exchange Group last Friday.

The Australian S & P / ASX 200 was slightly higher, with the majority of sectors recording a decline in trade, with the exception of the energy subindex, which jumped more than 4% in because of soaring oil prices.

In South Korea, the Kospi grew by 0.46% while chip maker SK Hynix plunged more than 3%.

Over the weekend, drone attacks hit the heart of the Abqaiq and Khurais oil production facilities in Saudi Arabia, claimed by Houthi rebels in Yemen. Half of the country's oil production has been halted due to damage caused by a fire and an assessment of the situation is expected on Monday, officials at the Saudi Ministry of Energy said.

The national oil company, Saudi Aramco, is trying to restore about a third of its crude output by Monday as a result of the attacks, the Wall Street Journal reported Sunday.

The strategists of the Commonwealth Bank of Australia have said that the rise in crude prices may not last.

"The drone attacks hit the oil market at a time when there is a global glut of oil and weak global growth," they wrote in a note. "As a result, the impact on oil prices and global growth should not be significant nor last long."

China's industrial production growth was the slowest in 17.5 years in August, rising only 4.4% year-on-year.

This is lower than the forecast of a 5.2% increase from one year on the other by analysts from a Reuters survey. The growth of industrial production in the country fell to its lowest level in more than 17 years in July.

"I think the Chinese economy is bottoming out." Said Leon Goldfeld, multi-asset portfolio manager at JP Morgan Asset Management, on CNBC's Street Signs.
