Biden drops out, China LPR

Asia-Pacific markets fell on Monday, as news emerged that U.S. President Joe Biden had dropped out of the presidential race, endorsing Vice President Kamala Harris as the Democratic nominee.

Investors will also assess the impact of the massive global IT outage on Friday. Machines running Microsoft’s Windows operating system crashed Friday due to a glitch in an update issued by cybersecurity company CrowdStrike, plunging its shares 11%.

Microsoft said in a blog post on the weekend it estimated that 8.5 million Windows devices — or less than 1% of all Windows machines — were affected. 

On Monday, focus will be on the People’s Bank of China’s loan prime rate decision, with the one-year and five-year loan prime rate expected to be unchanged at 3.45% and 3.95% respectively, according to economists polled by Reuters.

The one-year LPR acts as the benchmark for most corporate loans, and the five-year LPR serves as a reference rate for mortgages.

On Wall Street, all three major indexes retreated on Friday and U.S. stock markets wrapped up the week defined by a rotation out of this year’s mega cap winners in favor of smaller names.

The S&P 500 dropped 0.71%, while the tech heavy Nasdaq Composite slid 0.81%. The Dow Jones Industrial Average fell 377.49 points, or 0.93%, to 40,287.53.
